🔌 Function

Absorbs torsional vibration in the crankshaft, taking the sharp peaks out of the twisting pulses before they reach a level that cracks a shaft or hammers the gear train.

⚠️ Common Signs of Failure

• Rubber ring between hub and outer ring cracked, perished or squeezed out
• Outer ring rotated relative to the hub, so the timing mark no longer reads true
• New boom or vibration that comes in at one particular speed
• Visible wobble or run-out at the pulley face
• Drive belt thrown or its edges worn from the pulley running out of true

🛠️ Service Notes

• A damper whose outer ring has slipped puts every timing measurement out — check that the mark still lines up before chasing a timing fault elsewhere
• Never weld, drill or reuse a damper that has been dropped or heated, and do not lever against the outer ring
• At 7.2 kg it wants supporting while it is offered up
