Overview
This complete ZF 4657.054.172 4 WG 210 Powershift Transmission Assembly is a fully integrated unit designed for heavy-duty industrial and agricultural machinery. As a core component of the WG 210 series, this assembly manages torque distribution and gear engagement across four forward speeds. The SKU 4657.054.172 replaces worn or failed assemblies to restore driveline efficiency. It sits between the engine output and the final drive, integrating the TRANSMISSION HOUSING which protects internal gears and clutches from debris and stress.
Symptoms of Failure
- Oil leaks near the bell housing: When the assembly wears, seals degrade, causing visible fluid drips under the vehicle, especially after prolonged operation.
- Gear slipping under load: Worn clutches or damaged shafts within the unit cause intermittent power loss, particularly when shifting from second to third gear.
- Delayed engagement or harsh shifting: A failing assembly often produces grinding noises or a noticeable lag when moving from neutral into drive or reverse.
- Overheating transmission fluid: Internal friction from worn components raises operating temperatures, triggering warning lights or burnt fluid odor.

Compatibility
This complete assembly is engineered for the ZF WG 210 series. It is also compatible with WG 180 and WG 200 models when used as a direct replacement for the main transmission housing assembly. The unit integrates with the HOUS.FRONT SECT and the HOUSING REAR PART to form the complete casing. For extended rebuilds, the HOUSING REAR SECTION is also required to seal the rear output shaft. Common applications include ZF 4WG-210, 4WG-200, and 4WG-180 transmissions found in loaders, graders, and material handlers.

Frequently Asked Questions
Q: Can this assembly be installed without replacing the housing sections?
A: Yes, but we recommend inspecting the TRANSMISSION HOUSING and HOUS.FRONT SECT for cracks or warping before reuse, as worn housings can cause premature failure of the new assembly.
Q: What is the typical lifespan of the 4657.054.172 unit?
A: With proper maintenance and clean fluid, this assembly can last 8,000–12,000 operating hours. Failure often begins with seal degradation around the HOUSING REAR PART.
Q: Does this part include the screen sheets and cap screws?
A: No, this is a bare assembly. You will need to order the SCREEN SHEET (fine) and CAP SCREW sets separately for a complete rebuild.
