that it is aligned in the cassette
so that the face is equidistant
from each post. If not, loosen
the bearing mounting bolts and
adjust as necessary. Flange
bearing units have jack bolts
(see Figure 19). Pillow block
bearing units require shims to
adjust the bearing up or down
(see Figure 20). Retighten
bearing mounting bolts once
alignment is correct.
13 Install bearing cover plates.
Remove blocks supporting
wheel. Install belts.
