🔌 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
