Got the G12 back together this morning and started on the back end. Adjusted the axle end play, which was good to start with but noticed the right rear wheel had a lot of side play after the axle adjustment. Looks like the end of the hub are wore some to allow this play. I found a shim just under 1/8" that would just slide over the axle. Slide it on then the hub and snugged the nut down to were it was just free and took out the side play. My question , is this going to cause any problems as I am sure it was not meant to be adjusted this way. This is a good solid old tractor yet and don't want to do anything to mess it up down the road. Thanks for your advise.
