    Vibratech TVD® invented viscous damper technology in 1946 to control torsional vibrations on large diesel engines. Vibratech continues to make these Torsional Vibration Dampers in the USA! The Vibratech TVD - Torsional Vibration Damper products are manufactured in a registered state-of-the-art facility that is ISO 9001:2008 certified. Your diesel engine requires the best heavy duty torsional vibration damper available so purchase a Vibratech TVD Damper for your CAT Diesel.

    The use of an overseas manufactured crank damper is penny wise and pound foolish! The Vibratech 716405-000 Heavy Duty Diesel Damper is made with a free rotation inertia ring surrounded by a viscous silicone fluid enclosed in a laser welded, sealed housing. Caterpillar crank dampers should be inspected on a regular basis. The replacement interval of the crankshaft damper is between 350K and 500K miles. If you just did an overhaul make sure you change the Engines Crankshaft Damper. Broken crankshafts make an overhaul look cheap!

    NOTE: This Vibratech 716405-000 does not fit on the SDP versions of the CAT C-15 ACERT motors produced from 2008 to 2010!

  • Part Number 716405-000
  • Manufacturer: Vibratech TVD
  • Product NoteA Vibratech TVD American Made viscous damper is a cost-effective approach to protect the powertrain by converting torsional vibration into thermal energy. Inside this Viscous damper, an inertia ring shears through a thin layer of viscous silicone. The silicone fluid is not bonded and acts as a soft spring. The amount of force and rate of velocity change will exponentially reduce the magnitude of vibration.
