MACHINERY AND TOOLS
Submersible Tools & Equipment
The minimum basic manual tools and the equipment needed to assemble submersible pumps are:
1. Vernier Caliper type Height Gage, 0-150 mm for verifying the height of the arrow
2. Ratchet for 11/16” fastening screws
3. Ratchet for 3/4” fastening tension screws
4. Allen wrench - 5 mm (for 6”, 8”, and 10” motor coupling), SAE or standard (T handle preferred)
5. Adhesive Loctite® 302-43
6. Rubber hammer
7. 19 mm and 24 mm sockets, 3/8 drive
Additional machinery and equipment would be required if the assembler wants to cut and remove the
rough edges of the motor and cable guards.

ASSEMBLY INSTRUCTIONS
Bracket and Shaft Installation
1. Insert shaft into the coupling with the key in the key-way.
2. Ensure shaft is seated completely into the coupling.
3. Install the motor bracket to the build fixture by aligning bracket
holes with four hubs on fixture.
4. Install the shaft onto the fixture, ensuring the coupling is com-
pletely seated on the shaft stub.
• Support table set up may vary, but access below the table
is recommended to secure shaft to build fixture.
5. Insert assembly fixture bolt from bottom of fixture. Screw into
coupling with Allen wrench until tight.

Impeller & Diffuser Installations
1. Insert the lower impeller (with large collet nut) onto the shaft.
• Use two flathead screwdrivers to pry the threaded collet
nut and screwdriver shaft over the impeller to force the
impeller lower into the pump shaft.
2. Tighten the nut to the correct torque.
3. Only on the first impeller, place the graphite disc on all models
with the exception of 360SSI in the SSI 6” Series and the 10” SSI
Series models.
4. Slide diffuser over the impeller and upthrust washer until it is
seated completely on the motor bracket.

5. Repeat the steps to install next diffusers until you reach the dis-
charge assembly.
• Insert impellers (A).
• Adjust as indicated using a torque wrench and the torque
chart indicated for each pump (B).
• When sliding the different diffusers to cover the impeller
(C) and thereafter, check the alignment to the welding
point in the diffusers for a better final appearance (D).
NOTE: On all subsequent impellers using upthrust collet nut,
use two flathead screwdrivers between the collet nut and
impeller to pry down on the impeller and force it lower into the
pump shaft for proper seating.
Strap Installations
1. Install the upper diffuser (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 differ-
ent configuration and location on the discharge.
2. Apply anti-seize (White Knight) to the threaded studs on the
strap.
3. Insert strap into slot so it is completely seated.
4. Slide threaded stud into motor bracket mounting hole.
• Ensure the stud extends through the hole.

5. Use a rubber hammer to tap the strap down to ensure it is com-
pletely seated.
6. Repeat steps 1 - 5 for each strap.
7. Slide washer onto the stud and thread nut for each strap.
8. Tighten to the correct torque.
• Refer to table below.
• Tightening in a crisscross pattern is recommended to main-
tain 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 pre-
vent galling.

Preparation and Inspections
1. Remove the pump from the build fixture by removing the fix-
ture bolt from underneath the fixture and lifting off the shaft
stub.
2. Lay the pump horizontally on the workbench or horizontal sup-
port.
3. Check that the pump shaft spins freely by inserting the appro-
priate Motor Shaft tool into the coupling and rotating.
4. Check that the shaft height is within the defined range.
• See table for dimensions.
• Measure with a shaft height gauge.
Risk of damage to pump or other equipment.
• On pumps with higher stage counts, support the center of the pump when laying it horizontal to pre-
vent the pump from bowing.

5. Apply Loctite® 302-43 to the set screw from the motor coupling
kit.
6. Reinstall the screw on the shaft coupling, using a 5 mm Allen
wrench to tighten.
NOTE: If coupling O-Ring is not installed, place the O-Ring into
the coupling O-Ring groove, making sure it is placed properly.
7. Once secured, identify the cable guard included with the corre-
sponding pump model.
6” Pump Cable Guard
1. Orient the cable guard so the angled tab is on the motor
bracket end and the top two tabs extend past the pump’s dis-
charge.
2. Install the cable guard tabs closest to the motor bracket.
3. Gently tap the side of the cable guard to drive one of the tabs
under the strap.
• Do not tap the tabs.

4. Use the small flat-head screwdriver to gently raise the strap on
the opposite side of the cable guard.
5. Gently tap the other tab under the strap.
• Remove the screwdriver after the cable guard tab has
started under the strap.
6. Make sure the cable guard is centered between the two straps.
7. Repeat steps 3-6 for all the tabs except the top two.
8. 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.
9. 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.
10. Gently tap the cable guard to drive one of the top two cable
guard tabs under the strap.
