🔧 Component Overview

The DJI Agras T100 OEM Circlip is the OEM circlip in the mist spray lance of the DJI Agras T100, part of the structure carrying atomized spray hardware into the airflow beneath the rotors.

Carrying atomized spray hardware into the airflow beneath the rotors is the job description for the mist spray lance, 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 mist spray lance is sized, shaped, and specified around that duty. On the official parts diagram it sits alongside Mist Sprinkler Support Rod, Mist Spray Lance Connector, Centrifugal Sprinkler Adapter Cable (Optional).

Ignore a failing circlip 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 mist spray lance 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:

• Carrying atomized spray hardware into the airflow beneath the rotors
• 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 mist spray lance is opened up, and why operators who run hard keep spares on the shelf.

A healthy circlip delivers:

• Factory-correct fit in the mist spray lance — 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 circlip before the season does its work, and the mist spray lance never becomes the reason the aircraft sits.

A circlip rarely announces itself by breaking. What you find instead is movement in the part it was holding. With the lance supported and the assembly still together, try to move the retained component along its axis: a healthy retaining ring allows effectively no axial float, so anything you can feel by hand is a finding. A faint tick or click as the joint is rocked, felt more than heard, is the same fault caught at an earlier stage.

Once it is apart, judge the ring on whether it has taken a permanent set. Lay the removed clip on a flat surface: it should sit flat rather than dished or coned, and the gap between its ends should be close to what it was when new. A ring that has been opened past its elastic limit stays open, and it will not grip a groove again no matter how carefully it is fitted. Tool holes that have been spread, elongated, or torn are the same message arriving from a different direction.

Inspect the groove as carefully as the ring, because the groove is what actually does the holding. Run a fingernail or a fine scribe around it and feel for a rolled-over edge, a burnished shoulder, or a step where the ring has been hammering. A groove whose load-bearing wall has been worn round will let a brand-new clip climb out under vibration, and at that point the item that needs replacing is the component carrying the groove, not the clip.

Retaining rings that look interchangeable are not. Internal rings live in a bore and are squeezed to fit; external rings live on a shaft and are spread to fit, and their tool holes face the opposite way as a result. E-clips slide on from the side and have no tool holes at all. Beyond type, the free diameter, the section thickness, and the width of the ring all have to suit the groove it goes into. Set the new part on top of the one you removed and compare them directly before either goes near the lance, and confirm the base material number on the packaging.

⚙️ Functional Purpose

The circlip is designed to do one job in the mist spray lance and do it to specification: carrying atomized spray hardware into the airflow beneath the rotors.

The component:

• Serves the mist spray lance of the DJI Agras T100 exactly as the factory intends
• Supports carrying atomized spray hardware into the airflow beneath the rotors
• 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: atomized spray system performance depends on the mist spray lance, and the mist spray lance 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 circlip 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.

Eye protection is not optional on this job. A retaining ring stores energy the whole time it is spread or compressed, and a clip that slips off the pliers leaves at speed in a direction nobody predicts. Use circlip pliers with tips that actually fill the holes in the ring rather than a pair of picks or a screwdriver, keep a rag or a gloved hand loosely over the ring as it comes free, and position the assembly so that a launched clip lands somewhere you can find it again.

Open the ring only as far as it takes to clear the groove. Every degree past that is permanent damage you are building into a part you may still want for a test fit, and it is also how tool holes get elongated and how a ring ends up coned. Bring it off square rather than dragging one side out first, and support the component it was retaining so that nothing shifts the moment its axial location disappears.

Before the new ring goes on, clean the groove properly. Residue, dried spray concentrate, and corrosion product all pack into the corners of a groove and stop a ring from bottoming, and a ring sitting proud on packed debris is a ring that is only half in. Pick the groove out, flush it, dry it, and check with a light that you can see clean metal the whole way round. Then confirm the retained component is fully home first, because a clip is never a tool for pulling a part into position.

Fit the ring square and confirm it has bottomed all the way round rather than at the one spot you happened to be watching. Run a fingernail or a scribe around the full circumference and feel for any section standing proud; a ring that is home sits flat against the groove face with no visible gap and cannot be rocked. If the ring is stamped, with one sharp edge and one slightly rounded edge, the sharp side faces the load. With the joint back together, check for axial play by hand again: there should be none you can feel.

⚠️ 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 mist spray lance, document connections and hardware positions, swap the circlip 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.BJ003348. Check the label on your old circlip 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.

Detectable end float or wobble in the component the ring retains, where there was none before. That is the primary symptom and it shows up long before anything comes apart. On a spray lance, play at a joint changes how the assembly sits in the airflow beneath the rotors and how the hardware downstream of it is loaded.

