ZF 4657.056.180 6 WG 210 Powershift Transmission Assembly | Complete Unit

Overview

The ZF 4657.056.180 6 WG 210 Powershift Transmission Assembly is a complete, factory-grade unit designed for heavy-duty industrial applications. This assembly serves as the central power transfer hub within the WG 210 Series transmission, integrating the clutch packs, planetary gear sets, and hydraulic control systems into a single, ready-to-install package. The SKU 4657.056.180 is a direct replacement for worn or failed assemblies, ensuring minimal downtime for loaders, graders, and material handlers. When rebuilding, this unit must be paired with a structurally sound 4657101082: TRANSMISSION HOUSING to guarantee proper alignment and oil sealing.

Symptoms of Failure

• Erratic gear engagement and slipping under load: When the internal clutch packs wear, the transmission may hesitate or slip during shifting, especially in forward gears.
• Low hydraulic pressure and delayed response: A failing assembly often causes pressure drops, leading to sluggish direction changes or complete loss of drive.
• Metallic grinding noises from the bell housing: Worn bearings or damaged planetary gears produce distinct grinding sounds during operation.
• External oil leaks near the rear seal area: Cracks in the assembly housing or degraded gaskets allow transmission fluid to escape, often visible around the 4657201170: HOUSING REAR PART.

Technical Specifications

Compatibility

This complete assembly is engineered for the ZF WG 210 Series of powershift transmissions. It is directly compatible with the WG180, WG200, and WG210 models commonly found in construction and agricultural machinery. The unit also fits select ZF 6WG-210 variants used in telehandlers and wheel loaders. For proper installation, ensure the 4657201166: HOUS.FRONT SECT and 4657298102: HOUSING REAR SECTION are inspected for wear before mounting this assembly.
