Overview
This complete ZF 4657.054.165 4 WG 210 Powershift Transmission Assembly is a fully integrated unit designed for heavy-duty industrial and agricultural machinery. As the core power transfer module in the WG 210 series, it manages gear engagement and torque distribution under high-stress conditions. The assembly includes the main housing and internal rotating components, ensuring seamless shifting in loaders, forklifts, and off-highway vehicles. The SKU 4657.054.165 is a direct OEM replacement unit, built to restore original performance without requiring partial rebuilds.
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, especially under load.
- Transmission fluid leaks near the bell housing: Degraded seals or a cracked TRANSMISSION HOUSING can cause oil to weep from the front or rear mating surfaces, leading to low fluid levels and overheating.
- Intermittent power loss or slipping: Worn planetary gears or damaged friction discs result in the engine revving without proportional vehicle movement, particularly during uphill travel or heavy towing.
- Unusual grinding or whining noises: Bearing failure or misalignment in the HOUS.FRONT SECT produces metallic sounds that intensify with speed changes.

Frequently Asked Questions
Q: Is the 4657.054.165 a direct bolt-in replacement for a worn WG210 unit?
A: Yes, this complete assembly includes all internal components pre-assembled. It replaces the entire transmission core without needing to transfer parts from the old unit, provided the external housing sections (HOUS.FRONT SECT and HOUSING REAR PART) are in good condition.
Q: What fluid type does this powershift assembly require?
A: ZF recommends using a Dexron III or ZF TE-ML 03D approved transmission fluid. The unit holds approximately 12.5 liters. Always check the dipstick after installation and top off as needed.
Q: Can I install this unit without replacing the rear housing sections?
A: It is strongly advised to inspect the HOUSING REAR SECTION and all sealing surfaces. If there is any scoring or corrosion, replace them simultaneously to prevent future oil leaks and misalignment.
