ZF 4143.352.006 OUTER CLUTCH DISK for HL 100/HL 270 | OEM Genuine Part

Overview

The ZF 4143.352.006 OUTER CLUTCH DISK is a critical friction component engineered for the HL 100 and HL 270 series transmissions. This OEM genuine part sits within the clutch pack assembly, where it transfers torque between rotating shafts under hydraulic pressure. The SKU 4143.352.006 is specifically designed to withstand high thermal loads and shear forces, ensuring precise engagement and disengagement in heavy-duty industrial drivetrains. When paired with the 4143101009: HOUSING and 4143301025: HOUSING, this disk maintains proper alignment within the clutch drum, preventing axial play and power loss.

Symptoms of Failure

• Delayed gear engagement or slipping under load — Worn friction material on the outer clutch disk reduces clamping force, causing the transmission to hesitate or slip when shifting from neutral to drive.
• Burnt transmission fluid odor — Excessive heat generated by a glazed or worn disk degrades the ATF, producing a distinct burnt smell during operation.
• Erratic shift quality or harsh engagement — A damaged outer disk creates uneven pressure distribution, leading to jarring shifts or shuddering during acceleration.
• Visible metal debris in the oil pan — As the friction lining wears down, metallic particles contaminate the hydraulic circuit, often accompanied by a failing 0634313603: O-RING that allows fluid bypass.

Technical Specifications

Compatibility

This outer clutch disk is a direct replacement for ZF transmissions in the HL 100 and HL 270 series. It is also compatible with the WG180, WG200, and WG210 models where the clutch pack uses a 195 mm outer diameter disk. Always verify stack height using the 0501342341: SUPPORT RING and replace the 4475280018: SCREW PLUG during reassembly to prevent pressure loss. For complete overhaul, order the 4143298457: SEAL KIT to refresh all hydraulic seals simultaneously.
