This isn't our normal line of work, but the crankshaft grinder is the perfect machine to repair a worn out John Deere axle shaft! When the axle shaft has worn to the point that the bearing is loose, the OD of the shaft must be turned to the proper diameter for the replacement undersize bearing. In part 1, we measure and prepare the axle to be ground. #engine #machineshop #enginemachineshop #rebuild #tractor #johndeere #machining #business #smallbusiness #familybusiness #coloradobusiness #work #w
