My 99 Craftsman GT keeps having the crank pulley (Kohler 20HP Vertical shaft) bolt loosen. I've pulled it out, checked the threads, lock washer is intact, cleaned it and installed blue Loc-Tite, but it still comes loose 3-4 times a season. I do try to check it regularly, but when I miss it, loose again.
Should I just replace the bolt and washer ?
What am I missing here ?
