{"product_id":"dji-agras-t40-oem-centrifugal-spray-rod-kit","title":"DJI Agras T40 OEM Centrifugal Spray Rod Kit","description":"\u003cp\u003eThe DJI Agras T40 OEM Centrifugal Spray Rod Kit is the complete four-piece spray rod set for a centrifugal sprinkler position on the spraying system: the centrifugal spray rod itself, the spray rod adaptive shaft, the spray rod fixing nut and the spray rod quick-release sleeve. It is identified for the DJI Agras T40 and T20P. The rod is the cranked arm that carries the centrifugal sprinkler out from the airframe and sets where it sits; the three smaller pieces are the joint hardware that completes the rod's connection and lets it be secured and released. The kit exists for the repair where the arm and its joint were damaged together, or where the joint pieces have worn to the point that a new arm alone would go back onto tired hardware. Operators search for it as a T40 spray rod kit, T40 sprinkler arm kit, T20P spray rod set, T40 spray rod quick-release sleeve, or Agras centrifugal spray rod with nut and shaft.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🇺🇸 U.S.A.

On the T40 and T20P the spray rod is the part that carries the sprinkler out from the airframe and holds it there. The kit is that rod plus the three pieces that complete its joint.\u003c\/p\u003e\n\u003cp\u003eEach piece is recognisable on the bench:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe centrifugal spray rod\u003c\/strong\u003e is a cranked, moulded black arm. One end is a rectangular socket with a small rectangular window in its wall; the other end is a broad, round foot with slots in its side. The long section between them is a flat-sided beam.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe spray rod adaptive shaft\u003c\/strong\u003e is a black slotted adapter. One end carries a crown of slotted fingers, the middle carries a flange with ribs below it, and the other end is a plain round spigot.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe spray rod fixing nut\u003c\/strong\u003e is the smaller of the two knurled pieces, with fine vertical knurling around its outside.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThe spray rod quick-release sleeve\u003c\/strong\u003e is the larger knurled piece, with broader ribs; it is the piece designed to be gripped by hand.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eAs the part designations say, the adaptive shaft adapts the rod's joint, the fixing nut secures it, and the quick-release sleeve lets the connection be released and refitted without tools. Exactly how the three pieces stack on your aircraft is easiest to confirm from a photograph of the old set taken before it comes apart.\u003c\/p\u003e\n\u003cp\u003eThe rod is one of the most exposed parts of the spraying system. It sits low on the aircraft, takes the leverage of the sprinkler's weight on a hard landing, meets crop canopy on low passes, gets caught in transport, and lives in chemical mist and wash water. The joint pieces share all of that, and add their own wear: a sleeve and a nut are threaded and gripped every time the sprinkler comes off for cleaning.\u003c\/p\u003e\n\u003cp\u003eTypical reasons for replacing the whole kit are an impact that cracked or bent the rod and also split or distorted the nut or sleeve, a joint that no longer locks firmly after many cleaning cycles, chemical residue that has seized or swollen the threaded pieces, or a crash repair where the old joint hardware went missing.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\n\u003cp\u003eThe kit's engineering role is to hold a centrifugal sprinkler at a fixed position and attitude relative to the airframe, and to do it through a joint that can be taken apart for service and put back together the same way every time.\u003c\/p\u003e\n\u003cp\u003eThe two jobs are split between the pieces:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePosition and angle\u003c\/strong\u003e — the rod carries the sprinkler out from the airframe and sets the line along which it sprays\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMatching the other side\u003c\/strong\u003e — a correct rod puts its sprinkler where the sprinkler on the opposite side mirrors it\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA secure joint\u003c\/strong\u003e — the adaptive shaft and fixing nut hold the rod's connection tight against vibration and downwash\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA serviceable joint\u003c\/strong\u003e — the quick-release sleeve lets the connection be undone for cleaning or replacement and refitted by hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoad path\u003c\/strong\u003e — the rod and its joint carry the sprinkler's weight and vibration into the airframe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eNone of the four pieces generates the spray, meters the liquid or controls the sprinkler. Those jobs belong to the pump, the flow meter, the solenoid valve and the centrifugal motor. The kit controls where the sprinkler is and whether it stays there.\u003c\/p\u003e\n\u003cp\u003eThat is why problems with it show up as coverage and vibration problems rather than as errors on the remote controller. The aircraft cannot tell that a sprinkler has dropped a few degrees, or that a joint has started to move. The motor spins, the valve opens, and the spray still lands somewhere it should not.