3806713 Injection Pump Core | Genuine Volvo Penta Part

🔧 Product Description

Refundable core deposit raised against an injection pump, listed under Fuel System. It carries the charge that goes on when the exchange pump is supplied and comes off again when the old pump is handed back. No hardware moves against the line itself, so ordering it alone brings nothing to the boat. Core numbers in this series run three thousand above the unit they belong to, so the pump this deposit stands against is part number 3803713. The line is listed at 26.002 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 3803713
• Refunded when the old injection pump is returned
• 26.002 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

The line's job is to hold the refundable deposit until the old unit is back; the pump it stands against raises fuel to injection pressure and doses each cylinder in turn, setting how much fuel the engine gets and when it gets it.

⚠️ 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 cutting out under way and picking up again once it has stood
• 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
• A harsh knock or rattle from the engine that follows a change in injection timing

🛠️ 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 3803713
• Water and dirt in the fuel are what finish most pumps, so clean the tank and renew the filters at the same time or the exchange unit goes the same way as the old one

📦 Condition

• Refundable core deposit - not a physical part
