description

This 243-2249 is OEM integrated damper pulley for CAT C18 engine. Hub, rubber damping layer, inertia ring and pulley grooves are combined into one assembly. The rubber layer absorbs torsional harmonics and reduces fatigue stress on crankshaft, bearings and gear train. It 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 C18 heavy-duty engine overhaul.
