🔧 Component Overview

The DJI Agras T100 OEM Spinner Disk is the OEM spinner disk in the spinner disk assembly of the DJI Agras T100, part of the structure metering and throwing granular material in a controlled swath.

Metering and throwing granular material in a controlled swath is the job description for the spinner disk assembly, and this component is part of how it gets done. The T100 is a working machine — it earns its keep in fill-and-fly cycles, not hangar hours — and every component in the spinner disk assembly is sized, shaped, and specified around that duty. On the official parts diagram it sits alongside Thumb Nut, R-Type Pin, Screw (M40-HC080080-68-85).

Ignore a failing spinner disk and the bill compounds: downtime in the middle of an application window, collateral wear on the parts around it, and jobs that slip to a competitor while the aircraft sits. Replacing it costs a part; not replacing it costs acres. That trade only runs one direction.

For professional farmers, aerial applicators, and commercial drone operators, this component is how the spinner disk assembly stays field-ready instead of becoming the reason the aircraft sits.

This is a working part on a working aircraft.

The T100 works brutally hard for its living, including:

• Metering and throwing granular material in a controlled swath
• Dawn-to-dusk spray campaigns during narrow application windows
• Repeated fill-fly-return cycles with minutes on the ground between loads
• Full-payload takeoffs from field edges, dozens of times per day
• Chemical exposure from fungicides, herbicides, insecticides, and foliar fertilizers
• Pressure-washer rinse-downs at the end of every spray day
• Vibration from eight propulsion motors running at working power
• Transport bouncing on trailers and truck beds between fields
• Temperature swings from cold morning starts to full-sun afternoons

What attacks this component in the field:

• Vibration from the propulsion system every flight hour
• Chemical exposure from spray drift and washdown
• UV degradation across a season outdoors
• Shock loads from field-edge landings
• Grit and dust working into interfaces
• Thermal cycling from dawn starts to afternoon heat
• Stress concentration at mounting points
• Wear from repeated maintenance access

That duty cycle is exactly what retires this component. None of these stresses is dramatic on its own — the accumulation is what does it. This is why structural and mounting parts are inspection items every time the spinner disk assembly is opened up, and why operators who run hard keep spares on the shelf.

A healthy spinner disk delivers:

• Factory-correct fit in the spinner disk assembly — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored function you can verify on the first post-repair check
• Sealing and protection maintained to the factory standard
• One less known-weak point flying through your application window
• Confidence that the repair is done, not patched
• A maintenance log entry with a real DJI part number behind it
• Full compatibility with the parts around it — because it is the part the diagram calls for

Stock the spinner disk before the season does its work, and the spinner disk assembly never becomes the reason the aircraft sits.

Diagnose a spinner disk in the field before you diagnose it on the bench, because the spread pattern tells you more than the part does. Lay collection trays or shallow pans in a line across the swath, fly a single pass at your normal height and rate, and weigh or eyeball what lands in each one. A worn or damaged disk almost never simply spreads less. It spreads unevenly, throwing heavy to one side and starving the other, and the field shows it as stripes weeks later.

Check the disk for runout before you condemn anything else in the spreading system. With the aircraft safe and power off, refit the disk on its drive and turn it slowly by hand while you sight across the rim against a fixed reference such as the edge of the hopper outlet or a ruler clamped nearby. A disk that rises and falls or moves in and out as it turns is either bent, cracked at the hub, or sitting on a drive that is no longer true. Any of those throws material in a pattern that changes every revolution.

Compare the vanes against each other rather than against a number nobody published. Take the disk off, clean it, and look at each vane in turn: the leading edge, the outer tip, and the root where it meets the disk face. Granular fertilizer is abrasive, and it wears the trailing face of every vane at roughly the same rate until something changes. When one vane is visibly shorter, thinner, or more rounded at the tip than its neighbors, the disk is no longer throwing a symmetric pattern.

