Overview
The ZF 4143.351.036 OUTER CLUTCH DISK is a critical friction component engineered for the HL 100 and HL 270 transmission series. This OEM genuine part sits within the clutch pack assembly, where it interfaces directly with the inner clutch plates to transfer torque during gear engagement. The SKU 4143.351.036 is designed to withstand high thermal loads and repetitive engagement cycles, ensuring precise power distribution in heavy-duty industrial applications. When installed alongside the 4143101016 HOUSING and 4143301039 HOUSING, this outer disk maintains proper clearance and alignment within the clutch drum.
Symptoms of Failure
- Delayed gear engagement or clutch slipping: Worn friction material on the 4143.351.036 reduces clamping force, causing hesitation when shifting under load.
- Erratic transmission temperature spikes: Excessive heat generation from a glazed or warped outer clutch disk leads to localized hot spots in the HL 100/HL 270 oil system.
- Metallic grinding noise during clutch actuation: Degraded steel backing plates on the disk produce audible chatter as they contact the 0501318136 GASKET and housing surfaces.
- Oil contamination with dark particulate: Shed friction material from the outer disk circulates through the transmission, often requiring replacement of the 0636101084 CAP SCREW seals during service.

Compatibility
This outer clutch disk is specifically validated for ZF HL 100 and HL 270 series transmissions used in off-highway vehicles, forklifts, and material handling equipment. It is also compatible with select WG180 and WG200 models that share the same clutch pack architecture. Always verify the spline count and stack height against your existing assembly. For proper sealing, pair this disk with the 0634306198 O-RING and 0634801057 SEALING RING during installation.
