🔧 Component Overview

The DJI Agras T100 OEM D14000iE Zongshen Generator Cylinder Head, DJI material number YC.DZ.GR000704, is the aluminum casting that closes the top of the cylinder on the engine inside the DJI Agras D14000iE multifunctional inverter generator — the field charging station that keeps a T100, T70P or T55 battery rotation supplied away from shop power. It sits directly on the crankcase barrel with the head gasket between them, and it brings four things to the engine in one part: the shaped combustion chamber, the valve seats and guides that let the valves seal and stay aligned, the intake and exhaust ports that carry the charge in and the spent gas out, and the cooling fins that shed the heat of combustion.

For a fleet operator running field charging, the head is where power actually gets made or lost. Everything the engine does under sustained charging load depends on the combustion chamber sealing and the valves closing on clean, square seats. When those seats recess or burn, the engine does not stop — it just quietly gives back output, and the operator sees it as packs taking longer to come back than they used to. That is a hard fault to chase from the outside and an easy one to confirm with a compression check, which is why the head belongs on the diagnostic list any time a charging generator loses its edge without an obvious cause.

Start the diagnosis with a compression test and run it twice, because a single reading cannot tell you whether the leak is at the valves or past the rings. Take the first reading dry, throttle held open, plug out, cranking until the gauge stops climbing. Then put a small squirt of engine oil down the plug hole and repeat. If the second reading jumps well above the first, the seal that was leaking is at the rings and the head is not your problem. If it barely moves, the leak is above the piston, which means valves, seats or head gasket.

A leak-down test tells you exactly which part is leaking and it takes minutes. Bring the piston to top dead center on the compression stroke with both valves closed, hold the crankshaft against rotation, feed regulated air into the plug hole, and then listen. Air out of the carburetor throat or air cleaner is an intake valve or its seat. Air out of the muffler is an exhaust valve or its seat. Air out of the oil fill or the crankcase breather is rings and bore. Air escaping along the outside of the head-to-barrel joint is the gasket.

Read the spark plug and the outside of the joint before you commit to pulling anything apart. A plug that comes out wet and oily on a generator that also smokes at start-up after standing points at valve guides and stem seals rather than at the chamber. A dry, sooty plug on an engine that is down on power points at breathing and sealing. On the outside, look along the parting line between head and barrel for a fine track of soot or a clean streak washed through the dust, which is combustion gas escaping past the gasket and showing you where.

Once the head is off, the casting answers the rest of the questions on the bench. Lay a true straightedge across the gasket face in several directions and try a feeler gauge under it to find warp or a dish worn into the aluminum. Look at each seat for a contact ring that is uneven, wide, pitted, or sunk below the surrounding metal. Rock each valve sideways in its guide with the valve off the seat and feel for slop, which is a worn guide. Check the plug boss and the stud threads, because pulled threads condemn a casting as surely as a crack does.

⚙️ Functional Purpose

The cylinder head's job is to contain combustion and to control breathing. On the containment side, the chamber and the gasket face have to hold peak cylinder pressure without leaking, cycle after cycle, and the valve seats have to give each valve a gas-tight landing face at full combustion temperature. On the breathing side, the ports and guides set how freely the engine draws in and pushes out, and the guides hold the valve stems in alignment so the valve face and the seat meet the same way every single cycle. The fins do the work that makes all of it survivable: an air-cooled head with clear fins runs at the temperature it was designed for, and an air-cooled head with fins packed full of chaff does not.

What degrades when the head fails is compression, and compression is output. A recessed or burned seat lets combustion pressure past the valve, so the cylinder makes less power and the exhaust or intake side runs hotter than it should. A worn guide lets the valve wander and hammer its seat off-centre, which accelerates the seat damage and pulls oil down the stem into the chamber. A warped or eroded gasket face blows head gaskets repeatedly no matter how many new gaskets go in. A crack in the casting ends the argument outright. In every case the result on a charging generator is the same: less power under sustained load, slower battery turnaround, and aircraft waiting.

