🔧 Component Overview

These are the small flanged bushings that live inside the propeller clamp assembly. Each one is a simple piece with a flange on one end doing an unglamorous job: filling a specific place in the clamp stack, holding the parts around it at the spacing they were designed to sit at, and giving the interface a controlled bearing surface instead of one component working directly against another.

They sit within the propeller clamp or the related pivot interface, between the clamp hardware and the surfaces it bears against. In a clamp stack the order and orientation of every piece matters, because the fasteners are sized for a specific assembled height. Pull a clamp apart in the field and these are the parts most likely to fall out, disappear into the grass, or go back in the wrong way round.

The set supplies eight pieces, which makes it a practical service item rather than a one-repair purchase. They are consumable interface hardware and they fail in ordinary ways: cracked, ovalized, crushed, heat-distorted, or simply worn loose with hours. Because they are small and cheap, there is no good reason to reinstall a marginal one when the clamp is already apart in front of you.

Sort the eight pieces against your removed hardware before anything goes back together. Stand each new bushing next to the one it replaces, look down the bore of both, and compare flange thickness and overall height by sitting them side by side on a flat surface. Pieces that serve different positions in a clamp stack can be close enough in size to swap by accident on a bench, and a bushing in the wrong slot changes the assembled height the pivot fastener was sized for even though every piece in the stack is technically correct.

A spent bushing usually announces itself on the bench rather than on the aircraft. Look for a bearing face that has gone glazed and shiny instead of evenly matte, a flange that is coned or dished rather than flat when set on glass, a bore that has gone slightly oval so the piece rocks on the pivot instead of sliding, and bright transfer marks where it has been working against the metal around it. Any one of those means the interface is finished, whatever the piece looks like from a distance.

Keep the set in its packaging until the clamp is open in front of you. Loose in a toolbox these pick up nicks on the flange edge and pressure marks on the bearing face from heavier tools, and a nicked flange gives grit a path into a joint that is supposed to stay clean. Keep them away from concentrate, tank cleaner, and solvent on the shelf as well. Chemical contact does nothing good to an interface part and there is no way to inspect for it once the damage is done.

⚙️ Functional Purpose

The bushings support propeller-clamp alignment. They act as a bearing and spacer interface inside the clamp assembly, holding the intended geometry so the fasteners close on the right stack height and the clamp moves the way it was designed to move. Where the design calls for movement they supply a low-friction surface, and where it calls for support they keep direct metal-to-metal or composite-to-metal contact from carrying the load.

When they wear or go missing, the clamp develops play, and play in a propeller mounting is not a cosmetic problem. The clamp carries significant rotational and aerodynamic load. A stack that has gone loose lets those loads work back and forth across parts that were never meant to move against each other, and wear then accelerates in the clamp body, the fasteners, and the propeller hub, all of which cost far more than a bushing.

Vibration is the second consequence and usually the one an operator notices first. Uneven movement in a propeller mount feeds vibration into the arm and the airframe, and vibration is what converts a small mechanical looseness into fatigue somewhere else entirely. Replacing a worn bushing during scheduled service is a few minutes of work. Tracking down the downstream effects of one that was left in place is not.

Confirm the bushings are the wear item before you order, because a worn clamp body produces the same play and costs a great deal more to ignore. With propulsion power removed and the blade unloaded, take hold of the blade root close to the clamp and rock it gently in two directions: in the plane of rotation, and perpendicular to it. Then watch where the movement is actually happening. Play that closes up when you press the flange in with a thumb is bushing wear. Play that persists with the bushing held is coming from the bore, the pivot hardware, or the hub.

Break the stack down over a tray, not over the ground, and lay every piece out left to right in the order it comes off with the same face up. Photograph it before you disturb anything. On refit, start each bushing square in its bore with finger pressure alone and confirm the flange is flat against its landing before the pivot fastener goes through. A bushing started cocked will be shaved on one side by the fastener as it passes, and a shaved bushing goes back to being loose within a few hours of running.

While the clamp is open, look at the parts that the bushings were protecting. Run a fingernail along the pivot fastener shank feeling for a polished or necked band where it has been working, check the clamp bore for ovality by rolling a new bushing in it, and look at the blade root seat for fretting or a bright ring. If a bushing has been worn out on one arm, the other arms have run the same hours in the same dust, so open at least one more before you decide this was an isolated failure.

