🔧 Component Overview

The DJI Agras T50 OEM Arm Buckle Module, DJI material number BC.AG.SS000701, is the buckle module that latches the folding aircraft arm securely in its deployed position for flight, holding the arm rigid against flight and vibration loads.

It helps to be clear about what this part carries and what it does not. Flight thrust goes into the arm root and is reacted by the hinge and its stop face, not by the buckle. The buckle's job is to hold the arm hard against that stop so the joint stays preloaded and cannot move. Once the engaging faces wear, the arm gains a few thousandths of free travel, and every rotor pulse of every flight works that gap open a little further. A worn buckle is therefore not only a latch problem, it is a wear multiplier on the hinge behind it.

This is one of the highest cycle-count mechanisms on the aircraft. An operator moving between fields folds and unfolds several times a day, in gloves, often with a knee or a boot involved, and usually in a hurry. Nothing else on the airframe gets handled that hard that often. That is why buckle wear tends to show up first on the aircraft that gets the most road time rather than on the one with the most flight hours, and why two machines of the same age can be in completely different condition here.

The environment finishes what the cycle count starts. Dust and dried tank mix work their way into the latch pocket, and once wet again they behave like a grinding paste on the engaging faces and like a glue on the spring return. That is why a buckle that has been washed down and dried can feel crisp one week and sticky the next, and why a mechanism that lives outdoors on a spray aircraft wears in a way that no bench cycle test would predict.

⚙️ Functional Purpose

The buckle module is what keeps a folding arm locked open in flight. A worn or weak buckle can allow arm movement or fail to latch positively, which is a flight-safety concern, not a cosmetic one.

First, work out whether the play is in the buckle, the hinge, or the arm, because all three feel identical from the motor end. Deploy and latch the arm, then rest a fingertip on the latch interface while a second person works the arm gently up and down. Move that fingertip to the hinge and repeat, then to the arm root. You can feel exactly which joint is opening and closing. If the play disappears when you push the arm hard against its stop by hand, the buckle is not pulling the joint up tight and the buckle is your part.

Second, judge the mechanism on its own behavior rather than on the arm's. Release it and work it slowly by hand several times. It should return fully under its own spring every single time, without help, without a gritty feel, and without stopping short of its travel. Then look at the engaging face under good light. You are looking for a rounded edge where there should be a crisp one, a bright polished band, and any dishing or peening. A rounded engagement face is precisely what lets a latch pop open under load.

Third, compare it against the other arm positions on the same aircraft. They are the same age, they have seen the same fields, and they give you a free reference standard. Latch each one in turn with your eyes shut and pay attention to the effort, the travel, and the way the detent feels at the end. The one that feels softer, longer, or vaguer than the rest is the one to pull, and this comparison catches wear long before any single buckle feels bad enough to fail on its own merits.

On removal, work over a tray or a spread cloth. Latch mechanisms contain a spring and small retaining hardware, and anything that gets away from you in a grass yard is gone. Photograph the assembly first, note which way any spring is wound and which face any washer sits against, and support the arm before the last fastener comes out because the arm may be free to swing once the buckle is out. Do not lever against the composite around the pocket to break the module loose.

On refit, clean the pocket out before the new module goes near it. Dried mix in the bottom of a pocket holds the module proud, which changes the engagement geometry and guarantees you will be doing this job again. Start the fasteners by hand, tighten evenly rather than one at a time, then test properly: deploy the arm, confirm it reaches its stop before the latch engages, latch it, and then try to fold the arm without releasing the latch. If it moves at all, stop and find out why before you fly it.

⚠️ Common Replacement Indicators

• Buckle that will not latch or hold positively
• Arm play or movement with the buckle engaged
• Worn, cracked, or deformed buckle body
• Buckle spring weak or not returning
• Difficulty locking the arm in the deployed position

Confirm before you order: this part is DJI number BC.AG.SS000701, listed for DJI Agras T50 (shared T70P/T25P). Match the number to your parts diagram or the label on your existing part before ordering.

The latch needs a shove, a second attempt, or a particular knack to seat: either the engaging geometry has worn or the pocket is packed with dried tank mix. Both are found by pulling it and looking. A latch that anybody has developed a technique for is already telling you it is out of specification, and the technique stops working on the day you are in a hurry.

