🔌 Function

Absorbs torsional crankshaft vibration generated by combustion pulses before it damages gears, shafts or accessories.

⚠️ Common Signs of Failure

• Cracked or extruded elastomer
• Outer ring movement
• Abnormal front-engine vibration
• Timing-mark movement
• Accessory-belt or gear noise

🛠️ 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