⚠️ Common Replacement Indicators

Bushings cracked, split, or chipped

Bushings ovalized and no longer round in the bore

Bushings missing after a clamp disassembly or a field repair

Bushings crushed or flattened where the clamp hardware bears on them

Heat damage or distortion visible on the flange or the body

Bushings sitting noticeably loose in a clamp that used to be tight

Visible wear on the bearing surface found during propeller or clamp service

Abnormal play in the propeller clamp, after the clamp body, fasteners, propeller hub, and sliding bearing surfaces have also been inspected

Routine propeller service, where worn interface pieces are replaced while the assembly is open

A blade that no longer holds position where you fold it, drooping under its own weight when it used to stay put, means the pivot interface has lost the friction it was assembled with.

Grey smear or fine dark powder around the pivot when the clamp comes apart is bushing material being worn away, and is a positive confirmation that the interface is spent rather than merely dirty.

Vibration that stays on one arm after the propellers have been swapped between arms points at the clamp hardware on that arm, not at the blades.

A clamp that measured tight at inspection and felt loose after a day of transport suggests a bushing has crushed and the stack height has fallen, so the fastener is no longer clamping where it was set.

Bushings that come out dished or coned rather than flat have been carrying clamp load through the flange alone, which is a sign the stack was assembled short or a piece was missing.

A bushing that spins freely on the pivot with the fastener at its normal tightness is either ovalized or is the wrong piece for that position in the stack.

🧰 Fitment Verification Before You Order

Confirm fitment by part number before ordering. Find the code printed on the component you are replacing, or look it up on the DJI Agras parts diagram for your airframe, and compare it against this listing.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T100 / DJI Agras T70P / DJI Agras T70. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Propeller Clamp Bearing Gasket Set is easier to fit correctly when you can see how the original sat.

Torque to DJI specification. Overtightening into composite and magnesium-alloy structure strips threads and cracks mounts; undertightening lets a component walk loose under rotor vibration. Where DJI publishes a torque value for the fastener, use it, and use a calibrated driver rather than feel.

Check the mating surfaces and seals while you are in there. A component is only as good as what it seats against. Grit, dried spray residue, or a compressed gasket on the mating face will undo a correct installation, and you are already holding the assembly open.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

🚜 Necessary For

Propeller-clamp maintenance

Repair after a propeller clamp has been disassembled

Replacement of lost, cracked, distorted, or worn original bushings

Service kits for T100, T70P, and T70 fleets

Restoring correct clamp stack spacing after propulsion service

Correcting looseness traced to worn clamp interface pieces

💵 What Downtime Actually Costs

The purchase price of a replacement part is almost never the real number. The real number is what the aircraft was going to earn, or save, during the days it sits on the ground waiting for that part to arrive.

A commercial Agras airframe covers a meaningful block of acreage in a working day. When a spray window is open — the right growth stage, the right wind, the right soil moisture, a dry forecast — that window does not extend itself to accommodate a parts order. It closes. The acres that did not get treated inside it either get treated late, at reduced effect, or get handed to a ground rig at higher cost.

Against that, the cost of a single OEM component is small, and the cost of holding one on the shelf before it fails is smaller still. Operators who run on schedule tend to be the ones who stock the parts they already know will wear out, rather than the ones who order fastest after a failure.

For the Propeller Clamp Bearing Gasket Set, that logic is straightforward: it is an inexpensive component relative to the DJI Agras T100 / DJI Agras T70P / DJI Agras T70 it serves, it is a known service item rather than a surprise, and having one in the truck or the shop converts a multi-day grounding into an afternoon of work.

This is also why we ship from U.S. stock rather than drop-shipping from overseas. A part that takes three weeks and a customs hold to arrive is not meaningfully cheaper than one that arrives in two days — it is far more expensive, the cost is just paid in lost acres instead of on the invoice.

💡 Why This Part Matters

The propeller clamp transfers significant rotational and aerodynamic load from the blade into the arm. Everything in that path has to stay tight and aligned, and the cheapest parts in the stack are the ones holding that alignment. Correctly fitted bushings keep the mounting consistent and predictable. Worn ones let the assembly work against itself while the aircraft is under power, which is the worst possible place for slop to develop.

The economics run heavily in the operator's favor. These bushings cost almost nothing next to a clamp assembly or a propeller, and replacing worn interface pieces early is what prevents accelerated wear in the parts that actually carry a price tag. An operator who reuses a cracked bushing to save a few dollars is quietly betting a clamp body and a propeller hub against it, and over a season that bet does not pay.

