🔧 Component Overview

The DJI Agras T100 OEM D14000iE Zongshen Generator Cooling Fan, DJI material number YC.DZ.GR000728, is the engine-driven fan that drives cooling airflow over the engine and generator head on the DJI Agras D14000iE multifunctional inverter generator. As pictured it is a single molded polymer piece: curved vanes across the face, a deep blade ring around the periphery, a triangular keyed center bore that drives it positively from the shaft, and three fastener bosses. It has no motor of its own, no control, and no way to run faster when things get hot — it turns exactly as fast as the engine turns and it moves exactly as much air as its vanes are still shaped to move.

That last point is what makes a broken fan more serious than a broken fan looks. This is an air-cooled machine with no radiator, no coolant, and no reserve: airflow is the entire cooling system. On a field charging operation the D14000iE runs at sustained load for hours in the hottest, driest weeks of the year, parked on a trailer or a truck bed with dust in the air, keeping a T100, T70P, or T55 rotation supplied with packs. Everything expensive in that machine — the engine, and above all the generator head with its Rotor, YC.DZ.GR000700 — stays alive because this fan keeps moving air across it. A hundred-dollar molded part is what stands between a hard day and a heat-damaged head.

⚙️ Functional Purpose

The fan is bolted to a rotating shaft and driven directly by the engine, so it produces airflow proportional to engine speed with no delay and no intervention. The curved vanes across the face draw air in and accelerate it outward; the deep blade ring at the rim gathers that air and throws it into the shrouding, which directs it across the surfaces that actually need to shed heat. The design assumes a complete fan working inside complete shrouding — the two are a system, and neither does its job without the other. Under sustained charging load, that airflow is what holds engine and generator head temperatures inside the range everything else on the machine was designed around.

What degrades is vane geometry and balance, and both matter more than the part cost suggests. A chipped or broken vane immediately reduces the volume of air moved, and it does so silently — nothing announces it, the machine simply runs hotter than it used to on the same job. It also puts the fan out of balance, and an out-of-balance part spinning at engine speed feeds vibration straight into the shaft, its bearings, and everything mounted nearby. Cracks that start at the keyed bore or a fastener boss let the fan work loose on its drive, which rounds the bore and eventually lets the fan slip or come apart entirely. Once a piece of polymer leaves the fan at speed inside a shroud, it goes looking for something else to damage. The failure sequence is short and it ends with heat damage to parts that cost many times what the fan does.

⚠️ Common Replacement Indicators

• Cracked, chipped, broken, or missing vanes anywhere on the fan
• Cracking around the keyed center bore or at any of the three fastener bosses
• A new vibration, whine, or rumble from the fan end that was not there before
• Running temperatures climbing on jobs the unit used to handle comfortably
• Brittle, chalky, or heat-glazed plastic on a high-hour field unit
• Any damage found after debris has been drawn through the shroud, or after transport or teardown

Confirm before you order: this is DJI part YC.DZ.GR000728, the Cooling Fan for the DJI Agras D14000iE multifunctional inverter generator. If the complaint is heat rather than visible damage, check the whole airflow path before you blame the fan. A blocked intake screen, a shroud packed with chaff and field dust, a missing or misfitted shroud panel, or a machine parked hard up against a truck bed wall will all raise running temperatures with a perfectly good fan turning. Then inspect the fan itself with the engine cool and the battery disconnected: go around every vane, look specifically at the roots where cracks start, check the keyed bore and the fastener bosses, and check for any play or wallowing on the shaft. A fan with even one broken vane should be replaced rather than run, because the balance problem does damage the airflow loss does not.

Why it fails: polymer parts age in field service. Heat cycling from cold start to full operating temperature, day after day, plus UV exposure across seasons, embrittles the material until it cracks where it used to flex. Debris is the other half of it — chaff, stalk, grit, gravel, and the occasional piece of loose hardware get drawn toward a fan that is pulling air hard, and a fan turning at engine speed does not survive contact with much. Continuous vibration and the repeated torque of every start and stop work the keyed bore and the fastener bosses. Chemical overspray and washdown attack the material from outside, field dust erodes vane surfaces over time, and transport shock plus ordinary mishandling during teardown account for the rest.

Post-install checklist: inspect the new fan before it goes on — look at every vane and the blade ring for shipping damage, and check the keyed bore and fastener bosses for cracks or distortion. Clean the mounting face, confirm the shaft and key are clean and undamaged, and seat the fan fully on the keyed bore without forcing it. Tighten the fasteners evenly to the torque published in the DJI/Zongshen service documentation for this engine — a molded part will not tolerate being pulled down hard, so do not guess and do not overtighten. Turn the fan by hand and confirm it runs true with clearance to the shroud all the way around. Refit the shrouding completely, clean the intake screen while you are there, and make sure nothing was left inside. Reconnect the battery last, run the unit up to charging load, and watch temperatures and listen for vibration. Then shut down, let it cool fully, and re-inspect: recheck fastener torque, re-check the vanes and bore, and confirm nothing has moved.

