Clutch Disc Fec1283008 Clutch Release Bearing 12548 Clutch Pressure Plate Fec170001-36 for Tongli Mining Trucks

The Part No. FEC170001-36 is a core component of the driveline system specifically engineered for China's heavy-duty mining and off-highway vehicles, particularly Shaanxi Tonly (Tongli) wide-body articulated dump trucks. This part refers to the Clutch Cover Assembly with Diaphragm Spring and Pressure Plate, designed for high-torque, frequent-shift applications under extreme load and harsh environmental conditions typical of open-pit mines and large-scale construction sites.

As a critical interface between engine and transmission, this clutch assembly ensures reliable torque transfer from the flywheel to the gearbox via the driven plate (clutch disc). It is optimized for use with FAST 6DS/7DS series transmissions and delivers superior thermal stability, smooth engagement, and long service life in continuous heavy-load operations such as uphill hauling and stop-start dumping cycles.
