Overview
The ZF 0501.006.137 OIL COOLER is a critical thermal management component designed to regulate hydraulic fluid temperatures within ZF heavy-duty transmissions. Positioned in the transmission’s external cooling circuit, this OEM genuine part dissipates excess heat generated during high-torque operations in construction machinery. By maintaining optimal oil viscosity, the cooler ensures consistent clutch engagement and gear lubrication. The SKU 0501.006.137 is engineered to meet ZF’s exacting tolerances, preventing thermal degradation of seals and friction materials. This part works in concert with the 4108101153: HOUSING to create a sealed fluid pathway, and it interfaces directly with the 0501212152: MOTOR for active fluid circulation.
Symptoms of Failure
When the ZF 0501.006.137 oil cooler begins to fail, operators often notice persistent transmission overheating during moderate loads, a classic sign of restricted coolant flow. Another common symptom is erratic gear engagement or slipping as overheated oil loses its lubricating film strength. Look for visible oil seepage around the cooler core or mounting points, which indicates cracked brazed joints. Finally, contaminated transmission fluid with a burnt odor suggests the cooler is no longer effectively lowering oil temperatures, accelerating wear on the 0735370299: TAPERED ROLLER BEARING and other internal components.

Compatibility
This oil cooler is primarily designed for ZF’s WG series powershift transmissions used in construction machinery. It is a direct fit for the WG180 and WG200 models, commonly found in wheel loaders and graders. It also serves the WG160 and WG210 series when equipped with external cooling loops. Always verify the mounting bracket alignment with the 0501314793: COVER to ensure proper sealing. For specialized applications, cross-reference the transmission serial number with ZF documentation.
