Overview
The ZF 4616.302.007 COVER is a critical sealing component engineered specifically for the WG 65 series transmission. This OEM genuine part encloses the rear section of the gearbox housing, protecting internal components from contaminants while maintaining proper oil pressure. Positioned at the output flange area, the cover integrates with the TRANSMISSION HOUSING to form a leak-proof barrier. The SKU 4616.302.007 is manufactured to ZF’s original tolerances, ensuring a precise fit that aftermarket alternatives often fail to replicate.
Symptoms of Failure
- Oil seepage around the rear flange: A worn or cracked 4616.302.007 cover often causes transmission fluid to accumulate near the output shaft, leading to visible drips after parking.
- Contaminated transmission fluid: When the cover loses its seal, dirt and moisture enter the system, causing the oil to appear milky or gritty during inspection.
- Abnormal gear engagement noise: A compromised cover allows internal pressure fluctuations, resulting in delayed or harsh shifting, particularly in WG 65 units under load.
- Reduced hydraulic pressure: Cracks in the cover disrupt the oil circuit, triggering warning codes related to low line pressure in electronic-controlled models.

Compatibility
This cover is primarily designed for the ZF WG 65 series, but it also fits select models in the WG180 and WG200 families due to shared housing architecture. Verified compatible transmissions include WG 65-1, WG 65-2, WG 180-3, and WG 200-4. Always cross-reference the HEXAGON SCREW (0636011038) and HEXAGON SCREW (0636011118) for proper mounting. For heavy-duty applications, the HEXAGON SCREW (0636016015) provides additional clamping force.
