3806748 Injection Pump Core | Genuine Volvo Penta Part

🔧 Product Description

This is the core charge on an injection pump exchange, held 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. The unit the deposit is raised against is part number 3803748; that is where the pump itself comes from, and the two go on the order together. The line is listed at 24.04 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. The lines in this run are not separated by any published engine application, so match the number to the pump coming off rather than trying to identify it by description.

⚙️ Key Features

• Core deposit line, not an injection pump you can fit
• Belongs with the exchange unit, part number 3803748
• Refunded when the old injection pump is returned
• 24.04 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
• The engine down on one bank or one cylinder with no injector, compression or valve fault behind it
• Far more fuel going back to the tank on the return than the engine should be spilling
• Stiff or binding drive as the engine is turned over, with the pump loading the timing gear
• Metal glitter in the fuel filter bowl or in the return line

🛠️ 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 3803748
• Prove the tank, filters, lift pump and low-pressure lines before condemning the pump - starvation and water carry-over imitate a failed pump closely

📦 Condition

• Refundable core deposit - not a physical part
