It is the alternator and the flywheel at the same time, and it does not want to come off — it is held by its fit on the crank and pulled hard toward the stator by its own magnets. This is the tool that takes it off without wrecking it. Without the right puller you are standing in front of a job you cannot finish and a rotor you can very easily ruin.\u003c\/p\u003e\n\u003cp\u003eA rotor and a stator are two of the most expensive items in the generator, and a bad pull can take out both plus the crankshaft end they sit on. Jaw pullers gripping the magnet ring crack magnets and hubs, prying distorts the stator laminations, heat demagnetizes the rotor, and improvised bolts strip the hub threads or bugger the crank. Owning the correct tooling turns stator, ignition and crank seal work into an ordinary bench job you can do once, properly, and repeat next season.\u003c\/p\u003e\n\u003cp\u003eThat is why Ares Acres keeps hard-to-find OEM generator alternator and ignition components in stock and shipped fast to the U.S.A., helping operators get the rotor off cleanly and finish the repair, minimize downtime, and keep their aircraft spraying when every acre counts.\u003c\/p\u003e\n\u003cp\u003eFor professional farmers, aerial applicators, and commercial drone operators, this is the difference between a generator you can actually service and one that has to leave the farm.\u003c\/p\u003e\n\u003cp\u003eAres Acres also ships genuine DJI OEM parts to Canada, with free shipping included on Canadian orders.

DJI catalogs the alternator on this build as two parts: the magneto stator, YC.DZ.GR000014, and the magneto rotor, YC.DZ.GR000015. Magneto naming means a permanent-magnet outer-rotor machine — the rotor is a magnet-lined bell mounted directly on the crankshaft, spinning around a fixed inner stator. There is no separate flywheel in the parts list because the rotor is the flywheel. At the generator's rated 3600 rpm, that assembly is what turns engine rotation into the raw AC the inverter converts.\u003c\/p\u003e\n\u003cp\u003eThat construction is exactly what makes removal a tooling job rather than a wrench job. The rotor seats on the crankshaft with an interference fit that will not simply slide off, and its magnets pull it hard toward the stator the whole time you are trying to separate them. The correct approach is a jackscrew puller: the tool threads into the rotor hub, a centre forcing bolt bears on the end of the crankshaft, and turning that bolt breaks the fit with straight axial force while the crankshaft is held against rotation. Force goes through the hub, on the axis, in one controlled direction.\u003c\/p\u003e\n\u003cp\u003eEvery alternative applies force somewhere the rotor was not designed to take it. A two-jaw or three-jaw puller grips the magnet ring and cracks magnets or the hub. Prying between rotor and stator bends laminations and destroys the air gap. Heating the hub risks demagnetizing the rotor outright. Hammering drives the crankshaft into its main bearings. None of those are cheap mistakes on this machine.\u003c\/p\u003e\n\u003cp\u003eBuy the tool once.

Magneto stator replacement sits directly behind the rotor. So does ignition work — the ignition coil, YC.DZ.GR000018, and the ignition trigger, YC.DZ.GR000021, which is the crank position pickup the EFI control board times the whole engine from. So does the crankshaft oil seal at that end, and separating the engine from the generator end for deeper work. If the rotor will not come off, none of those jobs start.\u003c\/p\u003e\n\u003cp\u003eThis is also a tool you buy before you need it, not after. A rotor pull is not a roadside repair; it is bench work you schedule, usually in the off-season or the moment a charging fault turns out to be the stator rather than the inverter. Operators who wait until the machine is apart discover that the tool is a low-volume item, and the generator sits open while it ships. Crews running a single D12000i behind a whole fleet should treat this the same way they treat a spare filter kit.\u003c\/p\u003e\n\u003cp\u003eGoing without the correct puller costs you:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eA generator sitting apart on the bench waiting on tooling\u003c\/li\u003e\n\u003cli\u003eCracked magnets or a split hub from a jaw puller on the magnet ring\u003c\/li\u003e\n\u003cli\u003eBent stator laminations and a ruined air gap from prying\u003c\/li\u003e\n\u003cli\u003eA demagnetized rotor from heating the hub to free it\u003c\/li\u003e\n\u003cli\u003eStripped hub threads or a damaged crankshaft end\u003c\/li\u003e\n\u003cli\u003eMain bearing damage from hammering on the crank\u003c\/li\u003e\n\u003cli\u003eA stator and rotor bill that dwarfs the cost of the tool\u003c\/li\u003e\n\u003cli\u003eA repair that has to leave the farm and come back weeks later\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eStraight force, on the axis, through the hub.

