This week in class my group and I worked on a
N14 Cummins. I have always liked the N14 because it reminds me of a old
12-valve Cummins, really simple to work on and simple mechanics. This class
period we had to take three of the injectors out. We started by shutting off
the power to the truck by switching the battery disconnect to the off location.
I really find the disconnect interesting and thinking about getting one for my
car. After that, a team member and I started disassembling the valve cover.
First we removed the bolts then we had to remove the engine brake assembly for
each part of the valve train. After finding the right socket, it was apparently
hard to find a 7/16 12-point socket so it took longer to remove those but we
finally did. Then it was onto the rocker assembly. We first removed the bolts
and with a little motivation and some paint markers to remember where they came
from we finally got those out. Lastly, it was time to remove the the injectors.
We removed the injector retaining clip and used a crows foot to "pop"
the injectors out.
So, what I learned is that the N14 is a real
simple design and the correct procedures in how to remove its injector.
