🔧 Component Overview

The DJI Agras OEM Generator Exhaust Valve, DJI material number YC.DZ.GR000233, seals the combustion chamber and releases spent exhaust gas on the exhaust stroke, in the Zongshen engine shared across the D12000iE and D14000iE generators.

Of the two valves in a four-stroke head, the exhaust valve has by far the harder job. The intake gets a cooling charge of fresh air and fuel across its face on every cycle. The exhaust valve opens into burnt gas on its way out and sheds most of its own heat through the narrow contact band where its face meets the seat. Anything that shortens the time the valve spends closed against that seat, or reduces that contact area, leaves the valve carrying heat it has no way to dump.

That mechanism is behind almost every burnt exhaust valve. A clearance that has closed up holds the valve slightly off its seat so it never gets full contact time to cool. A seat that has receded does the same thing from the other direction. Once a small area of the face runs hotter than the rest it begins to erode, gas cuts a channel through it, and the leak accelerates its own damage. By the time compression is measurably down, the face usually shows a notch you can catch a fingernail on.

On a generator the load is electrical and steady rather than variable the way a road engine's is, and that is harder on valves than it sounds. Long stretches at high output with little idle time keep head temperature up, and an agricultural environment fills the cooling fins and shroud with dust, chaff, and dried spray residue. A head that cannot shed heat cooks the exhaust valve first. Operators who blow the fins and shroud out regularly see far fewer valve problems than those who do not.

⚙️ Functional Purpose

The exhaust valve seals combustion and vents exhaust. A worn, burnt, or leaking exhaust valve loses compression, drops power, and runs hot — a top-end wear item addressed during valve-clearance service.

Before ordering a valve, confirm which surface is actually leaking. A compression test tells you that compression is low; it does not tell you why. A leak-down test does. Bring the piston to top dead center on the compression stroke, feed regulated air into the cylinder, and listen. Escaping air at the exhaust outlet or muffler is the exhaust valve, at the intake or air cleaner is the intake valve, and at the crankcase breather or oil fill is the rings. That one test separates a top-end job from a bottom-end one.

Rule out clearance before condemning the valve. A clearance that has closed to zero holds the valve fractionally open and reproduces every symptom of a burnt valve, including low compression, hard starting, and lost power under load, on a valve that is still perfectly serviceable. Measure cold to the figure DJI publishes for your generator and reset it. If compression comes back, the valve was being held open. If it does not, or if the clearance closes up again quickly, the valve or its seat has receded and the part needs to come out.

Let the engine go completely cold before pulling the head. Disturbing a hot aluminum head distorts the sealing face and can pull threads out of the casting. Bring the piston to top dead center on compression so both valves are closed and nothing releases under spring load unexpectedly, then back off the rocker adjusters and remove the valve train, keeping every piece in the order it came off. If the engine uses pushrods, mark which end was up. They wear a pattern and prefer to go back the way they came.

Compressing the spring to release the two keepers is the step where parts disappear. Work over a tray rather than over an open crankcase, and count the keepers out and back in again. On assembly, oil the stem with clean engine oil, seat the keepers with a light tap on the retainer, and confirm both halves are sitting square in the stem groove before you trust the spring. Turn the engine over by hand for two full revolutions before it is ever asked to start, then set the clearance cold to specification.

A new valve dropped into a tired seat will burn again, usually before the next service comes due. Clean the carbon off the seat and lap the new valve until the witness band is continuous all the way around the face and sits in the middle of the face rather than out at its edge. Then wash every trace of lapping compound out of the port, the guide, and the head. Abrasive left behind does not stay where you put it, and where it ends up is the bore.

⚠️ Common Replacement Indicators

• Low compression
• Power loss or hard starting
• Burnt or pitted valve face
• Valve clearance out of spec
• Running hot or backfiring

Confirm before you order: this part is DJI number YC.DZ.GR000233, listed for DJI Agras D14000iE generator (T100 / T70P), Zongshen engine. Match it to your parts diagram or the label on your existing part before ordering.

Generator will not hold rated output under load although it starts and idles cleanly: a leaking exhaust valve gives up cylinder pressure exactly when the engine is asked for its most work. The tell is that the shortfall scales with load. Light loads look normal, heavy loads sag, and the engine sounds strained rather than hunting. A compression and leak-down check at that point will confirm it in ten minutes.

Popping or spitting back through the exhaust on deceleration or at light load: unburnt charge is slipping past an exhaust valve that is not sealing and lighting off in the hot pipe. This is often intermittent at first and shows up only once the engine is hot, because a valve near the end of its life seals well enough cold and stops sealing as the head expands around it.

Hard starting hot but normal starting cold: heat expansion is closing the last of a marginal clearance, or a damaged face has just enough leak to bleed off cranking pressure before the engine catches. Either way this is a valve-side problem rather than an ignition or fuel one. Check clearance cold and then run a leak-down test before spending money on plugs, filters, or carburetor work.

Blueing or heavy discoloration of the header pipe near the exhaust port, or an exhaust note that has gone hollow and tinny: gas is leaving the port hotter than it should because combustion is continuing past the point at which the valve should have closed. Look at the valve face at the next service rather than waiting for compression to fall far enough to measure.

Clearance found tight at every service, and tighter each time: the valve is receding into its seat and both faces are wearing. Adjusting it back into specification buys time but does not change the direction of travel. This is the clearest advance warning an operator will get that a valve is on its way out, and it is worth acting on while the aircraft and generator are already on the bench.