Getting the head off is a sequence, and the order matters more than the speed. With the engine cold and the fuel and oil drained, take the recoil housing and the cooling shroud off first so the fins and the head fasteners are visible and reachable. Pull the plug lead and the plug. Free the exhaust and intake sides, muffler, manifold, carburetor and their gaskets, so that nothing is left bolted to both the head and the crankcase at the same time. One forgotten bracket will fight you and bend something the moment you lift.

Then the valve gear. Take the valve cover off, back the rocker adjusters off, remove the rocker gear, and lift the pushrods out. Keep them in order and the same way up, because a used pushrod that goes back rotated or swapped end for end no longer runs on its bedded-in wear pattern. Loosen the head fasteners in stages and in the reverse of the tightening pattern, outside working in, so the casting relaxes evenly instead of being sprung by the last one. Lift the head straight up. If it is stuck, tap sideways at a cast boss with a soft mallet; never drive a screwdriver or a chisel into the joint, because one gouge in an aluminum sealing face turns a repair into a second repair.

With the head off, put a clean rag into the bore and around the studs before you clean anything, so nothing you scrape off can fall where it will do damage. Take the old gasket off both faces with a plastic or brass scraper and solvent. Do not use a wire wheel, an abrasive disc, or a steel blade on the aluminum face: they leave scratches that run straight across the seal and they load the joint with grit. Blow the fastener holes out and make sure they are clean and dry to the bottom, because oil or debris trapped in a blind hole absorbs torque that never reaches the joint and can split the casting.

On the way back together, fit the new gasket over the dowels dry unless the service documentation says otherwise, and never reuse the old one. Drop the head straight down rather than sliding it into place. Seat the pushrods properly in both the lifter cups and the rocker sockets, because a pushrod sitting beside its socket instead of in it will bend on the first revolution. Bring the fasteners up in the documented pattern in several rising stages rather than in one pull. Set the valve clearances with the piston at top dead center on the compression stroke and both valves fully closed, then turn the engine over by hand before it ever sees the starter.

⚠️ Common Replacement Indicators

• Low or falling compression that does not recover after a valve clearance adjustment
• Cracks in the head casting, through a fin, or between the valve seats
• Recessed, pitted, burned or leaking valve seats found at inspection
• Worn valve guides showing stem rock, oil consumption, or smoke on start-up
• A warped, gouged or eroded gasket face that keeps blowing head gaskets
• Damaged or pulled spark plug threads, stud threads, or broken cooling fins

Confirm before you order: this part is DJI material number YC.DZ.GR000704, supplier-listed for the DJI Agras D14000iE multifunctional inverter generator in the Zongshen engine build. DJI dual-sourced these generator engines, so read the engine label on your own unit before ordering and match the base material number rather than matching on appearance — heads across engine families look alike, and a revision suffix such as .01 or .F still indicates the same base part. Before committing, rule out the cheap causes of low compression first: check valve clearances, check that the head bolts are at correct torque, and confirm the loss is not simply a head gasket. Then pull the head and inspect the seats, the guides and the gasket face with the casting clean.

Why it fails: heat, hours and cycles. The head is the hottest part of the engine and it swings from ambient to full combustion temperature every working day of the season, which works the casting, the seats and the gasket face continuously. Cooling fins packed with field dust, chaff and chemical residue raise head temperature and accelerate all of it. Valve seats recess and burn over thousands of hours of sustained charging load, particularly when valve clearances go unadjusted and the valves stop closing fully. Guides wear oval. And a single event — running low on oil, a lean mixture, a dropped valve, or unfiltered air reaching the chamber — can take a head out in an afternoon.

