Overview
The ZF 4645.351.024 Outer Clutch Disk is a critical friction component engineered for the WG100, WG130, and WG131 transmission series. This OEM genuine part sits within the clutch pack assembly, where it transfers torque between rotating shafts during gear engagement. By providing precise frictional grip, it ensures smooth power delivery and prevents slippage under heavy loads. The SKU 4645.351.024 is manufactured to ZF’s exacting tolerances, making it essential for maintaining hydraulic pressure balance inside the clutch drum. When paired with a properly sealed 4143101009: HOUSING and a robust 4143301025: HOUSING, this disk delivers reliable performance in demanding industrial applications.
Symptoms of Failure
- Delayed gear engagement or clutch shudder: Worn friction material causes hesitation when shifting, often accompanied by a vibrating sensation during acceleration.
- Transmission fluid overheating: Slipping disks generate excess heat, leading to burnt-smelling oil and potential damage to the 0634313603: O-RING seals.
- Erratic shift patterns under load: The transmission may unexpectedly drop gears or fail to hold torque, especially when towing or climbing inclines.
- Metallic debris in oil pan: Flaking friction material contaminates the hydraulic circuit, accelerating wear on the 4475280018: SCREW PLUG and valve body components.

Compatibility
This outer clutch disk is specifically designed for ZF’s WG100, WG130, and WG131 powershift transmissions. It also fits select variants of the WG180 and WG200 series when used with the correct 0501342341: SUPPORT RING. Always verify the clutch pack stack height using the 4143298457: SEAL KIT to ensure proper clearance. For complete assembly integrity, replace the 0634313591: O-RING and 0636101068: CAP SCREW during installation. The disk is not backward-compatible with older WG120 models without modifying the 4143221013: THROTTLE VALVE calibration.