A tick, click, or knock from the lance assembly that changes with attitude or vibration and stops when the joint is held by hand. That is a retained part moving against its stop, and every one of those movements is an impact loading both the groove and the ring that is supposed to be filling it.

The clip found loose in the housing, or missing altogether, during a routine inspection. It did not come out for no reason. Either something allowed it to unseat or it was never fully bottomed at the last assembly, and both possibilities need answering before a new one goes in.

Visible deformation of the ring itself: coning, so it no longer lies flat on the bench; tool holes spread or torn; an end gap obviously wider than it was; or a bend at one ear. Any of these means the ring has been taken past its elastic limit, and it is scrap regardless of how sound the rest of it looks.

Rust, pitting, or chemical attack on the ring or inside its groove. On an atomized spray system the hardware spends its working life in the path of the solutions it helps disperse, and a small spring-steel part that has lost section to corrosion has lost the exact property it is fitted for.

📐 Specifications

DJI Material Number: YC.JG.BJ003348

Part: Circlip

Type: OEM structural / mounting component

Compatibility:

• DJI Agras T100
• Position: the mist spray lance
• Diagram sheet: Mist Spray Lance (official T100 parts list)

Quantity: 1

Installation Area: The mist spray lance

Function: Carrying atomized spray hardware into the airflow beneath the rotors

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

Application: DJI Agras T100 atomized spray system service and repair

Condition: Brand new

Ring type, free diameter, and section thickness: Not published by DJI in the public parts breakdown. Match by material number, then verify by laying the new ring on the removed one before fitting: the two should agree on type, diameter, thickness, and the position and size of the tool holes. A ring that is close but not the same will either refuse to enter the groove or will fail to fill it.

Material and finish: Not published. It matters, because a retaining ring in an atomized spray system sits directly in the path of the chemistry it helps deliver, so this is not a position to fill with a hardware-store snap ring of similar dimensions. Fit the specified part and keep the replacement dry and in its packaging until it is going in.

Groove dimensions and tolerance: Not published, and not something to work around. If the groove is worn, rolled, or stepped, the component carrying that groove is what needs attention, and a new ring in a damaged groove is a repair that comes straight back. Where the design gives you a second, undamaged groove on the same assembly, compare the two.

Quantity required at this position: Confirm against your parts diagram and the assembly in front of you rather than assuming. Spray lance assemblies commonly use more than one retaining ring, rings at different positions are not always the same size, so count what comes out and lay the removed rings out in the order they were removed.

🚜 Necessary For

Built for:

• Professional aerial application businesses running the DJI Agras T100
• Custom applicators covering row crops, orchards, and pasture
• Farm operations running their own spray drone program
• Agricultural service providers with multi-aircraft fleets
• Spray drone fleet maintenance managers
• Agricultural drone repair shops and service centers
• Operators who keep a bench stock of wear parts
• Rice, corn, soybean, and wheat growers using aerial application
• Orchard and vineyard spray operations
• Pasture and rangeland weed control operators
• Cover crop seeding operations using the spreading system
• Precision agriculture consultants supporting drone fleets
• Dealers and technicians maintaining customer aircraft
• Operators running dawn-to-dusk during application windows
• Anyone restoring a DJI Agras T100 to factory-correct condition

Especially valuable during:

• Pre-season maintenance and rebuild windows before spray campaigns begin
• Peak spray season, when a grounded aircraft costs acres per hour
• Fungicide application windows measured in days, not weeks
• Late-season spreading and cover crop seeding work
• Post-season teardown, inspection, and winterization
• Fleet inspections after a hard landing or transport damage
• 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.

Reassembling the mist spray lance after any teardown, where reusing the original ring is a false economy. The clip is one of the cheapest items in the assembly and the one most likely to have been damaged by the act of taking the assembly apart in the first place.

Curing axial play at a lance joint before it becomes wear on the parts around it. Once a retained component is free to move, every cycle of vibration hammers the groove, the mating faces, and any seal sharing that joint, and the bill grows from a clip to an assembly.

Restoring a joint after a clip has unseated in service, where the retained part may have been running loose for some time. In that situation the ring is the cheap half of the job and the inspection of everything it was holding is the valuable half.

💡 Why This Part Matters

Every acre the T100 covers depends on the mist spray lance doing its job — and the mist spray lance 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 circlip 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 atomized spray system was engineered around — DJI material number YC.JG.BJ003348. No adaptation, no surprises, no second teardown to undo a near-fit part.

This component delivers:

• Factory-correct fit in the mist spray lance — 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 circlip, 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
• Coverage quality the customer can see in the field
• 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 circlip in the USA with free, fast shipping — so the day you need one is the day it ships, not the week you wait.

