Overview
This complete ZF 4657.024.310 4 WG 190 Powershift Transmission Assembly is a fully integrated unit designed for heavy-duty off-highway applications. As the core power transfer module in the WG 190 series, it manages gear selection and torque distribution under extreme loads. The assembly includes the main gear set, clutch packs, and hydraulic control components. The SKU 4657.024.310 is a direct replacement for original equipment units, ensuring seamless installation. It works in concert with the 4657101085 TRANSMISSION HOUSING to protect internal components from debris and stress.
Symptoms of Failure
- Delayed or harsh shifting: Worn clutch packs or valve body issues cause hesitation between gears, often accompanied by a jarring engagement.
- Transmission fluid leaks at housing seams: Cracks or warping in the 4657201161 HOUS.FRONT SECT or rear sections allow oil to escape, leading to low fluid levels and overheating.
- Gear slippage under load: Internal wear reduces clamping force, causing the transmission to lose power transfer when climbing or hauling.
- Unusual whining or grinding noises: Bearing failure or gear tooth damage produces metallic sounds, especially during deceleration or turns.

Frequently Asked Questions
Q: Can this unit be installed without replacing the housing sections?
A: Yes, but we strongly recommend inspecting the 4657101085 TRANSMISSION HOUSING and both rear sections for cracks or wear before reuse. Damaged housings can cause misalignment and premature failure.
Q: What is the typical service life of this assembly?
A: Under normal operating conditions with proper fluid maintenance, the ZF 4657.024.310 can last 8,000–12,000 hours. Harsh environments or frequent heavy loads may reduce this interval.
Q: Are the screen sheets included with the complete unit?
A: No. The 4657301032 SCREEN SHEET and 4657301033 SCREEN SHEET are sold separately. They must be replaced during assembly to prevent contamination.
