This week we took apart a John deer engine that had a hole in the side of it .we followed the clues to the failure as a class. Everyone thought that it was a failed connecting rod but it turned out to be the counter weight came loose and destroyed the balancing shaft and when that broke it shot through and poke a nice big hole in the cast. We also choose a group engine to disassemble. And after that I will start to disassemble a cat 3516 engine by myself. Time last week: 35 Time this week: 30 Time total: 162
