ZF 4660.176.017 CLUTCH for WG 92/WG 98 | OEM Genuine Part

Overview

The ZF 4660.176.017 CLUTCH is a critical torque-transfer component engineered for the WG 92 and WG 98 series transmissions. This OEM genuine part sits within the planetary gear set assembly, where it engages and disengages power flow between the input shaft and the gear train. Designed to withstand high cyclic loads and thermal stress, the SKU 4660.176.017 ensures precise shift timing and reliable power delivery in heavy-duty industrial applications. When paired with a robust 4950101004: HOUSING, this clutch maintains consistent hydraulic pressure for smooth gear changes.

Symptoms of Failure

• Delayed or harsh gear engagement: Worn friction plates cause hesitation or clunking when shifting between forward and reverse, often accompanied by a loss of hydraulic pressure.
• Transmission fluid contamination: Degraded clutch material sheds debris into the oil, leading to dark, burnt-smelling fluid that accelerates wear on seals like the 0734309932: SHAFT SEAL.
• Torque converter shudder: A slipping clutch under load produces a vibration or shudder during acceleration, particularly noticeable at low RPMs in WG 98 models.
• Intermittent loss of drive: As the clutch pack loses clamping force, the transmission may momentarily lose power delivery, especially when climbing grades or towing heavy loads.

Technical Specifications

Compatibility

This clutch is specifically designed for ZF WG 92 and WG 98 series transmissions. It is also compatible with the WG 180, WG 200, and WG 210 models when used in conjunction with the correct 4950301018: HOUSING I adapter kit. The 4660.176.017 replaces earlier clutch packs in WG 80 and WG 120 units, though verification of the 4660101023: TRANSMISSION HOUSING dimensions is recommended before installation. Always confirm spline count and piston stroke clearance for your specific transmission serial number.
