Overview
This ZF 4657.054.081 4 WG 210 Powershift Transmission Assembly is a complete, factory-grade unit designed for heavy-duty off-highway machinery. As the core power distribution module in the WG 210 series, it manages torque flow and gear selection under extreme loads. The SKU 4657.054.081 integrates directly with the main TRANSMISSION HOUSING to ensure precise alignment of internal shafts and clutches. This assembly replaces worn or failed complete units, restoring full operational efficiency in wheel loaders, dozers, and graders.
Symptoms of Failure
- Delayed or harsh gear engagement: When the internal clutch packs or valve body wear, operators experience a noticeable lag or jarring shift between forward and reverse gears.
- Low hydraulic pressure and overheating: A failing assembly often causes insufficient oil flow, leading to transmission temperatures exceeding 120°C and eventual seal degradation.
- Oil leaks from the bell housing or output flange: Worn gaskets or cracked casings allow ATF to escape, leaving puddles under the machine and reducing lubrication to critical components.
- Unusual whining or grinding noises: Damaged planetary gears or bearing surfaces produce metallic sounds during acceleration or deceleration, indicating imminent internal failure.

Compatibility
This complete unit is engineered for the ZF WG 210 series, but its mounting pattern and hydraulic circuit also suit the WG 180 and WG 200 families when paired with the correct HOUS.FRONT SECT and HOUSING REAR PART. It directly replaces units in ZF 4WG-210, 4WG-200, and 4WG-180 transmissions found in Volvo L220, Caterpillar 966, and Komatsu WA500 loaders. Always verify the CYLINDRICAL PIN alignment before installation to ensure correct dowel engagement.

Frequently Asked Questions
Q: Does this assembly include the torque converter?
A: No, the 4657.054.081 is the complete transmission gearbox section only. The torque converter is housed in the HOUS.FRONT SECT, which must be ordered separately if needed.
Q: Can I install this unit without removing the cab or engine?
A: In most wheel loaders, yes. The complete unit slides out from underneath after disconnecting the driveshafts and oil lines. However, you must support the HOUSING REAR PART to avoid bending the output flange.
Q: What is the typical lead time for this SKU?
A: As a complete assembly, the 4657.054.081 is typically stocked and ships within 1–3 business days. Verify stock status at time of order.
