{"product_id":"dji-agras-t40-oem-centrifugal-spray-rod","title":"DJI Agras T40 OEM Centrifugal Spray Rod","description":"\u003cp\u003eThe DJI Agras T40 OEM Centrifugal Spray Rod is the rod that carries a centrifugal sprinkler out from the airframe and holds it in its working position on the spraying system. It is identified for the DJI Agras T40 and T20P. The rod has no motor, no valve and no electronics of its own; its whole job is location. It decides where the sprinkler sits relative to the aircraft, which way the sprinkler faces, and how squarely its spinning disks meet the spray path. Operators search for it as a T40 spray rod, T40 sprinkler arm, T20P spray rod or Agras centrifugal nozzle arm, and usually after a landing, a canopy strike or a transport knock has left one side looking not quite like the other.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e🇺🇸 U.S.A.

It throws liquid off the edges of spinning disks, and the shape of the spray it produces depends on where those disks are and how they are angled. The spray rod is the part that puts them there.\u003c\/p\u003e\n\u003cp\u003eOn the T40 and T20P the rod is the link between the airframe and a centrifugal sprinkler. One end is fixed to the aircraft; the other end carries the sprinkler. Whatever liquid line and cable feed that sprinkler on your aircraft follow the same route and have to be freed before the rod can come off.\u003c\/p\u003e\n\u003cp\u003eBecause it reaches out and down from the airframe, the rod is one of the most exposed parts on the spraying system:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIt is low on the aircraft and is among the first things to meet crop canopy on a low pass\u003c\/li\u003e\n\u003cli\u003eIt takes the leverage of the sprinkler's weight on a hard landing\u003c\/li\u003e\n\u003cli\u003eIt can be caught by a trailer edge, a strap or another aircraft during transport\u003c\/li\u003e\n\u003cli\u003eIt is knocked during cleaning, when the sprinkler and disks are being worked on\u003c\/li\u003e\n\u003cli\u003eIt lives in the same chemical mist and wash water as the sprinkler it carries\u003c\/li\u003e\n\u003cli\u003eIt sits in the rotor downwash for the whole of every spraying flight\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA spray rod rarely fails the way an electrical part fails. It does not stop working. It cracks, bends, or loosens at a mount, and it goes on carrying the sprinkler while it does. That is the reason it gets missed, and it is the subject of the diagnosis section below.\u003c\/p\u003e\n\u003cp\u003eTypical reasons for replacement are a visible crack, a bend after an impact, a mounting point that has worn or broken so the rod moves when pushed, or a rod that was damaged during a crash repair where the rest of the aircraft was put right.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\n\u003cp\u003eThe rod's engineering role is to hold a centrifugal sprinkler at a fixed position and attitude relative to the airframe, flight after flight, under vibration, downwash and liquid load.\u003c\/p\u003e\n\u003cp\u003eIn the spraying system it:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCarries the centrifugal sprinkler out from the airframe to its working position\u003c\/li\u003e\n\u003cli\u003eSets the angle at which the sprinkler's disks meet the spray path\u003c\/li\u003e\n\u003cli\u003eHolds the sprinkler on a line that matches the sprinkler on the other side of the aircraft\u003c\/li\u003e\n\u003cli\u003eGives the sprinkler's hose and cable a fixed route to follow\u003c\/li\u003e\n\u003cli\u003eTransfers the sprinkler's weight and vibration into the airframe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIt does not generate the spray, meter the liquid or control the sprinkler. Those jobs belong to the pump, the flow meter, the solenoid valve and the centrifugal motor. What the rod controls is geometry: where the spray starts from, and in which direction it is thrown.\u003c\/p\u003e\n\u003cp\u003eThat is why a damaged rod shows up as a coverage problem rather than as a fault on the remote controller. The aircraft has no way of knowing that one sprinkler is sitting a few degrees off where it should be. The motor spins, the valve opens, the flow is correct, and the spray still lands in the wrong place.\u003c\/p\u003e\n\u003cp\u003eWhat the rod 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 — a rod that still holds the sprinkler can still be holding it in the wrong place\u003c\/h2\u003e\n\u003cp\u003eA spray rod that has been bent in a landing or a canopy strike almost never falls off. The sprinkler is still attached, the disks still spin, nothing reports an error, and the aircraft goes back to work. The rod is still strong. It is just no longer accurate.\u003c\/p\u003e\n\u003cp\u003eThat is the whole problem with this part. Its strength and its geometry are two different things, and only one of them shows up in a quick inspection. A rod that has taken a few degrees of set holds the sprinkler as firmly as a new one, and points it somewhere else.\u003c\/p\u003e\n\u003cp\u003eThe symptoms of a bent rod look like problems somewhere else in the spraying system:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoverage heavier on one side of the swath than the other\u003c\/strong\u003e — easily blamed on the flow meter, the pump or a partly blocked line\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA stripe or gap at one edge of the swath\u003c\/strong\u003e — easily blamed on wind, flight height or route spacing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpray landing on the aircraft's own legs or frame\u003c\/strong\u003e — easily blamed on downwash or droplet size settings\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOne sprinkler throwing a lopsided pattern in a water test\u003c\/strong\u003e — easily blamed on the disks or the motor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eA sprinkler that vibrates or shakes more than its partner\u003c\/strong\u003e — easily blamed on a motor bearing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCheck the rod first, because it is the cheapest thing to rule in or out.\u003c\/strong\u003e You do not need a specification sheet; you need the other side of the aircraft.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLook from behind and from the side.\u003c\/strong\u003e With the aircraft on a level surface, stand back and compare the two sprinklers.

The pump, flow meter and valve can deliver exactly the right amount of liquid, and a sprinkler held a few degrees off its line will still put that liquid in the wrong place. The spray rod is the part that decides the line.\u003c\/p\u003e\n\u003cp\u003eWhat makes this part easy to overlook is that it never stops working. A bent rod still carries the sprinkler, still holds it firmly, and still lets the aircraft fly a full day. The cost shows up later, as a stripe in the crop, an edge that was under-applied, or a field that needs a second pass.\u003c\/p\u003e\n\u003cp\u003eThat is also why the check is so useful. Comparing one side of the aircraft with the other costs nothing and needs no tools beyond a tape measure. If the two sides match, the rod is cleared and the search moves on to the disks, motor or flow path. If they do not, the problem has been found before anyone has replaced a motor or recalibrated a flow meter.\u003c\/p\u003e\n\u003cp\u003eBending a rod back by hand is the tempting shortcut. It is also the one most likely to fail again, because a part that has been bent and straightened has been weakened at the bend, and it is very hard to get it back to exactly the line it started on. A new rod restores the original geometry with no guesswork.\u003c\/p\u003e\n\u003cp\u003eWhen the rod is the part that moved, replacing it is the whole repair. When it is not, the checks above will have shown that within a few minutes.\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.
