Overview
The ZF 4657.055.314 5 WG 210 Powershift Transmission Assembly is a complete, factory-grade unit designed for heavy-duty off-highway applications. This assembly serves as the primary torque-converter and gearbox module within the WG 210 series, managing power distribution from the engine to the driveline under extreme load conditions. The SKU 4657.055.314 integrates the main housing, clutch packs, and hydraulic control circuits into a single ready-to-install package. When rebuilding or replacing a worn unit, this complete assembly eliminates the need for piecemeal component sourcing, ensuring correct alignment of internal shafts and valve bodies. For optimal sealing and structural integrity during installation, always pair this unit with a new 0634313603: O-RING and the correct 0636115293: 螺栓 fasteners to secure the front section.
Symptoms of Failure
- Delayed engagement or gear slipping under load: When the internal clutch packs or torque converter stator wear, the 4657.055.314 assembly may fail to transmit full torque, causing hesitation during forward-reverse shifts.
- External oil leaks near the front housing interface: Degraded seals or a cracked 4657201161: HOUS.FRONT SECT can allow transmission fluid to escape, leading to low pressure and eventual overheating.
- Unusual whining or grinding noises from the bell housing: Worn bearings or a misaligned 0631306816: CYLINDRICAL PIN can create metal-on-metal contact, accelerating internal damage.
- Erratic shifting or loss of power in lower gears: Hydraulic blockages or a failing oil feed housing often manifest as inconsistent clutch application, particularly in the 2nd and 3rd gear ranges.

Compatibility
This complete unit is engineered specifically for the ZF WG 210 series powershift transmissions. It is directly compatible with models including WG180, WG200, and WG210 variants used in construction loaders, graders, and material handlers. The 4657.055.314 assembly also fits select retrofit applications where the original WG 180 housing has been upgraded. For proper installation, ensure the mating 4657201161: HOUS.FRONT SECT is free of cracks and that the 0631306816: CYLINDRICAL PIN is correctly seated to prevent misalignment. Always replace the 0634313603: O-RING and 0636115293: 螺栓 during reassembly to maintain factory torque specs.
