ZF 4657.054.164 4 WG 210 Powershift Transmission Assembly | Complete Unit

Overview

This ZF 4657.054.164 4 WG 210 Powershift Transmission Assembly is a complete, ready-to-install unit designed for heavy-duty industrial applications. 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 sealed housing. The SKU 4657.054.164 replaces the original factory assembly and is engineered to restore full power-shift functionality in loaders, dozers, and material handlers. This unit sits directly between the engine flywheel and the final drive, managing torque multiplication and gear ratio changes under load without clutching.

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 when moving from neutral to forward or reverse. This often indicates internal seal degradation within the 4657.054.164 assembly.
• Transmission overheating under light load: A failing unit may cause the transmission fluid to exceed normal operating temperatures quickly, even during low-stress maneuvers. This points to worn bearings or a failing torque converter stator inside the assembly.
• Oil leaks at the housing joints: Pressurized fluid escaping from the mating surfaces between the main case and the HOUS.FRONT SECT or the HOUSING REAR PART signals gasket failure or housing cracks, requiring immediate replacement of the complete unit.
• Loss of power in higher gears: If the machine struggles to maintain speed on inclines or under load, the internal clutches are likely slipping. This symptom is common when the 4657.054.164 assembly has exceeded its service life.

Technical Specifications

Compatibility

This 4657.054.164 assembly is specifically engineered for the ZF WG 210 series powershift transmissions. It is directly compatible with models including the WG180, WG200, and WG210 found in construction and agricultural machinery from manufacturers such as Case, New Holland, and Liebherr. The unit also fits select variants of the 4WG-210 and 4WG-200 systems. For proper installation, ensure the TRANSMISSION HOUSING and the HOUSING REAR SECTION are inspected for wear before mounting this assembly.

Frequently Asked Questions

Q: Can this 4657.054.164 assembly be rebuilt, or is it a sealed unit?
A: This is a complete assembly designed for direct replacement. While internal components like clutch packs are serviceable, the unit is typically replaced as a whole to ensure all seals and bearings are fresh. We recommend pairing it with a new TRANSMISSION HOUSING for optimal fit.

Q: What is the typical lifespan of this WG 210 assembly under heavy use?
A: With proper maintenance and clean fluid, the 4657.054.164 can last 8,000 to 12,000 operating hours. Symptoms like slipping or overheating usually appear near the end of this range, signaling the need for replacement.

Q: Does this unit include the torque converter?
A: Yes, the 4 WG 210 assembly includes an integrated torque converter. For full installation, verify that the HOUS.FRONT SECT is free of cracks to prevent fluid loss.