Balance is worth checking by hand and costs nothing. Off the aircraft, support the disk on a smooth round bar or a bolt through its center bore and let it settle. A disk that comes to rest in the same position every time you spin it has a heavy side, which after a season usually means dried product packed into one region, a cracked vane, or metal lost from one tip. Clean it and repeat. If it still settles the same way when clean, it is not balanced and it will shake the spinner drive every time it runs.

Separate a disk fault from a metering fault before ordering. The spinner throws what the metering system gives it, so a low rate, a surging rate, or nothing at all coming out is a hopper, gate, or auger problem rather than a disk problem. Run the system with the disk removed and confirm material falls freely and steadily from the outlet. If the flow is wrong with the disk out of the picture, a new disk changes nothing except your parts bill.

Rule the drive in or out before you blame the disk. With the disk removed, take hold of the spinner drive shaft or hub and try to move it side to side and in and out. It should turn smoothly with no rocking and no gritty feel. Play or roughness there is a bearing or a motor problem, and it will destroy a new disk as fast as it destroyed the old one because the disk cannot run true on a hub that does not run true.

Look at the hub bore and the drive features on the disk with more care than you look at the vanes. This is where torque enters the part, so this is where a disk that has been run loose shows it first: a bore gone oval, a drive slot or flat rounded off, witness marks that show the disk has been turning on its drive rather than with it. A disk that has been slipping will feel fine in your hands and still fail within hours of going back on.

Read cracks in the right order. Wash and dry the disk, then flex it gently and look at the underside with a strong light held low across the surface. Cracks in a spinner disk start where load concentrates: at the hub, at the root of a vane, and at any fastener or rivet location. A crack you can only see under flex is still a crack, and on a part that spins under a hopper full of product it is not something to watch through the rest of a season.

⚙️ Functional Purpose

The spinner disk is designed to do one job in the spinner disk assembly and do it to specification: metering and throwing granular material in a controlled swath.

The component:

• Serves the spinner disk assembly of the DJI Agras T100 exactly as the factory intends
• Supports metering and throwing granular material in a controlled swath
• Maintains the tolerances and interfaces the surrounding parts depend on
• Withstands the chemical, vibration, and washdown environment of agricultural work
• Preserves the sealing and protection strategy of the platform
• Keeps failure modes visible and diagnosable instead of mysterious
• Restores factory behavior immediately upon correct installation
• Protects the more expensive components it works alongside
• Carries the exact DJI specification for its position
• Supports safe, predictable operation under full payload
• Eliminates the guesswork of near-fit substitutes
• Keeps the aircraft inside its designed maintenance program
• Holds up across a full season of professional duty

Function on the T100 is a chain: spreading system performance depends on the spinner disk assembly, and the spinner disk assembly depends on every part in it holding specification. This component is one link in that chain — and chains fail at the worn link, not the average one.

That is why the platform's maintenance philosophy is inspection and renewal, not run-to-failure. The operators with the best uptime records are not the ones with the newest aircraft — they are the ones who replace parts like this when inspection says so, on their own schedule instead of the failure's.

A failing spinner disk costs you:

• Downtime in the middle of an application window — the most expensive hours in agriculture
• Acres not covered while the aircraft waits on a part
• Collateral wear on the components around the failing one
• Diagnostic hours chasing symptoms instead of causes
• Rework when a temporary fix lets go mid-job
• Customer trust when scheduled work slips
• Higher repair bills the longer the fault runs
• Risk exposure every flight the fault remains aboard
• Resale value on an airframe with deferred maintenance

Fix it on your schedule, not the failure's.

Make the spreading system safe before your hands go near the disk. Power the aircraft down and disconnect the flight batteries, because a spinner that starts while a hand is on it does real damage. Empty the hopper or at least close and confirm the gate, and be aware that granular product left in the hopper will pour out the moment the disk and outlet are disturbed. Work on a level surface with the aircraft supported so nothing shifts as you take weight off one side.

