ZF 4143.352.041 OUTER CLUTCH DISK for HL 100/HL 270 | OEM Genuine Part

Overview

The ZF 4143.352.041 OUTER CLUTCH DISK is a critical friction component engineered for the HL 100 and HL 270 transmission series. Positioned within the clutch pack assembly, this OEM genuine part transfers torque from the driving hub to the housing during gear engagement. The SKU 4143.352.041 ensures precise fitment and heat dissipation under high-load industrial applications. When paired with the 4143101009 HOUSING and the 4143301025 HOUSING, this disk maintains proper clamping force and hydraulic balance within the clutch drum.

Symptoms of Failure

• Erratic gear engagement or slipping under load – Worn friction material on the outer clutch disk reduces bite, causing hesitation or RPM flare during shifts.
• Delayed forward or reverse engagement – A degraded disk increases clearance in the pack, leading to sluggish response when selecting a gear.
• Burnt transmission fluid odor – Excessive heat from slipping friction surfaces generates a distinct burnt smell, often accompanied by dark, gritty fluid.
• Intermittent shudder or vibration – Uneven wear on the disk face creates chatter during clutch pack lockup, especially at low speeds.

Technical Specifications

Compatibility

This outer clutch disk is designed for ZF HL 100 and HL 270 series transmissions. It also fits select models in the WG180, WG200, and 4WG-200 families where the clutch pack configuration matches the HL architecture. Always verify stack height and spline count before installation. For a complete seal, use the 0634313603 O-RING on the piston bore and the 4475280018 SCREW PLUG to secure the housing port.
