I'm at the assembly level of a full restoration of a T70 for my son. While trying to install a new chain we noticed the sprockets don't line up. Any suggestions? :confuse:

To get the sprockets to align you will need to add a machinery bushing or two on the shaft that has the small sprocket on it. You will have to take the large pulley off of that shaft and slide the shaft backwards out of the tube to add the washers. I don't remember what size shaft that is but just align the sprockets and measure how much room there is between the small sprocket and the bushing that is in the end of the tube. That would be the thickness of the bushings that you need to put in place. Machinery bushings/ washers are harder than regular washers and are smooth on both sides. When you put the drive pulley back on the shaft leave just a little bit of end play in the shaft and tighten the set screws that hold the drive pulley on the shaft.
It looks like you are doing a very nice job on this restore! Good luck!