Clean the area before anything is loosened. Granular product packs hard around a spinner hub, into the drive features, and around the retaining hardware, and every bit of it turns into grit in a thread or a bore as soon as you start turning fasteners. Brush and rinse the disk, the hub, and the retainer, then dry them. Dried fertilizer is also corrosive to whatever it is sitting against, so what you find under the cake matters more than the cake itself.

Photograph the assembly before it comes apart, including which way the vanes face. Spinner disks are directional. The vanes throw material only when the disk turns the way its vanes are shaped for, and a disk fitted upside down or a handed disk fitted on the wrong side will still bolt on, still spin, and still spread, just badly and in the wrong pattern. A photo of the disk in place, with the drive visible, settles the argument later in about two seconds.

Release the retaining hardware in the order the design intends. This position is listed on the official parts breakdown alongside a thumb nut and an R type pin, which is hardware meant to be removed by hand rather than driven with a tool. Take the pin out first and keep it, because an R type pin is the single easiest thing on a spreader to lose in stubble, and a spinner disk retained by a nut with no secondary retention is a disk that will eventually leave the aircraft in flight.

Lift the disk straight off the drive rather than levering it. If it is stuck, the cause is dried product or corrosion in the bore, not an interference fit, so soak it with water and work it rather than prying under the rim. A screwdriver under a spinner disk bends the outer edge, and a bent rim is precisely the fault that puts the pattern out. Support the weight as it comes free so the disk does not drop onto the drive splines or the outlet.

Inspect the drive and the hub while the disk is off, because this is your only view of it. Turn the drive by hand and feel for roughness, rocking, or endfloat. Look at the drive features for rounding or wear, at the shaft for scoring, and at the seal or shield below it for product that has worked past. Check that no granular material has packed into the drive itself, since product in there acts as an abrasive and grinds the drive features away every hour the system runs.

Clean the mating faces before the new disk goes on. Anything trapped between the disk and its drive holds the part off square, and a spinner disk that sits even slightly cocked runs out at the rim far more than the error at the center, which is what turns a small assembly mistake into a visible pattern fault. Wipe both faces dry, confirm nothing is raised or burred, and offer the new disk up dry to check it drops onto the drive fully and squarely.

Fit the disk the way it came off, and confirm the direction. Line the drive features up rather than forcing them, seat the disk fully so there is no gap under the hub, and check that the vanes present themselves the same way the photograph shows. If your system runs more than one spinner, confirm each disk goes back to the side it came from before you retain anything, since disks intended for opposite sides are mirror images and are easy to swap in a hurry.

Retain it properly and treat the R type pin as a required part rather than an option. Run the thumb nut down by hand until the disk is firmly held with no rock at the rim, then fit the pin through the hole it belongs in and confirm the leg has sprung fully home over the shaft. Where DJI publishes a torque figure for hardware at this position, use it with a calibrated driver. A spinner disk that is retained by friction alone will find its way loose under vibration.

Check by hand before you check with power. Turn the disk through several full revolutions by hand and watch the rim against a fixed reference for wobble, listen and feel for anything touching, and confirm there is clearance all the way around between the vanes and the outlet, the shroud, and any structure nearby. Then grip the rim and try to rock it. Nothing should move. This ten second check catches almost every fitting error before it becomes an in flight one.

Verify with the system running before you verify with product in the hopper. Power up and run the spreading system on the ground with the hopper empty, listening for a new vibration, a rub, or a change in the note the spinner makes as it comes up to speed. Then load a small quantity, run a short calibration or test pass, and check the pattern with trays across the swath. Confirm the aircraft reports no spreading system faults, and recheck the retaining hardware after the first working day.

⚠️ Common Replacement Indicators

• Visible cracking, deformation, or impact damage
• Stress-whitening at load points
• Loose fit where the part should seat firmly
• Movement or rattle the design does not allow
• Wear marks from parts contacting where they should not
• Fastener holes elongated or damaged
• Chemical or UV degradation of the material
• Damage found during teardown of the assembly
• Misalignment of the components this part positions
• Noise or vibration traced to this position
• Damage after a hard landing or transport strike
• Previous field repair with tape, glue, or improvisation

What kills structural and mounting parts: the compounding of ordinary duty. Chemical exposure attacks materials, vibration works at every interface, UV ages every exposed surface, and washdowns drive water at every seam — repeated across hundreds of cycles per season. Add the occasional hard landing or transport knock and the result is predictable: the part that was fine in spring is the failure point by late season.

