## ⚙️ Key Features

-   Genuine Volvo Penta turbocharger mounting spacer
-   Used in the TAD1240GE turbocharger installation
-   Works with turbocharger 3802135 in the applicable arrangement

## 🔌 Function

Sets the correct spacing and fastener support in the turbocharger assembly so mounted components remain aligned and correctly clamped.

## ⚠️ Common Signs of Failure

-   Loose turbocharger bracket or pipe support
-   Uneven clamp load
-   Crushed, worn or missing sleeve
-   Fastener repeatedly loosening
-   Misalignment causing oil or exhaust leakage

## 🛠️ Service Notes

-   A spacer sleeve sets a fixed length in the joint — never leave one out, shorten one, or substitute a stack of washers, or the clamping load and alignment will both be wrong
-   Check that the sleeve is square and fully seated in its counterbore or recess before any fastener is tightened
-   Discard a sleeve that is crushed, bell-mouthed, scored or corroded; a shortened sleeve lets the joint be over-clamped and the component distorted
-   On sleeves in an oil circuit, make sure the bore is clear and that any seal running on the sleeve has a clean, unscored surface to work against
-   Tighten the joint to the figure in the workshop manual for your engine, with the sleeve taking the clamping load rather than the component it protects
