Plowing snow a bit back and the 100 made an odd sound and some white steam. My first thought was blown head gasket.
I pulled the head last week and didn't see anything strange with the gasket. Looking a bit closer I saw that #3 sleeve looked like it was up about 1/16". I turned the motor with the hand crank and yup - I pushed the sleeve right out of the block. Looking at pistons #1, 2, & 4, they are all stamped with part number 362867R1. #3 has a different identifier stamp and is actually a different "color". The tractor ran well before this problem. My questions are:
Likely causes for the loose sleeve?
Do I need to replace the sleeve? (One piece of unsolicited advice was to lok-tite it and push it back in to place.)
If I need to replace the sleeve, do I need to replace the piston as well?
