Overview
The ZF 2095.171.002 MAIN CLUTCH is a critical OEM genuine component engineered specifically for the WG100, WG130, and WG131 transmission series. This part serves as the primary torque-transfer interface between the engine and the gearset, ensuring smooth engagement and disengagement during shifting operations. Positioned within the clutch pack assembly, the SKU 2095.171.002 directly controls power flow, preventing driveline shock and enabling precise modulation of tractive effort. When paired with a properly functioning 5838109007: DIFFERENTIAL, this main clutch maintains consistent load distribution across the axle system.
Symptoms of Failure
- Delayed engagement or clutch slip under load: When the 2095.171.002 wears, operators often report a lag between throttle input and vehicle movement, especially on inclines. This “clutch slipping when accelerating” symptom is a primary indicator of worn friction surfaces.
- Oil contamination or dark hydraulic fluid: A failing main clutch can shed debris into the transmission oil, causing “dark brown transmission fluid” or metallic particles visible during routine checks. This often accompanies degraded 0750117075: TAPER ROLLER BEARING performance.
- Harsh or jerky shifting: Worn clutch plates produce “hard shifting in ZF transmission” complaints, where gear changes become abrupt or accompanied by audible clunking. This symptom worsens as the 2095209019: DIFFERENTIAL experiences uneven torque inputs.
- Intermittent loss of drive: In advanced wear stages, the main clutch may fail to hold engagement, resulting in “transmission losing power intermittently” scenarios, often misdiagnosed as pump failure.

Compatibility
This OEM genuine main clutch is designed for the ZF WG100, WG130, and WG131 series powershift transmissions. It is also compatible with select variants of the WG180 and WG200 models where the clutch pack configuration matches the 2095.171.002 spline count and plate thickness. Always verify the 0631329086: SPRING PIN alignment during installation to ensure proper indexing within the clutch drum. For differential-related assemblies, cross-reference with the 5838300682: DIFFERENTIAL AXLE to confirm compatibility with your specific transmission housing.