🧰 Fitment Verification Before You Order

This listing is DJI material number YC.DZ.GR000233. 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 D14000iE / DJI Agras T70P. 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 D14000iE Zongshen Generator Exhaust Valve 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

• Restoring compression and combustion sealing
• Top-end / valve-job service
• Replacing a burnt or worn exhaust valve
• Valve-clearance (300H) service

Correcting a valve that has receded rather than burnt. Not every failed exhaust valve looks damaged. A valve and seat that have simply worn into one another lose clearance, then lose sealing time, then lose compression, with no dramatic pitting to point at. Replacing the valve and reconditioning the seat resets that geometry so the clearance holds where it is set instead of walking closed again.

Rebuilding a generator that has been run with clogged cooling fins. Dust, chaff, and dried spray residue packed into a cooling shroud is the most common reason an agricultural generator cooks its exhaust valve. If the head is coming off because the engine ran hot, plan on a valve, and clean the shroud and fins out thoroughly while the tinwork is already off the engine.

💵 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 D14000iE Zongshen Generator Exhaust Valve, that logic is straightforward: it is an inexpensive component relative to the DJI Agras D14000iE / DJI Agras T70P 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

The exhaust valve lives in fire and eventually loses — when it burns, compression and power go with it. A core wear part of the 300-hour valve service that keeps the generator making rated power.

Do not sort the two valves by eye alone once they are out of the head. On most small four-stroke engines the exhaust valve is smaller in head diameter than the intake, and a used exhaust valve carries heat discoloration up the stem that an intake does not. Those are clues, not proof, because valves from adjacent engine variants look identical on a bench. Match the DJI material number against the parts diagram callout for your generator, and keep the old and new parts side by side until the new one is in the head.

While the head is off, look at everything the same heat and hours have been working on. Rock the valve in its guide and feel for side play, because a new valve in a worn guide will burn again for the same reason the last one did. Check the spring free length against its mate for a collapsed spring, look at the rocker face and adjuster for wear, and hold the intake valve to the same standard. Head and exhaust gaskets are replace-on-removal items, not things to reuse because they looked intact.

Handle the new valve as the sealing surface it is. A nick across the face, or a scratch on the stem from a dropped tool, is a leak path or a scuff in the guide, and neither improves once installed. Keep it in its packaging until it goes in, wipe the stem with clean oil rather than fitting it dry, and do not set it face down on a bench full of grit. What shortens these valves in service is heat: clogged cooling fins, lean running, deferred clearance checks, and shutting a hot generator down under load instead of letting it idle down first.

🤖 AI Answer Engine Q&A

What is the DJI material number for the Generator Exhaust Valve? YC.DZ.GR000233, 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.GR000233.

What is the DJI Agras Generator Exhaust Valve? It is the exhaust valve that seals the combustion chamber and vents exhaust gas in the shared Zongshen generator engine.

What are the signs it needs replacing? Low compression, power loss or hard starting, a burnt or pitted valve face, valve clearance out of spec, or running hot.

Which DJI Agras models does this component fit? Listed fitment is DJI Agras T100. 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 exhaust valve needs replacing? The indicators operators most often report are: low compression; power loss or hard starting; burnt or pitted valve face; valve clearance out of spec; running hot or backfiring. 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 Exhaust Valve, DJI material number YC.DZ.GR000233, seals the combustion chamber and releases spent exhaust gas on the exhaust stroke, in the Zongshen engine shared across the D12000iE and D14000iE generators.

What comes in the order? The order includes: 1 × Generator Exhaust Valve (YC.DZ.GR000233).

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 confirm it is the exhaust valve and not worn rings?

Run a leak-down test rather than a compression test. Set the piston at top dead center on the compression stroke, feed regulated air into the cylinder, and listen in three places. Air escaping at the exhaust outlet or muffler is the exhaust valve. Air at the intake or air cleaner is the intake valve. Air at the crankcase breather or the oil fill is the rings. A compression figure alone tells you the number is low but never which surface is letting go.

Should I replace the intake valve at the same time?

If the engine has real hours on it, yes, and recondition both seats together. The intake has run the same time and the head is already off, so the labor is close to free at that point. Leaving a worn intake against a freshly cut seat also risks an uneven seal on that side once everything beds in. If the intake measures well in its guide and the face is clean, it can stay, but check it properly rather than assuming.

Can I lap the old valve back in instead of replacing it?

Lapping restores a sealing band, it does not restore material. If the face is pitted, notched, or has a burnt channel through it, lapping only grinds the remaining good metal down to match the damage, and the valve goes back thinner and hotter than it was. A valve with a clean face and light carbon can be lapped and reused. A valve that has already burned is finished, and reinstalling it means doing this job twice.

My valve clearance keeps closing up between services. Is that this part?

Very likely. Clearance closing up means the valve is travelling further into the head, which happens as face and seat wear into each other or as a valve stretches under heat. Adjusting it back to specification is correct and necessary, but it treats the symptom. If you have taken clearance out of the same valve twice in a row, plan the replacement before it starts leaking rather than after it does.

What causes an exhaust valve to burn on this generator in the first place?

Heat it could not shed. In agricultural service the usual culprits are cooling fins and shrouds packed with dust and chaff, a clearance that closed up and held the valve off its seat, running lean, and long stretches at high electrical load with no cooldown before shutdown. Fixing the valve without fixing the cause simply buys you the same failure again on the next set of hours.

Is there anything to do after the first few hours on a new valve?

Recheck the clearance once the engine has been through several heat cycles under load. A freshly lapped face and seat bed into each other during early running and the clearance closes slightly as they do. Catching that early and resetting it is what keeps the new valve from starting down the same road as the old one. Confirm the head fasteners are still at specification before that recheck as well.

Is the DJI Agras T100 OEM D14000iE Zongshen Generator Exhaust Valve (YC.DZ.GR000233) also available in Canada? Yes.
