1.
If the coupling adapter (9) and tie rods (6) have
not been disassembled from the motor (3), skip
to step 2.
If the coupling adapter (9) and tie rods (6) have
been disassembled from the motor (3), follow
these steps:
a.
Screw the tie rods (6) into the motor (3) and
torque to 50-60 ft-lb (68-81 N•m).
b.
Screw the coupling adapter (9) into the motor
shaft and torque to 90–100 ft-lb (122–135
N•m).
c.
Reassemble the pump to the motor. Use
the applicable instructions for your pump
(
or
).
d.
Continue to step 2.
2.
Assemble the coupling nut (11) to the piston rod
(R).
3.
Orient the lower (7) to the motor (3). Position
the lower (7) on the tie rods (6). Lubricate the
threads of the tie rods (6).
4.
Screw the tie rod locknuts (8) onto the tie rods
(6). Tighten the locknuts (8) and torque to 50-60
ft-lb (68-81 N•m).
5.
Insert the collars (10) into the coupling nut (11).
Tighten the coupling nut (11) onto the coupling
adapter (9) and torque to 90–100 ft-lb (122–135
N•m).
6.
Flush and test the pump before reinstalling
it in the system. Connect hoses and flush
the pump. While it is pressurized, check for
smooth operation and leaks. Adjust or repair
as necessary before reinstalling in the system.
Reconnect the pump ground wire before
operating.
NOTE:
NOTE:
NOTE: When used with E-Flo DC motors, Dura-Flo
lowers require a check valve (35) to be installed.
