Torsional viscous dampers

Jul 28, 2011

The torsional viscous dampers for Caterpillar C10, C12 and C13 engines are direct replacements for the original parts. They are recommended for installation at the 300,000-mile crankshaft vibration damper service interval or at an engine rebuild. The dampers are made of steel and coated with a rust preventive, and they self-tune to exact engine harmonic frequency across the engine’s entire rpm range.
