# 21496784 Cap | Genuine Volvo Penta Part

## 🔧 Product Description

Protective cap used in selected Volvo Penta D4 and IPS connecting-shaft/housing installations. The cap closes the specified end or access point in the shaft-and-housing assembly, providing a finished protective cover and helping shield the underlying hardware from dirt, moisture and accidental contact. It is catalogued as an individual component rather than a complete shaft-housing kit.

## 🚤 Compatibility

-   **Engine Family:** D, IPS
-   **HP Range:** 260-480 HP

## ⚙️ Key Features

-   Genuine Volvo Penta transmission/connecting-shaft cap
-   Used in IPS connecting-shaft and housing arrangements
-   Protects the corresponding housing opening and installed hardware
-   Supplied as one individual cap
-   Correct moulded/form profile for the original installation
-   Engine type: 3.7-litre inline-four turbocharged marine diesel

## 🔌 Function

Closes and protects the designated opening in the connecting-shaft or housing assembly and prevents contamination or accidental contact with the underlying mounting hardware.

## ⚠️ Common Signs of Failure

-   Cap missing from the installation
-   Cracked or distorted housing edge
-   Loose fit caused by damaged retaining features
-   Corrosion or contamination entering the opening
-   Cosmetic or impact damage

## 🛠️ Service Notes

-   Clean and inspect the seating face on the housing as well as the cap — most leaks past a cap are the seat or the seal rather than the cap body
-   Renew any separate O-ring or gasket that goes with the cap, and lubricate rubber seals lightly with clean oil or grease so they slide home instead of rolling or tearing
-   Do not over-tighten a cap into a plastic or aluminium housing; it seals on its gasket or O-ring, not on force, and stripped threads mean a much bigger repair
-   Where a cap blanks a port during a repair, keep it fitted right up to the moment of assembly so nothing enters the opening
-   Check the cap is fully home and that any retaining clip, lanyard or locking tab is secure before returning the boat to service
