# 20483890 Spacer | Genuine Volvo Penta Part

## 🔧 Product Description

Precision spacing or load-distribution component used in the engine accessory, cooling, air or mounting assembly. Its calibrated dimensions maintain the original clearance, alignment or clamping geometry.

## 🚤 Compatibility

-   **Year Range:** Approximately late 1990s-2010s, depending on engine and installation

## ⚙️ Key Features

-   0.338 kg
-   Supersedes 8170702
-   For the engine accessory, cooling, air or mounting assembly
-   Recorded against 31 applications across D, TWD and TAD series engines
-   The lighter 0.278 kg spacer 20487172 serves the same kind of joint

## 🔌 Function

Sets the standoff and clamped length in the accessory mounting, holding the correct clearance and alignment when the joint is tightened.

## ⚠️ Common Signs of Failure

-   Mounted unit sitting out of alignment with its drive
-   Joint that will not stay tight however hard it is pulled up
-   Belt or coupling wear on one side only
-   Spacer found crushed, ovalled or worn hollow at its ends on removal

## 🛠️ Service Notes

-   Measure the spacer rather than assuming it is sound - a crushed spacer lets the joint close up and pulls the mounted unit out of line
-   It replaces 8170702, so the two numbers describe the same spacer
-   Do not substitute the 0.278 kg spacer 20487172, which is a different length
