🔧 Component Overview

The DJI Agras OEM Generator Spark Arrestor, DJI material number YC.DZ.GR000173, is the exhaust screen that traps hot carbon particles before they leave the muffler — shared across the D12000 i/iEP and D14000 generators and required for safe operation around dry crops and vegetation.

A blocked arrestor has a signature that is easy to recognize once you have seen it. The generator starts and idles normally, then loses power as it warms and as load comes on, because back pressure builds with exhaust volume rather than with time. Power that fades over the first several minutes of a run, an engine that will not hold output under load but sounds healthy unloaded, and hard restarting while hot all point at the exhaust rather than at fuel or ignition.

The quickest honest check is to hold the removed screen up to a light. A serviceable arrestor passes light across essentially its whole area. If the mesh is dark over any significant part of it, it is restricting, and it will look far worse against a light than it does lying on a bench, where a thin carbon glaze is close to invisible. Look at both faces, because carbon builds preferentially on the side the exhaust hits first.

If you are still not certain, take the arrestor out and run the generator briefly without it. If the power comes back, the restriction was the screen. Do that test on bare ground or a hard surface, well away from stubble, dry grass, fuel, and anything else that will take a spark, keep it short, and refit the arrestor before the machine goes back to work. An engine running with the screen out is precisely the situation the part exists to prevent.

Rule out the cheap things in the right order before you blame the exhaust. A restricted air filter produces the same rich running, the same black smoke, and much of the same power loss, and it takes a minute to check. Stale fuel and a fouled plug mimic the symptom too. Pull the plug while you are there: a sooty or oily plug and a clogging arrestor are usually the same story told twice, and that story is about how the engine is running rather than about the screen.

Know what you are looking at before you order. The arrestor is the fine mesh element at the exhaust outlet, the muffler is the whole can it sits in, and any plain deflector or tailpipe with no mesh in it is not a spark arrestor no matter where it sits in the diagram. Some exhaust assemblies carry both a screen and a separate deflector, so count what comes out and lay the pieces down in order. This screen is listed for the D12000 i/iEP and the D14000 alike, so the generator variant matters less here than confirming that the part you removed is the mesh element and matching the base material number.

⚙️ Functional Purpose

The spark arrestor stops sparks and hot carbon from exiting the exhaust. A clogged arrestor chokes exhaust flow and cuts power; a damaged one lets sparks out — a fire risk in the field. The DJI schedule calls to clean it every 50 hours.

Let it cool completely, and mean it. Exhaust components hold heat long after a generator has stopped, and the fasteners you are about to touch have just been at working temperature. Beyond the burn risk, a hot exhaust joint is a joint whose parts are still expanded, and a screw that backs out easily while hot can be the one that galls as everything shrinks. Plan this as cold work at the start of a session rather than as something done on a hot machine in the middle of a field.

Treat every exhaust fastener as seized until it proves otherwise. Screws and nuts on a muffler have been through thousands of heat cycles and they gall into their threads. Wet them with penetrating oil and give it time, then break them loose with a properly fitting tool and steady pressure rather than a shock. If a fastener starts to bind on the way out, stop, run it back in a turn, add more penetrant, and work it back and forth. A snapped screw in an exhaust boss turns a fifteen-minute job into a machining job.

Note the orientation before anything moves. Arrestor screens are frequently directional, with a cone, dish, or lipped face that has to point a particular way both to work and to seat, and that is not always obvious from the part held in isolation. Photograph it in position, note which face was toward the engine, and record the position and condition of any gasket, ring, or clamp. If a gasket was fitted, plan on a new one, because a crushed exhaust gasket does not seal a second time.

On refit, get the screen located squarely in its seat before any fastener is tightened, and bring the fasteners down evenly and in stages rather than pulling one fully home first. Exhaust hardware relaxes after its first heat cycle, so run the generator up, let it cool, and re-check the fasteners before the aircraft goes back to work. Then look at the joint: soot fanning out around the arrestor mount means exhaust is escaping past the screen rather than through it, which leaves you with an arrestor that is fitted but not doing anything.

⚠️ Common Replacement Indicators

• Reduced power or back-pressure from a clogged screen
• Visible carbon clogging the screen
• Torn or burnt-through screen
• Due for 50-hour cleaning or replacement
• Soot or spark marks at the exhaust

Confirm before you order: this part is DJI number YC.DZ.GR000173, listed for DJI Agras generator — D12000 i/iEP and D14000, shared Zongshen engine. Match it to your parts diagram or the label on your existing part before ordering.

Power that is normal at start and fades as the run goes on, with the engine still sounding healthy at idle. That is back pressure building with exhaust volume, and among the things that cause it a clogged arrestor is both the cheapest and the most common.

