ZF 2094.342.009 GEAR SHIFT FORK for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2094.342.009 GEAR SHIFT FORK is a critical actuation component within the WG100, WG130, and WG131 transmission assemblies. This genuine OEM part, identified by SKU 2094.342.009, is responsible for engaging and disengaging the synchronizer sleeves to select specific gear ratios. Positioned along the shift rail system inside the main transmission casing, this fork translates lateral movement from the shift mechanism into precise axial motion, ensuring smooth and reliable gear changes under heavy-duty industrial loads.

Symptoms of Failure

• Hard shifting or gear grinding: A worn shift fork pad or bent fork arm prevents full engagement, causing audible grinding during gear selection.
• Unexplained gear slippage: When the fork fails to hold the synchronizer in position, the transmission may pop out of gear under load, especially in lower ratios.
• Increased shift lever play: Excessive clearance between the fork and the shift collar results in a loose, imprecise feel at the shifter, often accompanied by rattling noises.
• Oil contamination from metal debris: As the fork wears, fine metallic particles enter the lubricant, accelerating damage to the TRANSMISSION HOUSING and internal bearings.

Technical Specifications

Compatibility

This genuine ZF shift fork is specifically engineered for the WG100, WG130, and WG131 series transmissions. While these are the primary applications, the fork may also be compatible with select WG180 and WG200 variants that share the same shift rail spacing and fork pad geometry. Always verify the shift fork thickness and rail slot dimensions against your existing component before installation. The fork operates in conjunction with the HOUSING and HOUSING assemblies that contain the shift mechanism.
