1. Park the Massey Ferguson 202 on a level surface and block the wheels. Chock the rear wheels and make sure the tractor is securely immobilized against movement.
2. Place a jack under the rear axle and jack the rear axle up to take the load off the rear wheel bearings.
3. Remove the wheel and hub from the axle.
4. With a micrometer, measure the exact distance from the end of the axle shaft to the end of the wheel hub bearing. This is call the end fit or the pre-load distance. Make sure to record this measurement.
5. Remove the spacer, bearing small adjusting nut and the large adjusting nut.
6. Adjust the end fit by screwing on the small adjusting nut and the large adjusting nut until the distance between the axle and the wheel hubbearing is the same as your recorded end fit.
7. Put the spacer back between the adjusting nuts.
8. Tighten the small adjusting nut and the large adjusting nut until they are snugly together but not overtightened.
9. Test the adjustment with a torque wrench before you replace the wheel. The adjustment should be within the specifications in the Massey Ferguson 202 manual.
10. Replace the wheel and hub.
11. Lower the jack to the ground.
12. Test the wheel bearings for proper operation by jacking the tractor up and spinning the wheel. The wheel should spin with minimal resistance and no wobble.