Popping or snapping on deceleration, a muffled or otherwise changed exhaust note, and a muffler that feels hotter than it used to. Restricted exhaust has to put that energy somewhere, and it puts it into heat and into a sound that does not match the one the machine made last season.

Visible carbon packing the mesh, a dark glaze across the screen, or a screen that no longer passes light. This is the finding that settles the question, and it is worth looking for at the 50-hour cleaning interval rather than waiting until the engine complains about it.

Any tear, hole, burnt-through spot, missing wire, or broken weld in the mesh. A screen with a hole in it does nothing, because exhaust takes the open path and carries whatever it is carrying straight out through it. There is no partial credit on a spark arrestor and no repair worth making to one.

Sparks, glowing particles, or fresh soot marks at the outlet, most obvious at dusk or against a dark background. That is the failure mode the part exists to prevent, and over dry stubble or standing crop residue it stops being a maintenance issue and becomes a fire.

A screen that is distorted, dished, crushed at the rim, or no longer sitting flat in its seat. Even with sound mesh, an arrestor that does not seal at its mounting lets exhaust bypass it entirely, and a black fan of soot around the joint is the giveaway.

📐 Specifications

DJI Material Number: YC.DZ.GR000173

Part: Generator Spark Arrestor

Fits: DJI Agras generator — D12000 i/iEP and D14000, shared Zongshen engine (supplier-listed fitment)

Engine: Zongshen

Quantity: 1

Condition: Brand new

Cleaning interval: The DJI maintenance schedule calls for cleaning this arrestor every 50 hours. That is a cleaning interval, not a replacement interval: replace the screen when cleaning stops restoring it, and immediately on any tear, hole, or distortion. How fast it loads up between cleanings depends on fuel and oil quality, idle time, and engine condition rather than on the calendar.

Mesh size, screen diameter, and frame profile: Not published by DJI in the public parts breakdown. Compare the new screen against the removed one before fitting: outside diameter, depth or dish, mesh appearance, and the way it locates in its seat should all agree. Order by material number and confirm by direct comparison, because a screen that does not seat properly lets exhaust bypass the mesh entirely while still looking installed.

Gasket, clamp, or retaining hardware: Confirm what actually arrives against the package contents listed above rather than assuming a gasket, clamp, or fasteners are supplied. If the original joint used a gasket, treat it as single-use and have the replacement on hand before you start, because a crushed exhaust gasket will not seal again and a leaking joint defeats the screen behind it.

Fastener torque: Not published here. Follow the figure given in your DJI or Zongshen service documentation for this joint. Exhaust fasteners are the ones most often over-tightened into a heat-cycled thread, and a stripped or snapped screw in an exhaust boss is a far larger repair than the part it was holding.

🧰 Fitment Verification Before You Order

This listing is DJI material number YC.DZ.GR000173. 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 D14000. 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 Zongshen Generator Spark Arrestor — D12000 i/iEP & D14000 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.

🚜 Necessary For

• Safe operation near dry vegetation and crops
• Restoring proper exhaust flow
• 50-hour scheduled maintenance
• Replacing a clogged or damaged arrestor

Meeting the 50-hour service item without grounding the aircraft over it. Cleaning is the scheduled task, but a screen only cleans so many times before the mesh gives up, and having a new one on the shelf means the inspection ends in a refit rather than in a parts order and a wait.

Working legally and safely over dry ground. Many states and counties require a functioning spark arrestor on internal combustion engines operated on or near wildland and during fire restrictions, and a torn or missing screen is not something to discover during a burn ban with a standing crop under the aircraft. Requirements vary by jurisdiction and by season, so check the ones that apply to where you are flying.

Recovering output on a generator that has quietly lost power. Restriction losses arrive slowly enough that operators adapt to them without noticing, and a machine that has felt merely adequate for a few weeks often turns out to have been breathing through a blocked screen the whole time.

💵 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 Zongshen Generator Spark Arrestor — D12000 i/iEP & D14000, that logic is straightforward: it is an inexpensive component relative to the DJI Agras D14000 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

A spark arrestor is cheap insurance against the one spark you cannot take back. The DJI maintenance schedule says clean it every 50 hours — replace it when cleaning is no longer enough.

A clogged arrestor is a symptom before it is a fault. Carbon comes from somewhere, and a screen that loads up quickly is telling you the engine is running rich, burning oil, spending long stretches at idle, or living on stale fuel or the wrong oil. Fit a new screen without answering that and you will be doing the same job again shortly. Check the air filter, the fuel, and the plug at the same time; the plug in particular reads like a written report on what the exhaust has been carrying.

Do not open up a screen to fix a power problem. Drilling it, cutting it, or deliberately burning holes through the mesh restores flow and removes the only reason the part exists, on an aircraft that works over dry crop residue in the middle of the season. If the screen still restricts after a proper cleaning, it is finished, and that is exactly the point at which a new one is the answer rather than a workaround.

