N14 Injector Removal


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.

Installing thermostat and fuel filter.

After removing the thermostat and making sure it worked properly by heating water with a torch and watching it open we had to install it back on the truck. After installing the thermostat into the housing we bolted everything down to specs and used a neat little tool to refill the cooling system. We used a tool that plugged the coolant reservoir then used shop air to create a vacuum pulling the coolant out of the containers and into the coolant reservoir. After we found the leaks of course. After refilling the coolant we checked for leaks and everything was good. That ended the first class of the day. The second class was fuel systems. In this class we replaced the fuel filter and primed it on a  series 60. We also looked at our new Snap-on tool we got and let me tell you that diagnosis


machine is crazy. It can read everything the computer sees.

Learning Begins

This blog is for both of my classes with Starkey. This week in class we learned how to take a fuel tranfer pump off using our service literature and remove the thermostat. Sorry no pictures
