Overview
This ZF 4657.054.073 4 WG 210 Powershift Transmission Assembly is a complete, ready-to-install unit designed for heavy-duty industrial applications. As the core power transfer module in the WG 210 Series, this assembly integrates the main gear cluster, clutch packs, and hydraulic control circuits to deliver seamless shifting under load. The SKU 4657.054.073 replaces worn or failed original assemblies, restoring full torque capacity and operational reliability in wheel loaders, dozers, and material handlers. It sits centrally within the driveline, connecting directly to the TRANSMISSION HOUSING which encloses the rotating components.
Symptoms of Failure
- Delayed or harsh gear engagement: When the assembly wears, internal clutch clearance increases, causing a noticeable lag or jarring shift when moving from neutral to forward or reverse.
- Transmission fluid overheating: Slipping clutches generate excessive heat, often indicated by a rising temperature gauge or burnt oil smell from the breather.
- Intermittent power loss under load: The unit may momentarily lose drive torque when climbing grades or pushing heavy material, signaling worn friction discs or piston seal failure.
- External oil seepage at mating flanges: Deteriorated gaskets between the assembly and the HOUS.FRONT SECT or HOUSING REAR PART can produce visible drips, especially after cold starts.

Compatibility
This complete unit is engineered for the ZF WG 210 transmission series. It is also compatible with select models in the WG 180 and WG 200 families where the bellhousing pattern and input shaft spline match. Common applications include ZF 4 WG 210, 4 WG 200, and 4 WG 180 powershift units found in construction equipment from manufacturers such as Case, New Holland, and Liebherr. Always verify the CYLINDRICAL PIN alignment before final installation.

Frequently Asked Questions
Q: Can this assembly be installed without removing the transmission from the vehicle?
A: No. The ZF 4657.054.073 is a complete unit requiring full transmission removal. We recommend replacing the HOUS.FRONT SECT gasket and all CAP SCREW fasteners during installation.
Q: What is the typical service life of this assembly in a wheel loader?
A: Under normal operating conditions with proper oil maintenance, the unit lasts 8,000–10,000 hours. Early failure often results from contaminated oil bypassing the SCREEN SHEET filters.
Q: Does this part include the valve body and torque converter?
A: No. This assembly includes the main gear housing, clutches, and shafts only. The torque converter and valve body must be ordered separately if needed.
