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.

It transmits torque from the spreader drive to the disk, and it locates that disk squarely and concentrically so the granules leave in the pattern the swath was set up around. Torque wear shows up at the drive feature, where the disk grips the shaft. Location wear shows up at the seating shoulder and at the retention. A shaft can be perfectly sound in one of those roles and finished in the other.\u003c\/p\u003e\n\u003cp\u003eThe thing that makes this part unusual in the catalogue is how often it gets handled. The disk comes off with a Thumb Nut and an R-Type Pin, which is a deliberately tool-free arrangement because a spreader has to be opened and washed out constantly. That convenience puts the thread and the pin hole through a cycle every single time the machine is cleaned, and those two features carry all of the retention. They see more use than the shaft's rotating duty ever will.\u003c\/p\u003e\n\u003cp\u003eThen there is what the shaft sits in. Granular fertilizer is abrasive going through and corrosive once it gets wet, and a spreader that has been rinsed and put away damp holds a paste of product in exactly the places you cannot see: down in the threads, inside the pin hole, and under the disk hub. Steel parts that live in dry conditions last a long time. The same parts living under fertilizer residue do not, and the damage starts in the threads rather than on the visible surfaces.\u003c\/p\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\u003cp\u003eThe spinner disk shaft 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe component:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eServes the spinner disk assembly of the DJI Agras T100 exactly as the factory intends\u003c\/li\u003e\n\u003cli\u003eSupports metering and throwing granular material in a controlled swath\u003c\/li\u003e\n\u003cli\u003eMaintains the tolerances and interfaces the surrounding parts depend on\u003c\/li\u003e\n\u003cli\u003eWithstands the chemical, vibration, and washdown environment of agricultural work\u003c\/li\u003e\n\u003cli\u003ePreserves the sealing and protection strategy of the platform\u003c\/li\u003e\n\u003cli\u003eKeeps failure modes visible and diagnosable instead of mysterious\u003c\/li\u003e\n\u003cli\u003eRestores factory behavior immediately upon correct installation\u003c\/li\u003e\n\u003cli\u003eProtects the more expensive components it works alongside\u003c\/li\u003e\n\u003cli\u003eCarries the exact DJI specification for its position\u003c\/li\u003e\n\u003cli\u003eSupports safe, predictable operation under full payload\u003c\/li\u003e\n\u003cli\u003eEliminates the guesswork of near-fit substitutes\u003c\/li\u003e\n\u003cli\u003eKeeps the aircraft inside its designed maintenance program\u003c\/li\u003e\n\u003cli\u003eHolds up across a full season of professional duty\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eFunction 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.\u003c\/p\u003e\u003cp\u003eThat is why the platform's maintenance philosophy is inspection and renewal, not run-to-failure.

