ZF 4143.352.058 OUTER CLUTCH DISK for HL 100/HL 270 | OEM Genuine Part

Overview

The ZF 4143.352.058 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 4143.352.058, sits within the clutch pack assembly, where it transfers torque between rotating shafts during gear engagement. It interfaces directly with the 4143101022: HOUSING and the 4143301044: HOUSING, providing the necessary friction surface for smooth power flow. Without this disk, the transmission cannot lock or release clutch packs reliably, leading to immediate drivability issues.

Symptoms of Failure

When the ZF 4143.352.058 outer clutch disk wears out, operators typically notice these specific failure modes:

• Delayed gear engagement or slipping under load – The disk loses friction material, causing the clutch pack to slip when accelerating or climbing.
• Erratic shifting and harsh gear changes – Worn disks create uneven pressure distribution, leading to jarring shifts.
• Burnt transmission fluid odor – Excessive heat from slipping friction surfaces degrades the oil, producing a distinct burnt smell.
• Visible metal debris in the oil pan – As the friction material wears away, fine metallic particles contaminate the hydraulic system.

Technical Specifications

Compatibility

This outer clutch disk is designed for ZF HL 100 and HL 270 series transmissions. It is also compatible with the following ZF models that share the same clutch pack architecture: WG180, WG200, WG210, WG250, and WG280. Always verify your transmission serial number before ordering. The disk works in conjunction with the 0631329135: SPRING PIN and 0636302014: SCREW PLUG to secure the clutch pack assembly.
