ZF 4143.351.080 OUTER CLUTCH DISK for HL 100/HL 270 | OEM Genuine Part

Overview

The ZF 4143.351.080 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 with the inner hub to transfer torque from the engine to the driveline. Designed to withstand high thermal loads and repetitive engagement cycles, the 4143.351.080 ensures smooth power delivery and precise gear selection. When paired with the 4143101025 HOUSING and 4143301055 HOUSING, this outer clutch disk forms the core of the clutch pack system, directly influencing shift quality and transmission longevity.

Symptoms of Failure

• Delayed or harsh shifting: Worn friction material on the outer clutch disk causes hesitation between gear changes, often accompanied by a noticeable jolt during engagement.
• Transmission slipping under load: When the disk loses its friction coefficient, the transmission may momentarily lose power transfer, especially during uphill climbs or heavy hauling.
• Burning smell from transmission fluid: Excessive heat generated by a glazed or worn outer clutch disk leads to fluid degradation and a distinct burnt odor.
• Metallic debris in the oil pan: As the disk wears, fine metal particles from the friction lining contaminate the hydraulic fluid, often visible during routine maintenance.

Technical Specifications

Compatibility

This outer clutch disk is specifically designed for ZF HL 100 and HL 270 series transmissions, which are commonly found in industrial forklifts, agricultural tractors, and construction loaders. It is also compatible with ZF WG180, WG200, and WG210 models that utilize the same clutch pack architecture. For proper installation, ensure the 4143298040 CASE is free of scoring and that the 0631329135 SPRING PIN is replaced to secure the disk hub alignment.
