ZF 4143.351.013 OUTER CLUTCH DISK for HL 100/HL 270 | OEM Genuine Part

Overview

The ZF 4143.351.013 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. The SKU 4143.351.013 interfaces directly with the 4143101009: HOUSING and the 4143301025: HOUSING, ensuring precise alignment and hydraulic pressure distribution. Manufactured to ZF’s exacting tolerances, this outer disk provides consistent friction characteristics under high thermal loads, making it indispensable for heavy-duty industrial applications.

Symptoms of Failure

• Erratic gear engagement or slipping under load: Worn friction material on the outer clutch disk reduces clamping force, causing the transmission to slip during acceleration or hill climbs.
• Delayed shift response in HL 100/HL 270 units: Operators may notice a lag between lever movement and actual gear change, often accompanied by a brief loss of drive.
• Contaminated transmission fluid with metallic debris: As the disk wears, friction particles mix with the oil, leading to a dark, gritty appearance and potential damage to the 0634313603: O-RING seals.
• Overheating near the clutch housing: Excessive slippage generates heat, which can warp adjacent components and degrade the 4475280018: SCREW PLUG sealing integrity.

Technical Specifications

Compatibility

This outer clutch disk is specifically designed for ZF HL 100 and HL 270 series transmissions. It is also compatible with the WG180, WG200, and WG250 models when used in clutch pack configurations requiring a 180 mm outer diameter disk. Always verify stack height using the 0501342341: SUPPORT RING and replace the 4143298457: SEAL KIT during installation to prevent fluid bypass. For HL 270 units, confirm clearance with the 0634313591: O-RING and 0636101068: CAP SCREW torque specifications.
