My 17 year-old Noma snowthrower has a scored impeller shaft on the second stage. Last winter the bearing assembly on the stage housing failed and now the 7/8" steel shaft is about 3/4" for about an inch.
I'm having trouble finding the part although I can get the bearing assembly. The impeller and shaft are all one piece. Is there anyway to augment the scored section and restore it to the original diameter? Is any kind of welding an option? I suspect there isn't any kind of mild steel duct tape.
Keeping this thing running has become somewhat of a hobby for me. I'm guessing it's time to get a new one and pay more attention to preventative maintenance.
Thanks.
