Install the coupling guard
1. Is the end plate (pump end) already installed?
• If yes: Make any necessary coupling adjustments and then proceed to step 2.
• If no: Complete these steps:
a) Remove the spacer portion of the coupling.
Refer to the instructions from the coupling manufacturer for assistance.
b) If the coupling hub diameter is larger than the diameter of the opening in the end plate,
then remove the coupling hub.
c) Remove the thrust bearing end-cover screws.
d) Align the end plate to the thrust bearing end cover so that the holes in the end plate
align with the holes in the end cover.
e) Replace the three thrust bearing end cover screws and torque to the values shown in
the Maximum torque values for fasteners table.
f) Replace the coupling hub (if removed) and the spacer portion of the coupling.
Refer to the instructions from the coupling manufacturer for assistance.
Complete any coupling adjustments before you proceed with the coupling guard assembly.
2. Slightly spread the opening of the coupling guard half and place it over the pump end plate.
The annular groove in the guard is located around the end plate.
Position the opening (flange) so that it does not interfere with the piping but still allows for
access when you install the bolts.
