Overview
The ZF 0501.332.239 Outer Clutch Disk is a critical friction component engineered for the WG100, WG130, and WG131 series transmissions. Positioned within the clutch pack assembly, this OEM genuine part transfers torque between rotating shafts and stationary housings during gear engagement. The SKU 0501.332.239 ensures precise hydraulic pressure application, enabling smooth power flow through the drivetrain. When paired with the 2093109006 DIFFERENTIAL, this disk maintains consistent load distribution across the transmission’s planetary gear sets.
Symptoms of Failure
- Delayed or harsh gear engagement: Worn friction material on the 0501.332.239 causes slipping during shifts, especially under load in WG100 transmissions.
- Transmission overheating: Excessive heat buildup occurs when the outer clutch disk fails to disengage fully, often accompanied by burnt oil smell.
- Erratic shifting under acceleration: A degraded disk leads to intermittent power loss, particularly when climbing grades or towing heavy loads.
- Metallic debris in transmission fluid: Flaking friction material from the 0501.332.239 contaminates the hydraulic circuit, accelerating wear on the 0750117075 TAPER ROLLER BEARING.

Frequently Asked Questions
Q: Can the 0501.332.239 be used in a WG180 transmission?
A: No. This outer clutch disk is dimensionally specific to WG100, WG130, and WG131 models. WG180 units require a larger diameter friction disk (part number 0501.332.289).
Q: How often should I replace the outer clutch disk?
A: ZF recommends inspection every 2,000 operating hours. Replace the 0501.332.239 if friction material thickness measures below 2.8 mm or if glazing is visible.
Q: Does this part include the snap ring?
A: No. The 0501.332.239 is sold as a single friction disk. The retaining snap ring must be ordered separately (ZF part number 0631100223).
