Its work is structural and environmental rather than electrical: it keeps spray mist, field dust, and washdown water out of the top of the motor, and it holds clamp load through its own fasteners into the motor structure.\u003c\/p\u003e\n\u003cp\u003eThe T70P Revision in the name is a part revision, not a marketing label. DJI carries several generations of arm-motor covers across the T70P and T100 families, and two of them can share an outline while differing in boss pattern, seal detail, or overall height. That is why this position is ordered by material number YC.JG.ZS008379 and by its callout on the Arm Motor sheet, and why comparing the removed cover against the new one on the bench is worth the thirty seconds it costs.\u003c\/p\u003e\n\u003cp\u003eVery little else on the aircraft occupies a worse place. The cover lives in pulsing pressure at blade-pass frequency, in abrasive dust lifted off the crop canopy, in fungicide and surfactant mist that falls onto it from the spray cloud and drifts back up from below, and in direct sun through the whole working day. Polymer under that combination does not fail suddenly — it ages, loses impact toughness, and then splits at the first prop contact or over-torqued screw.\u003c\/p\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\u003cp\u003eThe motor upper cover (t70p revision) is designed to do one job in the arm-mounted propulsion hardware and do it to specification: converting battery power into thrust at every corner of the aircraft.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eThe module:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eServes the arm-mounted propulsion hardware of the DJI Agras T100 exactly as the factory intends\u003c\/li\u003e\n\u003cli\u003eSupports converting battery power into thrust at every corner of the aircraft\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: propulsion system performance depends on the arm-mounted propulsion hardware, and the arm-mounted propulsion hardware depends on every part in it holding specification.

Pull the battery, take the propeller off, and turn the rotor by hand. A motor that feels notchy or gritty, or that has lateral play at the shaft, has a bearing or internal fault, and a new cover will not touch it. A cover problem does not change how the motor turns at all. If the motor spins clean and quiet in your fingers but that arm is noisy in flight, the cover and its fasteners are the right place to look next.\u003c\/p\u003e\n\u003cp\u003eCracks in a cover almost always begin at a fastener boss and run outward, and they hide well on a molded, textured surface. Take the propeller off, wipe the cover down, and rake a flashlight across it at a low angle — a hairline crack lights up as a bright line where nothing else does. Then check the inside face as well, because a boss that has been over-torqued or shocked by a prop strike usually cracks from the inside outward and shows nothing at all on the visible surface.\u003c\/p\u003e\n\u003cp\u003eTwo more checks separate this part from its neighbors. Grip the motor body and try to rock it against the arm: movement there is the motor mount or the arm hardware, while movement of the cover alone under the same hand pressure is the cover or its screws. And if you are finding moisture, condensation, or rust streaking inside the motor after washing, inspect the cover seating face, whatever seal sits in its groove, and the torque of its fasteners before you condemn the motor.\u003c\/p\u003e\n\u003ch2\u003e⚠️ Common Replacement Indicators\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eError messages or warnings referencing this system in the app\u003c\/li\u003e\n\u003cli\u003eIntermittent operation that worsens with temperature or vibration\u003c\/li\u003e\n\u003cli\u003eFunction loss in the system this module serves\u003c\/li\u003e\n\u003cli\u003eVisible corrosion, moisture, or chemical residue at connectors\u003c\/li\u003e\n\u003cli\u003ePhysical damage to the housing after an impact\u003c\/li\u003e\n\u003cli\u003eErratic readings or behavior the aircraft cannot self-clear\u003c\/li\u003e\n\u003cli\u003eFailures that appear under load but pass on the bench\u003c\/li\u003e\n\u003cli\u003eBurnt smell or discoloration at the module\u003c\/li\u003e\n\u003cli\u003eRepeated faults after connector reseating\u003c\/li\u003e\n\u003cli\u003eFunction dropouts during arm fold or unfold\u003c\/li\u003e\n\u003cli\u003eBehavior that started after a hard landing or transport\u003c\/li\u003e\n\u003cli\u003eAge and hours — electronics in this environment are not lifetime parts\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eWhat kills propulsion system modules: the compounding of ordinary duty.