Post-install checklist: inspect the new casting before you begin — check the gasket face for shipping damage, check the seats and guides, confirm the ports are clear and the fins are undamaged. Clean both mating faces completely, fit a new head gasket, and torque the head down using the sequence, values and stages given in the DJI and Zongshen service documentation rather than any figure quoted from memory. Set valve clearances to the documented specification. Then inspect again before first start: confirm the rocker gear and pushrods are correctly seated, confirm the plug is torqued, confirm oil and fuel are to specification, and confirm nothing is fouling the fins. Run the generator up, bring it to full operating temperature, shut down and let it cool, then re-check head torque and valve clearances and inspect for any leak at the gasket line before it goes back on the charging line.

The generator starts and idles normally but bogs and gives back output the moment a full rack of chargers is switched on: the engine cannot hold power under load. A leaking seat costs a roughly fixed amount of cylinder pressure per cycle, which barely shows at light load and becomes obvious when the engine is asked for everything it has.

Hard hot starting on a unit that starts easily from cold: hot metal grows, and a valve already sitting proud of a recessed seat gets held off that seat as the head and stem expand. The engine loses the compression it needs to fire until it cools down again. This is one of the most reliable early signals of seat recession.

Popping or spitting back through the carburetor or the air cleaner under load: an intake valve is not sealing and burning charge is escaping back up the intake port. Confirm it with a leak-down test at top dead center and listen at the carburetor throat before you start condemning fuel delivery or ignition components.

A sharp, hollow puff out of the exhaust at idle, in time with the engine rather than random: an exhaust valve or its seat is leaking. Exhaust-side leaks accelerate, because the escaping combustion gas heats the leak path and erodes the seat a little further every hour the engine runs.

Blue smoke at start-up that clears after a minute and does not come back until the generator has stood overnight: oil has drained down worn valve guides and past the stem seals into the chamber. Continuous blue smoke under load is more likely rings, so use the wet compression test to tell the two apart before ordering anything.

Head gaskets that fail repeatedly, sometimes within hours of a careful rebuild: the gasket is not the fault. Either the gasket face is warped or eroded, the fastener holes or threads are compromised so torque is not holding, or the fasteners themselves have stretched. Check the face with a straightedge before you fit another gasket.

One area of the cooling fins is discolored, or a fin is cracked or missing while the rest look normal: the local heat path is broken and the metal under it is running hotter than it was designed to run. Fin damage is often the visible half of an impact that also cracked the casting somewhere less obvious.

The engine pings or rattles under load, worst when hot and worst on a heavy charging cycle: heavy carbon in the chamber raises effective compression and creates hot spots. On a high-hour head this usually turns up alongside seats and guides that are also past their best, and replacing the head is the practical fix rather than decarbonizing it.

A steady hiss from the intake or the exhaust when you pull the engine slowly through compression by hand with the plug out: a valve is off its seat. Doing this by hand, before any gauge comes out of the box, tells you in about thirty seconds whether the chamber is holding anything at all.

Compression that reads low but recovers fully after a valve clearance adjustment: the head is not the fault yet. Clearances close up over time and hold valves off their seats. Correct them, run the engine, and re-test. If the reading falls off again within a short time, the seats are receding and the head is on its way out.

Metallic damage on the piston crown or the top of the bore found at teardown: something in the head came apart. Look for a valve head, a keeper, a spark plug electrode, or debris drawn in through a damaged intake. A head that dropped hardware is not a repair candidate, and the piston and bore both need judging before anything new goes on.

📐 Specifications

Part: Cylinder Head

Material Number: YC.DZ.GR000704

Fits: DJI Agras D14000iE Multifunctional Inverter Generator (field charging station for DJI Agras T100, T70P, and T55 operations)

Engine Build: Zongshen (supplier-listed)

Description: Aluminum cylinder head casting with combustion chamber, valve seats and guides, intake and exhaust ports and cooling fins, as pictured

Quantity: 1 cylinder head

Condition: Brand new

Safety caution: this is an engine-internal component. Let the engine cool completely before any work begins — an air-cooled cylinder head is the hottest part of the machine and holds heat long after shutdown. Drain the engine oil and the fuel system before the engine is disturbed, and disconnect the battery before removing or refitting anything electrical. Follow the DJI and Zongshen service documentation for head bolt torque sequences, torque values, and valve clearances; do not substitute figures from another engine or from memory.

