Tried to change my pinion today but turn out the hex thread is worn out. It's too near the motor mount for me to use my dremel to cut a slot so I'm pretty much stuck. Help?
Question: The PINION grub screw is 3mm. If I drill a hole say, 2mm into the center, would a 3mm screw extractor be usable? It's the smallest size I can find. I don't think I should drill a 3mm hole instead, right?
