ZF 0731.208.220 LOCKING PIN for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0731.208.220 LOCKING PIN is a precision-engineered fastener designed to secure critical shift rail and selector fork assemblies within ZF WG100, WG130, and WG131 transmissions. This OEM genuine part prevents axial movement of mating components, ensuring precise gear engagement and drivetrain stability. The SKU 0731.208.220 is manufactured to ZF’s original tolerances, providing a direct replacement for worn or damaged pins that compromise transmission integrity. When installed alongside the 5838109007 DIFFERENTIAL assembly, this locking pin maintains proper alignment under high-torque conditions.

Symptoms of Failure

• Transmission gear slipping under load: A worn 0731.208.220 locking pin allows shift forks to drift, causing intermittent gear disengagement during acceleration or hill climbing.
• Unusual metallic rattling from the transmission housing: Loose locking pins create play between the selector shaft and fork, producing a distinct chatter at idle or low RPM.
• Difficulty engaging or disengaging gears: Excessive pin wear prevents the shift rail from locking into position, resulting in a vague or incomplete shift feel.
• Oil contamination from metal debris: A fractured locking pin sheds particles into the transmission fluid, often detected during routine oil changes or when inspecting the 0750117075 TAPER ROLLER BEARING assembly.

Technical Specifications

Compatibility

This locking pin is engineered for ZF WG-series transmissions, specifically the WG100, WG130, and WG131 models. It is also compatible with select variants of the WG180 and WG200 series where the shift rail diameter matches 8.0 mm. For differential-related applications, pair this pin with the 2095209019 DIFFERENTIAL unit to ensure proper locking of the output shaft assembly. Always verify the shift fork bore condition before installation, as worn bores may require the 0631329086 SPRING PIN for additional retention.
