ZF 4657.054.304 4 WG 210 Powershift Transmission Assembly | Complete Unit

Overview

This complete ZF 4657.054.304 4 WG 210 Powershift Transmission Assembly is a fully integrated unit designed for heavy-duty off-highway machinery. As a complete assembly, it serves as the central power distribution hub, converting engine torque into controlled hydraulic and mechanical output for loader, dozer, and grader applications. The SKU 4657.054.304 is a direct replacement for the WG 210 series, ensuring seamless integration with existing drivelines. This unit incorporates the main gear train, clutch packs, and valve body, and it is structurally supported by the TRANSMISSION HOUSING which encloses the rotating components.

Symptoms of Failure

When the ZF 4657.054.304 assembly begins to fail, operators typically notice specific performance degradation. Delayed engagement or gear slipping under load is a primary indicator, often caused by worn clutch discs or degraded seals within the unit. Another common symptom is external oil leakage around the housing seams, which can originate from the interface between the HOUS.FRONT SECT and the main body. You may also experience erratic shifting or harsh engagement due to internal hydraulic pressure loss. Finally, unusual whining or grinding noises from the transmission bell housing indicate bearing or gear damage within the complete assembly.

Technical Specifications

Compatibility

This complete assembly is engineered for the ZF WG 210 series, but it also shares mounting and hydraulic architecture with other ZF powershift models. It is directly compatible with the WG 180 and WG 200 series transmissions when used as a complete unit replacement. Additionally, it can be adapted for use in WG 211 and WG 212 variants with minor modifications to the rear mounting points. The assembly integrates with the HOUSING REAR PART and the HOUSING REAR SECTION to complete the driveline enclosure.
