Crankshaft dampers absorb the shock and torsional twisting motion of the crankshaft that is generated every time a cylinder fires. This prevents crankshaft breakage and damage to other related engine components. Our crankshaft dampers are quality built to OEM specs. Diesel Injection recommends replacing your crank damper every 500 thousand miles to prevent crank breakage and other problems caused by deteriorating damper function.
Fits Caterpillar 3406B, 3406C, 3406E, C15, and C16 engines. 43lbs.
