So, I had a couple of good 5-hour runs the last couple of days and as I was shutting down I heard a strange squeak and thought I would investigate today thinking maybe something was a little loose in my Foundation or something needed a little more oil. Oil and splash system look great, everything looks Rock Solid and then I suddenly noticed that one of the flywheel Keys was about an inch out. In My Memory these things have been practically rested in place for years. Why would a key suddenly start trying to come out? I have this different Italian alternator on here and maybe there's some difference in the balance? Any suggestions on what I should do other than just pound the key in harder?