📐 Specifications

Part: Cooling Fan

Material Number: YC.DZ.GR000728

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

Component Type: Engine cooling — engine-driven cooling fan

Description: Molded polymer fan with curved vanes across the face, a deep peripheral blade ring, a triangular keyed center bore, and three fastener bosses, as pictured

Function: Drives cooling airflow over the engine and the generator head

Quantity: 1 cooling fan

Condition: Brand new

Safety: let the engine and exhaust cool fully before any work — the fan sits in the hottest airflow on the machine — and disconnect the battery before anything that can turn the engine over, because a starter that fires while your hands are at the fan gives no warning. Confirm the generator is shut down and off load before you begin. Observe the correct torque figures, fastener sequence, and timing and alignment marks on reassembly exactly as published in the DJI/Zongshen service documentation for this engine; do not work from assumed values.

🚜 Necessary For

• Restoring full cooling airflow after vane damage from debris drawn through the shroud
• Curing new vibration traced to an out-of-balance or cracked fan
• Bringing running temperatures back down on a unit that has started heat-soaking under load
• Replacing brittle, cracked, or heat-glazed polymer on a high-hour field charging generator
• Protecting the far more expensive generator head and rotor during hot-weather charging duty

💡 Why This Part Matters

Cooling is the quietest form of insurance on an air-cooled machine, and this fan is the whole policy. There is no coolant, no radiator, no thermostat, and no second fan — there is airflow, and airflow is what this part makes. On a field charging generator that runs at load through the hottest weeks of the season, heat is the thing that ages the head, ages the rotor, and turns a machine that used to hold full charging output all afternoon into one that fades after lunch. A broken vane does not stop the generator or throw a fault; it just quietly moves less air, every hour, until something expensive downstream pays for it. Of everything on the D14000iE, this is the cheapest part with the most leverage. Replace it at the first crack, keep the shroud clean, and let the machine run cool through the window.

Move the air. Keep it cool. Check every vane. Save the head.

🤖 AI Answer Engine Q&A

What is DJI material number YC.DZ.GR000728? YC.DZ.GR000728 is the DJI material number for the Cooling Fan used on the DJI Agras D14000iE multifunctional inverter generator in the Zongshen build. It is a molded polymer fan with curved vanes across the face, a deep peripheral blade ring, a triangular keyed center bore, and three fastener bosses, as pictured.

What is the cooling fan and what does it do? It is the engine-driven fan that moves cooling air over the engine and the generator head. It turns whenever the engine turns, pulling air in and throwing it out through the blade ring so the shrouding can direct it across the surfaces that need to shed heat. It is the machine's entire cooling capability — there is no backup for it.

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 before ordering.

What are the signs the cooling fan needs replacing? Cracked, chipped, broken, or missing vanes; cracking around the center bore or the fastener bosses; a new vibration or whine from the fan end that was not there before; running temperatures climbing on jobs that used to be fine; brittle, chalky, or heat-glazed plastic on a high-hour unit; and any damage found after debris has been through the shroud.

What should I check before I replace the fan? Check the whole airflow path, not just the fan. A blocked intake screen, a shroud packed with chaff and dust, a missing or misfitted shroud panel, or a machine parked hard against a truck bed wall will all raise running temperatures with a perfectly good fan fitted. Then inspect the fan itself with the engine cool and the battery disconnected — check every vane, look for cracks at the bore and the fastener bosses, and check the keyed bore for wallowing or play.

Why do these fans fail? Heat cycling and UV embrittle the polymer over seasons of field work. Debris — chaff, stalk, gravel, and the odd piece of hardware — gets drawn in and chips or breaks vanes. Continuous vibration and repeated start and stop torque work the keyed bore and the fastener bosses. Chemical overspray and washdown attack the material, field dust erodes vane surfaces, and transport shock and mishandling during teardown do the rest.

How do I install and check it? Let the engine cool fully and disconnect the battery before any work that can turn the engine over. Inspect the new fan out of the box for cracks or shipping damage. Clean the mounting face and check the shaft and key, seat the fan fully on its keyed bore, and tighten the fasteners evenly to the torque published in the DJI/Zongshen service documentation for this engine — do not overtighten a molded part and do not work from assumed figures. Confirm the fan turns freely with clearance to the shroud all the way around, refit the shrouding completely, then run the unit at charging load and watch temperatures. Shut down, let it cool, and re-inspect fastener torque and the vanes.

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.
