ZF 4657.054.118 4 WG 210 Powershift Transmission Assembly | Complete Unit

Overview

This ZF 4657.054.118 4 WG 210 Powershift Transmission Assembly is a complete, factory-matched unit designed for heavy-duty off-highway applications. As the core power transfer module in the WG 210 series, this assembly integrates the torque converter, clutch packs, and planetary gear sets into a single, ready-to-install package. The SKU 4657.054.118 is the direct replacement for original equipment transmissions in articulated dump trucks, wheel loaders, and graders. It sits between the engine flywheel and the driveline, managing all gear ratio changes under full load without interrupting power flow. This complete unit eliminates the need for piecemeal rebuilding, offering a drop-in solution that restores original performance specifications.

Symptoms of Failure

When the ZF 4657.054.118 assembly begins to fail, operators typically notice delayed engagement when shifting from neutral to forward or reverse, often accompanied by a harsh clunk. Another common sign is intermittent gear slipping under heavy load, particularly when climbing grades or pushing material, which indicates worn clutch discs or degraded sealing rings. External oil leaks at the housing mating surfaces are frequently observed, especially around the bell housing area, as gaskets and seals harden over time. Finally, erratic shift patterns or a loss of high-range gears point to internal hydraulic pressure loss, often traced back to a failing valve body or worn pump components within the assembly.

Technical Specifications

Compatibility

This complete unit is engineered specifically for the ZF WG 210 series of powershift transmissions. It is a direct fit for models including the WG 180, WG 200, and WG 210 found in construction and mining equipment. The assembly is also compatible with certain WG 160 variants that share the same bell housing bolt pattern and input shaft spline count. Always verify your transmission model tag before installation, as internal gear ratios may vary between series generations.

During installation, this transmission assembly mates directly to the TRANSMISSION HOUSING which provides the structural backbone for the entire drivetrain. The front section is sealed by the HOUS.FRONT SECT, while the rear of the unit is enclosed by the HOUSING REAR PART. For certain WG 210 configurations, an alternative rear cover is the HOUSING REAR PART, which accommodates different PTO mounting options.

Frequently Asked Questions

Q: Is the 4657.054.118 a direct bolt-in replacement for my existing WG 210 transmission?
A: Yes, this complete assembly is designed as a 1:1 replacement for original ZF WG 210 units. It includes all internal components pre-assembled and tested, requiring only the transfer of external sensors and your existing bell housing.

Q: What is the typical service life of this complete transmission assembly?
A: Under normal operating conditions with proper maintenance, this unit can provide 8,000 to 12,000 hours of service. Factors such as load cycles, fluid quality, and operating temperature significantly impact longevity.

Q: Do I need to replace the housing components when installing this assembly?
A: It is strongly recommended to inspect and replace the HOUS.FRONT SECT and both rear housing options (4657201103 and 4472239184) if they show signs of wear or corrosion, as they directly affect alignment and sealing.
