This week I have stayed really busy working on a CAT 3516. I have been doing a power pack on one of the cylinders. I learned a lot on how to measure certain items inside the engine and also how to use the measuring instruments correctly. I have found many issues with the engine I am been working on. I feel confident now measuring items inside the engine and knowing that I have the correct measurement.

This week we started working on engines in class. We took apart a John deer engine that had a hole in the side of it. We took it apart looking for the failure and what we found was not what we were expecting. We all made guesses and most of them were for a connecting rod. In the end we found out that it was the balancing shaft that failed and we used failure analysis to find out that one of the balancers came loose. That caused extra wear on the shaft and caused the failure.

This week we went deeper into diodes. We started exploring how a diode work and why it only travels in one direction. I have learned a lot on how the diode works internally and that has helped me to better understand what happens when they fail. Here is a video that helped me understand diodes.

This week I started back in class at school. I have started to learn about fuel injection pumps. I took apart a Bosch single-plunger fuel injection pump. I learned how simple these pumps can be and the many different types of pumps.
This week I learned about the pins that allow you to tilt the bucket on a Bobcat. The pins on the Bobcat are tapered. You fill behind it with grease and then pull tight with the bolt and that's what it pivots on.
