ZF 4143.351.035 OUTER CLUTCH DISK for HL 100/HL 270 | OEM Genuine Part

Overview

The ZF 4143.351.035 OUTER CLUTCH DISK is a critical friction component engineered for the HL 100 and HL 270 series transmissions. This genuine OEM part sits within the clutch pack assembly, where it engages and disengages torque flow between planetary gear sets. The SKU 4143.351.035 is specifically designed to withstand high thermal loads and shear forces, ensuring precise gear engagement in heavy-duty industrial applications. When installed alongside the 4143101016 HOUSING, this disk forms the primary torque-transfer interface within the clutch drum.

Symptoms of Failure

• Delayed gear engagement or clutch slipping – Worn friction material on the outer clutch disk causes hesitation when shifting, especially under load in HL 270 models.
• Burnt transmission fluid odor – Excessive heat from a glazed or warped 4143.351.035 disk degrades the oil, producing a distinct burnt smell during operation.
• Erratic shifting or harsh engagement – A damaged outer disk creates uneven pressure distribution, leading to jarring shifts or unexpected neutral conditions.
• Metallic debris in the oil pan – As the friction lining wears past its service limit, particles contaminate the fluid, often requiring replacement of the 0501318136 GASKET during cleanup.

Technical Specifications

Compatibility

This outer clutch disk is directly compatible with ZF HL 100 and HL 270 series transmissions. It also fits select variants of the WG180 and WG200 models when used in conjunction with the correct 4143301039 HOUSING. For proper installation, always pair this disk with a new 0636101084 CAP SCREW to maintain clamping force within the clutch pack. The 4143.351.035 is not interchangeable with inner clutch disks; verify your transmission’s stack-up diagram before ordering.
