4. Tighten the castle nut (right-hand threads) to take up all the internal play. The tapered roller
bearings will be firmly in contact with the hub shoulders, support ring, spindle, and castle nut,
and the rotation of the hub or wheel will drag slightly.
5. Loosen the castle nut until there is no more friction between the castle nut and outer bearing.
Make sure that the hole for the cotter pin or hair pin clip lines up with the nearest notch in the
nut.
6. Tap the hub with a mallet to make sure the assembly is seated.
7. Check that the hub rotates freely. It is better that it be slightly loose than too tight. If needed,
repeat steps 4 and 5.
8. Once it has been adjusted properly, insert a new cotter pin or the hair pin clip, as appropriate.
9. Put the hubcap back on.
10. Put the wheel back on (see "Assembling and attaching the wheels" on page 72 and
"Tightening the lug nuts" on page 73).
Once the wheel is back on, turn it slightly. The wheel should come to rest with a slight rocking
movement.
