Full model list at the end of this description.

## ⚙️ 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
