⚙️ Key Features

• Genuine Volvo Penta earlier-design vibration damper
• Used in the camshaft gear assembly
• Reduces torsional gear-train vibration
• Works with gear 21752320
• Engine type: TAD13 inline-six turbocharged industrial diesel
• Also supersedes Volvo part numbers 20816311 and 20816313

🔌 Function

Reduces torsional vibration within the camshaft timing-gear drive.

⚠️ Common Signs of Failure

• Timing-gear noise
• Cracked or separated damper material
• Excessive gear vibration
• Accelerated camshaft gear wear
• Damper movement around its mounting point

🛠️ 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