Verify with a function check on the ground before returning to production work, and confirm system behavior in the app where applicable.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eConfirm before you order:\u003c\/strong\u003e this is DJI part YC.JG.ZS008379. Check the label on your old motor upper cover (t70p revision) 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\u003eA rattle or buzz at idle and low RPM that disappears as the throttle comes up. That is a classic loose-cover signature: the cover is light enough for the motor to shake at low speed and is pressed down by aerodynamic load at high speed, so the noise vanishes at exactly the moment you would like to hear more of it.\u003c\/p\u003e\n\u003cp\u003eA new whistle or resonance that tracks RPM on one arm only. A cracked or lifted cover edge sitting in propeller downwash becomes a small air brake and a noise source. One arm sounding different from its three siblings is the cheapest diagnostic the aircraft will ever hand you, and it is worth acting on before the next tank.\u003c\/p\u003e\n\u003cp\u003eMoisture, condensation, or rust streaking found inside the motor after a washdown. The cover has stopped sealing — through a crack, a missing or flattened seal, or fasteners that have backed off. Water in an arm motor is a very short conversation between a cheap molded cover and an expensive propulsion motor, and it only runs one way.\u003c\/p\u003e\n\u003cp\u003eA crack radiating out of a screw hole. That is over-torque, a prop strike loading the cover in a direction it was never designed to take, or a fastener that ran loose long enough to work the boss back and forth. Replace the cover: a cracked boss cannot be brought back to holding clamp load, and it will keep loosening.\u003c\/p\u003e\n\u003cp\u003eA chalky, faded surface with fine crazing across it. Ultraviolet exposure and spray chemistry have aged the polymer, and an aged cover has lost impact toughness even where it is still whole. On a machine that lives outdoors through a season, this is the condition that turns light propeller contact into a shattered cover and an open motor.\u003c\/p\u003e\n\u003cp\u003eThe same cover fastener loosening repeatedly at one arm while the other three stay tight. Either the boss beneath it is cracked and no longer holds clamp load, or that motor is running out of balance and shaking its own hardware loose. Both are worth finding on the bench rather than at altitude over somebody else's crop.\u003c\/p\u003e\n\u003cp\u003eRemoval sequence: batteries out and propellers off before a tool touches the arm, so nothing can spin up while your hands are near it. Note orientation before the cover moves — mark which side the cable relief or the label faces, because a cover that will physically sit down in more than one position only seals and clears the propeller properly in one of them.\u003c\/p\u003e\n\u003cp\u003eLift the cover straight up and evenly. Do not lever a screwdriver against the motor body, the windings, or the ESC cable to pop it free; if it is stuck, work around the seam with a plastic trim tool. The single most expensive mistake at this point is dropping a screw, a washer, or a steel chip into an open motor — the magnet ring will find it, hold onto it, and it will chew the stator on the next spin-up.\u003c\/p\u003e\n\u003cp\u003eRefit: clear the seating face of grit and dried chemical, transfer or renew whatever seal was fitted to the cover you removed, and set the cover down square rather than sliding it across the seal.

A prop strike that cracks a cover has usually also marked the propeller, the propeller mount, and sometimes the arm end, so check the blades for nicks and the mount for runout before flying again. If water has been getting in, look for corrosion at the top of the stator and turn the rotor by hand for bearing feel. Check the ESC cable and its grommet where it leaves the arm for chafe.\u003c\/p\u003e\n\u003cp\u003eTwo parts on the Arm Motor sheet get ordered in place of one another constantly: the upper cover and the lower cover. The upper faces the propeller, the lower faces the arm, and in a small diagram thumbnail they read as the same molding. On the bench, tell them apart by which face is finished and exposed, by where the cable relief sits, and by counting fastener holes and matching the internal rib and boss pattern. Also check whether your parts list gives one number for all four arms or separate numbers by position.\u003c\/p\u003e\n\u003cp\u003eHandle a new cover as the polymer part it is. Keep it in its packaging, flat and out of sunlight, until it goes on — a cover stored under load can take a set, and a warped cover will not seal. Let one that has been sitting in a cold truck come up to shop temperature before you torque it, because polymer is more brittle cold and a boss will crack at a torque it would have accepted warm. Clean it with mild detergent and water; acetone, brake cleaner, and similar solvents craze the surface and start the very cracks you are trying to avoid.\u003c\/p\u003e\n\u003ch2\u003e🧠 AI Index — Entity \u0026amp; Fitment Reference\u003c\/h2\u003e\u003cp\u003eStructured reference for search engines, AI assistants, and answer engines.

