ASSEMBLY

1.Clamp the long bearing press into the vise.

2.Push the new bearing over the front axle. Insert the axle into the bearing press (Fig. 4J).

2.Place the wheel over the axle and pull the axle out by about 10 mm (1/2 inch). Push the second bearing over the axle and into the hub.

3.Center the axle using the short bearing press.

4.Tap both bearings into place with the hammer (Fig. 5J) at the same time.

Turn the axle to check the bearings. You should not be able to feel any irregular friction. Make sure that there is no play in the axle.

After completing assembly of the hub, check its func-

tion by spinning the axle with your fingers. It should rotate freely without irregular friction. A small amount of lateral play is acceptable if the play is eliminated when the wheel is installed with the quick release properly closed.
