20. Install the upper impeller (15a) onto the shaft (31) with the

impeller nut (13) and o-ring (14).

21. Loosen all spacer bolts (43) to set the clearance between the

lower casing and the lower impeller.

22. Select three alternating adapter ring spacers (37) to adjust for a

.015 to .020 inch clearance between the lower casing and the
lower impeller.  Adjust the spacers to obtain a level adjustment.
Tighten the three spacers using the base plate screws (43) to
secure the setting.  Recheck the clearance to ensure proper
adjustment.

23. Adjust the three remaining spacers (37) to take up the gap

between the end of the spacer and the base plate.  (Also takes up
slack in the threads of the first 3 spacers to prevent casing
movement due to thread clearances.)

24. Tighten the three remaining screws (43) of the spacer to the base plate

connections.

24. Remove the upper impeller (15a).

25. Place the lower screen (12) inside the lower casing (11b) with the pin on the

screen facing upward and lined up with the step in the lower casing.

26. Install the diffuser plate (51) on the lower casing (11b), ensuring that the

pin in the plate fits in the notch in the lower casing.  (The pin in the lower
screen must also fit inside the notch on the diffuser plate.)

27. Install the  back plate (17).

28. Install the upper impeller (15a) onto the shaft with the impeller nut (13) and o-ring (14).

29. Install the upper screen (12) with the pin down.  Rotate the screen counterclockwise until it rests

against one of the tabs on the back plate (17).