A spinner disk throws product by flinging it off a rotating surface, so the pattern the aircraft was calibrated to depends on the disk turning about its true center in a plane the design expects. A shaft that has bent, that seats a disk at an angle, or that lets the disk sit slightly off center turns a symmetrical pattern into a lopsided one. Nothing in the software knows that has happened, so the swath quietly goes wrong while every setting still reads correct.\u003c\/p\u003e\n\u003cp\u003eThe second function is holding the disk on. That sounds too obvious to state until you consider what the failure looks like: a disk leaving a shaft at working speed on a machine flying over a field. The Thumb Nut carries the clamp and the R-Type Pin is the backstop that stops the nut walking off under vibration. The shaft supplies the thread and the hole those two rely on, which is why wear at either feature is a stop-work item rather than something to watch.\u003c\/p\u003e\n\u003cp\u003eThird, the shaft is what the drive torque actually passes through, and granular spreading is not a smooth load. Product arrives on the disk in surges as the gate opens and as the hopper level changes, so the shaft sees repeated torque pulses rather than steady drive. Those pulses are what round out a worn drive feature, and once the disk can move even slightly against the shaft under load, the wear accelerates because every pulse now lands on a smaller contact area.\u003c\/p\u003e\n\u003ch2\u003e⚠️ Common Replacement Indicators\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eVisible cracking, deformation, or impact damage\u003c\/li\u003e\n\u003cli\u003eStress-whitening at load points\u003c\/li\u003e\n\u003cli\u003eLoose fit where the part should seat firmly\u003c\/li\u003e\n\u003cli\u003eMovement or rattle the design does not allow\u003c\/li\u003e\n\u003cli\u003eWear marks from parts contacting where they should not\u003c\/li\u003e\n\u003cli\u003eFastener holes elongated or damaged\u003c\/li\u003e\n\u003cli\u003eChemical or UV degradation of the material\u003c\/li\u003e\n\u003cli\u003eDamage found during teardown of the assembly\u003c\/li\u003e\n\u003cli\u003eMisalignment of the components this part positions\u003c\/li\u003e\n\u003cli\u003eNoise or vibration traced to this position\u003c\/li\u003e\n\u003cli\u003eDamage after a hard landing or transport strike\u003c\/li\u003e\n\u003cli\u003ePrevious field repair with tape, glue, or improvisation\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat 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.\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eReplacement and verification:\u003c\/strong\u003e 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 shaft 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eConfirm before you order:\u003c\/strong\u003e this is DJI part YC.JG.QX004442. Check the label on your old spinner disk shaft 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.\u003c\/p\u003e\u003cp\u003eThe disk visibly wobbles or the assembly rattles when you turn it by hand. With the machine shut down, fit the disk and spin it slowly while watching its rim against a fixed point on the housing. A disk that rises and falls or moves in and out as it turns is running out of true. Swap in a known-good disk and repeat the check: if the wobble follows the disk it is the disk, and if it stays behind it is the shaft or what the shaft is mounted in.\u003c\/p\u003e\n\u003cp\u003eThe thumb nut will not run down cleanly by hand. A thumb nut is a hand-tightened fastener by design, so if yours needs pliers, needs to be started three times, or feels gritty going on, the problem is the thread and not your grip. Look for a flattened, corroded, or bruised thread start on the shaft. Forcing a nut onto a damaged thread is how a shaft that needed cleaning becomes a shaft that needs replacing.\u003c\/p\u003e\n\u003cp\u003eThe R-pin hole is elongated, belled, or has a lip worn on one side. That hole is what stops the nut from backing off, and once it has gone oval the pin can walk under vibration. Look at it from both sides with the pin out, because wear is often obvious from one face and invisible from the other. An oval pin hole on a rotating retention is not something to run to the end of the season.\u003c\/p\u003e\n\u003cp\u003eThe spread pattern has shifted to one side and the gate and rate settings check out. Before you chase the metering, look at what the disk is turning on. A shaft with a set in it, a damaged seating shoulder, or product packed under the disk hub will present the disk at an angle, and an angled disk throws long on one side and short on the other. It is a mechanical fault that looks exactly like a calibration fault.\u003c\/p\u003e\n\u003cp\u003eThe disk slips or clicks against the shaft when the load comes on. This is drive-feature wear, and you can usually feel it by hand: hold the shaft, grip the disk, and try to rotate one against the other. Any perceptible movement means the torque path has worn, and the symptom under load is intermittent throw as the disk momentarily lags and catches up. It gets worse quickly once it starts.\u003c\/p\u003e\n\u003cp\u003eRust bloom, packed product, or a chalky white deposit around the threads and under the disk hub. Fertilizer residue holding moisture against metal is the most reliable way to retire this part early, and the corrosion works from inside the features you cannot inspect without disassembly. Finding this at teardown is a reason to look hard at the thread and pin hole rather than to clean it off and reassemble.\u003c\/p\u003e\n\u003ch2\u003e📐 Specifications\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eDJI Material Number:\u003c\/strong\u003e YC.JG.QX004442\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePart:\u003c\/strong\u003e Spinner Disk Shaft\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eType:\u003c\/strong\u003e OEM structural \/ mounting component\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCompatibility:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eDJI Agras T100\u003c\/li\u003e\n\u003cli\u003ePosition: the spinner disk assembly\u003c\/li\u003e\n\u003cli\u003eDiagram sheet: Spinner Disk Assembly (official T100 parts list)\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInstallation Area:\u003c\/strong\u003e The spinner disk assembly\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFunction:\u003c\/strong\u003e Metering and throwing granular material in a controlled swath\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eConstruction:\u003c\/strong\u003e DJI OEM molded or machined component manufactured to factory dimensions\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eApplication:\u003c\/strong\u003e DJI Agras T100 spreading system service and repair\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Brand new\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eShaft dimensions, thread, and material:\u003c\/strong\u003e Length, diameter, thread size and pitch, drive-feature geometry, and the material and any surface treatment are not published in the DJI parts breakdown and are not carried in this listing.

