Overview
The ZF 4657.055.107 5 WG 210 Powershift Transmission Assembly | Complete Unit is a fully integrated, factory-matched gearbox core designed for heavy-duty off-highway machinery. This complete unit serves as the central power distribution hub within the WG 210 series, managing torque flow from the engine through multiple clutch packs to the output shaft. As a remanufactured or new complete assembly, SKU 4657.055.107 eliminates the need for piecemeal repairs by providing a drop-in replacement that restores original ZF performance. The assembly integrates directly with the 4657101082: TRANSMISSION HOUSING and the 4657201166: HOUS.FRONT SECT to create a sealed, pressurized oil circuit essential for clutch engagement.
Symptoms of Failure
When the ZF 4657.055.107 complete unit begins to fail, operators typically notice these specific warning signs:
- Delayed or harsh gear engagement: The transmission hesitates before engaging forward or reverse, often accompanied by a jarring shift. This indicates internal clutch pack wear or hydraulic pressure loss within the assembly.
- External oil seepage at housing joints: Leaks develop between the main housing and the 4657201170: HOUSING REAR PART or the 4657298102: HOUSING REAR SECTION, leading to low fluid levels and eventual overheating.
- Intermittent power loss under load: The machine loses pulling power when climbing grades or pushing heavy material, a classic symptom of worn clutches or a failing torque converter inside the complete unit.
- Unusual whining or grinding noises: Metallic sounds from the transmission center section suggest bearing failure or gear tooth damage, requiring immediate replacement of the entire assembly.