\u003c\/p\u003e\n\u003cp\u003eWhat the kit does not do matters too:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIt does not fix a motor that grinds, stalls or will not start\u003c\/li\u003e\n\u003cli\u003eIt does not fix cracked, warped or residue-caked spinner disks\u003c\/li\u003e\n\u003cli\u003eIt does not fix low or no flow, which belongs to the pump, hoses, filters and solenoid valve\u003c\/li\u003e\n\u003cli\u003eIt does not fix a damaged sprinkler cable or connector\u003c\/li\u003e\n\u003cli\u003eIt does not straighten a bent airframe arm or landing gear mount that the rod is fixed to\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003chr\u003e\n\u003ch2\u003e🔍 Diagnosis — decide whether the arm failed, the joint failed, or both\u003c\/h2\u003e\n\u003cp\u003eA spray rod position can fail in two different places, and they call for different parts. The arm can be bent or cracked, which moves the sprinkler. The joint can be worn, loose or damaged, which lets the sprinkler move. Working out which one failed is the whole diagnosis, because it decides whether the rod alone, the joint pieces alone, or this complete kit is the repair.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eArm faults\u003c\/strong\u003e — the rod itself has moved the sprinkler:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe sprinkler sits lower, further out, further in, or tilted compared with the sprinkler on the other side\u003c\/li\u003e\n\u003cli\u003eThe rod shows a bend when you sight along its length\u003c\/li\u003e\n\u003cli\u003eThere is a crack in the beam, at the bend, at the socket end or around the round foot\u003c\/li\u003e\n\u003cli\u003eCoverage is heavier on one side of the swath, or there is a stripe at one edge, with flow that checks out\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eJoint faults\u003c\/strong\u003e — the connection lets the sprinkler move:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eThe sprinkler can be rocked or turned by hand at the joint, while the rod itself is straight\u003c\/li\u003e\n\u003cli\u003eThe fixing nut will not tighten firmly, spins without drawing up, or will not start on its thread\u003c\/li\u003e\n\u003cli\u003eThe quick-release sleeve will not lock, slips under hand pressure, or is cracked or split\u003c\/li\u003e\n\u003cli\u003eThe adaptive shaft's slotted fingers are broken, splayed or chewed\u003c\/li\u003e\n\u003cli\u003eOne sprinkler vibrates or chatters more than its partner, and the vibration changes when you press on the joint\u003c\/li\u003e\n\u003cli\u003eResidue has seized the nut or sleeve so the joint cannot be undone for cleaning without force\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eHow to tell them apart in a few minutes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompare both sides first.\u003c\/strong\u003e With the aircraft level, look from behind and from the side.

The arm can move the sprinkler, or the joint can let it move. Both show up as the same thing in the field: a swath that is not even, a sprinkler that shakes, spray in the wrong place. They are not the same repair.\u003c\/p\u003e\n\u003cp\u003eThat is the reason this kit exists alongside the rod sold on its own and the nut and shaft pair. The rod alone restores the arm. The pair restores two of the joint pieces. Neither one restores the whole position. When an impact has bent the arm and split the sleeve, or when a season of chemical work has worn the threads and knurling that hold the sprinkler tight, fitting a new arm onto the old joint leaves half the fault in place, and the sprinkler goes on moving.\u003c\/p\u003e\n\u003cp\u003eThe kit replaces all four pieces in one fit: the arm that sets where the sprinkler sits, and the shaft, nut and sleeve that decide whether it stays there. Every surface that meets another piece is new, so nothing new is being asked to seal or grip against something worn.\u003c\/p\u003e\n\u003cp\u003eEqually, if the diagnosis shows only one half failed, the kit is more than the repair needs. A straight rod with a worn joint wants joint pieces. A bent rod on a joint that still locks firmly wants a rod. Settling which half failed takes a few minutes with the aircraft on a level surface and the joint in your hand, and it is the check that makes sure the right pieces arrive first time.\u003c\/p\u003e\n\u003cp\u003eWhen both halves are suspect, or the old joint pieces are already off the aircraft and you cannot vouch for them, the full kit is the repair that leaves no doubt about any part of the position.\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 kit is mechanical and has no electrical parts.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I fit it myself?\u003c\/strong\u003e Most operators can. Drain and rinse first, photograph the joint and the hose and cable routing, check the airframe mount, start each thread by hand, and test both sprinklers with clean water afterwards.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs there a service interval?\u003c\/strong\u003e No published interval. Replace the pieces when the rod is bent or cracked, or when the joint no longer locks firmly, and rinse the joint after every chemical day.\u003c\/p\u003e","brand":"Ares Acres","offers":[{"title":"DJI T40","offer_id":68077809566016,"sku":null,"price":149.99,"currency_code":"USD","in_stock":true},{"title":"DJI T20P","offer_id":68077809598784,"sku":null,"price":149.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0923\/0159\/0848\/files\/dji-agras-t40-oem-centrifugal-spray-rod-kit-1.png?v=1794316503","url":"https:\/\/aresacres.com\/pt\/products\/dji-agras-t40-oem-centrifugal-spray-rod-kit","provider":"Ares Acres","version":"1.0","type":"link"}