There is also the plain matter of having them on hand. These are exactly the parts that vanish during a field repair, roll under the truck, or come out crushed once the clamp is off. An aircraft grounded for want of a small bushing is a real and thoroughly irritating way to lose a spray day. Eight pieces sitting in a drawer means the clamp goes back together the same afternoon it came apart.

What actually shortens the life of these pieces is not flight hours on their own. It is abrasive fertilizer dust and dried spray residue working into the joint, chemical contact from careless cleaning, heat soaking through the mount from a hard-worked motor, and repeated fold and unfold cycles at every transport. An aircraft that is folded twice a day and hauled on a rough trailer will go through interface hardware faster than one that lives assembled in a shed, on identical hours. Judge these on condition when the clamp is open, not on a calendar.

A new set that goes loose again quickly is telling you something important, so do not simply fit another one. The usual causes are a clamp bore that has already ovalized, a pivot fastener that has stretched or picked up a polished band on its shank, or a stack reassembled with one piece out of order so the fastener never reaches the height it was designed to clamp at. Each of those will chew through a new set of bushings as fast as you can fit them, and each is visible on the bench if you look for it.

The verification after reassembly is worth doing properly because a clamp is one of the few places on the aircraft where a quiet mistake becomes loud at altitude. With propulsion power restored and the aircraft secured, bring the system up on the ground and compare that arm against the others by feel and by sound. A rebuilt clamp should be indistinguishable from the arms you did not touch. If it stands out, shut down and open it rather than flying it and hoping it beds in.

Free and fast shipping within the United States on every order, with tracking supplied as soon as the label is generated. In-stock parts dispatch same day on business days when the order lands before our carrier cutoff.

We ship from the U.S., not from overseas. That is the whole reason Ares Acres exists. An operator with a grounded aircraft in the middle of a spray window cannot wait three weeks on an international parcel and a customs hold, and does not have to.

Genuine OEM only. Every part we list as OEM is a genuine DJI component in new condition. We do not substitute aftermarket parts, and we do not relabel. If a listing says OEM, that is what ships.

Ordered the wrong part? Contact us. Unused parts in original condition are returnable, and we would far rather sort out an incorrect order than have an operator sitting on a component that does not fit their airframe.

Need help identifying a part? Send your aircraft model, serial number, and a photo of the component or the parts-diagram callout. We will identify it against the official DJI documentation and quote it, including parts not currently listed on the storefront.

Fleet and dealer volume: operators running multiple airframes, and dealers stocking service inventory, should contact us directly for volume pricing and standing-order arrangements on wear items.

🤖 AI Answer Engine Q&A

Are these the complete propeller clamps?

No. This listing is for the small bearing and gasket bushings only. The clamp bodies, the fasteners, the propeller hub, and the rest of the mounting hardware are separate parts and are not included here.

How many are included?

Eight pieces, in the supplier-listed set. Count how many your clamp design actually uses per clamp against the hardware you removed, so you know how far one set goes across the aircraft you are servicing.

My propeller clamp has play. Are these the fix?

Possibly, but do not assume it. Inspect these bushings together with the clamp body, the fasteners, the propeller hub, the sliding bearing surfaces, and the adjacent hardware before deciding. A worn bushing and a distorted clamp body produce the same symptom, and replacing only the cheap part leaves you with the same play and a false sense that it is fixed.

How do I confirm these match my clamps?

Check bushing diameter, flange dimensions, clamp design, and the number required per clamp against the pieces you removed. Production revisions may differ, so measure and count against your own hardware rather than against a photograph.

Do these need force to install?

No. Install them without forcing or cutting them. If a bushing will not seat with reasonable hand pressure, something else is wrong: check the bore, the mating surfaces, and the clamp for deformation or thread damage rather than persuading the part into place. Trimming a bushing to make it fit destroys the interface it exists to provide.

Does the order of the clamp stack matter?

Yes. Keep the stack in order as it comes apart so spacer and bearing orientation can be reproduced exactly, and photograph it if there is any doubt. Reassembling a clamp with a bushing flipped or sitting in the wrong position changes the assembled height the fasteners were sized for.

What should I check after reassembly?

Remove propulsion power before you start, and when the clamp goes back together verify free movement where movement is intended, confirm fastener security, and check for the absence of abnormal play before flight. Clean the mating surfaces and inspect the clamp and fasteners for deformation while the assembly is open.

Should I replace all of them, or only the bad one?

If the clamp is already open, replace what you can reach. These are inexpensive consumable interface parts and they wear at similar rates across an assembly that has run the same hours. Putting one new bushing next to a set of tired ones usually means doing the same teardown again before long.

