{"product_id":"dji-agras-t40-oem-spreading-flange","title":"DJI Agras T40 OEM Spreading Flange","description":"\u003cp\u003eThe DJI Agras T40 OEM Spreading Flange is a small, black moulded hub-and-plate coupling from the aircraft's granular spreading system. It is a round, flat plate with a raised cylindrical hub at its centre; the hub carries a flatted, D-shaped bore that takes drive from a shaft with a matching flat, and the underside of the plate carries short pegs that key the flange to the part it turns. A moulded A10 mark sits on the face of the plate. It belongs to the spreading system, not to the spray, power or flight-control systems, and it is identified for the DJI Agras T40 and T20P. Operators usually find it while searching for a T40 spreader flange, a T20P spreading system flange, a spreader drive hub, or the reason a spreader runs but throws an uneven pattern. 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 sits on a shaft in the spreading system and passes that shaft's rotation on to the part it carries. It is small, it is usually buried in granular residue, and on a working aircraft it is easy to look straight past.\u003c\/p\u003e\n\u003cp\u003eIts shape tells you how it works. The flange has four working features, all visible in the product images:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe round plate\u003c\/strong\u003e — a flat, circular disc that forms the base of the flange and gives it a wide, square face to seat against the part it drives\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe raised hub\u003c\/strong\u003e — a cylindrical boss rising from the centre of the plate, with a chamfered top edge, a step near its base and small side bosses on its wall\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe flatted bore\u003c\/strong\u003e — the hole through the hub is not round; it has a flat, giving it a D-shaped profile that locks the flange to a shaft with a matching flat so the two turn together\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe pegs\u003c\/strong\u003e — short moulded pegs standing proud of the underside of the plate, which key the flange to the part it turns so that part cannot slip around the plate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe moulded A10 mark on the face of the plate is an identification mark on the moulding. It is useful when comparing the new flange with the old one; it is not a DJI material number and should not be ordered against as one.\u003c\/p\u003e\n\u003cp\u003eTwo interfaces do all the work: the flat inside the bore and the pegs under the plate. Everything the spreader does downstream of this shaft depends on both of them holding their shape.\u003c\/p\u003e\n\u003cp\u003eOver a working season the flange sees:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eStart-up and shut-down torque on every spreading run, carried through one flat in the bore\u003c\/li\u003e\n\u003cli\u003eAbrasive granular product — fertiliser, seed and pellet dust — working its way between the bore and the shaft\u003c\/li\u003e\n\u003cli\u003eCorrosive fertiliser residue left standing on the hub and plate between jobs\u003c\/li\u003e\n\u003cli\u003eHard material jams that load the pegs and the bore at the same instant\u003c\/li\u003e\n\u003cli\u003eRepeated removal and refitting during cleaning and spreader service\u003c\/li\u003e\n\u003cli\u003eWash water and pressure washing at the end of each day\u003c\/li\u003e\n\u003cli\u003eHeat in the sun and on the trailer between flights\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFlanges in this position come out for three reasons: pegs sheared or rounded by a jam, a plate cracked by an impact or a tool during removal, or a bore whose flat has worn round so the shaft turns inside it. The last of those leaves the flange looking intact, and it is the failure this part's diagnosis is built around.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\n\u003cp\u003eThe flange's engineering role is torque transfer and location. The flatted bore takes rotation from the shaft without slipping; the plate gives the driven part a flat, square seat so it runs true; the pegs lock that part to the plate so the two turn as one.\u003c\/p\u003e\n\u003cp\u003eIn the spreading system it:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCouples the drive shaft to the part it turns, through the flat in the bore\u003c\/li\u003e\n\u003cli\u003eKeys that part to the plate through the pegs on the underside\u003c\/li\u003e\n\u003cli\u003eSets the seating face, so the driven part runs square to the shaft rather than wobbling\u003c\/li\u003e\n\u003cli\u003eKeeps the driven part at a fixed height on the shaft through the hub and its step\u003c\/li\u003e\n\u003cli\u003eSpreads the drive load across a wide plate rather than a single point\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eWhat it does not do matters as much:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIt is not the motor; it has no windings, bearings or electrical connection\u003c\/li\u003e\n\u003cli\u003eIt does not meter product; the hopper outlet and metering parts decide how much material flows\u003c\/li\u003e\n\u003cli\u003eIt is not the spinning disc or a vane; it carries and drives, it does not throw material itself\u003c\/li\u003e\n\u003cli\u003eIt carries no wiring and no sensor, so it never raises its own error\u003c\/li\u003e\n\u003cli\u003eIt does not seal anything; residue reaches the bore whether the flange is new or worn\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThat division of labour is why a worn flange is so easy to miss. The motor still runs, the controller still reports the motor turning, and the only evidence is in how the product leaves the aircraft.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🔍 Diagnosis — the shaft turns, so check that the flange turns with it\u003c\/h2\u003e\n\u003cp\u003eA spreading flange rarely fails by breaking in half. It fails at the flat. The flat in the bore is a small area carrying all the drive torque, and abrasive granular dust works into it every flight. Over a season the flat can wear, round off or crack at its corners, and the bore slowly stops gripping the shaft.