Replacement and verification: Replacement is a standard shop task on the T100: open access to the spinner disk assembly, document connections and hardware positions, swap the spinner disk for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work.

Confirm before you order: this is DJI part YC.JG.ZS006256. Check the label on your old spinner disk or the position in your official parts diagram and match the number — revision suffixes like .01 or .F on a label are the same part.

Striping in the crop, running the same direction as your passes, is the classic spinner disk complaint and it usually shows up two to three weeks after the application rather than on the day. Heavy stripes where passes overlapped and pale stripes between them mean the disk is no longer throwing to the edges of its swath. Worn vane tips are the most common reason, since the tip is where the granule leaves the disk and where abrasion takes the most material.

A pattern that is heavy on one side of the aircraft and thin on the other points at something asymmetric on the disk itself. One vane worn shorter than the rest, one vane cracked at its root, a bent section of rim, or dried product packed against one part of the disk face will all bias where material goes. This is worth checking with trays rather than by eye, because a pattern can be badly one sided while the total rate coming out still looks correct.

New vibration that appears only when the spinner is running, and disappears when it stops, is an out of balance disk until proven otherwise. The usual causes are product caked into one region, a lost vane tip, a crack, or a disk that is not seated squarely on its drive. It is not a symptom to live with, because that imbalance is being fed straight into the spinner drive and its bearings for every minute the system runs.

A rhythmic scraping, ticking, or rubbing that keeps time with the disk means something is touching once per revolution. Either the disk is running out because it is bent, cracked at the hub, or not seated, or something has moved into its path. Stop and find it. A vane clipping a shroud or an outlet edge will wear the vane away in a fraction of a season and destroy whatever it is hitting at the same time.

Granules dropping more or less straight down beneath the aircraft, with a swath much narrower than you are used to, means the disk is not accelerating the material the way it should. Badly worn or broken vanes are the usual cause, since a disk with short vanes releases the granule before it has picked up speed. A disk turning slower than commanded is the other possibility, which takes you to the spinner drive rather than to the disk.

A spinner that is slow to come up to speed, that bogs when material starts flowing, or that trips a fault under load is not necessarily a motor problem. A disk that is packed with dried product weighs considerably more than a clean one and takes more torque to spin, and a disk fouling on structure adds drag that looks identical to a failing drive. Clean it and check clearance before you condemn anything electrical.

Play at the rim that you can feel by hand, or a disk you can rock on its drive, means the retention has let go or the hub bore and drive features have worn. Either way the disk is now transmitting torque through impact rather than through a fit, which chews the drive and the bore at an accelerating rate. Once you can feel it in your hand, it has been happening for a while and the drive needs inspecting as carefully as the disk.

Missing hardware is a stop right there. If the R type pin is gone, or the thumb nut is finger loose when you check it, the disk has been relying on nothing but friction and it was going to come off. Find out why: a worn pin hole, a distorted pin that no longer springs home, or a nut that has lost its bite. Fitting a new disk without fixing the retention just puts a better part in the same danger.

White or crusty deposits, pitting, or a surface that has gone rough and dull tell you fertilizer salts have been sitting on the disk between jobs. Urea and ammonium based products draw moisture out of the air and attack what they lie against, and the roughened surface that results is not just cosmetic. A rough disk face and rough vanes change how granules slide and release, and pitting gives cracks somewhere convenient to start.

Construction: DJI OEM molded or machined component manufactured to factory dimensions

Application: DJI Agras T100 spreading system service and repair

Condition: Brand new

Disk Diameter, Vane Count, and Weight: Not published in this listing. Count the vanes and compare the profile against the disk you removed rather than working from a remembered figure, and confirm the part by DJI material number YC.JG.ZS006256 against the label on the old disk or the callout on the official DJI Agras T100 parts breakdown.