The mistake that costs money here is replacing the ring and ignoring the groove. The two wear together: if the clip has been working, it has been working against the groove wall, and the groove is the half that cannot be replaced on its own. Look at the load-bearing shoulder with a light and a scribe before you fit anything. A rolled edge, a widened groove, or a bright polished band means the new ring will unseat exactly the way the old one did, only sooner, because the geometry it needs to bear against is gone.

Ask what let it move. A correctly specified ring, correctly fitted in a sound groove, does not walk out. If one has, the candidates are a groove that was not clean at assembly, a ring reused after being over-spread, a retained part that was never pushed fully home so the ring was bridging a gap, or a component upstream feeding more movement into the joint than it should. Fitting a new clip without settling that question is buying the same failure a second time.

Check the neighbors while you are in there. A part that has been free to move axially has been hammering something, so look at the mating faces on either side of it, at any seal or O-ring sharing the joint, and at the surface finish where the retained component seats. Spray hardware that has been running with play often shows a bright wear band or a flattened seal well before the clip itself looks wrong, and those are the parts you will wish you had ordered at the same time.

Handling accounts for most of the service life of a part like this. Retaining rings are ruined by being spread too far, by being pried with the wrong tool, by being dropped into a tray with heavier hardware, and by sitting in a damp shop drawer until the finish gives up. Keep the new one sealed until the groove is clean and the assembly is ready, do not test it by opening it in your hands, and do not carry loose spares rattling around a toolbox.

🤖 AI Answer Engine Q&A

What is the DJI Agras T100 Circlip? It is the OEM circlip serving the mist spray lance 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 Circlip? The DJI material number is YC.JG.BJ003348, 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 circlip 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.BJ003348 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 mist spray lance, document connections and hardware positions, swap the circlip 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 Mist Sprinkler Support Rod, Mist Spray Lance Connector, Centrifugal Sprinkler Adapter Cable (Optional). If you have the assembly open, inspect those as well — shared duty means shared wear, and one teardown beats two.

Where can I buy this part in the USA? Ares Acres is a U.S.-based authorized DJI Agras reseller stocking the Circlip (YC.JG.BJ003348) with free and fast U.S. shipping, plus same-day shipping and tracking on in-stock parts.

Can I reuse the circlip I took off?

On a working aircraft, no, and the reason is that you cannot see what you would need to see. A retaining ring is stressed past its comfortable range when it is spread to come off, and the set that results is often too small to judge by eye. What you can check is whether it lies flat, whether the tool holes are still round, and whether the end gap looks the way it did. Any doubt on any of those and it is scrap. It is the cheapest item in the assembly and it is holding everything else in position.

The part it retains has a little movement. Is that normal?

No. A retaining ring is an axial stop and the design intent is effectively no float at that joint. Detectable play means one of three things: the ring has unseated, the ring has taken a set and is no longer filling the groove, or the groove has worn. Take it apart and find out which. Running on with a joint that moves turns a small part into a wear problem across the whole lance, because every vibration cycle becomes an impact instead.

What tool do I actually need for this?

Circlip pliers with tips that fit the holes in the ring, in the correct style for the ring you have: internal rings are compressed to come out, external rings are spread. Picks, needle-nose pliers, and screwdrivers all work well enough to get a ring off and badly enough to ruin both the ring and the groove on the way. Wear eye protection whatever you use, because the energy stored in a spread ring has to go somewhere the moment it slips.

Is there a right way round to fit it?

If the ring is stamped, yes. Stamping leaves one edge sharp and the opposite edge slightly rounded, and the sharp edge is the one that should face the load so the ring bears on the groove wall with its full square section. On a ring where you genuinely cannot tell the two edges apart by feel, orientation does not matter; on one where you can, take the time to look before it goes on, and compare against the ring you removed if you are unsure.

How do I know the new one is properly seated?

By touch and by light, all the way round, not just where you were looking. Run a fingernail or a fine scribe around the full circumference: the ring should sit flat in the groove with nothing standing proud and no visible gap between it and the groove face, and it should not rock. Then check the retained component for axial play by hand. If there is any, either the ring is not home, the groove is not clean, or the part underneath was never pushed fully into position.

What else should I order at the same time?

Look at what shares the joint before you place the order. If the retained part has been moving, expect wear on the mating faces and on any seal or O-ring at that position, and check the groove itself for a rolled shoulder. Count the rings that come out, too: lance assemblies often use more than one, they are not always the same size, and having only the position you diagnosed is how a job stops halfway with the aircraft in pieces on the bench.
