Tazza, Thanks,I was going to ask that question about reweld and axel pull. You are right ,not enough room to remove bolt. Everything going good now with the help from all of you. Two more questions , where to get a decent shop manual ot parts manual ?Have a 773 also, does anyone have a manual to cover ,as best as you can, both of them ? Last, how do you torque the bolt on the end of the axel that hold the sprockett on ? Thanks , Butch
