{"product_id":"dji-agras-t40-oem-aircraft-arm-friction-plate-set","title":"DJI Agras T40 OEM Aircraft Arm Friction Plate Set","description":"\u003cp\u003eThe DJI Agras T40 OEM Aircraft Arm Friction Plate Set is a pair of flat black friction plates for the aircraft arm, supplied as one of each shape: a tall plate with a rounded top corner and a large round hole, and a shorter angled plate with a sloping top edge and a small round hole near its upper corner. They belong to the frame and arm hardware of the aircraft, not to the spray, power or flight-control systems, and they are identified for the DJI Agras T40 and T20P. Operators usually come looking for them while searching for a T40 arm friction plate, a T20P arm friction pad, a missing plate found during arm service, or a replacement for a plate that has cracked, torn or worn at its hole. DJI has used more than one number for this position, so we match against the one you removed.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🇺🇸 U.S.A.

It has no moving parts, no wiring and no adjustment. What it has is an outline and a hole, and those two features are the whole of its identity: the outline decides where it can sit, and the hole decides what passes through it.\u003c\/p\u003e\n\u003cp\u003eThe set contains two plates that look like relatives and are not twins. Laid side by side they are easy to tell apart:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe tall plate\u003c\/strong\u003e — the larger of the two, upright and roughly rectangular, with one top corner cut at an angle and the other rounded, and a large round hole set close to the top\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe angled plate\u003c\/strong\u003e — shorter and wider, with a long sloping top edge running up to a rounded corner, and a small round hole set in that upper corner\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoth plates\u003c\/strong\u003e — flat, black, plain-faced, with no printed markings visible in the product images\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe part designation places them at the aircraft arm. A friction plate's job in any mechanical joint is to sit between two surfaces that bear against each other, so that they bear on the plate rather than directly on each other. That makes the plates the sacrificial layer in the joint: they take the rubbing and the clamping so that the moulded or machined faces either side of them do not.\u003c\/p\u003e\n\u003cp\u003eOver a working season arm hardware sees:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eArm folding and unfolding at the start and end of every working day\u003c\/li\u003e\n\u003cli\u003eTransport on trailers and in vehicles with the arms folded\u003c\/li\u003e\n\u003cli\u003eVibration through the frame on every flight\u003c\/li\u003e\n\u003cli\u003eArm strikes against trees, posts, trailers and vehicles during handling\u003c\/li\u003e\n\u003cli\u003eChemical residue and wash water that run down the arms and collect at the joints\u003c\/li\u003e\n\u003cli\u003eHeat on the trailer and in the sun between flights\u003c\/li\u003e\n\u003cli\u003eRepeated disassembly of the arm joint during service and crash repair\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePlates in this position usually come out for one of four reasons: a plate has cracked or torn, a hole has worn out of round, a plate has been distorted by an impact or by clamping, or a plate has simply gone missing during an earlier arm repair. The last one is more common than it sounds. A thin black plate that drops out of an arm joint onto a dark workshop floor is easy to lose and easy not to notice.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\n\u003cp\u003eThe plates' engineering role is to be the controlled contact surface in the arm hardware. They sit where the part designation puts them, at the aircraft arm, and they give the surfaces around them a defined, replaceable layer to bear against.\u003c\/p\u003e\n\u003cp\u003eIn the arm hardware they:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eProvide a flat bearing layer between surfaces that would otherwise contact each other directly\u003c\/li\u003e\n\u003cli\u003eLocate on whatever passes through their holes, so each plate sits in one place and one orientation\u003c\/li\u003e\n\u003cli\u003eTake the rubbing and clamping load that would otherwise wear the faces either side\u003c\/li\u003e\n\u003cli\u003eFill the space they were designed to fill, so the parts around them sit at the spacing DJI intended\u003c\/li\u003e\n\u003cli\u003eCan be replaced on their own when worn, without replacing the arm or the parts they protect\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhat they do not do matters as much:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThey do not carry the aircraft in flight; the arms and arm connectors do that\u003c\/li\u003e\n\u003cli\u003eThey are not the arm locking rotation shaft, which is a separate part sold as its own pack\u003c\/li\u003e\n\u003cli\u003eThey do not latch, lock or fold the arm on their own\u003c\/li\u003e\n\u003cli\u003eThey carry no wiring and have no electrical function\u003c\/li\u003e\n\u003cli\u003eThey do not seal the arm against liquid\u003c\/li\u003e\n\u003cli\u003eThey will not straighten a bent arm or close up a cracked arm connector\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThat is why a missing or worn plate rarely grounds the aircraft outright, and why it is so often left out of an arm repair that otherwise looks finished.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🔍 Diagnosis — the outline and the hole name the plate, so match both before you fit either\u003c\/h2\u003e\n\u003cp\u003eThe most common mistake with these plates is not a failed part. It is a correct part in the wrong place, or the same shape fitted twice. Two flat black plates of similar size come out of an arm joint together; one goes back where the other came from, or a second copy of one shape is pressed into service because it was what was in the parts tray. The joint goes back together, and it is wrong.\u003c\/p\u003e\n\u003cp\u003eThe plates prevent that themselves, if you read them. The tall plate carries a large hole; the angled plate carries a small one. Whatever passes through each plate's hole decides which plate belongs there. A small-hole plate cannot sit on a large-diameter part, and a large-hole plate slid over a small one has nothing locating it — it can shift, sit off-centre and wear unevenly. Matching the outline alone is not enough. Match the outline and the hole.\u003c\/p\u003e\n\u003cp\u003eThat is also why the set is one of each shape. A pair of identical plates would leave one position wrongly filled. Replacing both at once, from one set, keeps the two plates in a joint at the same state of wear.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSigns a plate needs attention:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eA plate that is cracked, torn, chipped at its edge, or split from its hole\u003c\/li\u003e\n\u003cli\u003eA hole that has worn oval or ragged rather than round\u003c\/li\u003e\n\u003cli\u003eA plate that is bent, dished or no longer lies flat\u003c\/li\u003e\n\u003cli\u003eA plate that is visibly thinner on one side than the other\u003c\/li\u003e\n\u003cli\u003eA plate missing from the joint when the arm is opened up\u003c\/li\u003e\n\u003cli\u003eOne arm joint that feels or sounds different from the others when the arms are folded and unfolded\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBefore blaming the plates, rule out what imitates them:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe arm locking rotation shaft\u003c\/strong\u003e — a worn or damaged shaft lets the arm move no matter how good the plates are\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe arm connector\u003c\/strong\u003e — a cracked or loosened connector produces play at the arm root that new plates will not remove\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA loose or missing fastener\u003c\/strong\u003e — one backed-off screw changes the clamping on every part in the joint\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA bent arm\u003c\/strong\u003e — if the arm itself is out of line, the joint will not sit square however it is assembled\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eUse the other arms as your reference.\u003c\/strong\u003e Fold and unfold each arm by hand and compare how they feel and sound.

