Overview
The ZF 2095.171.011 MAIN CLUTCH is a critical OEM genuine component engineered specifically for the WG100, WG130, and WG131 transmission series. This precision-machined clutch assembly directly controls the engagement and disengagement of engine power to the driveline, ensuring smooth torque transfer and reliable gear shifts under heavy industrial loads. As a direct replacement part, the SKU 2095.171.011 sits within the clutch housing and interfaces with the input shaft, making it essential for maintaining operational efficiency in ZF power take-off (PTO) and transmission systems. When paired with a properly functioning 2095109020: DIFFERENTIAL, the main clutch ensures consistent power delivery to both drive axles.
Symptoms of Failure
- Clutch slippage under load: If the main clutch fails to hold torque, operators will notice engine RPM rising without proportional vehicle speed increase, especially during uphill climbs or heavy hauling.
- Hard shifting or gear grinding: A worn 2095.171.011 main clutch prevents clean disengagement, causing audible grinding noises when shifting between forward and reverse gears.
- Oil contamination in clutch housing: Internal seal degradation leads to transmission fluid mixing with clutch friction material, visible as dark, burnt-smelling oil leaks around the bell housing.
- Intermittent power loss: Partial clutch engagement failure results in sudden loss of drive power, often misdiagnosed as a differential issue until the main clutch is inspected.

Compatibility
This genuine ZF main clutch is engineered for direct fitment in the following transmission models: WG100, WG130, and WG131. It is also compatible with select WG180 and WG200 variants when used with the correct input shaft adapter. The 2095.171.011 clutch assembly works in conjunction with the 0750117075: TAPER ROLLER BEARING to support axial loads during clutch actuation. For complete driveline restoration, verify that the 2095209037: DIFFERENTIAL and 2095309059: DIFF.HOUSING are free from wear before installing this main clutch.
