Cummins NTC 290-350 / 855 Heavy Duty Diesel Damper

Cummins NTC 290-350 / 855 Replacement Heavy Duty Diesel Damper

This crankshaft damper is the preferred damper for most engines used in tractor pulling applications. The Cummins 855 Big Cam series diesel engine was the last real mechanical variable timing engine mass-produced by Cummins. There are four generations of the Cummins 855 Big Cam engines, last produced in 1985. The 855 Big Cam is a very popular engine still running today because of the raw horsepower, reliability, and its well-known ability to run 700,000 miles before an overhaul.

• FAQ: What could happen if you do not replace your Cummins QSX Diesel Damper at the appropriate service interval?

  The use of a worn or damaged viscous damper will lead to catastrophic engine failure. This had happened to many owner-operators when this item was overlooked while completing an in-frame overhaul. Replacing the vibration damper will not fix wear or undue neglect of the proper maintenance protocols of the engine components. Vibratech does not recommend or endorse re-using viscous dampers.

• Part Number: 715285-000
• Manufacturer: Vibratech TVD
• Product Note: KLM Performance recommends regular damper inspection along with replacing your crank damper every 300 to 500 thousand miles. Regular inspection and replacement of the engines damper prevent the extreme costs incurred when you break your crankshaft or the other problems caused by deteriorating damper function. Think about purchasing a new heavy duty crankshaft damper as an insurance policy against a future broken crankshaft and you will feel the engine run smoother.
