A valve train tick is the symptom operators notice, and it has three common sources: clearance that has simply drifted, a worn rocker, or a worn lifter and pushrod underneath it. Pull the valve cover with the engine cold, bring that cylinder to top dead center on the compression stroke so both valves are shut, and check the clearance with a feeler gauge. A reading that is out of spec while the rocker still feels tight and smooth points at adjustment, not at the part.\u003c\/p\u003e\n\u003cp\u003eRead the wear on the pad, which is the face that pushes the valve stem. Wipe it clean and run a fingernail across it. A polished flat area with no step is normal service wear. A dish you can catch a nail in, a groove that follows the stem tip, or a bright edge where the pad has started to break up means the rocker is losing lift and giving it back to the valve as noise. Once the pad is dished, clearance will not hold, because every adjustment is measured against a surface that keeps moving.\u003c\/p\u003e\n\u003cp\u003eCheck the pivot for play with the valve closed and the clearance slack. Hold the rocker and try to lift it and rock it sideways. Free lateral movement, a rattle, or a rocker that wants to sit crooked on its pivot means the bore or the pivot surface has worn oval, and that play shows up as noise the moment the cam loads it. A rocker with a good pad but a loose pivot is still a replacement, because the geometry it swings through is no longer the one the engine was built with.\u003c\/p\u003e\n\u003cp\u003eSeparate a rocker tick from the other noises the generator makes. On a four stroke engine the camshaft turns at half crank speed, so a valve train event repeats once every two crankshaft revolutions and the tick times out slower than anything driven directly off the crank. Listen at the valve cover with a length of hose or a long screwdriver against your ear, then repeat the same test at the crankcase. Noise that is loudest at the cover and slower than engine speed is valve train.\u003c\/p\u003e\n\u003cp\u003eWhen the complaint is lost output rather than noise, use a compression or leak down test to decide whether a valve is involved at all. A rocker that has seized on its pivot, or clearance closed up so tight the valve never fully seats, shows as low compression on that cylinder and, on a leak down, as air escaping through the intake or the exhaust rather than into the crankcase. If compression is even and the leak down is clean, stop looking at the valve train and look at fuel, ignition, and the generator side.\u003c\/p\u003e\n\u003cp\u003eDo not clear the rocker without rolling the pushrod. Lay it on a flat surface such as a piece of glass or a machined table and roll it slowly while you watch the gap underneath. A pushrod that is even slightly bent will lift at the middle, and a bent pushrod both causes rocker wear and hides it, because the rocker is being loaded off axis on every cycle. Check the cup end and the ball end for the same dishing you looked for on the rocker pad.\u003c\/p\u003e\n\u003ch2\u003e⚙️ Functional Purpose\u003c\/h2\u003e\u003cp\u003eThe rocker actuates the valve. A worn rocker or pivot throws off valve timing and clearance — valve-train noise, lost power, and accelerated wear on the valve and seat.\u003c\/p\u003e\u003cp\u003eMake the engine safe and clean before anything comes apart. Let it cool fully, shut off the fuel, isolate the starting battery, and give the top of the engine a proper clean around the valve cover joint. Anything sitting in that seam falls straight into the head and the pushrod tunnels as soon as the cover lifts, and grit that reaches an oil passage or a lifter costs far more than the rocker you came to change.\u003c\/p\u003e\n\u003cp\u003eTake the cover off evenly and keep the fasteners in order. Loosen the valve cover screws in stages rather than pulling one out completely first, since a cover held at one corner distorts and the gasket takes the load. Set the screws down in the pattern they came out of if the lengths differ. Expect the gasket to be stuck, and ease it free rather than levering against the sealing face of the head, which is soft enough to nick and hard to make good again.\u003c\/p\u003e\n\u003cp\u003eUnload the rocker before you touch a fastener. Turn the engine over by hand in its normal direction until the cylinder you are working on sits at top dead center on the compression stroke, where both valves are closed and both rockers are free. Slackening a rocker while the cam is lifting it puts the whole spring load through the fastener and the pushrod, and that is how a pushrod ends up bent by the person trying to replace the part it damaged.