Overview
The ZF 4616.301.045 COVER is a critical OEM genuine component engineered specifically for the WG 65 series transmission. This part serves as the protective and sealing interface on the transmission housing, preventing contamination ingress and maintaining internal oil pressure. Positioned on the main casing, the cover integrates directly with the TRANSMISSION HOUSING to form a sealed enclosure for the gear train and hydraulic control unit. The SKU 4616.301.045 is manufactured to ZF’s exacting tolerances, ensuring a precise fit and long service life in heavy-duty industrial applications.
Symptoms of Failure
- External oil seepage around the cover perimeter: A worn or cracked 4616.301.045 cover often leads to visible fluid leaks, especially under high operating temperatures or pressure spikes.
- Contaminated transmission fluid: When the cover loses its seal, dirt and moisture enter the system, causing premature wear on internal components and degraded hydraulic performance.
- Unusual gear engagement noise: A compromised cover can allow slight misalignment of the housing, resulting in increased vibration or grinding sounds during shifting.
- Reduced hydraulic pressure: Leaks at the cover interface directly lower system pressure, leading to sluggish clutch engagement or gear slipping under load.

Compatibility
This cover is designed for the ZF WG 65 series transmission family. Based on its form factor and mounting pattern, it is also compatible with the following ZF models: WG 80, WG 120, WG 180, and WG 200. Always verify the specific housing configuration before installation, as the HEXAGON SCREW (M8x25) and HEXAGON SCREW (M10x30) are required for secure mounting. For additional fastening points, the HEXAGON SCREW (M12x40) is used in higher-torque applications.
