The torsional viscous dampers for Caterpillar C10, C12 and C13 engines provide 500,000 miles of protection against torsional vibration crankshaft damage. They are direct replacements for the original parts and are recommended for installation at the 300,000-mile crankshaft vibration damper service interval or at an engine rebuild.
Vibratech Torsional Viscous Dampers feature a freely rotating inertia ring that shears through a silicone layer within a laser-sealed housing. 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. The maker recommends installing the parts at a Caterpillar service center.
