Overview
The ZF 4143.351.077 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 engages and disengages torque flow between planetary gear sets. The SKU 4143.351.077 ensures precise hydraulic pressure distribution, enabling smooth gear shifts under heavy industrial loads. When installed alongside the 4143101025 HOUSING, this disk maintains proper alignment within the clutch drum, preventing premature wear on adjacent components.
Symptoms of Failure
- Erratic gear engagement or slipping under load – Worn friction material on the 4143.351.077 disk reduces clamping force, causing the transmission to hesitate or slip during acceleration.
- Darkened or burnt transmission fluid – Overheated clutch disks generate excessive friction particles, turning the oil a dark brown or burnt smell.
- Delayed shifting between forward and reverse – A degraded outer clutch disk fails to release quickly, leading to harsh or delayed gear changes.
- Metallic grinding noise during operation – When the friction lining is completely worn, the steel core contacts the 4143301055 HOUSING, producing audible metal-on-metal sounds.

Compatibility
This outer clutch disk is designed for ZF HL 100 and HL 270 series transmissions, commonly found in WG180, WG200, and WG250 models. It also fits select ZF 4HP22 and 5HP24 industrial gearboxes where the clutch pack uses a 180mm outer diameter disk. For proper installation, ensure the 4143298040 CASE is free of scoring, and replace the 0631329135 SPRING PIN to secure the disk stack.