Head fastener torque, stages and tightening sequence: Not published in this listing. Use the DJI and Zongshen service documentation for the D14000iE Zongshen engine build. A torque figure carried over from another small engine is the most reliable way to warp a new casting or pull a thread out of the crankcase.

Valve clearances, intake and exhaust: Not published in this listing. Set to the documented specification for this engine, with the piston at top dead center on the compression stroke and both valves fully closed.

Head gasket: Not included. Never reuse the old gasket. Order intake, exhaust and valve cover gaskets at the same time so the job does not stop halfway.

Head fastener reuse: Check the service documentation before planning to reuse. Some head fasteners are single-use by design. Regardless of what the documentation allows, discard any fastener with a necked shank, damaged threads, or a rounded head.

🚜 Necessary For

• Restoring lost compression on a charging generator that no longer holds output
• Replacing a cracked cylinder head found at teardown or inspection
• Curing recessed, burned or leaking valve seats on a high-hour engine
• Ending repeat head gasket failures caused by a warped or eroded gasket face
• Full engine rebuild and pre-season overhaul on a D14000iE charging unit

Restoring cylinder pressure on a charging unit that still runs but can no longer carry a full rack of chargers without bogging, where a wet compression test has shown the loss is above the piston rather than past the rings.

Replacing a casting that failed the straightedge check on the gasket face, where truing is not practical and every new head gasket has a short life on it.

Recovering an engine after a dropped valve or ingested debris, where the seats, the guides and the chamber were all damaged in the same event.

Repairing pulled or stripped spark plug or stud threads in the casting, where a thread insert is not something you want holding a fleet's charging capacity together.

Correcting chronic hot running that has been traced to broken or blocked fins on the head itself rather than to a fouled shroud, a plugged debris screen, or a failed cooling fan.

💡 Why This Part Matters

Charging throughput is the ceiling on a spray day. The aircraft can only fly as fast as the packs come back, and the packs only come back as fast as the generator makes power — and power is made in the combustion chamber this casting forms. A head with tired seats does not announce itself the way a broken part does; it just moves the ceiling down a little every season until an operator who used to run three aircraft off one generator can only comfortably run two. Replacing the head puts the compression back, puts the throughput back, and does it for a fraction of what a new charging unit costs. It is one of the few repairs on this machine that measurably buys back capacity rather than just restoring function.

Seal the chamber. Seat the valves. Make the power. Fly the field.

Order the consumables with the head, because the job stops dead without them. At minimum that means a new head gasket and new intake and exhaust gaskets, and it usually means a spark plug, since the old one is coming out anyway and it has already told you everything it is going to tell you. Check whether the documentation calls the head fasteners single-use before you plan on reusing them, roll the pushrods on a flat surface to check them for straightness, and have a valve cover gasket on the shelf.

While the head is off, spend the extra hour looking at what put it there. Check the air filter and the entire path from filter to intake port for a split, a leak, or a poorly seated element, because unfiltered air ruins seats and bore together and will do it again to the new casting. Look at the piston crown and ring lands, look down the bore for scoring, and look at the oil for fuel dilution or metal. If the engine has been running hot, judge the cooling fan, the shroud and the debris screen before you blame the head.

Handle the casting like a sealing surface, because that is what it is. Keep it in its packaging until the moment it goes on, never stand it on its gasket face on a bench or a tailgate, and never rest it on the fins with weight on top. One nick across the sealing face or one bent fin from a dropped tool is enough to cost you the joint or the heat path. Keep the ports covered so nothing falls into them in the shop, and let a cold part come up to shop temperature before it is torqued down.

