INSTRUCTIONS FOR ASSEMBLY
1. Insert shaft into the coupling with the key in the
keyway. Ensure shaft is seated completely into the
coupling.
2. Your support table set up may vary, but we
recommend having access below the table to secure
shaft to build fixture (step 4).
3. Install the motor bracket to the build fixture by
aligning bracket holes with four hubs on fixture. Install
the shaft onto the fixture ensuring the coupling is
completely seated on the shaft stub.
4. Insert assembly fixture bolt from bottom of fixture and
screw into coupling with Allen wrench until tight.
5. Once the bracket and shaft are installed, insert the
lower impeller (with large collet nut) onto the shaft.

6. Tighten the nut to the torque shown in table 1.0.
7. Only on the first impeller, place the graphite disc on all
models with the exception of 360SSI in the SSI 6" Series
andmodels of the 10" SSI Series.
8. Slide diuser over the impeller and upthrust washer until it
is seated completely down on the motor bracket.
9. Repeat the steps to place the next diusers, inserting
theimpellers (A) first, and then adjusting as indicated
usinga torque wrench and the torque chart indicated
foreach pump (B).
When sliding the dierent diusers to cover the
impeller(C) and thereafter, we recommend checking
youralignmentwith respect to the welding point in
thediusers for a better final appearance (D).
Do this until you reach the discharge assembly.

10. Install the upper diuser (does not contain wear
ring) and the discharge. Make sure to align the strap
locations on the discharge with the holes in the
motor bracket.
Depending on the size of pump, the slot may have a
dierent configuration and location on the discharge.
11. Apply anti-seize (White Knight) to the threaded studs
on each strap. Insert strap into slot. Ensure strap is
completely seated into the slot. Slide threaded stud
into motor bracket mounting hole. Ensure the stud
extends through the hole.
12. To ensure straps are completely seated, use a rubber
hammer to tap them down.
13. Repeat Steps 11 and 12 for each strap.
14. Slide washer onto the stud and thread nut. Repeat
for other straps. Torque per Table 2.0. Recommend
tightening in a crisscross pattern to maintain even
torque on all sides.
For 10” models, place Strap Blocks on motor bracket
to prevent strap twisting during installation and
tightening process.
NOTE: The stainless steel strap nuts have been
anodized to prevent galling.

15. Remove the pump from the build fixture by
removing the fixture bolt from underneath the
fixture and lifting o the shaft stub. Lay the pump
horizontal on workbench or horizontal support.
CAUTION: On pumps with higher stage counts,
support center of pump when laying it horizontal to
prevent the pump from bowing.
16. Check that the pump shaft spins freely by inserting
the appropriate Motor Shaft tool into the coupling
and rotating.
17. Check that the shaft height is within the defined
range. See Table 3.0 for dimensions. Measure with a
shaft height gauge.

INSTRUCTIONS FOR ASSEMBLY
18. Apply Loctite® 302-43 to the set screw from the
motor coupling kit and reinstall the screw on the
shaft coupling.Use 5 mm Allen wrench to tighten.
19. Once secured, identify the cable guard included with
the corresponding pump model.
20. Cable Guard Assembly: For 6” pumps continue to
Step 21. For 8” pumps, go to Step 34.
21. Orient the cable guard so the angled tab is on the
motor bracket end and the top two tabs extend past
the pump’s discharge.
22. Install the cable guard tabs closest to the
motor bracket.
23. Gently tap the side of the cable guard to drive one of
the tabs under the strap.
• Do not tap the tabs.

INSTRUCTIONS FOR ASSEMBLY
24. Use the small flat-head screwdriver to gently
raise the strap on the opposite side of the cable
guard.
25. Gently tap the other tab under the strap.
Remove the screwdriver after the cable guard
tab has started under the strap.
26. The cable guard should be centered between
the two straps.
27. Repeat steps 23–26 for all the tabs except
the top two.
28. After all but the top two tabs have been
installed, gently tap the top end of the cable
guard down toward the motor bracket.
• Be careful not to damage or bend the cable
guard.
29. Apply pressure to the end of the cable guard
while tapping on the top side of the tabs close
to the motor bracket. This will allow for the end
of the cable guard to slide under the motor
bracket ears.
30. Gently tap the cable guard to drive one of the
top two cable guard tabs under the strap.
