seated.
2. Coat the motor shaft with an anti-seize compound.
3. Slide the shaft coupler onto the motor shaft until fully seated, and tighten the
two set screws.
4. Place the motor adapter onto the motor, such that the one drain hole is locat-
ed down and the four side access ports are horizontal when the pump is rein-
stalled.
5. Coat the round end of the pump shaft and shaft key with an anti-seize com-
pound.
6. Place the pump liquid-end assembly with pump shaft and shaft key into the
motor adapter, with the key aligned with the coupler key way.
7. Install the four (4) 5/16-18NC bolts and tighten.
8. Using a wood dowel, place it against the pump shaft end located in the dis-
charge port. Tap on the end of the wood dowel until the pump shaft is fully
seated in the shaft coupler, and then tighten the cone-point set screw
(Figure 4.6, Removal of Mechanical Seal Holder from Motor Adapter).
