Overview
This complete ZF 4657.024.114 4 WG 190 Powershift Transmission Assembly is a fully integrated unit designed for heavy-duty off-highway machinery. As the core power transfer module in the WG 190 series, it manages gear engagement and torque distribution under extreme loads. The SKU 4657.024.114 replaces the entire assembly, ensuring seamless integration with existing drivelines. It works in concert with the 4657101051: TRANSMISSION HOUSING to protect internal components from debris and stress.
Symptoms of Failure
- Erratic gear engagement under load: When the assembly wears, operators experience delayed or harsh shifting during uphill climbs or heavy hauling, often accompanied by a grinding noise.
- Torque converter shudder: A persistent vibration at low RPM indicates internal clutch pack wear, reducing power delivery efficiency.
- Hydraulic fluid contamination: Metal particles in the oil filter signal bearing or gear degradation, leading to pressure drops and eventual transmission lockup.
- Oil leaks from the bell housing: Cracked seals around the 4657201151: HOUS.FRONT SECT cause fluid loss, overheating, and slipping in high-range gears.

Frequently Asked Questions
Q: Can I install this 4657.024.114 assembly without replacing the housing?
A: It is strongly recommended to replace the TRANSMISSION HOUSING simultaneously, as worn bolt threads and mating surfaces can cause oil leaks and misalignment.
Q: What is the typical lifespan of this WG 190 powershift unit?
A: With proper maintenance and clean hydraulic fluid, the assembly lasts 8,000–12,000 operating hours. Failure symptoms like shudder or slipping often appear after 6,000 hours.
Q: Does this part include the torque converter?
A: Yes, the complete unit includes the torque converter and all internal clutch packs. You only need to add the HOUS.FRONT SECT if the original front section is damaged.
