Overview
The ZF 4143.351.075 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. Its hardened steel core and specialized friction lining ensure consistent pressure distribution and heat dissipation under heavy loads. The SKU 4143.351.075 directly replaces worn disks to restore hydraulic clutch modulation. When paired with the 4143101025: HOUSING and 4143301055: HOUSING, this disk maintains proper clearance within the clutch drum assembly.
Symptoms of Failure
- Delayed gear engagement: Worn friction material causes a noticeable lag when shifting from neutral to drive or reverse, often accompanied by a soft “clunk.”
- Transmission slipping under load: The outer clutch disk loses its grip, causing engine RPM to rise without proportional vehicle acceleration, especially on inclines.
- Burnt transmission fluid odor: Overheated friction material degrades the ATF, producing a sharp, acrid smell and darkening the fluid color.
- Erratic shift quality: Harsh or flared shifts occur as the disk fails to hold pressure, leading to inconsistent clutch pack compression.

Compatibility
This outer clutch disk is designed for ZF HL 100 and HL 270 series transmissions, including models such as the WG180, WG200, and WG210. It also fits select 4HP and 5HP variants used in industrial and marine applications. For proper installation, verify that the 4143298040: CASE is free of scoring and that the 0631329135: SPRING PIN is replaced to secure the clutch drum alignment. Always measure clutch pack clearance after installing this disk to avoid premature wear.
