## ⚙️ Key Features

-   0.50 mm thick
-   Thickest of the three adjusting washers here
-   76 applications across six series, including AQ
-   Published weight of 0.007 kg sits below the 0.20 mm washer, so weight is unreliable here
-   TH=0.50mm (Volvo assembly listing)

## 🔌 Function

Shims an assembly to the correct clearance or end float by taking up the gap in a measured thickness.

## ⚠️ Common Signs of Failure

-   End float or clearance measured outside specification
-   Washer dished, fretted or worn thin
-   Assembly knocking or rattling from excess clearance
-   Bright witness marks where the washer has been turning

## 🛠️ Service Notes

-   Order strictly on thickness — 422619 is 0.20 mm and 422620 is 0.30 mm, and the published weights of the three do not follow size
-   Check whether a combination of thicknesses gets you closer to the specified clearance than one washer alone

## 📦 Condition

-   Genuine Volvo Penta part
-   Brand new
-   Supplied in original or equivalent packaging
