ZF 0501.314.853 OUTER CLUTCH DISK for WG100 | OEM Genuine Part

Overview

The ZF 0501.314.853 Outer Clutch Disk is a critical friction component engineered for the WG 100 series automatic transmission. This OEM genuine part sits within the clutch pack assembly, where it transfers torque between rotating and stationary elements during gear shifts. As a wear-sensitive component, the 0501.314.853 ensures smooth engagement and disengagement of planetary gear sets. The SKU 0501.314.853 is manufactured to ZF’s exacting tolerances, guaranteeing a direct fit and reliable performance in heavy-duty industrial applications. This disk works in concert with the TRANSMISSION HOUSING (4651101007) to maintain proper hydraulic pressure and alignment within the clutch drum.

Symptoms of Failure

• Delayed or harsh gear engagement: When the outer clutch disk wears, hydraulic pressure drops, causing noticeable hesitation or jerking when shifting from neutral to drive or reverse.
• Transmission slipping under load: A worn 0501.314.853 cannot hold torque, leading to RPM flare without corresponding vehicle movement, especially during uphill climbs or heavy hauling.
• Burning smell or discolored fluid: Friction material degradation produces a distinct burnt odor and darkens the transmission oil, indicating imminent clutch failure.
• Erratic shift patterns: Worn disks cause inconsistent clutch pack pressure, resulting in unpredictable upshifts or downshifts during operation.

Technical Specifications

Compatibility

This outer clutch disk is primarily designed for the ZF WG 100 series transmission, but it also fits select variants of the WG 180 and WG 200 models due to shared clutch pack architecture. Always verify spline count and stack height against your specific transmission model. The disk interfaces directly with the HOUSING (4651301029) and the HOUSING (4651301024) to form the complete clutch drum assembly. Proper sealing is ensured by the O-RING (0634303928) which prevents fluid bypass around the piston.