The magneto rotor is a permanent-magnet bell mounted on a crankshaft fit, and it comes off one way: straight, on the axis, pulled through the hub. Jaw pullers that grip the magnet ring concentrate load exactly where the rotor is weakest and crack magnets or the hub itself. Prying between rotor and stator bends laminations and ruins the air gap the machine's output depends on. Heat applied to free a stubborn hub risks permanently demagnetizing the rotor, which is not repairable. Hammering transfers the whole blow through the crankshaft into the main bearings. Every one of those is a several-hundred-dollar mistake made to avoid buying one tool.\u003c\/p\u003e\n\u003cp\u003eThis is bench work on a cool, shut-down machine with the starting battery disconnected and fuel handled carefully. Gain access to the alternator end, photograph the wiring, routing and any timing or index references before you disturb anything, and remove the rotor's retaining hardware. Hold the crankshaft against rotation, thread the tool into the rotor hub, then turn the centre forcing bolt steadily against the crankshaft end until the fit releases — support the rotor as it comes free, because it will pull hard toward the stator right up to the moment it lets go. Keep the rotor and the stator bore clean and away from steel debris while they are apart, and reassemble to the same references you photographed, then run the generator and confirm charging output under real load.\u003c\/p\u003e\n\n\n\u003chr\u003e\n\u003ch2\u003e📐 Specifications\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eDJI Material Number:\u003c\/strong\u003e

It is a reusable workshop tool rather than a wear part, and it is the gateway to nearly all alternator and ignition work on that machine. It applies controlled axial force through the rotor hub so the rotor releases without damage to itself, the stator or the crankshaft.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does it fit, and why is a special tool needed at all?\u003c\/strong\u003e It fits the RATO engine build of the DJI Agras D12000i \/ D12000iE generator, which charges T50, T40 and T30 flight batteries. DJI catalogs that alternator as a magneto stator, YC.DZ.GR000014, and a magneto rotor, YC.DZ.GR000015 — a permanent-magnet outer-rotor machine where the rotor mounts directly on the crankshaft and doubles as the flywheel. It seats on an interference fit and its own magnets pull it toward the stator, so it needs a puller that loads the hub rather than the magnet ring.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMy D12000iE has a different engine than my neighbor's. Does that matter?\u003c\/strong\u003e It matters completely. DJI dual-sourced this generator, so some machines carry a RATO engine and some a ZONGSHEN, and the two builds carry separate material numbers right through the alternator. The RATO engine assembly is YC.DZ.GR000020 and the ZONGSHEN engine assembly is YC.DZ.GR000011. This tooling, YC.DZ.GR000375, is the RATO item — read the engine label first and send us a photo if it is unclear.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat jobs actually require pulling the rotor?\u003c\/strong\u003e Anything behind it. Magneto stator replacement, ignition coil work, replacing the ignition trigger that gives the EFI control board its crank position signal, servicing the crankshaft oil seal at that end, and separating the engine from the generator end for a deeper rebuild. If a charging fault has been traced past the inverter to the alternator, this is the first physical step of the repair.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the tool work?\u003c\/strong\u003e It is a jackscrew puller. The tool threads into the rotor hub to take hold of the rotor properly, then a centre forcing bolt bears against the end of the crankshaft, and turning that bolt converts wrench torque into steady axial force that breaks the fit. The crankshaft is held against rotation while you do it. Force stays on the crank axis and travels through the hub, which is the only part of the rotor built to take it.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat goes wrong when people improvise?\u003c\/strong\u003e Two-jaw and three-jaw pullers grip the magnet ring and concentrate load exactly where the rotor is weakest, cracking magnets or the hub. Prying between rotor and stator bends the stator laminations and ruins the air gap the machine's output depends on. Applying heat to free a stubborn hub risks permanently demagnetizing the rotor, which cannot be repaired. Hammering drives the blow through the crankshaft into the main bearings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow do I know I need this before I start?\u003c\/strong\u003e If the repair is on the alternator or ignition end of the engine, you need it — the rotor has to come off before any of that work begins, and it will not release by hand. Confirm the engine is the RATO build from the engine label, and check whether the rotor has been off before, because a generator that has run several seasons outdoors will have corrosion in the joint and will be considerably tighter than a newer one.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the job and its verification look like?\u003c\/strong\u003e Work on a cool, shut-down machine with the starting battery disconnected and fuel handled carefully. Photograph the wiring, routing and any index references before you disturb anything, remove the rotor's retaining hardware, hold the crankshaft against rotation, thread the tool into the hub and turn the forcing bolt steadily until the fit releases — support the rotor, because it pulls hard toward the stator until the moment it lets go. Keep the rotor and stator bore clean and away from steel debris, reassemble to the references you photographed, and verify by running the generator and confirming charging output under real load.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eShould I buy this before I need it?\u003c\/strong\u003e Yes, if you service your own generators. A rotor pull is scheduled bench work, not a roadside repair, and the tool is a low-volume item rather than a fast-moving consumable. Operators who wait until the generator is already apart end up with the machine open while tooling ships.
