Coupling Guard Removal and Installation (Non CE version)
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.
A1.1 Removal
1.
Remove the two (2) cap screws that hold the outer (motor side) coupler guard, (item 1); to the support
bracket(s), (items 3 (and item 6)).
2.
Spread the outer guard and pull it off the inner guard, (item 2).
3.
Remove the cap screw that holds the inner guard to the support bracket, (item 3).
4.
Spread the inner guard and pull it over the coupler.
A1.2 Installation
1.
Attach the Support Brackets, (items 3 and 4 preassembled); to the bearing housing, (if a new installation).
Spread the inner guard, (item 2); and place it over the coupler.
2.
With the inner guard straddling the support bracket, (item 3); install a cap screw through the hole (or slot) in
the support bracket and guard located closest to the pump. Do not tighten the capscrew.
3.
Spread the outer guard, (item 1); and place it over the inner guard.
4.
Install the outer guard cap screws by following the step stated below which pertains to your particular
pump:
4.1 For pumps with a motor saddle support bracket, (item 5): Ensure the outer guard is
straddling the
support arm, (item 6); and install but do not tighten the two remaining cap screws.
Locate the support arm, (item 6) between the outer guard ends, align the support arm with the holes in
the outer guard and the holes in the motor saddle support bracket, (item 5).
4.2 For pumps without a motor saddle support bracket: Insert the spacer washer, (item 7); between the
holes located closest to the motor in the outer guard, and install, but do not tighten, the two remaining
cap screws.
5.
Position the outer guard so it is centered on the shaft, and so there is less than a 1/4 in. (6.35mm) 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 in. (6.35mm) of the pump shaft exposed.
6.
Holding the guard in this position, tighten the three (3) cap screws.