\u003c\/p\u003e\n\u003cp\u003eWhen that happens, nothing looks wrong. The flange is in one piece. The motor spins. The shaft turns. But under load — a full hopper, a heavy product, a start-up — the shaft turns a little inside the flange before it catches, or slips outright for a moment, and the part the flange drives lags behind the shaft.\u003c\/p\u003e\n\u003cp\u003eThat lag shows up downstream, not at the flange. The pattern narrows or goes uneven. One side of the swath gets less product. Coverage looks patchy on the ground. Every one of those symptoms points first at the motor, the metering setting or the calibration, and a worn flange can survive a motor change, a recalibration and a cleaned hopper without anyone looking at it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSigns the flange is slipping or loose:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eSpread pattern narrower or less even than the same product and settings produced before\u003c\/li\u003e\n\u003cli\u003eA ticking, clicking or knocking from the spreader at start-up or when the hopper is full\u003c\/li\u003e\n\u003cli\u003eThe driven part can be rocked back and forth by hand while the shaft is held still\u003c\/li\u003e\n\u003cli\u003ePolished, shiny wear on the flat of the shaft or inside the bore\u003c\/li\u003e\n\u003cli\u003eFine plastic dust, or a black smear, around the hub after a job\u003c\/li\u003e\n\u003cli\u003eThe driven part sitting tilted or wobbling as it turns\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBefore condemning the flange, rule out what imitates it:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe spreading motor\u003c\/strong\u003e — if the shaft itself is slow, stalls or stops, the motor or its drive is the problem, not the flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe metering parts and hopper outlet\u003c\/strong\u003e — a partly blocked or caked outlet starves the spreader and narrows the pattern on its own\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe spinning disc or vanes\u003c\/strong\u003e — a cracked, chipped or bent disc throws an uneven pattern even on a perfect flange\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMissing or loose retaining hardware\u003c\/strong\u003e — a flange that has lifted on its shaft can rock even when the bore is good\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibration and settings\u003c\/strong\u003e — product changes and settings changes alter the pattern without any part wearing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eUse a paint mark as your instrument.\u003c\/strong\u003e With the aircraft powered down and the battery out, clean the hub and shaft end, then draw one straight line across the shaft end, the hub and the plate. Hold the shaft still and try to turn the driven part by hand in each direction. If the line breaks — the flange moves on the shaft, or the driven part moves on the flange — you have found the slip. A good flange and shaft show no visible movement at the mark.\u003c\/p\u003e\n\u003cp\u003eThen look at the two wear points directly. Pull the flange and check the flat in the bore: its edges should be crisp and straight, not rounded or polished. Turn it over and check the pegs: each one should stand full height, square and uncracked. Do those checks first, while the spreader is already apart and that information is still cheap. If the bore flat is rounded, a peg is sheared or worn, or the plate is cracked, replace the flange rather than refitting it.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e⚠️ Common Replacement Indicators\u003c\/h2\u003e\n\u003cp\u003eReplace the spreading flange when inspection confirms one of these:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFree play between the flatted bore and the shaft that a paint mark shows as movement\u003c\/li\u003e\n\u003cli\u003eA flat in the bore that is rounded, polished or cracked at its corners\u003c\/li\u003e\n\u003cli\u003eA peg that is sheared off, cracked at its root or worn shorter than the others\u003c\/li\u003e\n\u003cli\u003eA crack anywhere in the plate, or running from the hub into the plate\u003c\/li\u003e\n\u003cli\u003eA crack or split in the hub wall, at the side bosses or at the step near the base\u003c\/li\u003e\n\u003cli\u003eA plate that is bent, warped or no longer sits flat against the part it drives\u003c\/li\u003e\n\u003cli\u003eChemical attack or chalky, softened surfaces from fertiliser residue\u003c\/li\u003e\n\u003cli\u003ePrevious repairs with adhesive or filler at the bore, hub or pegs\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eInspect these first, because they produce similar symptoms:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe spreading motor and the flat on its shaft\u003c\/li\u003e\n\u003cli\u003eThe spinning disc and its vanes\u003c\/li\u003e\n\u003cli\u003eThe hopper outlet and metering parts\u003c\/li\u003e\n\u003cli\u003eThe retaining hardware that holds the flange on its shaft\u003c\/li\u003e\n\u003cli\u003eSpreader calibration for the product in the hopper\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThere is no published service interval for this flange.

It raises no error, the motor still turns, and the flange itself stays in one piece. It simply stops passing on all of the turn it is given.\u003c\/p\u003e\n\u003cp\u003eThat is the whole case for checking it and replacing it when the bore flat has gone. A flange slipping on its shaft does not stop a job; it degrades the job. The swath narrows, coverage goes patchy, and the usual response is to change the settings, recalibrate, or suspect the motor. Each of those takes time on the aircraft and none of them fixes a bore that has worn round.\u003c\/p\u003e\n\u003cp\u003eUneven granular spreading is also expensive in a way that shows up later than the flight. Under-dosed strips and over-dosed strips appear in the crop weeks after the work, long after the aircraft has moved on to the next field.\u003c\/p\u003e\n\u003cp\u003eThe check is free. A paint line across shaft, hub and plate, and a hand on the driven part with the shaft held still, tells you whether the flange is still turning with the shaft. If it is, leave it and look elsewhere. If it is not, this is the part that puts the drive 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.

The usual failure is a bore flat that wears round.