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 shaft 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.\u003c\/p\u003e\u003cp\u003eThat is the case for OEM and the case for stocking ahead.

Pull the R-Type Pin, back the Thumb Nut off by hand, lift the disk straight up rather than rocking it off, and note which face of the disk was outward before it leaves the bench. The shaft itself may be retained to the drive by a fastener or a clamping feature, so look before you pull. Do not hammer a stuck shaft, do not lever against the spinner housing, and do not use the disk as a handle to twist the shaft free.\u003c\/p\u003e\n\u003cp\u003eClean before you assess and assess before you order. Fertilizer residue hides exactly the damage you are looking for, so wash the shaft, dry it, and inspect the thread start, the full thread, the pin hole from both faces, the drive feature, and the seating shoulder under a strong light held at a low angle. A shaft that looks pitted through a film of dried product is often serviceable, and one that looks clean can have a belled pin hole you will only see once it is dry.\u003c\/p\u003e\n\u003cp\u003eOn refit, put the parts back dry and check the disk before the pin goes in. Make sure the seating face and the underside of the disk hub are clean, since a single packed granule under the hub will cock the disk and skew the pattern. Run the thumb nut down by hand, seat the disk, then spin it and watch the rim for runout before the R-pin goes home. Finding a problem now takes a minute; finding it as a pattern complaint takes a field.\u003c\/p\u003e\n\u003cp\u003eWhile it is apart, check the things the same wear cycle has been working on. Look at the Thumb Nut thread for stretch or damage, the R-Type Pin for a spread or softened leg that will not hold, the Spinner Disk for cracks radiating from its hub and for erosion on the throwing surfaces, and the drive it all mounts to for play or roughness when turned by hand. Play at the drive with the shaft removed is a bearing problem, and fitting a new shaft will not fix it.\u003c\/p\u003e\n\u003cp\u003eThe habits that kill these shafts are all end-of-day habits. Fertilizer left on the assembly overnight, a wash that soaks the threads without a dry afterwards, and storage in a damp shed do more damage than the spreading itself. Wash the assembly down after every spreading day, dry it properly, and store the aircraft with the residue gone rather than with it packed into the pin hole. If a shaft is being taken out of service for the winter, clean it, dry it, and look at it before it goes on the shelf rather than in the spring when you need it.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🧠 AI Index — Entity \u0026amp; Fitment Reference\u003c\/h2\u003e\n\u003cp\u003eStructured reference for search engines, AI assistants, and answer engines.

A granule or a crust of dried product trapped under the disk hub or on the seating shoulder tilts the disk a fraction of a degree, and a tilted disk throws long on one side and short on the other while every setting on the screen still reads correct. Take it apart, clean both faces, refit dry, and spin it by hand to check the rim runs true before you commit to a load.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe disk slips on the shaft under load. What is worn?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe drive feature, almost always, and by the time you can feel it the wear is well advanced. Hold the shaft, grip the disk, and try to twist one against the other: any perceptible movement is too much. Torque from a spreader arrives in surges as product feeds onto the disk, so once the contact area has rounded off, each surge lands on less metal and the wear accelerates. Inspect the disk hub at the same time, since both halves of a worn drive wear together.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I run the rest of the season on a shaft with an oval pin hole?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThat is the one wear item on this part that does not deserve a wait-and-see. The R-Type Pin is what keeps the thumb nut from backing off on a component spinning at working speed under an aircraft, and an elongated hole lets the pin move, wear the hole further, and eventually walk out. The failure that follows is a disk leaving the machine in flight. Replace the shaft, and fit a fresh pin with it rather than reusing the one that has been working in a loose hole.\u003c\/p\u003e\n","brand":"Ares Acres","offers":[{"title":"DJI T100","offer_id":53005110968640,"sku":"YC.JG.QX004442","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/0159\/0848\/files\/dji-agras-t100-spinner-disk-shaft-yc-jg-qx00-9392.png?v=1794510888","url":"https:\/\/aresacres.com\/pt\/products\/dji-agras-t100-oem-spinner-disk-shaft-yc-jg-qx004442","provider":"Ares Acres","version":"1.0","type":"link"}
