I have a Snap-On 7115 that is still used for front line work. I like it. I changed the gear from 20 teeth to 24 but was wondering if I can upgrade to 32 teeth? I have a gear from a SL-710 in it now that is 32 teeth. It works fine but the gear does not go all of the way through the bushing. Is there a bushing I can swap out?
