Table 6-1 Installation Data , and secure the
motor hub with a setscrew. When the hub gap is
properly set, you will be able to move the element
in a slight back and forth motion (unless the cou-

STEP 2 - ANGULAR ALIGNMENT
Clean fluid and dirt from the hubs in preparation for
angular alignment. Position the dial indicator on the
hubs as shown in Figure
6-8 . Rotate both hubs
equally to check alignment.
STEP 3 - PARALLEL OFFSET ALIGNMENT
Reposition the dial indicator as shown in Figure 6-
8 . Rotate both hubs equally to check for misalign-
