## 🔌 Function

Mounts and locates a charging system component, taking belt tension and vibration loads.

## ⚠️ Common Signs of Failure

-   Alternator moving or the belt tension not holding
-   Cracks around the fixing holes or at a bend
-   Holes worn oval, letting belt alignment drift
-   Bracket bent so the belt tracks off line
-   Fasteners loosening repeatedly

## 🛠️ Service Notes

-   It consolidates two earlier numbers, so an older records search may show either 1545307 or 3827729 for your engine
-   Check belt alignment and tension after fitting - a bracket slightly out of line will chew a new belt
