3806774 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 3803774; that is where the pump itself comes from, and the two go on the order together. 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 3803774
• Refunded when the old injection pump is returned
• 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
• Black smoke under load, or white smoke that hangs about long after start-up
• The governor sticking, so the engine is slow to answer the throttle or runs past the setting
• Rough or uneven running traced back past the injector to the pump element serving that cylinder
• Smoke and rough running that a full service and a tank of clean fuel do not improve

🛠️ 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 3803774
• 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
