ZF 6006.022.105 FS SG 6 S for WG210 | OEM Genuine Part

Overview

The ZF 6006.022.105 FS SG 6 S for WG210 is a precision-engineered synchronizer assembly designed for the WG 210 Series of heavy-duty powershift transmissions. This OEM genuine part, identified by SKU 6006.022.105, sits within the main shaft cluster and is responsible for enabling smooth gear engagement between the forward and reverse clutch packs. It acts as a critical interface between the HOUS.FRONT SECT and the output shaft, ensuring that torque is transferred without hesitation during shifting operations. Without this component, the transmission cannot achieve the precise timing required for industrial applications like construction loaders or mining trucks.

Symptoms of Failure

When the ZF 6006.022.105 synchronizer wears out, operators often notice hard shifting between gears accompanied by a grinding noise, especially when transitioning from forward to reverse. Another common failure symptom is intermittent gear slipping under load, where the transmission momentarily loses drive power on inclines. You may also detect metal particles in the transmission fluid during routine oil changes, indicating that the synchronizer hub has begun to fracture. Finally, delayed engagement when selecting a gear—a lag of 2-3 seconds—points directly to this part losing its frictional grip. These issues often arise when the TRANSMISSION HOUSING experiences vibration, accelerating wear on the synchronizer assembly.

Technical Specifications

Compatibility

This synchronizer is specifically engineered for the ZF WG 210 Series transmissions, which are commonly found in off-highway vehicles. It is also compatible with the WG 180 and WG 200 models when used in conjunction with the correct HOUSING REAR PART. Additionally, it fits select WG 160 variants that share the same shaft spline count (24 splines). For proper installation, ensure the CYLINDRICAL PIN is aligned correctly to prevent axial play. Always verify your transmission’s serial number against the WG210 series parts list before ordering.