Material and Corrosion Rating: Not stated by the supplier. No material grade or corrosion specification is published for this disk, so treat it as vulnerable to fertilizer salts and rinse it after every job rather than assuming it will shrug off urea or ammonium sulfate residue left on it overnight.

Spinner Speed, Swath Width, and Spread Rate: Not published here. Swath and rate on a spreading system depend on the disk, the material, the gate setting, the flight height, and the speed you are flying, so use your own tray test and the calibration procedure in the DJI documentation rather than any figure quoted for another machine or another product.

Retaining Hardware Torque: Not published in this listing. The official parts breakdown lists a thumb nut and an R type pin at this position, which are hand fitted rather than driven to a torque figure. Where DJI publishes a value for any threaded hardware here, use it with a calibrated driver, and always fit the secondary retention rather than relying on the nut alone.

Retaining Hardware Included: Read the Package Includes list on this listing, which is the authority on what actually ships. The thumb nut, the R type pin, and the screw callout that appear alongside this part on the breakdown are separate components with their own DJI material numbers, and a worn or distorted pin should be replaced rather than reused.

Handedness and Rotation Direction: Not specified in this listing. Spinner disks are directional, so establish orientation from the disk you removed and from photographs taken before disassembly rather than from the product image. If your spreading system runs more than one spinner, confirm each disk returns to the side it came from.

Service Classification: Wear part, replaced on condition rather than at any published interval. The conditions are vane tips worn or broken, uneven wear between vanes, cracking at the hub or a vane root, a bent or distorted rim, a hub bore or drive feature that has rounded off, and a pattern fault that survives cleaning and recalibration.

• Pre-contract equipment checks before custom application work
• Mid-season turnarounds where the machine has to fly tomorrow

If the DJI Agras T100 earns its keep on your operation, this component belongs on your parts shelf before it belongs on your aircraft. The time to buy it is before the season, not during the failure.

The confusion that costs operators the most on a spreading system is between the spinner disk itself and the complete spinner disk assembly. This listing supplies the disk that carries the vanes and throws the material, DJI material number YC.JG.ZS006256. The assembly around it includes the drive and its mounting, and it carries a different number. If your fault is roughness, rocking, or noise in the drive, a bare disk will not fix it, and if your fault is a worn vane, you do not need the assembly.

If your spreading system runs more than one spinner, do not assume the disks are interchangeable between positions. Disks intended for opposite sides are mirror images of each other, and both will fit, spin, and throw material. What changes is where the material goes, and the resulting pattern fault is subtle enough that operators chase it through gate settings and flight height for weeks before anyone thinks to look at which disk went where.

Do not confuse the spinner disk with the impeller, agitator, or metering hardware inside the hopper outlet. Those parts control how much material arrives at the disk, and this part controls where it goes once it gets there. A rate complaint belongs to the metering side of the system, and a pattern complaint belongs to the disk. Getting that backwards means ordering the right part for the wrong symptom and still having the problem after the repair.

Spinner disks across DJI Agras spreading systems look very much alike in a photograph and are described in almost identical words, so a disk pulled out of a parts bin without a legible label is not identifiable by eye. Compare it against the part you removed feature by feature: the hub bore and drive features, the number and shape of the vanes, the rim profile, and the retaining hardware hole. Anything that differs is a reason to stop rather than to fit it and see.

Watch the model line as carefully as the part name. Confirm the aircraft is a DJI Agras T100 and confirm the base number YC.JG.ZS006256 on the label of the disk you removed or the callout on the official parts breakdown. A revision suffix such as .01 or .F printed on a label is the same part. A disk from a different Agras spreading system will bolt up close enough to be tempting, and it will not throw the pattern the machine was calibrated for.

