1. Set motor on driver pads.
2. If the motor manufacturer has provided information on setting shaft end space in their manual
in the back of this manual, use those instructions to set the motor shaft end space. If not, then
set motor shaft end space as follows:
a. Push shaft into motor case until thrust collar butts against face of bearing as shown by
Figure 2-6; then select a reference point on motor case and mark shaft with pencil.
b. Pull shaft out away from bearing face (that is, toward pump) as far as it will go; then
using the same reference point that was selected in step a, mark shaft with pencil.
c. Measure distance between pencil marks; the distance (or total lateral movement) should
be at least 0.5 in (13 mm).
d. Set end space by pushing shaft back in toward sleeve bearing 0.13 in (3 mm) (see Figure
2-6). At this setting, there will be adequate end space between thrust collars and bearing
faces. For example, if total lateral movement is 0.5 in (13 mm) and the shaft is pushed
back in toward bearing face 0.13 in (3 mm) as described, the end space or clearance is
0.13 in (3 mm) on the drive end and 0.37 in (10 mm) on the opposite end; 0.5 in minus
0.13 in equals 0.37 in.
CAUTION
After setting end space the motor shaft must not be moved
prior to scribing location of hold down bolts.
3. Set driver so that distance between ends of driver and pump shafts is as specified by the
General Arrangement drawing. Also, if you have a gear-type coupling verify that dimension
D equals dimension L as shown by Figure 2-7; buttons as shown in figure are not installed on
spacer where couplings are the diaphragm or disk type.
