This generator is air cooled. There is no radiator, no coolant, no thermostat and no reserve — the only thing standing between a hard-working engine and heat damage is moving air, and the only reason air moves is the cooling fan. The mounting plate is what holds that fan in the right place, square, rigid and at the right clearance. It is a small structural part with the entire thermal margin of the machine sitting on it, and when it cracks or loosens nothing warns you until something is already hot.
Heat damage on an air-cooled engine is cumulative and quiet. Airflow falls off, cylinder and head temperatures climb, the oil film thins where it matters most, and the machine keeps running and charging while it wears out early. A shifted fan is worse than a slow one, because a fan running out of position can contact its surroundings, throw itself out of balance and destroy its own bearings on the way. Replacing the plate restores fan position, alignment and rigidity — which is the whole cooling system on this machine.
That is why Ares Acres keeps hard-to-find OEM generator cooling system components in stock and shipped fast to the U.S.A., helping operators restore proper cooling airflow, minimize downtime, and keep their aircraft spraying when every acre counts.
For professional farmers, aerial applicators, and commercial drone operators, this plate is the part that decides whether your charging engine runs cool in July or slowly cooks itself.
Ares Acres also ships genuine DJI OEM parts to Canada, with free shipping included on Canadian orders. Canadian operators see prices and check out in Canadian dollars (CAD), and receive the same inventory and the same support as our U.S. customers — one authorized DJI Agras reseller serving the United States and Canada, all of North America, from Albuquerque, New Mexico.
The DJI Agras T50 OEM D12000i RATO Generator Cooling Fan Mounting Plate is the structural plate that carries the cooling fan in the forced-air cooling path of the RATO-build engine inside the D12000i / D12000iE Multifunctional Inverter Generator — the ground charging unit behind your fleet's flight batteries.
On an air-cooled machine, cooling is a geometry problem before it is anything else. Air has to be moved, and it has to be moved through the fins and past the hot surfaces rather than around them. That means the fan has to sit exactly where the design put it: correct position, correct alignment, correct running clearance, and rigid enough that it stays there under vibration. The mounting plate is what enforces all four. When it distorts, cracks at a boss, or works loose, the fan is still spinning but the air is no longer going where it was supposed to.
The D12000i's thermal envelope is finite and published. DJI rates the machine for operation between −5 and 40 °C and up to 1000 m altitude, running at 3600 rpm and producing 9000 W of DC charging output plus its AC supply. That is a lot of waste heat to shed on open ground in the middle of a spray season, and the machine has no thermal buffer to fall back on. Whatever margin exists lives entirely in airflow.
DJI treats this area as a pre-flight item rather than a hidden internal. The pre-operation checklist tells you to confirm the muffler shield and the fan hood have been securely installed in place and that all the nuts, bolts and screws have been tightened, and to keep flammable material clear from around the muffler and the fan hood. That instruction exists because loose or damaged cooling structure is a real, expected field condition on this machine — not a rare one.
No coolant, no thermostat, no second chance. Just air.
The Cooling Fan Mounting Plate governs:
Commercial charging setups work brutally hard every day, including:
Throughout that service, generator cooling system components are routinely exposed to:
Mounting structure fails by fatigue, and fatigue is patient. Vibration and heat cycling work on the same fastener bosses and the same stress corners day after day until a hairline crack appears, and from there the fan starts to move a little more each hour, which feeds more vibration back into the plate. That is a loop that only accelerates. It usually announces itself as a new noise long before anyone connects it to a temperature problem.
The Cooling Fan Mounting Plate delivers:
Cooling is not a component on this machine. It is a geometry, and this plate holds it.
The Cooling Fan Mounting Plate is designed to hold the cooling fan in exactly the position, alignment and clearance the machine's air cooling depends on, and to keep holding it there under continuous vibration and heat.
The component:
The thing to understand about air cooling is that it has no buffer. A liquid-cooled engine has thermal mass and a temperature gauge that gives you warning. This machine has neither. Airflow either happens or it does not, and the consequences show up as accelerated wear on the parts that live hottest — the cylinder, the rings, the valve train — rather than as a warning light. That is why the cooling structure gets an explicit line in DJI's pre-operation check while plenty of internal parts do not.
It is also why noise is worth taking seriously here. A rattle or buzz that changes with engine speed, a new whine, or a rub you can hear when the machine loads up are all classic signs that something in the cooling assembly has moved. Operators tend to file those under harmless generator noise. On an air-cooled machine carrying a whole fleet's charging duty, a noise that tracks with RPM deserves a look before the next hot afternoon, not after it.
A cracked or loose cooling fan mounting plate costs you:
Hold the fan still and the engine stays cool. It really is that simple.
Time to order when you see:
What kills generator cooling system components is vibration plus heat, in that order. A single cylinder cannot be balanced out, so everything bolted to this engine lives in a constant shaking force, and mounting structure fails by fatigue at fastener bosses and stress corners rather than by wearing out. Radiated heat from the engine and exhaust side cycles the material every single day between a cold dawn start and full charging load, which accelerates that fatigue. Then add the human factors: fasteners over-torqued at service, fasteners left loose, a chaff-loaded fan working harder and feeding more imbalance back into the plate, and trailer transport hammering the whole assembly over rough ground. Corrosion from rain, dew and wash-down finishes off older machines.
