How do you adjust axle end play on a 1959 Massey Ferguson?

To adjust axle end play on a 1959 Massey Ferguson, first, raise the tractor and remove the wheel to access the axle. Check the end play using a dial indicator; if it exceeds the specified range, loosen the axle bearing retainer nuts. Adjust the shims or spacers to decrease the end play, then re-tighten the retainer nuts and recheck the end play to ensure it's within the acceptable limits before reassembling the wheel.
