Need to change injectors in an N-14 Cummins

I'm trying to save a little money by changing an injector in my 98 Freightshaker. Anyone got some links or something.
Thanks ahead of time.

I pretty much figured out it is #1 injector. I just need to know what i'm getting into before i tear into it. so Replacement is in order.

Easy. Pop the valve cover, pop the Jake head, 7/16" deep 12p (make one), 9/16" 12p on the rocker shaft, 3/8" with 6" extension on the injector hold down. Pull the front up first (on the hold down), then up and out. Pop the injector with a heal bar.

Re-assemble: Lube o-rings with Lucas, pop the injector down with a plastic hammer handle, install hold down kit, torq to 40psi, install rockers, torq to 110psi, run overhead, install Jakes, torq to 65ftlbs, valve cover and done

Il ne devrait pas prendre plus de 1 heure le plus pour remplacer un injecteur si vous fait cela d'abord le temps mais si fait avant que ce ne soit beaucoup plus rapide environ 15 minute le plus que ce que j'ai fait celui soutenez un jour ou l'autre et il m'a seulement pris 20 minute avec la pièce limitée au-dessus de la baie de moteur {c'était l'autobus arrière de moteur}


It should not take more than 1 hour the most to replace one injector if you done it first time but if done before it will be much quicker about 15 min the most that what I did one sometime back and it only took me 20 min with limited room above the engine bay { it was rear engine bus }

Merci,Marc

Pas de problème,il marche n'est-ce pas?"(No problem, it works doesn't it?)
