Overview
The ZF 4143.351.034 OUTER CLUTCH DISK is a critical friction component engineered for the HL 100 and HL 270 series transmissions. This OEM genuine part, identified by SKU 4143.351.034, sits within the clutch pack assembly, where it transfers torque between rotating and stationary elements during gear shifts. It interfaces directly with the 4143101016: HOUSING and the 4143301039: HOUSING, ensuring precise alignment and load distribution. The disk’s friction lining is formulated to withstand high thermal loads, making it essential for smooth engagement and long service life in heavy-duty industrial applications.
Symptoms of Failure
- Erratic gear engagement or slipping under load: Worn friction material on the outer clutch disk causes the transmission to hesitate or lose torque during acceleration, a common issue in HL 270 series units.
- Delayed shifting or harsh engagement: As the disk degrades, hydraulic pressure struggles to lock the clutch pack, leading to noticeable lag or jarring shifts, especially in WG180 and WG200 models.
- Metallic debris in transmission fluid: Flaking or chipped friction material from the 4143.351.034 disk contaminates the oil, often accompanied by a burnt smell and reduced hydraulic efficiency.
- Overheating of the clutch housing: Insufficient friction grip forces the system to slip more, generating excess heat that can warp adjacent components like the 0501318136: GASKET and 0636101084: CAP SCREW.

Compatibility
This outer clutch disk is specifically designed for the ZF HL 100 and HL 270 series transmissions, which are widely used in off-highway vehicles, construction equipment, and marine applications. It is also compatible with the WG180 and WG200 series, where it serves as a direct replacement in the forward clutch pack. Always verify the stack height and spline count against your transmission’s service manual before installation. For complete assembly, pair this disk with the 4143101016: HOUSING and 4143301039: HOUSING to ensure proper clearance.
