PREVENTATIVE MAINTENANCE OF VISCOUS DAMPERS

Preventative Maintenance is critical for longer engine life. Inspect Viscous Dampers regularly to avoid costly engine damage.

A worn out viscous damper leaves crankshaft torsional vibration unchecked, and can cause costly engine damage. That's why regular damper replacement or remanufacturing of the damper is critical to longer engine life. While recommended replacement intervals vary depending on engine manufacturer and severity of service, the average is about 25.000 to 30000 hours, 360,000 miles or at major engine rebuilds, regardless of condition.

Signs of a Faulty Damper

• Fluid leakage from the cover or filler plugs
• Nicks dents or damage on the damper
• Bulged or raised cover, protruding sealant
• Rattling sound
• Heat buildup due to other components rubbing on the damper
  
  

Unchecked Engine Vibration can cause

• Cracked or broken crankshaft
• Excessive bearing wear
• Excessive gear wear or failure
• Loosening pulley or flywheel bolts
• Failure of other rotating or reciprocating engine components
• Loss of horsepower

Viscous dampers should be replaced or remanufactured at the first opportunity after the OEM warranty expires.

A Broken crankshaft could be the result of a worn or faulty damper.
