1st week of Diesel Engines

One valuable piece of information I learned was about the Craknshaft Position Sensor. It tells the computer the exact position and RPM of the crank shaft. This allows the computer to control the timing and lets it know whether to advance or retard it. Another thing I've learned is when taking off a head you take the bolts out a certain way. Same goes for when you're torquing down the headbolts. You want to do it in the correct order so that the headgasket is compressed evenly.

For our engine we chose the straight six Mack engine.

We begin to disassemble the top of our engine.

Jeff continued his failure analysis. The conclusion that he came to was the balancing shaft broke which led to catastrophic failure.
