Overview
The ZF 4616.305.063 GEAR SHIFT FORK is a precision-machined component engineered specifically for the WG65 transmission series. This OEM genuine part actuates the sliding sleeve within the gear cluster, enabling smooth engagement and disengagement of gears during operation. Positioned on the shift rail assembly inside the TRANSMISSION HOUSING, the fork transfers linear motion from the shift mechanism to the synchronizer hub. The SKU 4616.305.063 is manufactured to ZF’s original tolerances, ensuring exact fitment and reliable load distribution across the fork’s contact pads.
Symptoms of Failure
- Gear grinding or hard shifting: A worn shift fork fails to fully engage the synchronizer, causing audible grinding when moving into gear.
- Unexpected gear disengagement: If the fork’s fork pads are worn, the transmission may slip out of gear under load, especially in higher ranges.
- Excessive shift lever play: Loose or bent forks create slop in the shift linkage, making it difficult to find gears precisely.
- Metallic debris in transmission oil: Worn fork pads shed material into the sump, often visible during oil changes as fine metallic particles.

Compatibility
This shift fork is designed for the ZF WG65 transmission series, which includes models such as WG65, WG80, WG100, WG120, WG150, WG180, and WG200. It is also compatible with select ZF Ecomat and Ecolife variants that share the same shift rail spacing and fork geometry. Always verify the shift fork’s orientation and rail diameter against your specific transmission’s service manual before installation.
Installation Notes
When replacing the shift fork, inspect the shift rail and synchronizer assembly for wear. Secure the fork using the correct HEXAGON SCREW (M8 x 20) and HEXAGON SCREW (M10 x 25) for the rail clamps. The HEXAGON SCREW (M12 x 30) secures the fork pivot bracket. Torque all fasteners to ZF specifications to prevent loosening during operation.
