ZF 4657.054.305 4 WG 210 Powershift Transmission Assembly | Complete Unit

Overview

The ZF 4657.054.305 4 WG 210 Powershift Transmission Assembly is a complete, factory-matched unit designed for heavy-duty off-highway machinery. This assembly integrates the main gear cluster, clutch packs, and hydraulic control components into a single, ready-to-install package. As the core power transfer module in the WG 210 series, it replaces worn or failed internal assemblies without requiring piecemeal rebuilding. The SKU 4657.054.305 is the definitive reference for this complete unit, ensuring you receive the exact rotating assembly needed for a direct swap.

Symptoms of Failure

When the ZF 4657.054.305 assembly begins to fail, operators often notice these specific warning signs:

• Erratic gear engagement or slipping under load: The transmission may hesitate or fail to hold a gear when pushing heavy material, indicating worn clutch discs or seal degradation inside the assembly.
• Contaminated transmission fluid with metallic debris: Finding silver or bronze particles in the oil filter or sump points to bearing or gear surface fatigue within the unit.
• Audible whining or grinding from the bell housing: A high-pitched noise during acceleration or deceleration suggests worn planetary gears or damaged thrust washers.
• Delayed or no reverse engagement: If the machine moves forward but struggles to reverse, the internal hydraulic circuit or clutch pack specific to reverse has likely failed.

Technical Specifications

Compatibility

This complete assembly is engineered for the ZF WG 210 series of powershift transmissions. It is directly compatible with models such as the WG 180, WG 200, and WG 210 found in loaders, graders, and material handlers. The unit also fits select variants of the 4 WG 210 used in agricultural tractors and industrial forklifts. Always verify your transmission serial number against the 4657.054.305 specification to confirm fitment.

Frequently Asked Questions

Q: Can the 4657.054.305 assembly be rebuilt, or is it a sealed unit?
A: This is a complete, factory-sealed assembly designed for direct replacement. While internal components like clutch discs are serviceable, the unit is typically swapped as a whole to minimize downtime. We recommend replacing the TRANSMISSION HOUSING and HOUS.FRONT SECT simultaneously for optimal sealing.

Q: What is the typical lifespan of this assembly in a wheel loader?
A: Under normal operating conditions with proper maintenance, the 4 WG 210 assembly can last 8,000–12,000 hours. Early failure often stems from contaminated fluid or neglected filter changes. Always inspect the SCREEN SHEET and SCREEN SHEET during installation.

Q: Does this part include the torque converter?
A: No, the 4657.054.305 is the transmission assembly only. It does not include the torque converter or flex plate. You will need to order those separately based on your engine model.
