11.Bolt the casing cover to the rear casing using the (4) hex socket head bolts (Item 8).
Tighten the bolts evenly to avoid binding, and torque in accordance with the torque
table on page 9. Check for free rotation of the assembly
12.Place impeller key (Item 15) into the shaft keyway with
material stamp facing up and slide the impeller (Item 2)
onto the shaft.
Tighten and torque the impeller nut and then secure the
impeller nut with the set screw (Item 11). [This completes
the rotating assembly, also called the PB assembly.]
13.Mount the rotating assembly to the frame adapter (Item 50)
using the four hex head bolts (Item 67). Evenly tighten the
bolts and torque in accordance with the torque table on
page 9.
14.Mount the outer magnet (Item 48) on the motor shaft.
Tighten the outer magnet set screw (Item 76) and torque in accordance with the

side of tape or similar material.
15.For MHL pumps be sure the (3) heat insulation sheets (Item 101) are in place between
the motor C-face flange and the frame adapter for this step. Install the motor to the
frame adapter using caution as strong magnetic forces will
pull the magnets together.