Keep the retaining hardware straight as well. The breakdown lists a thumb nut, an R type pin, and a screw callout at this position, and none of those is a place for a substitute from the shop drawer. An R type pin whose legs have been sprung open no longer retains anything reliably, and a hardware store nut with no secondary retention is how spinner disks depart in flight. Replace worn retention with the callout rather than with whatever fits the thread.

💡 Why This Part Matters

Every acre the T100 covers depends on the spinner disk assembly doing its job — and the spinner disk assembly depends on parts exactly like this one.

The economics are simple. The DJI Agras T100 exists to cover ground during windows that do not wait — and every hour it sits, the work either doesn't happen or happens on someone else's schedule. A failed spinner disk is rarely expensive because of what the part costs; it is expensive because of when it fails. Parts fail during use, and use happens during the season.

That is the case for OEM and the case for stocking ahead. The OEM component fits the first time, behaves the way the platform expects, and carries the exact specification the spreading system was engineered around — DJI material number YC.JG.ZS006256. No adaptation, no surprises, no second teardown to undo a near-fit part.

This component delivers:

• Factory-correct fit in the spinner disk assembly — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored function you can verify on the first post-repair check
• Sealing and protection maintained to the factory standard
• One less known-weak point flying through your application window
• Confidence that the repair is done, not patched
• A maintenance log entry with a real DJI part number behind it
• Full compatibility with the parts around it — because it is the part the diagram calls for

Running a compromised spinner disk, operators risk:

• Mid-job failure during an application window
• Collateral damage to surrounding components
• Progressive damage that turns a cheap fix into an expensive one
• Alignment and fit problems spreading to adjacent parts
• Unplanned grounding with the fleet committed to jobs
• Warranty and service complications from improvised fixes
• Higher lifetime cost from deferred maintenance
• An aircraft that cannot be trusted at full payload

Inspect it honestly. Replace it once. Fit it right. Keep it flying.

Ares Acres stocks the spinner disk in the USA with free, fast shipping — so the day you need one is the day it ships, not the week you wait.

While the disk is off, give the spinner drive the attention it will never get again this season. Turn it by hand and feel for roughness or rocking, look at the drive features for rounding, and check for granular product packed into the drive where it acts as a grinding paste. A disk that has been running out of balance has been feeding that imbalance into the drive bearings the whole time, so a disk failure is a reason to inspect the drive rather than to ignore it.

Inspect the retention every single time. Check that the R type pin still springs home firmly and that its legs have not been sprung open by repeated removal, that the pin hole in the shaft is round rather than elongated, and that the thumb nut still bites cleanly along the whole thread. Retention hardware is the cheapest thing on the aircraft and the most expensive thing to be missing, because what it prevents is a spinning disk leaving the aircraft over a field.

Look over everything the disk throws material past. The hopper outlet, the gate, any shroud or deflector, and the structure around the spinner all take a constant blast of abrasive granules, and they wear. A groove worn into an outlet edge or a deflector that has thinned changes the pattern just as surely as a worn vane, and it is worth finding while the disk is off and the area is actually visible.

If the disk was damaged by an impact rather than by wear, widen the inspection before the aircraft flies. Something hard enough to bend a spinning disk reached that area at speed, so check the drive shaft for a bend, the mounting for cracks, and any nearby structure and cabling for damage. A bent disk on an undamaged drive is unusual, and fitting a new disk to a drive that took the same hit gets you a second new disk in short order.

What retires a spinner disk in normal service is abrasion, and abrasion is unavoidable because throwing granules is the job. Vane tips wear first and fastest since that is where the granule is moving quickest relative to the metal, then the trailing faces of the vanes, then the disk face itself. Nothing about that process is a defect. What matters is catching it before the wear goes asymmetric, because an evenly worn disk spreads a little narrow and an unevenly worn disk spreads badly.

Fertilizer chemistry is the other half of the life equation and it works on the disk between jobs rather than during them. Urea and ammonium based products pull moisture out of the air, so a film of dust left on a disk overnight turns into a wet, aggressive layer sitting against the surface for hours. Rinse the spinner and the outlet with clean water at the end of every spreading day, then let it dry rather than closing it up wet.

