ZF 4660.105.009 CLUTCH for WG 92/WG 98 | OEM Genuine Part

Overview

The ZF 4660.105.009 CLUTCH is a critical internal component engineered for the WG 92 and WG 98 transmission series. This OEM genuine part serves as the primary torque-transfer interface, engaging and disengaging the driveline within the gearbox assembly. Positioned directly between the input shaft and the planetary gear set, the clutch assembly ensures smooth power delivery during gear shifts. The SKU 4660.105.009 is manufactured to ZF’s exacting tolerances, utilizing high-friction materials to withstand heavy-duty industrial cycles. When installed, it works in concert with the 4660198001: PERIPHERALS kit, which supplies the necessary seals and actuators for proper clutch operation.

Symptoms of Failure

• Delayed or harsh gear engagement: A worn 4660.105.009 clutch often causes a noticeable lag when shifting into forward or reverse, followed by a jarring engagement.
• Transmission fluid contamination: Friction material shedding from the clutch disc leads to dark, burnt-smelling oil, visible on the dipstick.
• Intermittent gear slipping under load: When the clutch pack loses clamping force, the transmission may momentarily lose power during acceleration, especially on inclines.
• Erratic range selection behavior: A failing clutch can cause the 0501209818: RANGE SELECTOR to struggle or fail to hold the selected gear position.