Replace with the engine cool and shut down and the starting battery disconnected. Photograph the assembly, the fan orientation, all shrouding and ducting and every fastener position before you disturb anything, because getting the fan back in the same place is the entire point of the job. Inspect the fan itself while it is off — a plate that cracked from imbalance usually took the fan with it, and refitting a damaged fan onto a new plate simply repeats the failure — and clear all accumulated chaff and lint from the cooling path while you have access. Fit the new plate, mount the fan square, and pull the fasteners up evenly to a consistent tension rather than hard. Verify by turning the fan through a full rotation by hand checking for contact at every point, confirming the fan hood is securely installed and all nuts, bolts and screws are tight per DJI's pre-operation check, then running the machine unloaded and listening before you put it back on charging duty.

This component is built for:
Especially valuable during:
When the charging station is down, the aircraft do not fly and the window closes. Cooling structure is cheap right up until the moment it is an engine.
Air is the entire cooling system. Everything else is just holding it in place.
The D12000i works in exactly the conditions that punish air cooling: open ground, no shade, high ambient temperature, and continuous run hours through the hottest weeks of the year. DJI rates it from −5 to 40 °C and up to 1000 m, at 3600 rpm, delivering 9000 W of charging output. Every watt it does not turn into charge, it turns into heat that has to leave through moving air. The fan does that work, and this plate is what keeps the fan able to do it.
The reason to replace rather than repair is that this is a fatigue part carrying a rotating mass. A cracked boss that gets tightened back down will crack again, usually worse, and the imbalance it allows in the meantime feeds straight back into the fan bearings. It is also RATO-build specific: the D12000iE ships with either a RATO or a ZONGSHEN engine, DJI assigned separate material numbers throughout, and the RATO engine assembly is YC.DZ.GR000020 while the ZONGSHEN engine assembly is YC.DZ.GR000011. Confirm the engine label before ordering.
The Cooling Fan Mounting Plate delivers:
Running a damaged fan mounting plate, operators risk:
For practical, hardworking operators, the value is simple:
Check the hood. Check the bolts. Keep the air moving. Keep it flying.

What is the DJI Agras T50 OEM D12000i RATO Generator Cooling Fan Mounting Plate (YC.DZ.GR000043)? It is the genuine DJI structural plate that carries the cooling fan on the RATO engine build of the D12000i / D12000iE Multifunctional Inverter Generator, the ground charging station for DJI Agras T50, T40 and T30 flight batteries. It fixes the fan's position, alignment and running clearance in the machine's forced-air cooling path. On an air-cooled machine that geometry is the cooling system.
What does it fit? It fits the cooling assembly of the RATO engine build of the DJI Agras D12000i / D12000iE generator, and it pairs with the D12000i cooling fan, YC.DZ.GR000044. Because it is an engine-side part it is specific to the generator's engine build rather than to any one aircraft. Confirm your machine carries the RATO engine before ordering.
My D12000iE has a different engine than my neighbor's. Does that matter? 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 throughout. The RATO engine assembly is YC.DZ.GR000020 and the ZONGSHEN engine assembly is YC.DZ.GR000011. This plate, YC.DZ.GR000043, is the RATO part — read the engine label first and send us a photo if it is unclear.
Why does a mounting plate matter this much? Because the generator is air cooled, with no coolant, no thermostat and no thermal reserve. Cooling depends entirely on air being moved through the right surfaces, which depends on the fan sitting in exactly the position and alignment the design intended. When the plate cracks, distorts or loosens, the fan still spins but the airflow no longer goes where it should — and nothing on the panel tells you.
How do I tell the plate is failing? Start with noise. A rattle or buzz from the cooling area that changes with engine speed, a new whine, or a rub under load are the usual first signs. Then look: cracks at the fastener bosses or stress corners, elongated fastener holes, a plate that no longer sits flat, contact or rub witness marks on the fan or hood, or fasteners that will not stay tight no matter how often you torque them.
What causes this part to fail? Vibration and heat. A single-cylinder engine cannot be balanced out, so everything bolted to it lives in a constant shaking force, and mounting structure fails by fatigue at bosses and stress corners rather than by wearing out. Daily thermal cycling from cold start to full charging load accelerates that. Over-torqued or loose fasteners, a chaff-loaded fan feeding imbalance back into the plate, trailer transport over rough ground and corrosion on older outdoor machines all contribute.
How do I confirm the diagnosis before I order? With the engine cool and stopped, try to move the fan assembly by hand and feel for any play at the mount. Turn the fan through a full rotation checking clearance at every point, and look for rub marks on the fan tips, hood and shrouding. Inspect every fastener boss and stress corner under good light for hairline cracks, check whether the plate sits flat, and confirm whether fasteners have been repeatedly retightened — that history alone usually means the structure has already given up.
What does installation and verification look like? Work on a cool, shut-down machine with the starting battery disconnected. Photograph the assembly, fan orientation, shrouding and every fastener position first, because returning the fan to exactly the same place is the point of the job. Inspect the fan itself and replace it if it is damaged, since refitting a damaged fan to a new plate repeats the failure, and clear accumulated chaff and lint from the cooling path while you have access. Fit the plate, mount the fan square, tighten evenly, then rotate the fan by hand through a full turn checking for contact, confirm the fan hood is secure and all fasteners are tight per DJI's pre-operation check, and run the machine unloaded to listen before returning it to charging duty.
What maintenance keeps the cooling system healthy? Do the check DJI actually asks for. Before operation, confirm the muffler shield and fan hood are securely installed and all nuts, bolts and screws are tightened, and keep flammable material clear from around the muffler and fan hood. Beyond that, clear chaff and lint out of the cooling path regularly in dusty conditions rather than waiting for a scheduled interval, and treat any new noise that tracks with engine speed as something to investigate before the next hot day.
