ZF 4657.054.141 4 WG 210 Powershift Transmission Assembly | Complete Unit

Overview

This ZF 4657.054.141 4 WG 210 Powershift Transmission Assembly is a complete unit engineered for heavy-duty industrial and agricultural machinery. As the core hydraulic-mechanical assembly in the WG 210 series, it integrates the torque converter, planetary gear sets, and clutch packs into a single, ready-to-install package. The SKU 4657.054.141 replaces worn or failed assemblies, restoring full power transfer and shift control in ZF powershift transmissions. It sits at the center of the driveline, directly coupling the engine output to the final drive components.

Symptoms of Failure

• Delayed or harsh gear engagement: When the internal clutch packs or valve body wear, operators experience a noticeable lag or jarring shift between forward and reverse gears.
• Transmission fluid contamination: Debris from worn friction plates or seals circulates through the system, causing erratic pressure and overheating.
• Loss of power under load: A failing assembly allows internal slippage, reducing torque delivery to the wheels during heavy pulling or grading operations.
• External oil seepage at housing joints: Cracks or gasket failures in the assembly body lead to fluid loss, often visible around the bell housing or rear section.

Technical Specifications

Compatibility

This complete assembly is designed for the ZF WG 210 series powershift transmissions. It is directly compatible with models including the WG 180, WG 200, and WG 210. The unit also fits select variants of the WG 150 and WG 160 series when used with the appropriate 4657101078: TRANSMISSION HOUSING. For proper installation, ensure the 4657201166: HOUS.FRONT SECT and 4657201168: HOUSING REAR PART are inspected for wear. In some configurations, the 4657298101: HOUSING REAR SECTION is also required for complete sealing.

Frequently Asked Questions

Q: Can this assembly be rebuilt, or is it a sealed unit?
A: The ZF 4657.054.141 is a complete unit that can be disassembled for internal inspection. However, due to the complexity of the clutch pack clearances and valve body calibration, replacement with a new assembly is often more cost-effective than rebuilding.

Q: What is the typical lifespan of this transmission assembly under normal operating conditions?
A: In agricultural or construction applications with proper maintenance, the assembly typically lasts 8,000 to 12,000 hours. Frequent fluid and filter changes using ZF-approved oil significantly extend service life.

Q: Does this part include the torque converter?
A: Yes, the complete unit includes the integrated torque converter and all internal planetary gear sets. It is ready for installation once the HOUS.FRONT SECT and rear housing components are attached.
