🔧 Component Overview

The DJI Agras T50 OEM Spreading System Short Shaft, DJI material number YC.JG.QX003086, is the machined short drive shaft in the spreading system, transferring rotation between the drive components and the spreading disc with the concentricity a clean spread depends on.

The spreading system asks more of a small machined part than almost anything else on the aircraft. Granular fertilizer is abrasive going in and corrosive sitting still, and the short shaft runs inside that stream, at speed, with dust in the air around it. Everything that makes a spread pattern repeatable, the disc turning flat and true at a known speed, depends on this shaft staying straight and staying tight in whatever holds it.

Wear on a drive shaft in a granular machine is rarely a single event. Fine granule dust works past a seal or a shield, mixes with moisture and whatever oil is present, and becomes a lapping compound that polishes a bearing journal down over a season. By the time an operator can feel play at the disc, the shaft has usually lost material at one specific band rather than along its whole length, which is why a worn shaft looks fine until you run a fingernail across it.

Corrosion is the other half of the story and it is specific to what you are spreading. Urea pulls moisture out of the air and holds it against metal. Potash and ammonium sulfate blends are aggressive on bare steel. A shaft that spends a night with damp product packed around the hub is being attacked in exactly the places that matter, under a hub or under a bearing race where nothing can dry out and nobody looks.

⚙️ Functional Purpose

The short shaft transmits drive rotation truly and concentrically. A worn, scored, or bent shaft introduces runout and play that show up as vibration and an uneven spread pattern.

The shaft is what makes disc speed mean something. A spread pattern is calibrated on the assumption that the disc turns at a commanded rate in a flat plane, so material leaves the vanes at a predictable velocity and a predictable angle. A shaft with runout tilts that plane once per revolution. Material then leaves high on one side and low on the other, and the pattern that was calibrated on a test surface stops matching what lands in the field.

It also isolates the drive from the punishment happening at the disc. The disc takes impacts from clods, foreign objects, and the occasional stone that comes down the hopper, and the shaft is the path those shocks travel to reach the bearings and the motor behind it. A straight, correctly seated shaft passes torque and rejects the rest. A loose or worn one lets the disc move under those impacts, and the movement is transmitted straight into the parts it should be protecting.

There is a metering dimension too. On a spinner spreader the rate is set by the opening feeding the disc and the disc speed together. If the shaft allows the disc to shift axially, the gap between the disc face and whatever it runs beneath changes as it runs. That turns a fixed metering geometry into a variable one, and it is a common reason a machine calibrates correctly on the ground and applies inconsistently in the air.

⚠️ Common Replacement Indicators

• Runout, wobble, or vibration in the spreading drive
• Play where the shaft meets its bearings or coupling
• Scoring, wear, or bending on the shaft
• Noise from the spreader drivetrain
• Uneven spread pattern traced to the shaft

Confirm before you order: this part is DJI number YC.JG.QX003086, listed for DJI Agras T50 spreading system. Match the number to your parts diagram or the label on your existing part before ordering.

A once per revolution shake that gets worse as disc speed rises. That signature is imbalance or runout, and on this assembly it is either a bent shaft, a damaged disc, or a hub that is not seated square. Bearing damage sounds different: it is a continuous growl or rumble that does not track disc speed in the same clean, once around rhythm.

Play you can feel at the rim of the disc when you rock it by hand with the machine powered down. The rim is a long lever, so a very small clearance at a bearing journal or a slack drive feature shows up as obvious movement out there. Feel for it in two directions separately, rocking the disc across its face and then pulling and pushing along the axis of the shaft.

A polished or stepped band on the shaft where a bearing or hub sits. Run a fingernail along the shaft after cleaning it. If the nail catches at the edge of a shiny band, material has been worn away there, and the fit that band was machined for no longer exists. That is not restorable and it is the most common way this shaft is condemned on the bench.

Discoloration, blueing, or heat marking at a seat. That says the shaft has been running hot, usually because it has been turning inside something that was supposed to be locked to it. Once a seat has spun, it will keep spinning, and the heat will find the parts around it. Anything with a heat signature at a bearing or hub seat gets replaced rather than reinstalled.

Pitting or a rough, dull grey texture under where a hub or race sat. That is fertilizer corrosion working in a place that never dries. Pitting at a load bearing surface is a stress raiser as well as a fit problem, and a shaft that is pitted in a journal will not hold a bearing correctly no matter how clean you get it.

