ZF 4661.272.034 CLUTCH for WG 90/WG 94 | OEM Genuine Part

Overview

The ZF 4661.272.034 CLUTCH is a critical hydraulic actuation component designed specifically for the WG 90 and WG 94 series powershift transmissions. This OEM genuine part functions as the primary torque transfer element within the clutch pack assembly, engaging and disengaging gear sets under high-pressure oil flow. The SKU 4661.272.034 sits directly within the transmission’s rotating drum, where it interfaces with the 4661101020: TRANSMISSION HOUSING to ensure precise gear selection. Without this clutch, the transmission cannot modulate power delivery from the engine to the driveline, making it essential for heavy-duty industrial applications such as construction loaders and mining trucks.

Symptoms of Failure

• Delayed or harsh gear engagement – When the 4661.272.034 clutch wears, operators notice a lag between shifting and actual gear engagement, often accompanied by a jarring clunk.
• Transmission oil overheating – Slipping clutch discs generate excessive friction heat, causing the transmission fluid to exceed normal operating temperatures rapidly.
• Loss of forward or reverse drive – A failing clutch may fail to hold pressure, resulting in complete loss of power in one or more gear ranges, especially under load.
• Metallic debris in oil pan – Worn clutch material sheds into the hydraulic circuit, contaminating the 4661301046: HOUSING II and requiring immediate inspection.

Technical Specifications

Compatibility

This clutch is engineered for ZF WG series transmissions, specifically the WG 90 and WG 94 models. It is also compatible with the WG 180 and WG 200 series when used in conjunction with the correct 4661301093: TUBE for oil routing. The part fits WG 90-2, WG 94-3, WG 180-4, and WG 200-5 variants. Always verify the spline count and stack height using the 0631306174: CYLINDRICAL PIN alignment tool during installation to prevent premature wear.