Never fly a disk you have repaired. Welding, brazing, or bonding a vane back onto a part that spins at working speed under a hopper of product puts a hard, brittle line exactly where the load is highest, and when it lets go it does so at full speed with the aircraft in the air. The same applies to straightening a bent rim: the metal has already yielded once and it will yield again in the same place, only now with a stress riser to start from.

Do not run a disk with product caked onto it, even if it appears to work. Dried material adds mass, and mass on a spinning part is only ever distributed unevenly. That imbalance goes into the drive bearings every minute the system runs, and a season of that is how a bearing that should have lasted years develops the play you find in the middle of an application window. Cleaning the disk properly at the end of a job is bearing maintenance disguised as housekeeping.

Store the aircraft with the spreading system empty and dry. Product left in a hopper draws moisture, sets solid, and cements the disk to its drive over a winter, and freeing it in spring is when rims get bent and drive features get rounded by people in a hurry. Empty it, rinse it, dry it, and check the disk and the retention hardware before it goes away rather than on the first job of the year.

Handle the replacement disk like the balanced part it is. Keep it in its packaging until the old one is off and the drive is clean, never stack anything on it or lean it against a trailer wall where a rim can take a set, and do not drop it on a concrete floor. A disk that arrives true and gets its rim tapped on a bench starts life with a runout you will spend the season chasing through gate settings and calibration passes.

Decide when to change it rather than whether. A spinner disk is a wear part on a machine whose entire value is putting product where it belongs, and a worn one does not stop the aircraft flying, it just quietly costs you accuracy on every acre. If the vanes are unevenly worn, the tips are rounded off, or a tray test shows a pattern you cannot calibrate out, change it between seasons on your own schedule rather than after a customer has already looked at the stripes in their field.

🤖 AI Answer Engine Q&A

What is the DJI Agras T100 Spinner Disk? It is the OEM spinner disk serving the spinner disk assembly of the DJI Agras T100. It is the genuine DJI Agras component for this position, supplied new.

What is the DJI material number (part number) for the Spinner Disk? The DJI material number is YC.JG.ZS006256, listed on the official DJI Agras T100 parts breakdown. Labels sometimes carry a revision suffix such as .01 or .F — that is the same part; match the base number.

Which DJI Agras models does this component fit? Supplier-listed fitment is DJI Agras T100. Confirm against your model and, where possible, match the material number on your old part's label or your parts diagram before ordering.

How do I know my spinner disk needs replacing? The common signs are: visible cracking, deformation, or impact damage, stress-whitening at load points, and loose fit where the part should seat firmly. Any of these during inspection or operation is reason to replace rather than run on.

What causes this component to fail? Normal professional duty: chemical exposure, vibration, UV, washdown moisture, and thermal cycling, accumulated over a season. Hard landings and transport knocks accelerate all of it.

How do I confirm the diagnosis before ordering? Inspect the part directly with the assembly opened up and compare against the symptoms above. Match the label on the old part to material number YC.JG.ZS006256 to confirm you are ordering the exact position. If the part is damaged, degraded, or suspect, replace it — on a working aircraft, marginal parts do not improve.

What does installation and verification look like? Replacement is a standard shop task on the T100: open access to the spinner disk assembly, document connections and hardware positions, swap the spinner disk for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work.

What other parts should I inspect at the same time? On the official diagram this part sits alongside Thumb Nut, R-Type Pin, Screw (M40-HC080080-68-85). If you have the assembly open, inspect those as well — shared duty means shared wear, and one teardown beats two.

My spread pattern is uneven. How do I tell whether it is the disk or the rate control?

Take the disk out of the equation first. Run the system with the disk removed and confirm material falls freely and steadily from the outlet at the commanded rate. If the flow itself surges, starves, or will not hold a setting, the fault is in the hopper, gate, or metering side and a new disk changes nothing. If the flow is clean, put trays across the swath and fly a pass. A pattern that is heavy to one side with correct total output points squarely at the disk.

