ZF 4108.306.091 PIN for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 4108.306.091 PIN is a precision-machined locating and pivot component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part, identified by SKU 4108.306.091, serves as a critical alignment dowel within the shift mechanism and clutch housing assembly. It ensures that adjacent components, such as the 4108101108 HOUSING, remain correctly positioned under high torsional loads. Without this pin, the transmission’s internal geometry can shift, leading to premature wear on the 4108301436 INPUT SHAFT and surrounding fasteners.

Symptoms of Failure

When the 4108.306.091 PIN becomes worn or sheared, operators may notice these specific failure indicators:

• Erratic gear engagement or “gear hunting” – A worn pin allows the shift rail to move out of tolerance, causing the transmission to slip between gears under load.
• Metallic rattling from the bell housing – Loose pin movement creates a distinct tapping noise during idle or deceleration, often misdiagnosed as a bearing issue.
• Oil seepage at the housing joint – A deformed pin can distort the mating surface, compromising the 4108306172 GASKET seal and leading to gradual fluid loss.
• Increased vibration during shifting – The pin’s failure to maintain alignment causes the shift fork to bind, transmitting harsh feedback through the gear lever.

Technical Specifications

Compatibility

This pin is factory-specified for the ZF WG100, WG130, and WG131 off-highway transmissions. It is also used in select WG180 and WG200 variants that share the same shift housing architecture. Always verify the 0730365280 TYPE PLATE on your unit to confirm model revision before ordering.
