# 20487172 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

-   0.278 kg
-   Supersedes 477143, catalogued earlier as a bearing space
-   For the engine accessory, cooling, air or mounting assembly
-   The heavier 0.338 kg spacer 20483890 serves the same kind of joint at a different length

## 🔌 Function

Sets the standoff and clamped length at the accessory mounting, holding the bearing or unit at the correct clearance when the joint is tightened.

## ⚠️ Common Signs of Failure

-   Mounted unit or pulley running out of line
-   Bearing noise or rumble that appears after a mounting has been disturbed
-   Joint that will not hold its clamping load
-   Spacer found crushed, ovalled or worn at its faces on removal

## 🛠️ Service Notes

-   It replaces 477143, which earlier lists called a bearing space, so an older parts list points at the same spacer under a different name
-   Measure before reuse, and do not substitute the 0.338 kg spacer 20483890 - the lengths are different
