Overview
This ZF 0501.342.846 LINED 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 from the engine to the gearbox input shaft, enabling smooth gear engagement and reliable power delivery under heavy-duty cycles. The SKU 0501.342.846 is manufactured to ZF’s original tolerances, ensuring consistent clamping force and heat dissipation during high-load operations. When paired with a properly torqued 2093109063: DIFFERENTIAL, this disk maintains driveline integrity across demanding industrial applications.
Symptoms of Failure
- Transmission gear slipping under load: A worn lined clutch disk loses friction coefficient, causing the transmission to slip between gears when accelerating or climbing. This often manifests as a sudden RPM flare without corresponding vehicle speed increase.
- Delayed or harsh engagement: When the friction lining degrades, the clutch pack takes longer to lock up, resulting in a noticeable lag or a jarring shift from neutral to drive. Operators may report a “clunk” during gear changes.
- Burning odor or dark transmission fluid: Excessive heat from a glazed or worn disk generates a distinct burnt smell. Fluid may appear dark or contain metallic particles, indicating the friction material has broken down.
- Reduced power transfer efficiency: A failing disk cannot transmit full engine torque, leading to sluggish performance and increased fuel consumption. This symptom is often mistaken for engine trouble but originates in the clutch pack.

Compatibility
This lined clutch disk is designed exclusively for ZF WG-series powershift transmissions. Verified compatible models include WG100, WG130, and WG131. It may also fit WG150 and WG180 variants where the clutch pack dimensions match, though cross-referencing with the 0750117075: TAPER ROLLER BEARING and 2093209094: DIFFERENTIAL is recommended for assembly verification. Always confirm the spline count and stack height against your transmission’s service manual before installation.

Frequently Asked Questions
Q: Can the 0501.342.846 clutch disk be resurfaced or relined?
A: ZF does not recommend relining this disk. The OEM friction material is bonded under specific pressure and temperature cycles. Relining may alter the stack height, leading to improper clutch pack clearance and premature failure of components like the 2093309078: DIFF.HOUSING.
Q: How do I know if this disk fits my WG130 transmission?
A: Verify your transmission’s serial number and clutch pack count. The 0501.342.846 is the standard lined disk for WG130 units with 24-spline hubs. If your unit uses a different spline count, you may need the 2097309085: DIFFERENTIAL AXLE adapter kit.
Q: What is the typical service interval for this clutch disk?
A: In normal industrial use (e.g., forklifts, loaders), replacement is recommended every 4,000–6,000 operating hours. Heavy shock loading or frequent direction changes can reduce this interval. Always inspect the 0750117075: TAPER ROLLER BEARING during clutch replacement.
