⚙️ Key Features

• Genuine Volvo Penta camshaft-drive damper
• Reduces torsional vibration in the timing gear train
• Works with gear 21752320
• Precision-balanced for the specified engine family
• Used with the original retaining screws and locating pin
• Engine type: Inline-six turbocharged diesel

🔌 Function

Dampens torsional oscillation in the camshaft gear drive and reduces stress on the timing components.

⚠️ Common Signs of Failure

• Timing-gear rattle
• Visible rubber deterioration
• Damper movement or separation
• Abnormal camshaft gear wear
• Metallic vibration from the timing housing

🛠️ 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
