and vertical planes. Final alignment should be
made by moving and shimming the motor on the
base plate, until the coupling hubs are within the
recommended tolerances measured in total run-
out. All measurements should be taken with the
pump and motor foot bolts tightened. The shaft of
sleeve bearing motors should be in the center of
its mechanical float.
NOTE: Proper alignment is essential for correct
pump operation. This should be performed after
base plate has been properly set and grout has
dried thoroughly according to instructions. Final
alignment should be made by shimming driver
only. Alignment should be made at operating
temperatures.

ANSI/OSHA COUPLER GUARD
REMOVAL/INSTALLATION
WARNING: Unexpected Start-up Hazard
Disconnect and lock out power before
servicing. Failure to follow these instructions could
result in serious personal injury or death and
property damage.
NOTE: Do not spread the inner and outer guards
more than necessary for guard removal or
installation. Over spreading the guards may alter
their fit and appearance.
Removal
a. Remove the two capscrews that hold the
outer (motor side) coupler guard to the
support bracket(s).
b. Spread the outer guard and pull it off the
inner guard.
c. Remove the capscrew that holds the inner
guard to the support bracket.
d. Spread the inner guard and pull it over the
coupler.
Installation
a. Check coupler alignment before
proceeding. Correct if necessary.
b. Spread the inner guard and place it over
the coupler.
c. With the inner guard straddling the
support bracket, install a capscrew
through the hole (or slot) in the support
bracket and guard located closest to the
pump. Do not tighten the capscrew.
d. Spread the outer guard and place it over
the inner guard.
e. Install the outer guard capscrews by
following the step stated below which
pertains to your particular pump:
i. For pumps with a motor saddle support
bracket: Ensure the outer guard is
straddling the support arm, and install
but do not tighten the two remaining
capscrews.
ii. For pumps without a motor saddle
support bracket: Insert the spacer
washer between the holes located
closest to the motor in the outer guard,
and install, but do not tighten, the two
remaining capscrews.
f. Position the outer guard so it is centered
around the shaft, and so there is less than
a 1/4" of the motor shaft exposed. On
guards that utilize a slotted support
bracket, the inner guard will have to be
positioned so there is only a 1/4" of the
pump shaft exposed.
g. Holding the guard in this position, tighten
the three capscrews.
