ZF 0501.326.368 OUTER CLUTCH DISK for WG100/WG130/WG131 | OEM Genuine Part

Overview

The ZF 0501.326.368 OUTER CLUTCH DISK is a critical friction component engineered for the WG100, WG130, and WG131 transmission series. Positioned within the clutch pack assembly, this OEM genuine part transfers torque between rotating shafts during gear engagement, ensuring smooth power delivery under heavy loads. The SKU 0501.326.368 is precision-machined to ZF’s original tolerances, directly interfacing with the 2095109009 DIFFERENTIAL and the 0750117075 TAPER ROLLER BEARING to maintain driveline stability. Without this disk, hydraulic pressure cannot properly lock clutch packs, leading to torque loss and eventual transmission failure.

Symptoms of Failure

• Delayed gear engagement or clutch shudder – Worn friction material on the 0501.326.368 causes hesitation when shifting, especially under load.
• Transmission overheating – Slipping outer clutch disk generates excessive heat, often accompanied by burnt oil smell.
• Erratic shift quality – Hard or soft shifts occur as the disk fails to hold pressure, affecting the 2095209037 DIFFERENTIAL and overall gear synchronization.
• Metallic debris in transmission fluid – Flaking friction lining contaminates the oil, accelerating wear on the 2095309059 DIFF.HOUSING and adjacent bearings.

Technical Specifications

Compatibility

This outer clutch disk is specifically designed for ZF WG100, WG130, and WG131 transmissions. It also fits select variants of the WG180 and WG200 series when used in low-range clutch packs. Always verify spline count and stack height against your existing assembly. The disk works in conjunction with the 0631329086 SPRING PIN and 0730300820 THRUST WASHER to secure the clutch pack. For heavy-duty applications, pairing with the 4482360002 AXLE BEVEL GEAR ensures proper load distribution.
