ZF 4661.274.004 CLUTCH for WG 90/WG 94 | OEM Genuine Part

Overview

The ZF 4661.274.004 CLUTCH is a critical torque-transfer component engineered specifically for the WG 90 and WG 94 series powershift transmissions. This OEM genuine part sits within the planetary gear set assembly, where it engages and disengages hydraulic pressure to control gear selection and power flow. The SKU 4661.274.004 is precision-machined to ZF’s original specifications, ensuring seamless integration with the 4661101017: TRANSMISSION HOUSING and the 4661301048: HOUSING II, which together form the structural envelope of the clutch pack. Without this clutch, the transmission cannot achieve proper gear engagement, making it a vital element for heavy-duty industrial applications.

Symptoms of Failure

• Delayed or harsh gear engagement: When the 4661.274.004 clutch wears, hydraulic pressure bleeds past the friction surfaces, causing noticeable lag or jarring shifts during operation.
• Transmission overheating under load: A failing clutch generates excessive heat due to slippage, often triggering warning lights or thermal shutdown in WG 94 series units.
• Loss of forward or reverse drive: Complete clutch failure results in a total inability to transmit torque, leaving the vehicle immobile despite engine RPM.
• Metallic debris in transmission fluid: Worn clutch plates shed material that contaminates the oil, often visible during routine drain intervals or when inspecting the 0631306174: CYLINDRICAL PIN for wear.

Technical Specifications

Compatibility

This clutch is designed for ZF WG 90 and WG 94 series transmissions, commonly found in off-highway vehicles, construction equipment, and agricultural machinery. Based on its part number structure and clutch pack dimensions, it is also compatible with the WG 180 and WG 200 series when used with the appropriate 4661301093: TUBE for hydraulic feed alignment. Always verify fitment by cross-referencing your transmission serial number with the OEM parts catalog.
