Overview
The ZF 0631.306.165 CYLINDRICAL PIN is a precision-machined locating component engineered for the WG200 and WG92 series transmissions. This OEM genuine part functions as a critical alignment dowel within the transmission housing assembly, ensuring exact positioning of internal components such as the range selector and peripherals. The SKU 0631.306.165 is manufactured to ZF’s original tolerances, preventing axial movement and maintaining gear mesh accuracy under high-torque conditions. When installed alongside the 4660198001: PERIPHERALS, this pin stabilizes the entire subassembly against vibration-induced wear.
Symptoms of Failure
- Transmission housing misalignment: A worn or sheared 0631.306.165 pin causes the 4660101011: TRANSMISSION HOUSING to shift, leading to uneven gear contact patterns and premature tooth wear.
- Range selector binding: When this cylindrical pin degrades, the 0501209818: RANGE SELECTOR may stick or fail to engage properly, resulting in delayed shift response.
- Oil seepage at housing joints: A loose pin compromises the seal between the 4660301018: HOUSING sections, allowing ATF to weep past gaskets and O-rings.
- Metallic rattling during acceleration: Excessive pin clearance permits internal components to vibrate, creating a distinct knocking sound under load.

Compatibility
This cylindrical pin is specifically designed for ZF WG200 and WG92 series transmissions, including the WG180 variant. It serves as a locating dowel for the 4660101011: TRANSMISSION HOUSING and the 4660301018: HOUSING subassemblies. The 0631.306.165 is also used in certain WG180 applications where the range selector and peripherals require precise alignment. Always verify your transmission serial number before ordering.
