Overview
The ZF 4616.306.058 COVER is a precision-engineered sealing component designed specifically for the WG 65 series transmission. This OEM genuine part sits on the rear section of the transmission housing, providing a critical barrier that protects internal gear assemblies and hydraulic components from contaminants while retaining transmission fluid under high pressure. As an integral element of the drivetrain assembly, the SKU 4616.306.058 works in conjunction with the 4616105415 OUTPUT and the 4616101094 TRANSMISSION HOUSING to ensure optimal torque transfer and system integrity. Manufactured to ZF’s exacting standards, this cover is essential for maintaining the durability and performance of heavy-duty industrial transmissions.
Symptoms of Failure
When the ZF 4616.306.058 COVER begins to degrade, operators may notice several distinct warning signs. Oil leaks around the rear transmission seal are the most common indicator, often appearing as drips or wet spots beneath the vehicle. Gear engagement hesitation or slipping can occur as fluid pressure drops due to cover deformation. Contaminated transmission fluid from debris ingress is another symptom, leading to accelerated wear of internal components. Finally, unusual whining or grinding noises from the transmission housing may signal that the cover has loosened or cracked, compromising the assembly’s structural stability.

Compatibility
This cover is engineered for the ZF WG 65 series, but its design also makes it compatible with several other ZF transmission models that share similar rear housing configurations. It fits the WG 180, WG 200, and WG 210 series transmissions commonly found in off-highway vehicles, construction equipment, and agricultural machinery. For proper installation, ensure the 4616303144 OUTPUT FLANGE is correctly aligned, and use the 0636011038 HEXAGON SCREW for secure fastening. Always verify compatibility with your specific transmission serial number before ordering.
