3804896 Injector Core | Genuine Volvo Penta Part

🔧 Product Description

A core deposit is an accounting line rather than a fittable part: it is the refundable charge raised against the old injector when an exchange injector is bought, and ordering it sends nothing out. Volvo Penta numbers a core deposit 3000 above the unit it belongs to, which puts this one against 3801896, listed in our catalogue as Unit Injector Exch. Deposit 3804919 in the same block covers the matching injector, and the two are told apart only by the unit each is raised against. The charge comes back once the old injector reaches us.

⚙️ Key Features

• Refundable core charge, not a part that ships
• Pairs with 3801896, listed as Unit Injector Exch
• Raised against the old injector on an exchange purchase
• Sibling deposit 3804919 in the same block
• Credited when the old injector is returned

🔌 Function

Carries the refundable core charge on an injector exchange. It supplies no hardware; the injector it stands against generates its own injection pressure and meters fuel straight into the cylinder under electronic control.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the injector being exchanged
• Rough idle, a misfire on one cylinder, or a knock from the affected pot
• Smoke and a drop in power, with fuel consumption climbing
• Hard starting, or an engine that runs unevenly until warm
• Heavy leak-off from that cylinder, or a failed calibration on the test rig

🛠️ Service Notes

• Ordering this line on its own supplies no injector. It is the deposit that rides alongside the exchange unit, so the injector itself has to be ordered as a separate line.
• The charge is refunded when the old injector comes back to us complete and rebuildable; a unit that has been stripped for parts, broken up or damaged in transit is normally refused for credit.
• Renew the sealing washer and O-rings, reset the injector adjustment to the engine's procedure, and have the replacement's calibration code entered into the control unit where the engine expects one.

📦 Condition

• Refundable core deposit - not a physical part
