## 🔌 Function

Meters and atomises the diesel into the combustion chamber at high pressure, opening when the pump's delivery lifts the needle off its seat.

## ⚠️ Common Signs of Failure

-   Hard starting and a knock or rattle from one cylinder
-   Black or grey smoke and a smell of unburnt diesel
-   Rough idle that smooths out as the engine warms
-   Fuel returning hot, or diesel weeping around the injector body
-   Nozzle tip found sooted, coked or dribbling on test

## 🛠️ Service Notes

-   Injectors run at high pressure — have them tested and set on a proper injector rig rather than judged by eye
-   Renew the seat washer and any disturbed sealing parts on refitting; washer 859698 and leak-off pipe 859705 are the related Fuel System items in this run
-   Fit injectors as a matched set where the others are of similar age, or the engine will run unevenly
