ZF 0636.101.054 CAP SCREW for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0636.101.054 CAP SCREW is a critical OEM genuine fastener engineered for the WG100, WG130, and WG131 transmission series. This cap screw secures internal housing assemblies, ensuring precise clamping force to prevent fluid migration and component shift under high torque loads. As part of the Springs & Fasteners category, SKU 0636.101.054 is installed directly into the main transmission housing, often paired with the 2094101012: TRANSMISSION HOUSING to maintain structural integrity. Without this cap screw, the entire gear train alignment can be compromised, leading to accelerated wear on adjacent components.

Symptoms of Failure

• Transmission fluid seepage around bolt heads: A loose or fatigued cap screw allows oil to bypass the sealing interface, often visible as wet spots near the housing joint.
• Abnormal gear rattle or vibration: When the cap screw loses preload, the 2094301036: HOUSING can shift slightly, creating audible chatter during load changes.
• Intermittent gear slipping under load: Insufficient clamping force permits internal shafts to micro-move, disrupting clutch pack engagement and causing hesitation.
• Metal debris in transmission fluid: A fractured cap screw sheds particles that circulate through the system, damaging bearings and the 2094298057: HOUSING bore surfaces.

Technical Specifications

Compatibility

This cap screw is directly compatible with ZF WG100, WG130, and WG131 transmissions. It is also used in select WG180 and WG200 models where the same housing bolt pattern applies. Always verify thread pitch and length against your specific housing, particularly when replacing the 2094301071: COVER assembly, as cover thickness variations may require a different screw length.
