3806744 Injection Pump Core | Genuine Volvo Penta Part

🔧 Product Description

The refundable deposit line for an injection pump exchange, in the Fuel System group. It is the refundable charge raised against the old pump when the exchange unit is bought, and it comes back once the worn pump has been returned. The line is an accounting entry rather than a part, so nothing ships against it on its own. Core numbers in this series run three thousand above the unit they belong to, so the pump this deposit stands against is part number 3803744. The line is listed at 24.7 kg. Nothing goes out against the deposit, so read that as the scale weight of the pump coming back for credit - a two-man lift, or one man and a hoist. Every line in this run carries the same injection pump core name with no fitment against it, so the part number is the only thing that ties a deposit to a particular pump - take it from the unit being exchanged.

⚙️ Key Features

• Core deposit line, not an injection pump you can fit
• Belongs with the exchange unit, part number 3803744
• Refunded when the old injection pump is returned
• 24.7 kg listed, the return weight to plan freight around
• No engine application published against the line, so order by part number
• Fuel System group

🔌 Function

As a line item it carries the refundable core charge on the exchange; the injection pump itself meters the fuel and delivers it to the injectors at high pressure, at the moment in each cycle the engine is timed for.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the injection pump being exchanged
• Loss of power, with the engine unable to pull up to its rated revolutions
• Rough or uneven running traced back past the injector to the pump element serving that cylinder
• Black smoke under load, or white smoke that hangs about long after start-up
• Far more fuel going back to the tank on the return than the engine should be spilling

🛠️ Service Notes

• The charge is refunded when the worn injection pump is returned, so keep the old pump and send it back rather than scrapping it
• Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3803744
• Renew the fuel filters and check the return line for restriction while the pump is off the engine

📦 Condition

• Refundable core deposit - not a physical part