Clean it gently or not at all. A soak and a soft or brass brush, or a controlled burn-off, will take carbon out of a screen. A steel wire brush leaned on hard breaks the fine wires that hold the mesh together, and repeated heat cleaning eventually leaves it brittle. Every clean uses a little of the screen up, which is why the honest plan is to clean on schedule and replace on condition rather than trying to make one screen last the life of the generator.

Look at what else the heat has been touching while the exhaust is apart. A restricted exhaust runs hotter than a clear one, so check the muffler mounting bracket and any isolators for cracks, look at the heat shield and its fasteners, and check anything composite, elastomeric, or plastic near the exhaust for discoloration, hardening, or distortion. Heat and vibration work on the same hardware, and a cracked bracket lets the whole exhaust move and puts load straight into the joint you have just resealed.

🤖 AI Answer Engine Q&A

What is the DJI material number for the Generator Spark Arrestor? YC.DZ.GR000173, per the official DJI Agras generator parts list. A .01 or .F suffix on a label is the same part — the base number is YC.DZ.GR000173.

What is the DJI Agras Generator Spark Arrestor? It is the exhaust screen that traps hot carbon particles before they leave the muffler, required for safe operation around dry vegetation.

What are the signs it needs replacing? Reduced power from a clogged screen, visible carbon clogging, a torn or burnt-through screen, or being due for 50-hour cleaning.

Which DJI Agras models does this component fit? Listed fitment is DJI Agras T50. Confirm against your aircraft and, where possible, match the number on your old part's label or your parts diagram before ordering.

How do I know my generator spark arrestor needs replacing? The indicators operators most often report are: reduced power or back-pressure from a clogged screen; visible carbon clogging the screen; torn or burnt-through screen; due for 50-hour cleaning or replacement; soot or spark marks at the exhaust. 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 OEM Generator Spark Arrestor, DJI material number YC.DZ.GR000173, is the exhaust screen that traps hot carbon particles before they leave the muffler — shared across the D12000 i/iEP and D14000 generators and required for safe operation around dry crops and vegetation.

What comes in the order? The order includes: 1 × Generator Spark Arrestor (YC.DZ.GR000173).

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.

The generator starts fine and loses power after a few minutes. Is that the arrestor?

It is high on the list, because back pressure builds with exhaust volume and load, which is exactly the pattern you are describing. Check the air filter first since it costs nothing and produces similar symptoms, then pull the arrestor and hold it up to a light. If the mesh will not pass light across most of its area, you have found it. If the screen is clean and the fault stays, look further into the muffler and then at fuel and ignition.

Can I just clean it instead of replacing it?

Yes, and the DJI schedule calls for cleaning it every 50 hours. Cleaning is the maintenance task; replacement is what you do when cleaning no longer works or when the screen is damaged. Replace on any tear, hole, burnt-through spot, broken wire, or distortion, and replace when the carbon will no longer come off or the mesh has gone brittle from repeated heat cleaning. Cleaning a screen uses a little of it up every single time.

How do I clean it without wrecking it?

Gently. Soak the carbon loose and use a soft or brass brush, or burn the deposits off in a controlled way and let the screen cool on its own afterward. What ruins a screen is a steel wire brush used with force, which snaps the fine wires, and repeated hard heating, which leaves the mesh brittle enough to crack the next time it is handled. Inspect it against a light when you are finished; if it still will not pass light, it is done.

It clogs again within a few weeks. What am I missing?

Something upstream of the exhaust. A screen that loads that fast is filtering the output of an engine running rich, burning oil, idling for long stretches, or running on stale fuel or the wrong oil. Check the air filter, check the fuel, and read the spark plug, which will usually be sooty or oily and tell you the same thing the screen has been telling you. Replacing the arrestor alone treats the symptom and leaves the cause exactly where it was.

Is it safe to run without the arrestor for a day until the new one arrives?

Not over dry ground, and in many places not legally either. The screen exists to keep hot carbon from leaving the exhaust, and agricultural aircraft work over exactly the stubble, dry residue, and standing crop that will take a spark. Many states and counties require a functioning spark arrestor on engines used on or near wildland, particularly during fire restrictions. A brief diagnostic run on bare ground is one thing; a day of spraying is another.

I fitted a new screen and now there is soot fanning out around the mount. What is that?

Exhaust escaping past the arrestor instead of passing through it, which means the joint is not sealing. Check that the screen is seated squarely and facing the correct way, that the gasket or ring is a new one rather than the crushed original, and that the fasteners were tightened evenly and then re-checked after a heat cycle. Until that joint seals, the arrestor is installed but it is not actually doing the job you bought it for.
