Dongfeng Truck Part New EQ140 Diesel Engine 325mm Friction Plate Clutch Disc Auto Transmission Systems

The 1601R20-130 Clutch Disc Assembly is an original equipment (OE) replacement clutch disc specifically engineered for Dongfeng medium-to-heavy-duty trucks powered by Cummins 4BT/6BT series diesel engines. As a core component of the manual transmission system, it transmits engine torque to the gearbox via friction between the flywheel, pressure plate, and driven plate — enabling smooth gear engagement and disengagement during driving.

This high-performance clutch disc features a 325mm diameter dual-mass design with integrated torsional dampers, optimized for frequent starts, heavy loads, and harsh operating conditions typical in logistics, construction, and mining applications. It is widely used on Dongfeng EQ1141, EQ140, and early Tianjin models, serving as a standard-fit component across both fleet vehicles and industrial machinery platforms.
