To even attempt to repair something like that is not for an amateur. You would need to find someone highly specialized in cast iron repair and it wouldn't be cheap. A replacement would be your best bet. Being that it broke on the splines, the broken pieces are pretty much useless now. Maybe??? you could talk to a machine shop and see if they could machine a bigger hole in the wheel to accept a new splined section that would need to be made. George MD could probably give you some good advice as he works a lot with cast. I have read that heating cast red hot and using a spray welding technique has been used to successfully repair large machinery castings. Basically powdered iron is sprayed and fuses to the hot cast iron as if it were cast that way. Spray welding is commonly used to build up worn shafts. A specialty welding company like Eutectic-Castolin may be a good starting point. Although 7018 can be used for non critical cast repair and specialty rods can repair cast, on something critical like a wheel, you want to do it right. If it was just a cover plate or something like that, then you could look at simpler repairs. Hope this helps. Dave
