ZF 2095.306.099 GEAR SHIFT FORK for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 2095.306.099 GEAR SHIFT FORK is a precision-machined actuation component engineered for the WG100, WG130, and WG131 heavy-duty transmission series. This OEM genuine part directly engages the sliding sleeves on the mainshaft, translating driver input into precise gear selection. Positioned within the shift rail assembly, the fork ensures positive engagement and disengagement of gear sets. The SKU 2095.306.099 is a direct replacement for the original factory component, maintaining the exact metallurgical and dimensional tolerances required for synchronized shifting under high torque loads. When paired with a properly functioning 0750117075: TAPER ROLLER BEARING, the shift fork reduces axial play and ensures consistent fork-to-sleeve alignment.

Symptoms of Failure

• Hard shifting or gear clash: A worn fork pad or bent fork arm prevents the sliding sleeve from fully engaging the gear hub, causing grinding noises during upshifts or downshifts.
• Unexplained gear disengagement (pop-out): When the fork’s contact surfaces wear beyond 0.5mm, the detent spring cannot hold the sleeve in position, leading to the transmission jumping out of gear under load.
• Metallic debris in transmission oil: Abrasion of the fork’s hardened steel pads generates fine metallic particles that contaminate the lubricant, often accompanied by a visible “glitter” during oil changes.
• Sluggish or incomplete shift travel: A cracked or deformed fork body restricts the shift rail movement, resulting in a “notchy” feel or the inability to select specific gears.

Technical Specifications

Compatibility

This shift fork is specifically designed for ZF’s WG-series manual transmissions with synchronized reverse. Verified direct fitment includes the WG100, WG130, and WG131 models. It may also be compatible with the WG180 and WG200 variants when used in the 3rd/4th gear shift rail position, though cross-referencing the shift rail diameter is recommended. The fork interfaces directly with the 0631329086: SPRING PIN that secures it to the shift rail, and works in concert with the 5838109007: DIFFERENTIAL assembly in the output section to manage torque distribution during gear changes. For complete rebuilds, pairing this fork with a new 2095209019: DIFFERENTIAL ensures matched wear patterns across the drivetrain.
