ZF 0636.101.512 CAP SCREW for WG200 | OEM Genuine Part

Overview

The ZF 0636.101.512 CAP SCREW is a critical fastening component engineered specifically for the WG 200 Series transmission. This OEM genuine part secures the TRANSMISSION HOUSING assembly, ensuring that internal components remain precisely aligned under high-torque loads. Without this cap screw, the structural integrity of the gearbox is compromised. The SKU 0636.101.512 is manufactured to ZF’s exacting tolerances, providing a leak-proof seal and preventing axial movement of the OUTPUT FLANGE during operation.

Symptoms of Failure

• Transmission fluid seepage around the housing joint: A worn or stripped 0636.101.512 cap screw can cause oil to weep from the mating surface, leading to low fluid levels and eventual gear slipping.
• Abnormal vibration or driveline noise: When this fastener loosens, the DISCONNECTION mechanism may shift, producing a distinct clattering sound during gear changes.
• Intermittent loss of hydraulic pressure: A failing cap screw allows the housing to flex, disrupting the seal around the valve block and causing erratic shift patterns.
• Visible corrosion or thread galling: Over time, exposure to heat and oil can degrade the cap screw’s coating, making removal difficult and risking damage to the HEXAGON SCREW threads.

Technical Specifications

Compatibility

This cap screw is primarily designed for the ZF WG 200 Series, including the WG180, WG200, and WG210 variants. It is also used in certain WG 150 models where the TRANSMISSION HOUSING shares the same bolt pattern. Always verify fitment by cross-referencing the SKU 0636.101.512 with your transmission’s serial number. The fastener is not compatible with older ZF 4HP or 5HP series without adapter kits.
