Field Installation of the 8 x 8-inch Coupling
1.
Place the motor in a vertical position.
NOTICE:
A motor and pump should always be coupled in a vertical position to ensure correct
alignment and prevent any chance of bending or damaging to either shaft.
2.
Clean the pump and motor shafts of debris.
3.
Check to ensure the shafts rotate freely.
4.
Generously lubricate the motor shaft splines.
NOTICE:
Use a non-toxic FDA-approved waterproof grease – (Mobile FM102, Texaco CYGNU2661, or equivalent).
5.
Install the coupling on the pump.
6.
Lightly tighten one of the coupling set screws.
7.
Align the pump such that the motor leads will be correctly positioned with the lead notch in the pump's
mounting flange.
8.
Lower the pump so the mounting holes are aligned and the pump's weight is supported by the motor face.
9.
VERIFY THE PUMP SHAFT WAS LIFTED 1/8" DURING THE PREVIOUS STEP. This is critical to ensure the
impellers are correctly positioned in the pump bowls.
10. Install and tighten the motor and pump mounting bolts.
11. Align the coupling splines with the motor shaft splines and pull the coupling down as far as it will slide on the pump
shaft.
NOTICE:
When the coupling is correctly positioned, only a small amount (~ 1/8") of the end of the motor splines will be
visible.
12. Apply Loctite 243 and firmly tighten the set screws in the coupling.
