Overview
This ZF 4657.054.195 4 WG 210 Powershift Transmission Assembly is a complete, factory-grade unit designed for heavy-duty off-highway machinery. As the core power transfer module in the WG 210 series, this assembly integrates the main gear sets, clutch packs, and hydraulic control valves into a single, ready-to-install package. The SKU 4657.054.195 serves as the direct replacement for worn or failed transmissions in articulated dump trucks, wheel loaders, and graders. It sits at the heart of the driveline, converting engine torque into smooth, multi-speed forward and reverse motion. For maximum structural integrity, this unit is engineered to be paired with the 4657101078: TRANSMISSION HOUSING which provides the rigid outer shell, while the 4657201166: HOUS.FRONT SECT and 4657201168: HOUSING REAR PART enclose the internal rotating components.
Symptoms of Failure
- Delayed or harsh gear engagement: When the internal clutch packs or seals degrade, operators experience a noticeable lag or a jarring “clunk” when shifting between forward and reverse, indicating internal hydraulic pressure loss.
- Torque converter shudder under load: A vibration or shudder during acceleration, especially on inclines, points to worn stator bearings or damaged turbine splines within the assembly.
- External oil leaks near the bell housing: Fluid weeping from the front pump seal or the joint between the main case and the 4657298101: HOUSING REAR SECTION is a clear sign of gasket failure or housing fatigue.
- Intermittent power loss or gear slipping: The transmission may momentarily lose drive in a specific gear range, often accompanied by a burning smell from overheated friction discs.