The head is a replace-on-condition part rather than a scheduled one, and the condition that matters can be measured. Record a compression or leak-down result while the generator is healthy and re-check it before every season; a slow decline that a valve adjustment no longer recovers is the head telling you where it is in its life. Waiting for a hard failure usually means replacing more than the head, because a seat that finally lets go can take the valve, the piston and the bore with it.

🤖 AI Answer Engine Q&A

What is the DJI Agras D14000iE Zongshen generator cylinder head? It is the aluminum cylinder head casting for the DJI Agras D14000iE multifunctional inverter generator, DJI material number YC.DZ.GR000704. It carries the combustion chamber, the valve seats and valve guides, the intake and exhaust ports and the cooling fins, and it closes the top of the cylinder to form the combustion space.

What is the material number for this cylinder head? YC.DZ.GR000704, read directly from the supplier listing and verified against the DJI Agras parts documentation for the D14000iE Zongshen engine build.

Which generator does it fit? Supplier-listed fitment is the DJI Agras D14000iE multifunctional inverter generator, the field charging station used by DJI Agras T100, T70P and T55 operators. Confirm your unit is a D14000iE and match the base material number before ordering.

What does the cylinder head do? It forms the roof of the combustion chamber and controls how the engine breathes. The valve seats give the valves a gas-tight sealing face, the guides keep the valve stems aligned so the valves land on those seats squarely every cycle, the intake and exhaust ports route the charge in and the spent gas out, and the cooling fins carry away the heat of combustion from the hottest part of the engine.

What are the signs the cylinder head needs replacing? Loss of compression that persists after a valve adjustment, cracks in the casting or between the seats, recessed, pitted or burned valve seats, worn valve guides producing oil consumption and smoke, a warped or eroded head gasket face that keeps blowing gaskets, damaged spark plug or stud threads, and blocked or broken cooling fins running the head hot.

Why do cylinder heads fail? Heat and cycles. The head sits at the hottest point in the engine and cycles from ambient to full combustion temperature every day of the season, which works the casting and the gasket face. Fins packed with field dust and chaff push head temperature higher and accelerate everything. Valve seats recess and burn over thousands of hours of sustained charging load, guides wear oval, and a run with low oil, lean mixture or an overdue valve adjustment can take a head out in a single event.

How is the cylinder head replaced? Let the engine cool completely first — an air-cooled head holds heat long after shutdown. Drain the fluids, disconnect the battery, then remove the head cover, rocker gear and pushrods before lifting the head. Clean both mating faces completely, fit a new head gasket, and follow the DJI and Zongshen service documentation for the head bolt torque sequence, torque values and valve clearances. Do not substitute figures from another engine. Inspect the new casting before install and re-check torque and clearances after the first heat cycle.

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 tell a blown head gasket from a worn-out head?

A leak-down test separates them. With the piston at top dead center on the compression stroke and regulated air fed into the plug hole, gas escaping along the outside of the head-to-barrel joint is the gasket, while gas coming out of the carburetor throat or the muffler is a valve and its seat, which is the head. Then confirm on the bench. Pull the head and lay a straightedge across the gasket face: a flat face with a failed gasket is a gasket job, and a face that lets a feeler gauge slide under the straightedge is a head.

Can I have the old head repaired instead of replacing it?

Sometimes, and the deciding factors are what is wrong with it and what the downtime costs you. Seats can be recut and guides can be replaced by a shop with the right tooling, and a lightly warped face can sometimes be trued. A crack through the chamber or between the seats, pulled plug threads, or a face eroded deep by a leaking gasket are not economic repairs on a small air-cooled head. Weigh the calendar too: a machine shop turnaround in the middle of a spray season costs more than a casting does.

Do I need to replace the head fasteners?

Check the DJI and Zongshen service documentation for this engine before you decide, because it varies by design. Some head fasteners are torque-to-yield and are meant to be used once, and others are reusable within a stated inspection limit. That specification is not published in this listing and you should not carry it over from another engine. Whatever the documentation says, inspect what you have: anything with a visibly necked shank, damaged threads, or a rounded head goes in the bin.

