40 hrs week 1/14/-1/18/2013 to date 120 hrs

This week I worked on taking the cab off the f 550 in the shop. I learned that its not to hard to take a cab off if you have the right tools, I made a glow plug tool to easily remove the glow plug electrical connectors  and it works great.At Williams I have been helping replace bearings on a Ingersol Rand engine  a set of bearings had extreme wear and was releasing shavings,The  problem was that we had prior installed some bearings on a rod to  the compressor side,and did not see a protrusion   which was on the rod  cap which then was rubbing against the aluminum bearing side face, causing metal loss which potentially caused the engine to shut down because of the filtering  system it has installed  which is there to save the engine .I also was removing fuel valves  and replacing them, the fuel valves have o rings and sometimes leak gas out or have a buildup of black hardened substance from the fuel burn and cause a week burn inside the piston chamber,  which then activates the alarms ,the process then is a sequence of  safety steps  desighened to protect us.in order to fix the problem.Each of the pistons is monitored by an Allen Bradley monitoring system and it shows individual heat temperatures for the pistons . That's how we find out which valve is bad because of the low temp readings compared to the other pistons usually about 835 degrees  .
