Overview
The ZF 0501.217.916 油冷 (oil cooler) is a critical thermal management component engineered for heavy-duty construction machinery transmissions. Positioned within the transmission’s hydraulic circuit, this OEM genuine part dissipates excess heat generated during high-torque operations, ensuring the transmission fluid remains within optimal temperature ranges. The SKU 0501.217.916 specifically refers to a plate-type oil cooler designed to withstand extreme pressure and vibration common in earthmoving equipment. By maintaining proper fluid viscosity, this part directly prevents premature wear on clutches, bearings, and seals.
Symptoms of Failure
When the ZF 0501.217.916 油冷 begins to degrade, operators will notice distinct performance issues. Look for these specific failure indicators:
- Transmission oil leaks around the cooler core or fittings – Visible drips or puddles of ATF fluid under the machine, often accompanied by a burnt smell.
- Erratic gear engagement or slipping under load – The transmission hesitates or fails to hold gears when pushing heavy material, caused by overheated, degraded fluid.
- Persistent high-temperature warnings on the dashboard – The cooler cannot shed heat effectively, leading to frequent over-temp alarms even during moderate operation.
- Contaminated or discolored transmission fluid – Dark, gritty oil that appears “cooked” indicates the cooler has failed to regulate temperature, accelerating fluid breakdown.

Compatibility
This oil cooler is designed for ZF’s heavy-duty powershift transmission series commonly used in construction machinery. Based on the part type and OEM catalog data, the 0501.217.916 is compatible with the following ZF transmission models:
- ZF WG180 – Used in wheel loaders and graders
- ZF WG200 – Common in articulated dump trucks and excavators
- ZF WG210 – Found in heavy forklifts and telehandlers
- ZF 4WG-200 – Older generation powershift transmissions
Always verify your transmission’s serial number against the OEM parts list before installation. This genuine part is not a universal fit for all ZF models; it is specifically engineered for the WG series with a 油冷 mounting bracket.