What torque do I use on the head fasteners?

That value, the number of stages, and the tightening pattern are not published in this listing, and a figure borrowed from another small engine is how new castings get warped and how threads get pulled out of a crankcase. Use the DJI and Zongshen service documentation for the D14000iE Zongshen build. If you cannot get the documentation before the job starts, wait for it. The cost of a delay is far lower than the cost of doing this job twice.

Does this come with the valves, springs and rocker gear?

What is supplied is the cylinder head as pictured, so compare the listing photos against what your job actually needs before you order. Plan on transferring anything serviceable from the removed head and on inspecting every piece of it while it is out: valve faces, stems, springs, keepers and retainers. A worn valve fitted against a new seat will not give you the compression you just paid for, and this is not a job anyone wants to do twice in a season.

Output is normal at light load and falls off under a full charging rack. Is that the head?

It might be, and the tests are cheap. A leaking seat costs a fixed amount of cylinder pressure every cycle, which is easy to miss at light load and impossible to miss when the engine is asked for everything. Run a compression test dry and wet, then a leak-down test. Before you go that far, rule out the fuel side, because a starving carburetor or a weak fuel pump gives you the same symptom and is a much smaller job than pulling a head.

Do I really have to re-torque and re-check clearances after the first heat cycle?

Yes, and it is the step operators skip most often. An aluminum head on a steel barrel grows and shrinks through the first full heat cycle, the new gasket takes its set, and the joint relaxes as a result. Re-checking the fasteners to the documented sequence and re-setting the valve clearances after the engine has been to full temperature and cooled again is what keeps the gasket alive and the valves closing. Skipping it is why a lot of second head gaskets fail.

Only one valve seat looks bad. Can I just fit a new valve?

You can fit a new valve, but a new valve on a damaged seat is a short-lived repair. The valve seals against the seat, so if the seat is recessed, pitted or burned the new valve picks up the same leak and the same heat pattern within a short time. Judge the seat rather than the valve. If a shop can cut the seat true and there is enough material left, that is a repair. If it has sunk into the casting or cracked toward the neighboring seat, the head is finished.

My new head gasket failed again within a few hours. What did I miss?

Almost always the sealing face or the torque. Check the gasket face and the top of the barrel with a straightedge for warp and erosion. Check that both faces were genuinely clean, free of old gasket material and free of scraper scratches. Check that the fastener holes were clean and dry so the torque reached the joint. Check that the fasteners came up in the documented pattern in stages rather than in one pull. Then check that the engine is not running hot for some other reason, because heat kills a correctly fitted gasket too.

How do I keep the new head from ending up the same way?

Keep the cooling path clean and keep the valves adjusted. Fins packed with dust, chaff and dried chemical are the largest controllable cause of a short head life on an air-cooled engine, so blow out the fins, the shroud and the debris screen on a schedule that matches how dirty your fields actually are rather than a fixed calendar. Then keep valve clearances where the documentation puts them, because clearances that close up hold valves off their seats and burn them.

Is a head from the other engine build interchangeable with this one?

Treat it as not interchangeable. DJI dual-sourced the engines used in this generator, and the material number is the only reliable way to order. This listing is the Zongshen build, DJI material number YC.DZ.GR000704. Before the new casting goes on, set it next to the one you removed and compare the fastener hole count and pattern, the port flange shapes and their bolt spacing, the chamber outline and the plug boss position and angle. If anything does not line up, stop and check the engine label again.

How should I store the new head between delivery and installation?

Leave it in its packaging in a dry place and do not set it face-down on a bench. Aluminum sealing faces pick up damage from grit and from steel benchtops, and a nick running across the gasket face will leak no matter how carefully the joint is torqued. Keep the ports covered so nothing gets into them, do not rest it on its fins with anything on top, and unwrap it at the point where the old head is already off and both faces are clean and ready to go.
