ZF 4657.056.060 6 WG 210 Powershift Transmission Assembly | Complete Unit

Overview

The ZF 4657.056.060 6 WG 210 Powershift Transmission Assembly is a complete, factory-matched unit designed for heavy-duty off-highway applications. This assembly integrates the full gear train, clutch packs, and hydraulic control system within a single, ready-to-install package. As the core power transfer module in the WG 210 series, it replaces worn or failed assemblies to restore original machine performance. The SKU 4657.056.060 is a direct OEM-grade replacement, ensuring precise fitment and reliable operation under high torque loads. This unit sits centrally in the driveline, connecting the engine output to the final drive, and is commonly paired with the TRANSMISSION HOUSING for structural integrity.

Symptoms of Failure

• Erratic gear engagement or slipping under load: Worn clutch discs or hydraulic valve degradation cause delayed or incomplete shifts, especially when moving heavy loads.
• External oil leaks at housing joints: Cracks or gasket failure in the HOUS.FRONT SECT or HOUSING REAR PART lead to fluid loss and pressure drops.
• Unusual whining or grinding noises: Bearing wear or gear tooth damage within the assembly produces metallic sounds during operation.
• Overheating transmission fluid: Internal friction from failing components generates excessive heat, often accompanied by burnt oil smell.

Technical Specifications

Compatibility

This complete assembly is engineered for the ZF WG 210 series transmissions. It is also compatible with earlier WG 180 and WG 200 models when used with the correct adapter kit. The unit directly replaces part numbers 4657.056.050 and 4657.056.070 in the same series. For proper installation, verify that the TRANSMISSION HOUSING and HOUS.FRONT SECT are free from cracks. The HOUSING REAR PART must also match the assembly’s bolt pattern. Always replace the CYLINDRICAL PIN during reinstallation to ensure alignment.
