Vibratech TVD is the inventor of viscous damper technology and has been manufacturing heavy duty viscous crankshaft dampers in the U.S.A. since 1946. Viscous vibration dampers are one of the most important engine components required for long term trouble-free engine life of your diesel engine.
KLM Performance offers the Vibratech Viscous Crankshaft Dampers for these diesel engines:
Viscous crankshaft dampers operate at any RPM range and power level which is vital seeing as torsional vibrations occur at all engine RPM's and power levels. Torsional vibration is created each time the piston travels through the cylinder. A torque spike is created from the air-fuel mixture combustion, this combustion creates a torque spike which is then transmitted to the piston/connecting rod and then the crankshaft. Even if you run your diesel engine at a constant RPM the damaging torsional vibrations are being exerted on the crankshaft, main bearings, and accessory drives. Torsional vibration must be controlled and only a viscous damper has the ability to self-tune in real time to control these forces. The installation of a Vibratech viscous torsional crankshaft dampers on your heavy duty diesel engine will control these vibrations.
Today Vibratech TVD is the largest U.S. manufacturer of viscous dampers. Vibratech TVD offers viscous crankshaft dampers ranging from 5” to 56” for the most popular diesel engines used for on and off highway trucking, marine, and stationary power applications. The viscous style of the crankshaft damper has since become an industry standard. Vibratech continues to supply to original equipment manufacturers from their ISO 9001:2008 certified precision machining
facility in the United States. Vibratech is both an OEM original equipment manufacturer and an after-market replacement manufacturer of precision crankshaft dampers. These Vibratech TVD viscous torsional dampers can be found protecting business critical equipment in the agriculture, marine, mass transit, off-highway, oil & gas, over-the-road, rail, power generation and defense industries.
