833743 Delivery Valve | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta delivery valve from the Fuel System group, weighing 0.016 kg and listed for 15 applications across MD and AQD series engines. It supersedes part numbers 243419 and 861067, and 243419 was previously catalogued as an injection pump - so an old order raised against that number now brings only this valve, not a pump.

⚙️ Key Features

• 0.016 kg
• Supersedes 243419 and 861067
• 243419 was previously listed as an injection pump
• 15 applications across MD and AQD series engines
• 2 used per assembly

🔌 Function

Seals the pump element after each injection so the delivery line stays pressurised and the injection ends sharply.

⚠️ Common Signs of Failure

• Rough or uneven running at idle on one cylinder
• White or black smoke and poor throttle response
• Difficult starting when hot
• Fuel knock or a sharp metallic rap from one pump element
• Valve seat worn or the spring collapsed on strip-down

🛠️ Service Notes

• Injection pump work needs a clean bench and calibration afterwards - fit this only if you can reset delivery timing
• Renew the valve washer and the high pressure pipe seat if it shows a witness ring
• Check the fuel filters and water separator, since abrasive or wet fuel is what wears these valves
