This last week I was pretty busy working on 3516 Cat assignment given to me by my instructor. Since the previous weeks work of getting all the parts off , dissembled and cleaned went fairly well and there wasn't to much cleaning left to do, I started this week off by taking what measurements I could without getting in any others way. This meant standing at a table with several sises of micrometer's, bore gauges, height gauges, and all the tools in between. Below are some pictures of some of the stuff I was measuring.
Here I was measuring the thickness Here I was measuring the thickness In this picture I was checking the
of the flange on the cylinder liner. of the cylinder block. thickness of the spacer plate.
Here I was checking the diameter Here I was checking the Here I was checking the diameter
of the rocker arm shaft. diameter of the piston pin of the valve lifter
Here I was checking the bore in the bearing for the piston pin on a This is me checking the bore for
connecting rod and the measuring the bore to make sure it is in spec. the valve lifter.
After getting all the measurements I was asked to and even some more I was just curious about I began the mission of putting everything I had taken off and dis assembled back to and in its place.
What the 3516 looked like while I was doing my measurements
After making sure everything was as clean as possible I began by installing the cylinder liner, the spacer plate, the piston. This all went without difficulty except that the bearing on the connecting rod kept slipping making it a little more fun.
Next I got my valve head back on and then began hooking up the rocker arms and making the proper adjustments. This meant adjusting the rockers so the valves would have a clearance of .015 in. for the Intake valves
and .030 in. clearance for the Exhaust valves.
With everything back in it's spot and torqued down to spec I was able to throw the manifold back on the head and step away from my first trip into a 3500 series Caterpillar Engine.
Well with everything back on the cat, and now it is time for my reflection of the week. It went well everything seemed pretty smooth. all week long, but that was just me. Now I saw plenty of other people who didn't seem to have had quite the experience with this assignment as I did. struggling a lot harder with things than they needed to. I think that I would dedicate my success on this assignment due to the having the 60 plus pages of specifications for the CAT 3500 series. It really helped have the ability to look different things up and know exactly what or how to do it.
These are some pictures of an Engine Research Assignment and an Engine Worksheet that I did at the beginning of the quarter before starting on the Detroit 60 series assignment and the CAT 3516 assignment.
These assignments definitely prepared and got me more familiar with different types of sensors and how they operate along with basic fuel systems there components and how they operate. There was also one page on cold start assist systems and how and when they function, I found this to be the most interesting part of the assignment due to the fact that I didn't know much about a cold start assist system. Now I do.