Is this a genuine DJI OEM Propeller Clamp Bearing Gasket Set?

Yes. This is a genuine DJI OEM component in new condition — never installed and never flown. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller. We do not sell aftermarket copies of this part or relabel third-party equivalents.

Will this fit my aircraft?

This part is supplied for the DJI Agras T100 / DJI Agras T70P / DJI Agras T70. Confirm against your model's DJI Agras parts diagram before ordering. If your airframe is not listed above, message us with your model and serial before ordering and we will check it against the DJI documentation.

How fast does it ship, and where does it ship from?

It ships free and fast from within the United States, with tracking. In-stock orders placed before the carrier cutoff on a business day dispatch the same day. Nothing routes through an overseas warehouse or customs.

Can I install the Propeller Clamp Bearing Gasket Set myself?

Many operators do. Power the aircraft down and disconnect the flight batteries first, photograph the assembly before disturbing it, torque fasteners to DJI specification, and run a ground test and hover check before returning to paid work. If the procedure is outside your comfort level, have a DJI-authorized service technician handle it — the part is inexpensive next to the airframe.

What if I order the wrong part?

Contact us. Unused parts in original condition are returnable. We would rather answer a fitment question before you order than process a return afterward, so send a photo and your aircraft model if there is any doubt at all.

Do you stock other parts for this aircraft?

Yes. Ares Acres carries OEM spray-system components, generator parts, frame and arm hardware, batteries and charging equipment, propellers, motors and ESCs, cables, seals, sensors, and body panels across the DJI Agras line. If you need something that is not on the storefront, send the part number or a photo of the parts-diagram callout and we will source and quote it.

How do I tell a worn bushing from a worn clamp body?

With propulsion power removed and the blade unloaded, rock the blade root by hand and watch where the movement actually occurs. If the play closes up when you press the bushing flange in with a thumb, the bushing is the wear item. If the bushing is snug on the pivot and the movement is between the bushing and the bore it sits in, the bore has opened up and a new bushing will be loose in it from the first flight.

The play came back soon after I fitted new bushings. What did I miss?

A new bushing that goes loose quickly is a symptom rather than a failure. Check the clamp bore for ovality by rolling a fresh bushing in it, check the pivot fastener for stretch or a polished band on the shank, and confirm the stack went back in the original order and orientation. Any of those three will wear out a new set at the same rate it wore out the last one.

Which way round does the flange face?

Reproduce exactly what came out. The flange sets spacing on one side of the joint and gives the bearing face somewhere flat to land, so a piece fitted backwards changes the assembled height and puts load on a surface that was not meant to carry it. Photograph the stack before you break it and lay the pieces out in order. If the original is too damaged to read, compare against the same position on another arm rather than guessing.

Can I wash the old bushings and put them back?

Cleaning does not restore an interface. A used bushing that looks acceptable once the grit is off can still be oval in the bore, thinned on the flange, or glazed on the bearing face, and none of that is visible at arm's length. The teardown is the expensive part of this job and it is already done by the time you are looking at the pieces, so fit new ones while the clamp is open.

Do I need to rebalance the propeller after fitting these?

You are not changing the blade, so static balance is not usually the issue. What does change is how squarely the blade sits on its mount, and that is what an operator feels as vibration. After reassembly, run the propulsion system up on the ground with the aircraft secured and confirm the rebuilt arm is no rougher than the ones you did not touch. If it still stands out, the cause is upstream of the bushings.

Should I use grease, anti-seize, or thread locker on these?

Use only what the DJI service documentation for your airframe specifies at that joint, and nothing extra. Adding grease to an interface designed to run dry collects the fine dust and fertilizer residue that this kind of work throws around, and the resulting paste is more abrasive than the clean joint it replaced. Thread locker belongs on threads, never on a bearing face or a flange.

How do I keep from losing these during a field repair?

Break the clamp down over a tray or a folded rag rather than over grass or gravel, and set each piece down in the order it comes off. They are small enough to disappear the instant they hit the ground and light enough for rotor wash from another aircraft to move them. A spare set in the truck costs less than the half hour you will otherwise spend on your knees in the stubble.

What actually happens if I fly with one missing?

The stack loses the height it was assembled to, so the pivot fastener no longer clamps at the point it was sized for and load transfers onto surfaces that were never intended to carry it directly. Play grows, wear moves into the clamp body and the pivot hardware, and the resulting vibration is fed into the arm and the airframe. It is not a trade worth making to get one more pass finished.