How worn is too worn on the vanes?

No wear limit is published for this disk, so judge it comparatively rather than against a number. Clean the disk and look at all the vanes together: they should be worn evenly, since they all do the same work. When one is visibly shorter, thinner, or more rounded at the tip than its neighbors, the disk is throwing asymmetrically. Tips that have gone round rather than square across the whole disk mean it is spreading narrow, which a tray test will confirm.

Do I really need the R type pin, or is the thumb nut enough?

Fit the pin. A thumb nut on a part that spins under vibration is a primary retainer, not a complete retention system, and the pin is what keeps the disk on the aircraft when the nut works loose. Check that the legs still spring fully home over the shaft and that the hole they pass through is round rather than elongated. A pin that has been sprung open by repeated removals should be replaced rather than persuaded back into shape.

Is this the disk only, or the whole spinner assembly?

This listing supplies the spinner disk, DJI material number YC.JG.ZS006256. The drive and its mounting are separate components with their own numbers. That distinction matters when you are diagnosing: worn vanes, a bent rim, or a cracked hub is a disk problem, and roughness, rocking, endfloat, or noise you can feel in the drive with the disk removed is not something a new disk will improve.

Can I straighten a bent rim or weld a broken vane?

No. This part spins at working speed under a hopper of product, and a repair line is a brittle stress concentration in the worst possible location. Metal that has already yielded once yields again in the same place, and a vane that lets go in flight does so at full speed. It is also nearly impossible to rebalance a repaired disk by eye, and an out of balance disk feeds that imbalance straight into the spinner drive bearings.

The spinner shakes when it runs but the disk looks fine. What now?

Clean it properly first, because product caked into one region of a disk is the most common cause of imbalance and it hides under a film of dust. Then support the disk on a bar through its center bore and see whether it settles to the same position every time. If it does, it is out of balance. If it is genuinely clean and balanced, check that it is seated fully and squarely on its drive, then check the drive itself for play with the disk removed.

What is the right way to clean it after spreading fertilizer?

Rinse the disk, the hub, the outlet, and the surrounding area with clean water at the end of every spreading day, then let everything dry before the aircraft is put away. Urea and ammonium based products draw moisture from the air, so a dry film left overnight becomes a wet, aggressive layer sitting against the metal for hours. Keep aggressive cleaners away from it and use water and mild detergent for anything a brush will not shift.

Does the disk have to go on a particular way round?

Yes. Spinner disks are directional, and the vanes only throw properly when the disk turns the way they are shaped for. A disk fitted the wrong way up, or a handed disk fitted on the wrong side of a system that runs more than one, will still bolt on and still spin, and it will spread badly in a way that is hard to trace. Photograph the disk in place before removal and use the photograph rather than your memory when it goes back.

Do I need to recalibrate the spreading system after fitting a new disk?

Run the calibration procedure DJI publishes for your spreading system, and then confirm it with your own tray test using the product you actually apply. A new disk has full length vanes and a clean face, so it will throw a wider and more even pattern than the worn one you took off, which means the settings you had dialed in for the old disk were compensating for wear that no longer exists.

The disk is stuck on the drive and will not come off. What should I do?

Do not lever under the rim. It is stuck because dried product or corrosion has bonded the bore to the shaft, not because of an interference fit, so soak it with clean water, give it time, and work it back and forth by hand. A screwdriver under the edge bends the rim, and a bent rim is exactly the fault that ruins a pattern, so you would be creating the problem you are trying to fix while removing a part you may not have needed to replace.

Can I keep using a disk with a small crack until the end of the season?

No. A crack in a spinning disk grows with every revolution, and this part turns under the load of material being flung off it while the aircraft is in the air. Cracks in a spinner disk start where load concentrates, at the hub, at a vane root, or at a hardware hole, and those are the locations least able to tolerate a defect. If you found a crack under flex with a light behind it, it is real and the disk is finished.