\u003c\/p\u003e\n\u003cp\u003eKeep everything paired and oriented. If the engine uses separate intake and exhaust rockers they are not interchangeable, and even where they look identical each one has bedded to its own pushrod and its own valve tip. Lay the parts out in the order they came off, keep each pushrod with its own bore, and note which way the rocker faced. Refitting a used rocker backwards puts a fresh contact patch onto a worn pad and it will hammer.\u003c\/p\u003e\n\u003cp\u003eAssemble wet, not dry. Oil the pivot, the pad, and the pushrod sockets with clean engine oil before anything goes back, because the first seconds after a start are when a dry pivot picks up. Seat the pushrod into the lifter cup at the bottom and into the rocker socket at the top, and confirm both by feel before you tighten anything. A pushrod sitting on the rim of a cup rather than in it will look right, then bend on the first turn of the engine.\u003c\/p\u003e\n\u003cp\u003eSet the clearance last, and check your own work twice. With the cylinder still at top dead center on compression, set the gap to the figure DJI and Zongshen publish for this engine, using a feeler gauge that pulls through with light drag. Hold the adjuster still while you tighten the locknut, then measure again, because the adjuster almost always moves as the nut pulls down. Turn the engine over two full revolutions by hand, return to top dead center, and confirm the gap has not changed.\u003c\/p\u003e\n\u003cp\u003eClose it up and prove it before the generator goes back to work. Fit a fresh valve cover gasket if the old one has taken a set, run the cover fasteners down in a crossing pattern rather than pulling one corner tight, and wipe the joint dry so any weep is obvious later. Start the engine, let it reach normal running temperature, then listen again and look for oil at the cover. A tick that returns as the engine warms means the clearance was set on a cold guess rather than to spec.\u003c\/p\u003e\n\u003ch2\u003e⚠️ Common Replacement Indicators\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eValve-train tick or tap noise\u003c\/li\u003e\n\u003cli\u003eValve clearance out of spec\u003c\/li\u003e\n\u003cli\u003eWorn rocker face or pivot\u003c\/li\u003e\n\u003cli\u003ePower loss\u003c\/li\u003e\n\u003cli\u003eRough running\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eConfirm before you order:\u003c\/strong\u003e this part is DJI number YC.DZ.GR000237, 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.\u003c\/p\u003e\u003cp\u003eA tick that is loud on a cold start and fades as the engine warms is usually clearance sitting at the wide end of tolerance rather than a failed rocker. Metal grows as it heats and the gap closes. It is still worth investigating, because a gap that is wide when cold means the parts have already given up material somewhere, but at that stage the fix is often an adjustment and an inspection rather than a new part.\u003c\/p\u003e\n\u003cp\u003eA tick that is quiet cold and gets louder as the engine comes up to temperature and takes load points the other way. That pattern fits a worn pad or a slack pivot, where the noise comes from parts moving against each other rather than from a measured gap. Heat and cylinder pressure make a loose rocker rattle more, not less, so a noise that grows with the workload is the one to take seriously.\u003c\/p\u003e\n\u003cp\u003eClearance that will not stay set is the clearest single sign this part is finished. If you adjust to spec, run the generator for a few hours, and find the gap has opened again, material is coming off somewhere in that chain, and the rocker pad is the most common place. Adjusting a second time simply moves the same problem further along and takes lift away from the valve each time you do it.\u003c\/p\u003e\n\u003cp\u003ePower that falls away under load with no misfire and no fuel or ignition fault often means a valve is not opening as far as it should. A worn rocker gives back part of its lift as noise and lost motion, the cylinder breathes less, and the generator runs out of headroom exactly when the aircraft is asking for the most from it. The engine may idle perfectly and still be short of output at the point where it matters.\u003c\/p\u003e\n\u003cp\u003eRough running that is worse at low speed and cleans up as revs rise can come from clearance closed up rather than opened out. A valve held slightly off its seat leaks compression at cranking and low speed, where there is time for pressure to bleed away. If one cylinder is hard to start when hot, check the clearance on that cylinder before assuming a fuel problem and chasing it through the fuel system.