Thanks to advice from this forum, I changed the electric starter out on my recently acquired 06 450 Sportsman. It put up a bit of a fight but I got it out with some judicious use of newly made up obscenities and twisting and pulling. I put a bolt in the lower position with a shorter head height which made installing the new one quite a bit easier. Now onto the wheel bearings. Will freezing the bearings be enough to allow the new ones to slip into place or will some force still be necessary? I made a bearing press for dirtbikes using heavy threaded rod, flat washers and repurposing of my impact sockets. I figured something similar would probably work for the ATV as well.
