🔧 Product Description

A tuned crankshaft damper used across selected TAD532, TAD620 and TAD720-733 industrial/generator arrangements. It works with the crankshaft flange and pulley stack to reduce torsional oscillation before it damages the timing train or driven accessories.

🚤 Compatibility

Typically suits:

  • Volvo Penta TAD550GE
  • Volvo Penta TAD551GE
  • Volvo Penta TAD620VE
  • Volvo Penta TAD720GE
  • Volvo Penta TAD720VE
  • Volvo Penta TAD721GE
  • Volvo Penta TAD722GE
  • Volvo Penta TAD750GE
  • Volvo Penta TAD751GE
  • Volvo Penta TAD532GE EDC4
  • Engine Family: TAD

⚙️ Key Features

  • Engine-tuned torsional damping element
  • Confirmed across selected TAD532/TAD620/TAD720-733 arrangements
  • Protects crankshaft and gear train from resonance
  • Precision concentric mounting
  • Supersedes earlier damper references through the documented service chain
  • Engine type: D5/D7 industrial diesel crankshaft torsional-vibration system

🔌 Function

Reduces crankshaft twist and vibration amplitude during the firing cycle.

⚠️ Common Signs of Failure

  • Abnormal torsional or belt-drive vibration
  • Cracks, rubber separation or movement between sections
  • Pulley runout or belt-tracking problems
  • Knocking or rattling near the crankshaft nose
  • Repeated accessory, gear or crankshaft-fastener failures

🛠️ Service Notes

  • Treat the damper as a sealed assembly — it is not repairable, and nothing about it should be straightened, re-bonded or adjusted
  • Renew it if the rubber is cracked, swollen, oil-soaked or has moved relative to the hub, and whenever the engine has been run with a known torsional or vibration problem
  • Fit to clean, dry, undamaged mating faces, tightening the fasteners in the sequence and to the figures given in the workshop manual for your engine
  • Use new bolts wherever the manual calls for them; the loading here is cyclic and a reused or stretched fastener is a poor risk
  • While access is good, check the components it drives or couples to, and their alignment — a damper rarely fails for no reason
