ZF 5838.300.113 COVER | OEM Genuine Part

Overview

The ZF 5838.300.113 COVER is a critical OEM genuine component designed to seal and protect the internal mechanisms of heavy-duty construction machinery transmissions. Positioned on the differential housing assembly, this cover prevents contaminants from entering the gear train while maintaining proper lubrication pressure. The SKU 5838.300.113 is precision-engineered to withstand extreme operational loads and thermal cycling common in earthmoving equipment. When paired with a 5838109006 DIFFERENTIAL, this cover ensures the entire drivetrain assembly remains sealed against debris and moisture ingress, directly contributing to transmission longevity.

Symptoms of Failure

• Hydraulic oil seepage around the transmission housing – A worn 5838.300.113 cover gasket surface often causes slow drips, leading to low fluid levels and eventual gear slippage under load.
• Contaminated transmission fluid – Cracks in the cover allow dirt and water to mix with the oil, producing a milky appearance and reducing lubricity in the 0750117075 TAPER ROLLER BEARING assembly.
• Unusual whining or grinding noises from the differential area – Structural fatigue in the cover can misalign the 2095209037 DIFFERENTIAL, causing metal-on-metal contact during operation.
• Vibration during gear engagement – A loose or warped cover destabilizes the 2095309059 DIFF.HOUSING, resulting in inconsistent torque transfer and harsh shifting.

Technical Specifications

Compatibility

This cover is engineered for ZF WG series powershift transmissions commonly installed in wheel loaders, graders, and excavators. Verified compatible models include the WG180, WG200, WG210, and WG310 series. It also fits select ZF Ergopower and Ecolite transmissions used in agricultural tractors. Always verify the bolt pattern and gasket profile against your existing 2095309059 DIFF.HOUSING before installation.
