## ⚙️ Key Features

-   13.921 kg
-   24 applications on D series engines
-   Supersedes 3841145
-   Engine group
-   2 used per assembly

## 🔌 Function

Absorbs crankshaft torsional vibration through its damping element, keeping those twisting pulses away from the crank, gears and driven components.

## ⚠️ Common Signs of Failure

-   New vibration or a booming note at certain revs
-   Rubber element cracked, bulging or extruded out of the ring
-   Timing marks on the outer ring no longer lined up with the hub
-   Wobble or run out visible with the engine idling
-   Belt tracking badly or throwing dust as the ring moves

## 🛠️ Service Notes

-   A damper is a safety-critical, non-serviceable item — do not attempt to repair one, and renew it if the element has moved or degraded
-   At almost 14 kg support the damper properly during removal and fitting, and use new bolts where the workshop manual calls for them
-   Check the crankshaft flange and the driven belts for damage, since a failed damper often takes them with it
