ZF 4460.268.006 GEAR SHIFT FORK for WG200 | OEM Genuine Part

Overview

The ZF 4460.268.006 GEAR SHIFT FORK is a precision-engineered internal selector component specifically designed for the WG 200 series heavy-duty transmission. This OEM genuine part, identified by SKU 4460.268.006, is responsible for engaging and disengaging the synchronizer sleeves to facilitate smooth gear changes. Mounted directly on the shift rail within the transmission housing, this fork translates the lateral motion of the shift mechanism into axial movement of the sliding gear. When functioning correctly, it ensures positive gear engagement and eliminates driveline hesitation during load shifts.

Symptoms of Failure

• Hard shifting or gear clash: A worn shift fork pad or bent fork arm prevents the synchronizer from aligning correctly, causing grinding noises when attempting to engage a gear.
• Transmission jumping out of gear: If the fork tines are worn or the internal detent is damaged, the transmission may unexpectedly pop out of gear under load, particularly in 2nd or 3rd gear.
• Sluggish or incomplete gear engagement: Operators may notice a delay or a “notchiness” when moving the shifter, indicating the fork is no longer applying sufficient pressure to the synchronizer sleeve.
• Unusual metallic rattling from the gearbox: Excessive play in the shift fork pivot point can create a loose rattle that is audible at idle or during deceleration.

Technical Specifications

Compatibility

This shift fork is engineered for the ZF WG 200 series transmission family. It is a direct fit for the WG180, WG200, and WG210 models used in medium-duty trucks, buses, and off-highway equipment. The 4460.268.006 fork is also compatible with certain early-build WG150 variants that utilize the same shift rail spacing. Always verify the shift rail diameter and fork pad thickness against your existing assembly before installation.

Installation Notes

When replacing the 4460.268.006 gear shift fork, it is critical to inspect the shift rail and synchronizer hub for scoring. The fork is secured using a 0636011429: HEXAGON SCREW and a 0730100365: WASHER to ensure proper clamping force. The shift mechanism also relies on the 4460165051: CONSOLE and the 4460368311: CONSOLE to provide stable mounting points for the shift cables. Torque the hexagon screw to 45 Nm using a thread-locking compound to prevent loosening under vibration.
