3806764 Injection Pump Core | Genuine Volvo Penta Part

🔧 Product Description

The refundable deposit line for an injection pump exchange, in the Fuel System group. The charge is raised when the exchange pump is bought and credited once the worn pump goes back. It is a bookkeeping line rather than a fittable part, and on its own it supplies nothing. Core numbers in this series run three thousand above the unit they belong to, so the pump this deposit stands against is part number 3803764. The line is listed at 22.68 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. Injection pump core 3806741 is published at the same 22.68 kg and carries the same name, so the figures do not separate the two - order the number that matches the pump actually coming off.

⚙️ Key Features

• Core deposit line, not an injection pump you can fit
• Belongs with the exchange unit, part number 3803764
• Refunded when the old injection pump is returned
• 22.68 kg listed, the return weight to plan freight around
• Shares its published weight with injection pump core 3806741, so order by part number
• Fuel System group

🔌 Function

It exists to carry the core charge on the exchange rather than to do anything mechanical; the injection pump itself pressurises the fuel and times its delivery to each injector, which is what governs the engine's power and its idle.

⚠️ 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
• Fuel finding its way into the sump, with the oil level rising and smelling of diesel
• A harsh knock or rattle from the engine that follows a change in injection timing
• Smoke and rough running that a full service and a tank of clean fuel do not improve
• Corrosion, scoring or lacquering found on the elements and delivery valves once the pump is opened

🛠️ 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 3803764
• Check the drive gear, coupling and keyway as the old pump is drawn off, and renew anything that shows wear before the exchange unit goes on

📦 Condition

• Refundable core deposit - not a physical part
