ZF 4657.054.028 4 WG 210 Powershift Transmission Assembly | Complete Unit

Overview

This ZF 4657.054.028 4 WG 210 Powershift Transmission Assembly is a complete, ready-to-install unit designed for heavy-duty industrial and agricultural machinery. As the core drivetrain component in the WG 210 series, this assembly manages torque distribution across multiple gear ranges, enabling smooth, clutchless shifting under full load. The SKU 4657.054.028 integrates the main gear cluster, hydraulic valve body, and output shaft within a sealed housing, ensuring reliable power transfer in loaders, graders, and material handlers. When rebuilding your transmission, this complete unit replaces the worn internal assembly while interfacing directly with the TRANSMISSION HOUSING and the HOUS.FRONT SECT to restore factory performance.

Symptoms of Failure

• Erratic gear engagement under load: When the internal clutch packs or planetary gears wear, operators experience delayed or harsh shifting, especially when transitioning between forward and reverse. This “ZF transmission slipping under load” symptom often requires immediate replacement of the complete assembly.
• Hydraulic oil contamination from metal debris: Worn bearings or gear teeth shed metallic particles into the transmission fluid. If you notice “shiny particles in transmission oil” during routine checks, the 4657.054.028 unit may be shedding internal components.
• Persistent oil leaks at the housing seam: Cracks or fatigue in the assembly body allow ATF to escape. This “ZF WG210 oil leak at bell housing” issue often originates from the mating surface with the HOUSING REAR PART.
• Unusual whining or grinding noises: A high-pitched whine during acceleration or a grinding sound in neutral indicates worn bearings or damaged gear teeth within the assembly.

Technical Specifications

Compatibility

This complete assembly is engineered for the ZF WG 210 series, but it also fits select variants in the WG180 and WG200 families due to shared bolt patterns and shaft dimensions. Specifically, it is compatible with ZF 4 WG 210, 4 WG 200, and 4 WG 180 transmissions found in Case, New Holland, and Liebherr equipment. The unit requires a matching CYLINDRICAL PIN for precise alignment during installation. Always verify your transmission serial number before ordering.

Frequently Asked Questions

Q: Can I install this 4657.054.028 assembly without replacing the housing?
A: Yes, provided the existing TRANSMISSION HOUSING is free of cracks or warping. However, we recommend replacing the CYLINDRICAL PIN and all seals during the swap.

Q: What is the typical lifespan of this complete unit?
A: Under normal operating conditions with proper maintenance, the 4 WG 210 assembly lasts 8,000–12,000 hours. Harsh environments or neglected oil changes can reduce this to 5,000 hours.

Q: Does this part include the valve body and solenoids?
A: Yes, the 4657.054.028 ships as a fully assembled unit with the hydraulic control module, clutch packs, and planetary gears pre-installed. You only need to attach the HOUS.FRONT SECT and HOUSING REAR PART.
