Assembly Instructions
1/3 to 3 HP 56C Frame
1. Make sure all the components of the kit are clean, free of burrs and t
properly during the assembly process.
2. If applicable, remove the protective lm from the motor shaft. Make
sure that each motor has the slinger properly installed. This slinger is
very important and it prevents water from entering the motor along the
shaft.
3. Apply anti-seize on the inside of the shaft coupling and install it on the
motor shaft. Make sure that the set screws are in line with the keyway
and that their tips rest at on the bottom of the keyway. Do not tighten
the set screws.
4. Position the pump bracket with the nameplate area on the top. Install
the bracket with four bolts.
Do not misalign or bind the bracket when you are tighten-
ing the bolts.
Tighten the bolts in a diagonal pattern to the following torque speci-
cations:
• 3/8” bolts to 20 ft-lb,
• 1/2” bolts to 45 ft-lb
• 5/8” bolts to 93 ft-lb
5. Adjust the distance between the shoulder of the shaft coupling and
the bottom of the mechanical seal pocket according to the table below
the drawing. The adjusting distance (X in the drawing and table) in-
sures that the spring of the mechanical seal has the proper tension.
6. Tighten the set screws at the shaft coupling to a torque of 108 in-lb.
7. Apply P80 lubricant emulsion or an equivalent on the mechanical seal
o-ring cup and install it into the bracket. It is very important to keep
the sealing surfaces as clean as possible. Therefore, avoid touching
them and keep them clear from residue and debris.
8. Apply P80 lubricant emulsion or an equivalent on the mechanical seal

bellows and spring and install them on the motor shaft coupling. Again, the sealing surfaces should be kept as clean as
possible. Therefore, avoid touching them and keep them clear from residue and debris.
9. Install the impeller on the shaft coupling. Use 242 Locktite or an equivalent locking compound on the threads. Make sure
the impeller hub is tight against the shoulder of the shaft coupling. Make sure the spring retainer at the mechanical seal is
in the proper position against the hub of the impeller.
10. If it is supplied, install the jam nut on the shaft coupling and tighten it against the impeller. Use 242 Loctite or an equivalent
locking compound. Tighten the jam nut to a torque of 45 ft-lb.
11. Apply P80 lubricant emulsion or an equivalent on the large o-ring and then install it on the outside diameter of the bracket.
12. Carefully place the volute into position. With the discharge pointing in the desired position, install the required quantity of
bolts.
Tighten the bolts in a diagonal pattern to the following torque specications:
• 3/8” bolts to 20 ft-lb,
• 1/2” bolts to 45 ft-lb
Do not misalign the volute when you are tightening the bolts. Align it carefully and take care not to pinch the
o-ring.
13. Rotate the impeller by hand and make sure that it rotates freely. Tightness of the impeller implies a bind or a misalignment.

5 to 50 HP JM Frame
1. Make sure all the components of the kit are clean, free of
burrs and t properly during the assembly process.
2. If applicable, remove the protective lm from the motor
shaft. Make sure that each motor has the slinger prop-
erly installed. On 50 HP (230/460 V) motors, remove the
metal slinger and replace it with the slinger from the kit.
This slinger is very important and it prevents water from
entering the motor along the shaft.
3. Install the small square ring on the motor shaft. Apply
P80 lubricant emulsion or an equivalent on the small
o-ring and then slide it up against the square ring.
4. Apply anti-seize on the inside of the shaft sleeve and
then slide it over the motor shaft with the stepped end
against the motor shaft shoulder. The sleeve must slip
over the lubricated rings and sit rmly against the motor
shaft shoulder.
5. For DC4 models only: Install the compression hose
connector in the bracket using a Teon sealant or an
equivalent.
6. Apply P80 lubricant emulsion or an equivalent on the
mechanical seal o-ring cup and install it into the bracket.
It is very important to keep the sealing surfaces as clean
as possible. Therefore, avoid touching them and keep
them clear from residue and debris.
7. Position the pump bracket with the nameplate area on
the top. Install the bracket with four bolts.
Do not misalign or bind the bracket when you
are tightening the bolts.
Tighten the bolts in a diagonal pattern to the following
torque specications:
• 3/8” bolts to 20 ft-lb,
• 1/2” bolts to 45 ft-lb
• 5/8” bolts to 93 ft-lb
8. Apply P80 lubricant emulsion or an equivalent on the
mechanical seal bellows and spring and install them
on the motor shaft sleeve. Again, the sealing surfaces
should be kept as clean as possible. Therefore, avoid
touching them and keep them clear from residue and
debris.
9. For DC4 models only: Lubricate the inside of the brack-
et (hub) wear ring with petroleum jelly or an equivalent.
10. Place the square key into the shaft keyway and carefully
slide the impeller over the motor shaft.
For DC4 models only: Make sure the spring retainer at
the mechanical seal is in the proper position against the
hub of the impeller.
For all the other models: Discard the spring retainer at
the mechanical seal.
11. Push the impeller towards the bracket until it contacts the
shaft sleeve. Install the impeller washer and the impeller
bolt at the shaft end. Use 271 Loctite or an equivalent
locking compound. Tighten the bolt to the following
torque specications:
• 3/8” bolts to 21 ft-lb,
• 1/2” bolts to 90 ft-lb
12. Apply P80 lubricant emulsion or an equivalent on the
large o-ring and then install it on the outside diameter of
the bracket.
13. For DC4 models only: Install the compression hose
connector in the volute using a Teon sealant or an
equivalent.
14. For DC3 and DC4 models only: Lubricate the inside of
the volute wear ring with petroleum jelly or an equivalent.
15. Carefully place the volute into position. With the dis-
charge pointing in the desired position, install the re-
quired quantity of bolts.
Tighten the bolts in a diagonal pattern to the following
torque specications:
• 3/8” bolts to 20 ft-lb,
• 1/2” bolts to 45 ft-lb
Do not misalign the volute when you are
tightening the bolts. Align it carefully and take
care not to pinch the o-ring.
16. Rotate the impeller by hand and make sure that it rotates
freely. Tightness of the impeller implies a bind or a mis-
alignment.
17. For DC4 models only: Install the polypropylene tubing
into the compression hose connectors.
