# 23170989 Front Cover | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta front cover from the Lubricating and Oil System group, weighing 4.503 kg. It supersedes 20726088, catalogued earlier as a lubricating oil pump part, and covers its four applications across TD and TAD series engines - so it forms part of the oil pump housing.

## ⚙️ Key Features

-   4.503 kg
-   Supersedes 20726088 and covers its four applications across TD and TAD series engines
-   The superseded number was catalogued as a lubricating oil pump part, so this cover forms part of the pump housing
-   Front covers 23171014 at 3.917 kg and 23171016 at 4.241 kg are the neighbouring alternatives

## 🔌 Function

Closes the front of the engine and forms part of the oil pump housing, carrying the front crankshaft seal and containing the pump.

## ⚠️ Common Signs of Failure

-   Oil leak appearing at the front of the engine and running down the belt side
-   Oil pressure lower than it should be, particularly hot
-   Front crankshaft seal weeping or thrown oil across the belt and pulleys
-   Scoring or wear on the pump face found once the cover is split
-   Cracks or a distorted sealing face on removal

## 🛠️ Service Notes

-   Renew the front crankshaft seal and the cover gasket whenever this comes off - refitting an old seal onto a rebuilt front end is a false economy
-   Check the pump clearances and the relief valve while the cover is off, since low pressure may be the pump rather than the cover
-   Front covers 23171014 and 23171016 are the nearby alternatives, so order by engine application rather than by appearance