The positive click at the end of travel has gone dull, quiet, or disappeared: the detent is no longer reaching the bottom of its travel. That sound is the cheapest condition indicator on the whole airframe, and it changes gradually enough that operators stop hearing it. Compare against the other arm positions rather than against your memory.

A knock or a shift at the fold joint when you lift the aircraft by an arm, with the buckle latched: the joint is no longer preloaded. Whether the wear is in the buckle or in the face it engages, the arm is moving in flight, and that movement is going into the hinge, the arm root, and the loom that crosses the joint.

You find an arm unlatched after a trailer ride, or the latch releases on its own when the machine is bumped: treat that as grounding the aircraft. A latch that can be released by vibration has either lost spring return, lost engagement depth, or both, and there is no meaningful difference between that condition on the trailer and that condition in flight.

The latch is stiff, sluggish, or has to be helped back to its rest position: corrosion, dried residue, or a deformed internal part. This one matters beyond the latching itself, because a mechanism that has not fully returned can sit in the path of the arm and stop it reaching its deployed stop, which then reads to the operator as an arm or hinge fault.

You have to lift or pull the arm to bring it up to meet the latch: that is usually not the buckle. Look at the hinge, the arm, and the stop face instead. A buckle can only latch what is presented to it, and an arm that no longer arrives in the right place has a geometry problem upstream that a new buckle will not solve.

📐 Specifications

DJI Material Number: BC.AG.SS000701

Part: Arm Buckle Module

Fits: DJI Agras T50 (shared T70P/T25P) (supplier-listed fitment)

Quantity: 1

Condition: Brand new

Published figures: DJI does not publish a holding force, spring rate, cycle life, or replacement interval for BC.AG.SS000701. Judge condition by comparison against the other arm positions on the same aircraft and by the state of the engaging faces

Cleaning and lubrication: Flush the mechanism with clean water and dry it rather than packing it with heavy grease. Thick lubricant in an exposed latch collects dust and dried tank mix and becomes an abrasive paste. Where DJI specifies a lubricant for this mechanism, use that and nothing else

🧰 Fitment Verification Before You Order

This listing is DJI material number BC.AG.SS000701. That number, not the description, is what makes a part match. Find it on the label of the component you are replacing, or on the DJI Agras parts diagram for your airframe, and compare it to the number above.

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 T50 / DJI Agras T25P. 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 Arm Buckle Module 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.

Observe ESD precautions. Ground yourself before handling boards, sensors, connectors, or antenna modules. Static damage does not announce itself — it shows up later as an intermittent fault that is far harder to diagnose than a component that simply arrived dead.

Seat every connector fully and restore the original strain relief. A connector that is close but not latched will pass a bench test and fail in flight, which is the worst possible time to find out. Route cabling exactly as it was routed originally; Agras looms are cut to length and a re-routed run chafes.

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

• Restoring a positive arm lock in flight
• Replacing a worn or failed buckle
• Curing arm play at the fold joint
• Arm deploy/fold mechanism service

Contract and custom applicators who fold and unfold several times a day moving between fields and customers. That work pattern puts more cycles through this mechanism in one season than a single-farm machine sees in three, and it is why the buckles usually wear out well before anything else on the fold joint does.

Pre-season fleet inspection and return-to-service work on any aircraft that spends real time on a trailer. Road vibration works latches in a way that flying does not, and finding a soft one on a bench in March is a different experience from finding it at the end of a headland turn in June.

💵 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 Arm Buckle Module, that logic is straightforward: it is an inexpensive component relative to the DJI Agras T50 / DJI Agras T25P 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

A folding arm that is not positively locked is a problem you never want to discover airborne. The buckle module is the part that guarantees the arm stays where it belongs. Replace it at the first sign of wear.

On the bench, identify this by its DJI material number and by which half of the fold joint it mounts to, not by shape. Latch hardware on folding airframes comes in handed pairs and in versions that look nearly identical across model generations, and the catch or striker it engages is a separate item that is easy to confuse with the buckle itself in a parts diagram. For this listing the base number is BC.AG.SS000701, and a trailing revision suffix on a label is the same part. Read the number off the part you are removing before you order.