\u003c\/p\u003e\n\u003cp\u003eBright metal in the oil or on the drain plug magnet after a top end noise turns up is a reason to stop and look properly. Fine glitter is normal wear over time, but flakes or slivers mean a hard surface is breaking up, and a rocker pad, a pushrod tip, or a lifter face are the usual sources. Replacing the noisy rocker without finding where the metal came from just puts a new part into a dirty engine.\u003c\/p\u003e\n\u003ch2\u003e📐 Specifications\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eDJI Material Number:\u003c\/strong\u003e YC.DZ.GR000237\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003ePart:\u003c\/strong\u003e Generator Valve Rocker\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eFits:\u003c\/strong\u003e DJI Agras D14000iE generator (T100 \/ T70P), Zongshen engine (supplier-listed fitment)\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eEngine:\u003c\/strong\u003e Zongshen\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCondition:\u003c\/strong\u003e Brand new\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eValve Clearance Figure:\u003c\/strong\u003e Not published in this listing.

Read the number off the part you removed character by character against the number in this listing rather than scanning it. YC.DZ.GR000237 is the rocker, and a near neighbor in the sequence is not.\u003c\/p\u003e\n\u003cp\u003eDo not confuse the rocker with the parts it works against. The pushrod, the adjuster screw and locknut, the rocker pivot or shaft, and the valve cover gasket are separate items with their own numbers, and all of them are commonly disturbed during the same job. A worn pivot and a worn rocker produce much the same noise, so decide which one you actually need before ordering, or order both if the engine is already open.\u003c\/p\u003e\n\u003cp\u003eOn the bench, tell a rocker apart from a similar one by its two working faces rather than by its outline. Look at the pad that meets the valve stem, the socket or ball seat that takes the pushrod, and the pivot bore, then compare the spacing between them. Two rockers can share a silhouette and still swing through different geometry. If the pad and the pushrod socket do not line up when you hold the new part against the old one, it is not the same component.\u003c\/p\u003e\n\u003cp\u003eThis is a generator engine part, not an airframe part. It sits inside the Zongshen engine that drives the generator, so nothing about it is fitted to the aircraft and no message from the aircraft will name it. Operators searching an airframe parts diagram for a valve rocker will not find it there. The generator carries its own parts documentation, and that is where this callout lives.\u003c\/p\u003e\n\u003ch2\u003e💵 What Downtime Actually Costs\u003c\/h2\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eA 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.\u003c\/p\u003e\n\u003cp\u003eAgainst 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFor the D14000iE Zongshen Generator Valve Rocker, that logic is straightforward:\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003chr\u003e\n\u003ch2\u003e💡 Why This Part Matters\u003c\/h2\u003e\u003cp\u003eThe rocker is a small lever doing hard work thousands of times a minute. Worn, it steals valve lift and adds noise. A key valve-train service part that keeps timing honest.\u003c\/p\u003e\n\u003cp\u003eWhile the cover is off, inspect everything the rocker touched. Look at the valve stem tip for a cupped or mushroomed face, at the pushrod for a bend and for dished ends, at the adjuster for a worn ball, and at the pivot for scoring. The rocker rarely wears alone, because whatever destroyed its pad was working on the parts either side of it at the same time. Fitting a new rocker against a worn stem tip simply transfers the wear to the new part.\u003c\/p\u003e\n\u003cp\u003eCheck why the rocker was starved or overworked before you close the engine. Oil that has been left in past its interval, run low, or diluted with fuel loses the film that keeps a pivot alive, and a blocked oil feed to the rocker will kill a new one as fast as it killed the old one. Look at the oil on the dipstick and at the underside of the cover, and if the oil is black, thin, or smells of fuel, deal with that as part of the same job.\u003c\/p\u003e\n\u003cp\u003eAir is the other half of the story. Dust that gets past a poorly seated or overdue air filter travels through the combustion chamber and into the oil, and it laps hard surfaces such as a rocker pad and a valve tip. A generator that spends its life sitting on dry ground beside a spray operation lives in exactly that environment. If the rocker you removed is worn beyond its age, the air filter and its seal are the first place to look.