Taking everything off to get to the gear assembly including moving gas tank, top of dash, dropping the front of the deck, removing front tires...After fighting with the phillips screw at the bottom of steering shaft for an hour finally had to use torch to heat it then use the 1/2\" impact to break it loose...If you follow your exploded pa rts list and not lose any parts this repair is just time consuming but is not that hard...
