Overview
The ZF 0631.302.084 CYLINDRICAL PIN is a precision-engineered locating and alignment component designed for the WG100, WG130, and WG131 transmission series. This OEM genuine part ensures accurate positioning of internal assemblies, maintaining critical clearances within the gear train. As a fastener classified under Springs & Fasteners, the SKU 0631.302.084 serves as a dowel pin that secures mating components against shear forces and vibration. It is commonly installed adjacent to the 2098117002: HOUSING and the 2098301052: REAR AXLE HOUS., where precise alignment is non-negotiable for long-term durability.
Symptoms of Failure
- Transmission housing misalignment and vibration: A worn or sheared cylindrical pin allows the housing to shift, causing abnormal gear noise and harsh shifting during acceleration.
- Oil seepage at housing joints: When the pin fails to maintain proper alignment, the seal between the 2098117002: HOUSING and the 2098301052: REAR AXLE HOUS. can break, leading to slow oil leaks around the mating surfaces.
- Loose fasteners and stud breakage: A compromised pin places excessive stress on adjacent hardware. You may notice the 0636103300: STUD or the 0637101164: HEXAGON NUT loosening repeatedly, even after retorquing.
- Gear slipping under load: Misalignment from a failed pin can cause partial disengagement of gear sets, resulting in intermittent power loss during heavy-duty operation.

Compatibility
This cylindrical pin is engineered for the ZF WG100, WG130, and WG131 powershift transmission families. It is also suitable for the WG180 and WG200 series when used in identical alignment applications. The pin interfaces directly with the 2098117002: HOUSING and the 2098301052: REAR AXLE HOUS., and it works in concert with the 0636103300: STUD and 0637101164: HEXAGON NUT to secure the assembly. Always verify your transmission model and housing configuration before ordering.
