ZF 4657.054.117 4 WG 210 Powershift Transmission Assembly | Complete Unit

Overview

This ZF 4657.054.117 4 WG 210 Powershift Transmission Assembly is a complete, factory-matched unit designed for heavy-duty off-highway 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 ready-to-install package. The SKU 4657.054.117 replaces worn or failed assemblies, restoring full power flow from the engine to the driveline. This unit sits between the engine bellhousing and the output yoke, directly coupling to the 4657101059: TRANSMISSION HOUSING and the 4657201132: HOUS.FRONT SECT to form the sealed main case.

Symptoms of Failure

• Erratic gear engagement under load: When the internal clutch packs or sprag clutches wear, the transmission may slip or fail to hold gear during uphill pulls or heavy digging, often accompanied by a burning clutch smell.
• Delayed or harsh forward/reverse shifting: Worn seals or scored valve bodies inside the assembly cause pressure loss, resulting in a noticeable lag when shifting from neutral to drive or reverse.
• External fluid leaks at the housing seam: Cracks or gasket failure where the main housing meets the 4657201103: HOUSING REAR PART can cause ATF to drip onto the bellhousing, leading to low fluid levels and eventual transmission overheating.
• Unusual whining or grinding noises: Bearing failure within the planetary gearset produces a metallic whine that increases with engine RPM, indicating imminent internal damage.

Technical Specifications

Compatibility

This complete assembly is engineered for the ZF WG 210 series, but it also fits earlier WG 180 and WG 200 variants with minor adapter modifications. It is commonly used in ZF 4WG-210, 4WG-200, and 4WG-180 powershift transmissions found in telescopic handlers, wheel loaders, and agricultural tractors. The unit is designed to bolt directly to the 4472239184: HOUSING REAR PART without additional machining.

Frequently Asked Questions

Q: Can this 4657.054.117 assembly be rebuilt, or must it be replaced as a unit?
A: While individual clutch packs and seals can be serviced, the complete assembly is factory-balanced and pressure-tested. For most field repairs, replacing the entire unit with this SKU ensures reliable performance without the risk of hidden wear in the planetary carriers.

Q: Does this transmission assembly include the torque converter?
A: Yes, the 4 WG 210 complete unit ships with the integrated torque converter and all internal rotating components. You will only need to transfer the external HOUS.FRONT SECT and bellhousing from your old unit.

Q: What is the typical lead time for this part?
A: As a complete assembly, stock levels vary. We recommend verifying availability before ordering, as the unit requires special crating due to its 195 kg weight.
