Overview
The ZF 4657.054.075 4 WG 210 Powershift Transmission Assembly is a complete, factory-matched unit designed for heavy-duty off-highway applications. This assembly integrates the core gear train, clutch packs, and hydraulic control components into a single, ready-to-install package. As a complete unit, it eliminates the need for piecemeal rebuilding, reducing downtime for equipment in construction, mining, and agricultural sectors. The SKU 4657.054.075 specifically identifies this as a fully assembled WG 210 series transmission, ensuring direct compatibility with original ZF mounting points and driveline connections. It sits at the heart of the powertrain, transferring engine torque through four forward and reverse speeds via a modulated powershift system.
Symptoms of Failure
- Delayed or harsh engagement: When the internal clutch packs or valve body wear, operators notice a significant lag between shifting and actual gear engagement, often accompanied by a jarring thud. This indicates hydraulic pressure loss within the assembly.
- Transmission overheating under load: A failing complete unit often exhibits rapid temperature spikes during normal operation. This is typically caused by internal wear debris clogging the oil feed passages or a failing torque converter stator.
- Intermittent gear slippage in forward ranges: The transmission may suddenly lose power delivery in specific gears, particularly under heavy load or on inclines. This points to worn friction discs or damaged sealing rings inside the 4657.054.075 assembly.
- External oil seepage from bell housing: Leaks originating from the joint between the transmission and engine adapter are a common failure mode. This often stems from a compromised front seal or a cracked TRANSMISSION HOUSING.

Compatibility
This complete unit is engineered specifically for the ZF WG 210 Series transmission family. It is a direct replacement for models including the WG180, WG200, and WG210 variants found in loaders, graders, and telescopic handlers. The assembly is designed to interface with the HOUS.FRONT SECT and the HOUSING REAR PART without modification. For secure mounting, the assembly utilizes a CYLINDRICAL PIN for precise alignment during installation. It is not backward compatible with the older WG 120 series without significant adapter plate changes.

Frequently Asked Questions
Q: Does the 4657.054.075 include the torque converter?
A: No. This complete unit includes the gear train, clutch packs, and valve body, but it is supplied without the torque converter. You must order the converter separately based on your engine flywheel housing pattern.
Q: Can I install this unit without removing the cab on my loader?
A: Yes, in most cases. The WG 210 assembly is designed for service access through the belly pan. However, you will need to support the unit with a transmission jack and disconnect the driveline at the output flange before removal.
Q: What is the warranty on this complete assembly?
A: This unit carries a standard 12-month warranty against manufacturing defects. It is tested on a dynamometer before shipment to verify shift quality and pressure specifications.