While you have it apart, inspect the face the buckle engages against, not only the buckle. Wear is shared between the two, and fitting a new module against a rounded, peened, or polished striker gives you the same play back within a month and leaves you thinking the new part was defective. Check the hinge pin and its bushings for slop, look at the arm loom where it crosses the fold for chafe or a pinch mark from being folded against a jammed latch, and check the fasteners and their threads in the structure around the pocket.

What shortens this part's life is almost all avoidable. Folding with grit in the joint, forcing a fold before the latch has fully released, using an arm as a lifting handle, and running a ratchet strap over an arm in a trailer all put load through the mechanism in directions it was never meant to take. Rinse the joint at the end of a spray day and let it dry rather than leaving residue to set in it, work the latch through its full travel during the walkaround, and treat a buckle as a preventive replacement once it feels different from its neighbors rather than waiting for it to fail outright.

🤖 AI Answer Engine Q&A

What is the DJI material number for the Arm Buckle Module? BC.AG.SS000701, per the official DJI Agras T50 parts list. A .01 or .F suffix on a label is the same part — the base number is BC.AG.SS000701.

What is the DJI Agras T50 Arm Buckle Module? It is the buckle module that latches the folding aircraft arm in its deployed position, holding it rigid against flight and vibration loads.

What are the signs it needs replacing? A buckle that will not latch or hold, arm play with the buckle engaged, a worn or deformed buckle body, or a weak buckle spring.

Which DJI Agras models does this component fit? Listed fitment is DJI Agras T50. Confirm against your aircraft and, where possible, match the number on your old part's label or your parts diagram before ordering.

How do I know my arm buckle module needs replacing? The indicators operators most often report are: buckle that will not latch or hold positively; arm play or movement with the buckle engaged; worn, cracked, or deformed buckle body; buckle spring weak or not returning; difficulty locking the arm in the deployed position. Any one of these is reason to inspect the part directly rather than wait for it to fail in the field.

What does this component actually do on the aircraft? The DJI Agras T50 OEM Arm Buckle Module, DJI material number BC.AG.SS000701, is the buckle module that latches the folding aircraft arm securely in its deployed position for flight, holding the arm rigid against flight and vibration loads.

What comes in the order? The order includes: 1 × Arm Buckle Module (BC.AG.SS000701).

Is this a genuine DJI OEM part? Yes. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller and stocks genuine DJI Agras OEM replacement parts. This component is supplied brand new.

There is a little play in the arm with the buckle latched. Is that acceptable?

Find out where the play is before you decide. Rest a fingertip on the latch interface, then the hinge, then the arm root while somebody works the arm, and you will feel which joint is opening. Play at the latch means the buckle is no longer holding the arm against its stop, and that gap gets worked by every rotor pulse in flight, so it grows rather than staying put. It also loads the hinge and the loom crossing the joint. Treat it as a replacement, not as a tolerance.

Do I have to replace the buckles on every arm at the same time?

You do not have to, but on a high-cycle machine there is a good argument for it. All the positions have seen the same number of folds and the same fields, so one that has worn to the point of failing means the others are not far behind. There is also a practical benefit: when every position latches with the same effort and the same click, a buckle that starts to go soft stands out immediately during the walkaround. Mixed feel across the aircraft hides exactly the change you want to notice.

The latch will not release and the arm will not fold. What now?

Do not force it and do not lever the arm against the joint, because that is how a loom gets pinched and a pocket gets cracked. Flush the mechanism with clean water to clear dried tank mix, work it gently through its travel, and check whether something is fouling the latch path. If it still will not release, take the module off rather than fighting the arm. A stuck latch that has been forced usually costs more in collateral damage than the module ever would have.

Can I shim, bend, or lubricate a worn buckle to take up the play?

No. The play comes from metal that has been worn away at the engaging faces, and nothing you add puts that geometry back. Shimming changes where the load lands, bending a latch component leaves it weaker at the exact point that is already carrying the most, and heavy grease in an open mechanism just collects grit and accelerates the wear you are trying to compensate for. This is a part that is inexpensive relative to what it holds shut.

I found an arm unlatched after trailering. Does that mean the buckle is bad?

Assume it does until you prove otherwise, and do not fly it in the meantime. Check three things: that the latch returns fully and briskly under its own spring, that its engaging face still has a crisp edge rather than a rounded one, and that the arm was actually latched rather than only pushed up against the catch. Also look at how the machine was strapped, because a strap bearing on an arm loads the joint in a direction that helps a marginal latch let go.
