## ⚙️ 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
