Overview
The ZF 4616.301.269 COVER is a precision-engineered sealing component designed for the WG 65 series transmission. This OEM genuine part serves as the primary closure for the transmission housing, securing internal lubricants and protecting gear assemblies from external contaminants. Positioned on the rear or side access port of the WG 65 gearbox, this cover works in conjunction with the TRANSMISSION HOUSING to maintain structural integrity under high-torque conditions. The SKU 4616.301.269 ensures exact fitment and material compatibility for ZF’s heavy-duty industrial transmissions.
Symptoms of Failure
- Oil seepage around the cover perimeter: When the gasket surface degrades, transmission fluid escapes, leaving visible wet spots on the housing exterior.
- Gear engagement hesitation: A compromised cover allows pressure loss, leading to delayed shifting or slipping under load.
- Metallic debris in the oil pan: Cracks in the cover can allow foreign particles to enter the lubrication system, accelerating internal wear.
- Vibration at the mounting points: Loose or warped covers cause abnormal resonance, often accompanied by rattling during operation.

Compatibility
This cover is engineered for the WG 65 transmission series, but its mounting pattern and sealing profile also fit select models in the WG180, WG200, and WG250 families. It is commonly paired with HEXAGON SCREW fasteners (M10 x 30mm) for secure attachment. For installations requiring additional sealing, the HEXAGON SCREW (M12 x 35mm) and HEXAGON SCREW (M8 x 25mm) are also used in adjacent housing ports. Always verify compatibility with your transmission’s serial number before ordering.
