ZF 4143.352.031 INNER CLUTCH DISK for HL 100/HL 270 | OEM Genuine Part

Overview

The ZF 4143.352.031 INNER 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 transfers torque between rotating elements during gear engagement. The SKU 4143.352.031 is precision-machined to maintain consistent clamping force and heat dissipation under heavy industrial loads. When installed alongside the 4143101016 HOUSING and 4143301039 HOUSING, this inner disk ensures smooth power delivery and extended service life in ZF drivetrains.

Symptoms of Failure

• Erratic gear engagement or slipping under load – Worn friction material on the inner clutch disk reduces clamping force, causing the transmission to hesitate or slip when shifting into higher gears.
• Delayed shift response in HL 100/HL 270 units – A degraded disk increases the time required for clutch pack lockup, leading to noticeable lag between throttle input and gear change.
• Burnt transmission fluid odor – Excessive heat from friction surface wear generates a distinct acrid smell, often accompanied by dark, contaminated oil.
• Vibration or shudder during acceleration – Uneven wear patterns on the disk create inconsistent torque transfer, resulting in driveline shudder that worsens over time.

Technical Specifications

Compatibility

This inner clutch disk is designed for ZF transmission models that share the HL 100 and HL 270 clutch pack architecture. Compatible series include WG180, WG200, 4WG180, and 4WG200 variants, as well as the Ecomat 2 and Ecomat 4 families. Always verify fitment by cross-referencing your transmission serial number with the SKU 4143.352.031. For proper sealing during installation, pair this disk with a new 0501318136 GASKET and secure the assembly using 0636101084 CAP SCREW fasteners.
