Overview
The ZF 4143.352.027 OUTER CLUTCH DISK is a critical friction component engineered for the HL 100 and HL 270 series transmissions. Positioned within the clutch pack assembly, this OEM genuine part transfers torque between rotating shafts during gear engagement. The SKU 4143.352.027 interfaces directly with the 4143101016 HOUSING and the 4143301039 HOUSING, ensuring precise alignment under high-load conditions. Its hardened steel core and specialized friction lining provide consistent clamping force, making it indispensable for maintaining hydraulic clutch modulation in heavy-duty industrial drivetrains.
Symptoms of Failure
- Delayed gear engagement or slipping under load: Worn friction material on the outer clutch disk reduces bite, causing the transmission to hesitate or slip when shifting from neutral to drive.
- Erratic shift quality with shuddering: Uneven wear patterns create vibration during clutch pack lockup, often felt as a shudder during low-speed maneuvers.
- Burnt transmission fluid odor: Excessive heat from friction surface degradation generates a distinct burnt smell, indicating the disk has exceeded its thermal capacity.
- Metallic debris in the oil pan: Flaking friction material or steel backing wear produces visible particles during routine fluid changes, signaling imminent clutch pack failure.

Compatibility
This outer clutch disk is engineered for ZF HL 100 and HL 270 series transmissions, including models such as WG180, WG200, and 4WG-200. It also fits select 5WG-210 variants where the clutch pack uses a 195 mm outer diameter disk. Always verify stack height against the 0501318136 GASKET and 0636101084 CAP SCREW specifications during installation to maintain proper clamping force.
