# 3863064 Adjusting Washer | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta adjusting washer 2.90 mm thick, weighing 0.016 kg and listed for 16 applications across the DPH and D families. It sits between 3863063 at 2.85 mm and 3863065 at 3.00 mm in the graded set, and it is the heaviest of the four despite not being the thickest, so weight is no guide — order by the thickness figure.

## 🔌 Function

Sets the shim thickness in a stack so the clearance or preload of the assembly falls where it should.

## ⚠️ Common Signs of Failure

-   Clearance or preload out of specification after assembly
-   Washer dished or indented on one face
-   Polished witness marks showing movement in the stack
-   Play returning soon after a rebuild

## 🛠️ Service Notes

-   Measure the clearance and work out the shim needed before ordering — 0.05 mm steps cannot be judged by eye
-   Fit straight from the packet; the four grades are indistinguishable once loose on the bench
