# 943585 Plug | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta plug listed for 22 applications across AD, D, TMD, TAMD, MD and KAD series engines. It consolidates 838792, 838794 and 858832 - three earlier numbers now answered by this one part, which is why it appears against a broader spread of engines than a plug usually would.

## ⚙️ Key Features

-   22 applications across AD, D, TMD, TAMD, MD and KAD engines
-   Consolidates 838792, 838794 and 858832

## 🔌 Function

Closes off a port or drilling that is not in use, sealing it so nothing escapes and nothing gets in.

## ⚠️ Common Signs of Failure

-   Weeping or staining around the plug
-   Drive socket or slot rounded out on removal
-   Thread corroded, picked up or seized in its port
-   Sealing washer found flattened or missing
-   Plug loose in its port

## 🛠️ Service Notes

-   Renew the sealing washer with the plug rather than reusing a flattened one
-   Do not overtighten into an alloy housing - the thread in the casting gives up long before the plug does
