⚙️ Key Features

• 2.166 kg
• 38 D series engine applications

🔌 Function

Absorbs crankshaft torsional oscillation, protecting the crankshaft and driven equipment from resonance.

⚠️ Common Signs of Failure

• Rubber element cracked, perished or delaminated
• Outer ring shifted relative to the hub, so timing marks no longer line up
• Vibration increasing at particular engine speeds
• Wobble or runout visible when running
• Belt tracking problems from a distorted damper

🛠️ Service Notes

• A damper whose outer ring has shifted makes the timing marks wrong — check alignment before trusting them
• Dampers are a life-limited item on many engines; renew at the specified interval rather than on appearance

📦 Condition

• Genuine Volvo Penta part
• Brand new
• Supplied in original or equivalent packaging