Nothing throws an error. The arm still unfolds and still locks. The joint simply runs with a contact surface missing, misplaced or doubled up.\u003c\/p\u003e\n\u003cp\u003eThe case for a matched set is about naming, not strength. The two plates are different parts. One has a large hole and one has a small one, and the hole decides where each plate goes. A set that contains one of each shape puts the right plate back in each position; two of the same shape, or one new plate beside one worn one, does not.\u003c\/p\u003e\n\u003cp\u003eWhen the plates are wrong, the wear does not stay in the plates. The surfaces they were meant to protect start to bear on each other, or on a plate that is not located on its hole. That moves the wear onto the shaft, the connector and the moulded faces of the arm hardware, and each of those is a larger repair than a pair of plates.\u003c\/p\u003e\n\u003cp\u003eThe check costs nothing while the joint is open. Lay the removed plates flat, compare their outlines and holes with the new set and with a sound arm, and fit each plate only where its shape and hole belong. If the removed plates are flat, whole and round at the hole, leave them in. If they are not, this is the set that puts both positions back.\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.

They are identified for the DJI Agras T40 and T20P.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow many plates are in the set?\u003c\/strong\u003e Two. One tall, large-hole plate and one angled, small-hole plate. It is not two of the same shape.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the two plates interchangeable?\u003c\/strong\u003e No. They have different outlines and different hole sizes, and the hole decides which part each plate sits on. Fit the large-hole plate only where a large-hole plate came out, and the small-hole plate only where a small-hole plate came out.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich aircraft does it fit?\u003c\/strong\u003e It is identified for the DJI Agras T40 and T20P. Pick the variant for the aircraft you fly.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs the T20P set different from the T40 set?\u003c\/strong\u003e The set is identified for both aircraft. The variant records which one you fly so the match is made against the right airframe, and we compare it with the plates you removed if you send a photograph.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the DJI part number?\u003c\/strong\u003e DJI has used more than one number for this position, so we match against the one you removed. Photograph your old plates flat beside a ruler and send it to us if you want that confirmed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow many sets does my aircraft need?\u003c\/strong\u003e That is not published for this part. Count the plates in each arm joint you open, note which shape came from where, and order one set for each pair of plates you are replacing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMy arm feels loose. Is it the friction plates?\u003c\/strong\u003e Possibly, but check the arm locking rotation shaft, the arm connector and the joint fasteners first; each of those produces play that new plates will not remove. Then compare the suspect arm's plates with those from a sound arm.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this the arm locking rotation shaft?\u003c\/strong\u003e No. The arm locking rotation shaft is a separate part sold as its own pack. This set is the two flat plates only.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eI found a plate missing after an earlier repair. Do I need the whole set?\u003c\/strong\u003e Replacing both plates from one set keeps the joint at a single state of wear and makes sure each position gets the correct shape. If the remaining plate is sound you can keep it as a spare.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat are the plates made of, and how thick are they?\u003c\/strong\u003e Material, thickness and dimensions are not published for this part. Compare the new plates with the ones you removed by outline, hole size and flatness.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre screws or washers included?\u003c\/strong\u003e No. The set is the two plates only. Reuse sound original fasteners, or replace any with damaged threads or heads separately.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill new plates fix a bent arm?\u003c\/strong\u003e No. The plates are a contact layer in the joint; they do not straighten an arm or close up a cracked arm connector. Those parts need attention first.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it fit the T50 or T25?\u003c\/strong\u003e It is listed only for the T40 and T20P. Do not fit it to other Agras models on the strength of a similar shape.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I fit them myself?\u003c\/strong\u003e Most operators can. Photograph each plate in place before removal, keep parts grouped by position, match each new plate by outline and hole, tighten evenly without distorting the plates, and test the arm fold by hand before flying.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs there a service interval?\u003c\/strong\u003e No. Replace the plates when they are cracked, torn, distorted, worn at the hole or missing.
