{"product_id":"dji-agras-t30-oem-reduction-gearbox-module","title":"DJI Agras T30 OEM Reduction Gearbox Module","description":"\u003cp\u003eThe DJI Agras T30 OEM Reduction Gearbox Module is the geared drive unit of the aircraft's granular spreading system. It is a black, cylindrical module built in stepped sections held together by screwed flanges, with a round black guard ring on spokes around its upper end, a long steel output shaft with a threaded tip running out through the centre of that ring, a short stub shaft at the opposite end, and two leads that leave through a black grommet plate: one ending in a small black connector and one, with blue, yellow and red wires, ending in a yellow-sealed connector. A reduction gearbox exists to turn fast, light rotation into slower rotation with more turning force, and this module delivers that slower rotation along its long output shaft to the spreading mechanism. It belongs to the spreading system, not to the spray, power or flight-control systems, and it is identified for the DJI Agras T30 and T10. Operators usually reach it while searching for a T30 spreader gearbox, a T30 spreading motor gearbox, a T10 spreader drive, a bent T30 spreader shaft, or the reason a T30 spreader runs with a wobble, a grind or no output at all. 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.

A motor on its own spins fast with little turning force. A reduction gearbox sits between the drive and the work, slowing the rotation down and multiplying the force, so the mechanism on the end of the shaft keeps turning under load instead of stalling.\u003c\/p\u003e\n\u003cp\u003eThe module's features, all visible in the product images:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe gearbox body\u003c\/strong\u003e — a black cylinder built in stepped sections, the widest section in the middle, joined by flanges with screws around their edges\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe guard ring\u003c\/strong\u003e — a round black ring carried on spokes around the upper end of the body, the largest feature of the module\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe output shaft\u003c\/strong\u003e — a long, bright steel shaft that runs out through the centre of the guard ring and ends in a threaded tip\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe stub shaft\u003c\/strong\u003e — a short shaft with a flat at the opposite end of the body\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe grommet plate\u003c\/strong\u003e — a black rectangular plate where the leads leave the module\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe two leads\u003c\/strong\u003e — one ending in a small black connector, one with blue, yellow and red wires ending in a yellow-sealed connector\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe module is not a passive bracket.

Everything the module does arrives at the work through one long, slender steel shaft. The gear train can be perfect and the module can still be wrong, if the shaft that carries its output no longer runs straight.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🔍 Diagnosis — a bent output shaft still turns, and that is exactly why it gets missed\u003c\/h2\u003e\n\u003cp\u003eWhen a spreader starts to wobble, grind or wear out the parts on the end of its shaft, the instinct is to listen for a failed gear or a failing drive. Those faults happen. But the commonest damage to a module with a long, slender output shaft is simpler and quieter: the shaft has been bent. A knock during fitting, a heavy landing with the spreading system on, or a jam that stopped the mechanism while the drive kept pushing, and the shaft is no longer on its own axis.\u003c\/p\u003e\n\u003cp\u003eA bent shaft does not stop the spreader. That is the trap. The module still powers up, the gears still turn, the shaft still rotates and the mechanism on the end of it still moves. Nothing reports a fault. What changes is that the far end of the shaft now traces a small circle instead of spinning on a point. Every turn pushes sideways where the shaft leaves the gearbox and rocks whatever is fitted to the tip. The spreader runs, and it runs rough.\u003c\/p\u003e\n\u003cp\u003eThe longer the shaft, the more a small bend near the body shows at the tip. That makes the tip the instrument: watch it, not the body.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSigns the reduction gearbox module has failed:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe threaded tip of the output shaft visibly wobbles or traces a circle when the shaft turns\u003c\/li\u003e\n\u003cli\u003eVibration or a rhythmic knock from the spreader that rises and falls with the shaft speed\u003c\/li\u003e\n\u003cli\u003eGrinding, clicking or a rough feel from inside the gearbox when the shaft is turned\u003c\/li\u003e\n\u003cli\u003eThe drive is heard running but the output shaft does not turn, or slips under load\u003c\/li\u003e\n\u003cli\u003ePlay in the output shaft when it is rocked side to side at the tip\u003c\/li\u003e\n\u003cli\u003eUneven wear, scoring or rubbing marks on the parts mounted on or around the shaft\u003c\/li\u003e\n\u003cli\u003eA cracked guard ring, a broken spoke or a cracked body flange\u003c\/li\u003e\n\u003cli\u003eDamaged leads at the grommet plate, or a corroded, cracked or loose connector\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eBefore condemning the gearbox, rule out what imitates it:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePacked or caked product\u003c\/strong\u003e — material jammed around the mechanism makes a healthy gearbox labour, click or stall\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe part on the end of the shaft\u003c\/strong\u003e — a loose, cracked or out-of-balance part fitted to the tip makes a straight shaft look as if it wobbles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe mounting\u003c\/strong\u003e — loose fixing screws let the whole module rock in its seat, which feels like shaft play\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe hopper\u003c\/strong\u003e — a bridged or blocked hopper starves the spreader whatever the gearbox does\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSettings and calibration\u003c\/strong\u003e — a product or settings change alters delivery with every part healthy\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe signal cable and connectors\u003c\/strong\u003e — a module that is not receiving its command looks dead without being dead\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eUse the shaft tip as your instrument.\u003c\/strong\u003e With the aircraft powered down and the battery out, empty and remove the hopper, wash out the spreader and remove whatever is fitted to the tip of the output shaft. Turn the shaft slowly by hand while you watch the threaded tip against a fixed edge, a ruler held close or a straight line on the frame behind it. A straight shaft turns on a point. A bent one swings its tip around a small circle, and the gap to your reference edge opens and closes once per turn. Then hold the tip and rock it gently side to side: any knock or clearance is play at the gearbox end.\u003c\/p\u003e\n\u003cp\u003eDo that check first.

A small bend close to the gearbox becomes a visible circle at the tip, and every turn of that circle pushes sideways where the shaft leaves the body and rocks whatever is fitted to the end. The shaft still turns, so the spreader still works. It simply wears itself out while it does.\u003c\/p\u003e\n\u003cp\u003eThat is the whole case for this module. A gearbox with a bent shaft is not a part that might fail later; it has already failed, because it no longer holds its output on its own axis. Straightening a steel shaft by hand does not restore that, and a part that still turns is not the same as a part that is still right.\u003c\/p\u003e\n\u003cp\u003eIt is also the case against replacing the module too early. A loose part on the tip, loose mounting screws or packed product can all look and sound like a gearbox fault. Remove the part on the tip, spin the shaft by hand and watch it against a straight edge. If it turns on a point and rocks with no play, the gearbox is fine.\u003c\/p\u003e\n\u003cp\u003eWhen the tip swings a circle, the shaft has play at the body, or the gear train grinds with the mechanism clean, nothing else on the spreader will fix it. The module is the part that turns drive into steady, true rotation, and it is the part that puts the spreader back on its axis.\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.
