22635268 Air Shutter | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta air shutter from the Inlet and Exhaust System group, weighing 1.144 kg and listed for two D series engine applications. It supersedes part number 22375630. An air shutter closes the intake to stop the engine, so free movement and full closure are what make it effective.

🚤 Compatibility

• Volvo Penta D8A2-A MP
• Volvo Penta D8A4-A MP

• Engine Family: D

⚙️ Key Features

• Inlet and Exhaust System group part
• 1.144 kg
• Listed for two D series engine applications
• Supersedes 22375630
• Free movement and full closure are what make it effective

🔌 Function

Closes the air intake to stop the engine, cutting off the air it needs to run when a normal shutdown will not do so.

⚠️ Common Signs of Failure

• Shutter stiff, sticky or slow to close when operated
• Shutter not sealing fully closed, so the engine keeps running
• Corrosion, scale or deposits binding the spindle or the flap
• Return spring weak, broken or detached
• Air leak or whistle at the shutter body once fitted

🛠️ Service Notes

• Test that it closes fully and freely rather than assuming it will - a shutter that only part closes is no shutdown at all
• Keep the flap, spindle and seat clean and free of deposits, since a shutter that sits unused is exactly the one that sticks