A spread pattern that has drifted off center or grown a heavy streak, with no change to hopper settings, product, or flight parameters. When the settings did not change and the pattern did, something mechanical changed. Runout at the disc is one of the few faults that alters the pattern without altering anything the operator can see on the controller.

📐 Specifications

DJI Material Number: YC.JG.QX003086

Part: Spreading System Short Shaft

Fits: DJI Agras T50 spreading system (supplier-listed fitment)

Quantity: 1

Condition: Brand new

Position in the system: Short drive shaft in the T50 spreading system, carrying rotation from the drive components through to the spreading disc

Published dimensions: DJI does not publish shaft length, journal diameters, or runout tolerance in the public parts list. Do not size from a forum post. Compare the new shaft directly against the removed one before fitting.

Fastener and retainer torque: Not published in the public parts documentation. Use the values in your DJI service manual for the spreading system hardware, applied with a calibrated driver.

Sold as: Shaft only. Bearings, retainers, seals, the coupling or drive hardware, and the spreading disc are separate line items on the parts diagram and are ordered under their own numbers.

🧰 Fitment Verification Before You Order

This listing is DJI material number YC.JG.QX003086. That number, not the description, is what makes a part match. Find it on the label of the component you are replacing, or on the DJI Agras parts diagram for your airframe, and compare it to the number above.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T50. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Spreading System Short Shaft is easier to fit correctly when you can see how the original sat.

Torque to DJI specification. Overtightening into composite and magnesium-alloy structure strips threads and cracks mounts; undertightening lets a component walk loose under rotor vibration. Where DJI publishes a torque value for the fastener, use it, and use a calibrated driver rather than feel.

Check the mating surfaces and seals while you are in there. A component is only as good as what it seats against. Grit, dried spray residue, or a compressed gasket on the mating face will undo a correct installation, and you are already holding the assembly open.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

💵 What Downtime Actually Costs

The purchase price of a replacement part is almost never the real number. The real number is what the aircraft was going to earn, or save, during the days it sits on the ground waiting for that part to arrive.

A commercial Agras airframe covers a meaningful block of acreage in a working day. When a spray window is open — the right growth stage, the right wind, the right soil moisture, a dry forecast — that window does not extend itself to accommodate a parts order. It closes. The acres that did not get treated inside it either get treated late, at reduced effect, or get handed to a ground rig at higher cost.

Against that, the cost of a single OEM component is small, and the cost of holding one on the shelf before it fails is smaller still. Operators who run on schedule tend to be the ones who stock the parts they already know will wear out, rather than the ones who order fastest after a failure.

For the Spreading System Short Shaft, that logic is straightforward: it is an inexpensive component relative to the DJI Agras T50 it serves, it is a known service item rather than a surprise, and having one in the truck or the shop converts a multi-day grounding into an afternoon of work.

This is also why we ship from U.S. stock rather than drop-shipping from overseas. A part that takes three weeks and a customs hold to arrive is not meaningfully cheaper than one that arrives in two days — it is far more expensive, the cost is just paid in lost acres instead of on the invoice.

💡 Why This Part Matters

Everything downstream of the drive shaft assumes it spins true. A worn shaft puts runout into the whole spreading system and the pattern shows it. A small machined part that protects the accuracy of every granular acre.

Fitting new bearings to a worn shaft is the most expensive mistake available on this assembly. The bearing is sized for a specific interference on the journal. If that journal has been worn or corroded undersize, the new bearing turns on the shaft instead of the shaft turning in the bearing, and the second set of bearings fails faster than the first. Operators who chase a spreader vibration through two bearing kits are usually chasing a shaft.

The cost of running on a marginal shaft is not measured in parts, it is measured in product. A spreader that is throwing a skewed pattern is applying the wrong rate across part of every pass, and nobody sees it until the crop shows stripes weeks later. At that point the fertilizer is spent, the season is committed, and no repair recovers the acres that were underfed or the money spent on the ones that were overfed.

This is also a part that goes without warning once it starts moving in a seat. A worn but tight shaft can run for a long time. A shaft that has begun to spin inside a hub generates heat, the fit opens up further, and the failure arrives quickly, at speed, with a loaded disc attached to it. That is a good reason to condemn a marginal shaft on the bench rather than send it back out for one more field.

