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

🔌 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
