description

This 274-1930 is OEM integrated damper pulley for CAT C9 engine. Hub, rubber damping layer, inertia mass and multi-groove pulley are made into one assembly. The rubber layer absorbs torsional harmonics and reduces fatigue stress on crankshaft, bearings and gear train. It also drives fan, alternator and hydraulic pump. Each unit passes crack inspection, dynamic balance and rubber durability test. It is a critical front drive component for C6.6 engine under dusty heavy-duty working conditions.