How do I know my spreading system short shaft needs replacing? The indicators operators most often report are: runout, wobble, or vibration in the spreading drive; play where the shaft meets its bearings or coupling; scoring, wear, or bending on the shaft; noise from the spreader drivetrain; uneven spread pattern traced to the shaft. Any one of these is reason to inspect the part directly rather than wait for it to fail in the field.

What does this component actually do on the aircraft? The DJI Agras T50 OEM Spreading System Short Shaft, DJI material number YC.JG.QX003086, is the machined short drive shaft in the spreading system, transferring rotation between the drive components and the spreading disc with the concentricity a clean spread depends on.

What comes in the order? The order includes: 1 × Spreading System Short Shaft (YC.JG.QX003086).

Is this a genuine DJI OEM part? Yes. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller and stocks genuine DJI Agras OEM replacement parts. This component is supplied brand new.

How do I tell whether the wobble is the shaft or the spreading disc?

Index the disc and see whether the fault follows it. With the machine powered down, mark the high point of the wobble on the disc and mark its position relative to the airframe. Remove the disc, rotate it half a turn on the shaft, and refit it. If the high point moved with the disc, the disc is at fault. If the high point stayed in the same place relative to the aircraft, the fault is in the shaft or its seat.

How do I separate a worn short shaft from a failing spreader motor?

Take the load off and listen to each piece on its own. With the disc removed, turn the drive slowly by hand and feel for roughness, notchiness, or a catch that repeats at a fixed point. Roughness that is still there with the shaft and disc off belongs to the motor. A drive that turns smoothly on its own but wobbles as soon as the disc is fitted points at the shaft, its seat, or the drive feature between them.

The spread pattern went heavy on one side and nothing on the controller changed. Is the shaft a likely cause?

It is one of the short list of mechanical faults that does exactly that. Runout tilts the plane of the disc, so material leaves the vanes at a different angle on one side of every revolution than on the other, and the result is a pattern that has shifted or grown a streak while every setting stayed the same. Check disc condition and vane wear first, then check shaft runout and the seats it rides in.

What is the removal and refit sequence for the short shaft?

Empty the hopper, power down, and disconnect the flight batteries. Photograph the stack before you take it apart, because the order of retainers, shims, and spacers matters and none of it is obvious once it is in a tray. Support the assembly instead of prying against the disc or the motor housing. Clean every seat before the new shaft goes in, start all hardware by hand, and turn the assembly through several full revolutions by hand before the drive is powered.

Can a bent short shaft be straightened and reused?

No. Straightening a hardened, machined shaft leaves residual stress and does not restore concentricity between the journals and the drive feature, which is the entire reason the part exists. Even a shaft that runs acceptably after straightening carries a bend that will work its way back under load and heat. Anything that fails a roll check or a runout check gets replaced.

Why did my shaft wear out in a single season?

Almost always because product got somewhere it should not be. Granule dust that reaches a bearing journal turns into a grinding paste, and once material starts coming off the shaft the fit opens up and the ingress gets worse. Look hard at whatever seal, shield, or cover is meant to keep product out of the drive, because fitting a new shaft behind a failed one buys a season at most.

What else should I inspect while the shaft is out?

Inspect the bearings for roughness or a gritty feel, and the bearing housings for a bore that has been worn oval or is discolored. Check the drive feature and its mating part for rounding, and the retaining hardware for stretch. Look at the disc hub bore, the vanes for uneven erosion, and any seal or shield for tearing or packed product. Clean the hopper outlet and the metering area while you have access to them.

How should a spare shaft be stored, and does it need anything before it goes in?

Keep it in its packaging, lightly oiled, in a dry place well away from open fertilizer. Airborne granular dust in a farm shop will find bare machined steel and start pitting it on the shelf. Before installation, wipe it clean and dry, look over the journals and the drive feature under good light, and roll it on a known flat surface to confirm nothing happened to it in transit.

Is this the same part as the other shaft in the spreading system?

No. The spreading system parts diagram lists more than one shaft, and they are separate DJI material numbers. This listing is YC.JG.QX003086 only. If you have both parts in front of you, compare overall length, the number and position of any steps or shoulders, retaining groove locations, and the drive feature at the end. Order by the base number on the diagram rather than by appearance.
