Need suggestion for repair of older craftsman square gearbox
Hey my old craftsman tried to eat a chunk of concrete and lost. Took everything apart and the gear the goes on the impeler shaft is broke. I don't have a part number or manual, just an 80's 10.5 hp Briggs and Stratton with dual stage 30 in cut. Can't even locate a model number on the blower. This gear box is steel square and I can't get it off the end of the impeller shaft. Just has two pieces on the sides that come apart with 6 bolts and you can take it off the auger shaft that way. Any suggestions, I'm ready to throw this thing away.