\u003c\/p\u003e\n\u003cp\u003eHandle the new rocker as a precision part rather than a lump of steel. Leave it in its packaging until the moment it goes in, keep it clear of grit on the bench, and do not set it down pad first on a concrete floor. A nick on the pad or in the pivot bore becomes the start of the next failure, because those surfaces run under high contact pressure with only a thin film of oil between them. Oil it before it goes anywhere near the engine.\u003c\/p\u003e\n\u003cp\u003eReplace preventively when the engine is already open, and on evidence otherwise. There is no reason to pull a good rocker out of a running engine, but there is every reason to fit a new one while the cover is off for a clearance service, a head gasket, or a pushrod replacement, because the labor is already spent and the part is small against the cost of going back in. Operators who keep a spare in the truck do it for the same reason.\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.

Set the gap to spec cold, run the generator under a normal load, then measure again. If the gap holds and the tick is gone, the rocker was not the problem and you have saved yourself a part. If the gap has opened again after a few hours, or you could not get a consistent feeler reading because the pad is dished, the rocker is worn, and adjusting it a second time only takes more lift away from the valve.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I tell a worn rocker from a worn lifter or a bent pushrod?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eWork from the top down with the cover off. Check the rocker pad and pivot for a dish or for play first, because they are visible. Then roll the pushrod on a flat surface and look at both ends for dishing. If the rocker and pushrod are good and the noise persists with clearance set to spec, the fault is below them at the lifter or the cam, which is a deeper job than this part. Listening alone will not separate them, so you have to look.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I replace both rockers on a cylinder, or the whole set?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIf one rocker has worn out through age, oil condition, or dirt, its neighbors have lived the same life and are on the same curve. With the engine already open the extra labor is close to nil, so operators who want to close the top end and forget it usually change them together. If the rocker was damaged by a single event such as a bent pushrod or a dropped adjustment, inspect the others carefully and replace only what actually shows wear.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWill the generator or the aircraft throw a code that names the valve rocker?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eNo. Generator and aircraft diagnostics report what they can measure, which is output, engine condition, and fault states, not the condition of individual valve train parts. What you see instead is reduced output under load, harder starting, or rough running, with mechanical noise as the real clue. Diagnosis of this part is done with the cover off, a feeler gauge, and your eyes, not on a screen.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the order include the adjuster screw, locknut, or valve cover gasket?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThis listing itemizes one Generator Valve Rocker, DJI material number YC.DZ.GR000237, and does not state that any adjuster hardware or gasket ships with it. Plan the job accordingly. A valve cover gasket that has been compressed and heat cycled rarely seals well a second time, so order one at the same time rather than finding out after the engine is buttoned up and weeping oil down the block.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I know the new rocker is seated and set correctly before I start the engine?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eThree checks, all by hand. First, confirm the pushrod is down in the lifter cup and up in the rocker socket rather than perched on a rim, by pressing the rocker and feeling for solid contact. Second, turn the engine over two full revolutions by hand and feel for any hard spot, which would mean something is binding. Third, come back to top dead center on compression and confirm the clearance is still what you set after the locknut was tightened.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eThe generator lost power under load but idles fine. Is a worn rocker enough to do that?\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eIt can be, and the way to prove it is a compression or leak down test rather than more listening. A rocker that has lost pad height opens the valve less than it should, the cylinder breathes less, and the shortfall only shows when the engine is asked for everything. On a leak down you would hear air out of the intake or the exhaust on the affected cylinder.
