Tools Used

Remove belt and pulley. Remove blade from inside the deck. Remove three screws that attach the housing to the mower deck. The shaft and bearings were still ok, but I replaced them with new anyway, was the best thing to do. The three screws are self threading, one of which was hard to get started, but after awhile with pressure and turning at the same time it tightened up. all-in-all it went pretty easy. I wasn't so fortunate on my next project with putting tubes in my tires.
