Had a mishap yesterday when I was coverting my deck from mulching to Power Flow Bagging. The last blade bolt wouldn't come off with my impact wrench so I needed to use a pipe extender to get enough leveage to get it off. Turns out the spindle and bolt threads are both stripped so I have to either get a new spindle from my dealer or have it rethreaded along with a new bolt. The spindle can be removed so I am assuming that I don't have to get an entire assembly which includes the housing, pulley wheel and dust cap. Anybody know what is the case or whether dealers typcially have equipment to rethread spindles. I assume getting a replacement part is the best way to go but I have never had to replace one of these before.