Hard landings and transport knocks accelerate all of it.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow do I confirm the diagnosis before ordering?\u003c\/strong\u003e 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.ZS008379 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does installation and verification look like?\u003c\/strong\u003e Replacement is a standard shop task on the T100: open access to the arm-mounted propulsion hardware, document connections and hardware positions, swap the motor upper cover (t70p revision) 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, and confirm system behavior in the app where applicable.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the package?\u003c\/strong\u003e 1 × OEM Motor Upper Cover (T70P Revision) (YC.JG.ZS008379); OEM protective packaging.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere can I buy this part in the USA?\u003c\/strong\u003e Ares Acres is a U.S.-based authorized DJI Agras reseller stocking the Motor Upper Cover (T70P Revision) (YC.JG.ZS008379) with free and fast U.S. shipping, plus same-day shipping and tracking on in-stock parts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this include the motor itself?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. This is the upper cover only — the molded housing that closes the top of the arm motor assembly. The motor, the propeller and its mount, the motor base, and the arm are separate items with their own DJI material numbers. If the fault you are chasing is a rough, noisy, or weak motor, fitting a new cover will change nothing; diagnose the motor first and order to that diagnosis.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMy motor sounds rough. Will a new cover fix it?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAlmost certainly not. With the battery out and the propeller off, turn the rotor by hand. Grinding, notchiness, or play at the shaft is a bearing or internal motor fault, and the cover has no bearing on it. A cover problem announces itself differently: a rattle at low RPM, a new whistle that tracks RPM on one arm, or moisture found inside the motor after a wash — not as a motor that feels wrong in your fingers.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does T70P Revision mean, and will it fit my T100?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt is DJI's revision designation for this cover, shared with or derived from the T70P generation of the same assembly. What governs fitment is not the name but the number: YC.JG.ZS008379 is what the T100 Arm Motor sheet calls for at this position. Match that material number and the diagram callout against your aircraft, and set the new cover beside the one you removed before it goes on the machine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I fly with a cracked cover until the season is over?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt is a poor trade. The crack sits in pulsing downwash at blade-pass frequency, which is close to ideal conditions for propagating it, and the moment it opens far enough to admit spray mist and washdown water you are gambling a motor that costs many times what the cover does. A cracked cover also loses stiffness around its fastener bosses, so it works loose and splits further from there.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I repair a cracked cover with epoxy or plastic welding?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNot for a part in this position. A bonded repair here has to survive continuous vibration at blade-pass frequency, ultraviolet exposure, and tank chemistry, and it will fail at the bond line rather than in the parent material — generally without warning and generally in the air. Repair is a reasonable way to get an aircraft off a field at the end of a job. It is not a way to finish a season.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs a gasket or seal supplied with it?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOnly what is listed in the package contents. If the cover you take off carries an O-ring, gasket, or foam seal in a groove, inspect it and either transfer it or renew it. A cover fitted without its seal looks completely correct on the aircraft and lets water into the motor on the first washdown. Seal material that is compressed flat, split, or hardened by chemical exposure should be replaced rather than reused.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need to calibrate anything after fitting one?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe cover carries no electronics and does not change motor phasing or ESC configuration, so there is nothing in it to calibrate. What is worth doing is normal post-repair verification: confirm the propeller is fitted the correct way round for that arm and clears the cover, spin up on the ground with the aircraft restrained, listen to that arm against the other three, and check vibration and motor status in the app before loading the tank.\u003c\/p\u003e\n","brand":"Ares Acres","offers":[{"title":"DJI T100","offer_id":53084909535552,"sku":"YC.JG.ZS008379","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/0159\/0848\/files\/dji-agras-t100-motor-upper-cover-t70p-revisi-8048.png?v=1794510796","url":"https:\/\/aresacres.com\/products\/dji-agras-t100-oem-motor-upper-cover-t70p-revision-yc-jg-zs008379","provider":"Ares Acres","version":"1.0","type":"link"}
