The top sprocket is the drive sprocket, the lower one is the steering sprocket. The bevel gears are locked together with set screws tightened onto shaft flats. The fork and the widest shaft coming down on the outside are welded together. The driveshaft with the bevel gears on them are perfectly machined to no move, everything is spaced evenly with washers so there is no movement. When steering, the drive system is locked so there will be no back drive. The wheels only options are to slip. All of our chains will be tensioned with idler sprockets. The idlers will also force the chain 1/2 way around the drive motors. This means there will be more chain on the drive sprockets to prevents chain slipage.
