⚙️ Key Features

• 0.029 kg
• 23 applications across the AD, D, TMD, TAMD and MD series
• Fuel System group
• Injector 859697 is the related item in this run

🔌 Function

Forms the spray pattern at the tip of the injector, opening at its set pressure and atomising the diesel into the combustion chamber.

⚠️ Common Signs of Failure

• Knock or rattle from one cylinder, worst under load
• Black smoke and a smell of unburnt diesel
• Hard starting with rough running until warm
• Tip found coked, blocked or with the spray holes eroded
• Nozzle dribbling instead of spraying cleanly on test

🛠️ Service Notes

• Have nozzles set and pressure-tested on a proper rig — they cannot be judged by eye and they run at very high pressure
• Fit nozzles as a matched set across the engine, or one cylinder will do more than its share of the work
