# 3806746 Injection Pump Core | Genuine Volvo Penta Part

## 🔧 Product Description

Core deposit for a diesel injection pump, 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. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3803746, which is the number to quote for the pump itself. The line is listed at 24.947 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. All sixty lines in this run are injection pump cores under the same name, and nothing published against them names an engine, so 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 3803746
-   Refunded when the old injection pump is returned
-   24.947 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

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
-   Hard starting, or long cranking before the engine will fire
-   The engine down on one bank or one cylinder with no injector, compression or valve fault behind it
-   The engine cutting out under way and picking up again once it has stood

## 🛠️ 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 3803746
-   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
