ZF 2094.301.050 COVER | OEM Genuine Part

Overview

The ZF 2094.301.050 COVER is a critical OEM genuine component designed to seal and protect the internal mechanisms of heavy-duty construction machinery transmissions. Positioned on the exterior of the transmission housing, this cover prevents contaminants from entering the gear train while maintaining proper oil pressure within the system. The SKU 2094.301.050 is engineered to exact ZF tolerances, ensuring a precise fit that safeguards adjacent assemblies. This part works in concert with the 2094101017 TRANSMISSION HOUSING and the 2094301069 HOUSING to form a sealed environment for rotating components, making it indispensable for transmission integrity in excavators, loaders, and graders.

Symptoms of Failure

When the ZF 2094.301.050 COVER deteriorates, operators may notice several distinct failure indicators. Oil seepage around the cover perimeter is the most common symptom, often visible as wet spots on the transmission exterior. Contaminated transmission fluid can occur if the cover cracks, allowing dirt and moisture to bypass the seal. Abnormal gear noise or vibration may develop if the cover loosens, altering internal pressure dynamics. In severe cases, erratic shifting or delayed engagement can result from pressure loss, particularly in WG-series transmissions. These symptoms often require immediate inspection of the cover and its associated 0636302008 SCREW PLUG to prevent cascading damage.

Technical Specifications

Compatibility

This cover is primarily compatible with ZF’s WG-series powershift transmissions used in construction machinery. It fits the WG180, WG200, and WG210 models, which are common in articulated dump trucks and wheel loaders. The part also applies to select Ergopower and Ecomat variants where the cover interfaces with the 2094298054 HOUSING. Always verify the transmission serial number before ordering, as minor design changes occurred after 2015 production runs.
