DRIVE END ASSEMBLY
(
ANSI OR ISO PUMPS WITH IEC MOTORS)
(-B5
FLANGE
ONLY)
10-a. MOUNTING ADAPTER, OUTER DRIVE AND FOOT
1.
Place the motor vertically on worktable or floor so that shaft is pointing upwards. Be sure to cover
the work surface with corrugated cardboard or similar material to prevent damage to the fan cover.
Caution!:
Motors with plastic fan covers may be damaged in the vertical orientation. Perform
the following assembly in the horizontal orientation.
2.
Place the motor mounting plate on the motor flange. The motor mounting plate for 80 and 90 frame
motors has the rectangular boss facing upwards. For the 100/112, 132 and 160 frame motors have
the rectangular boss facing downwards. Bolt the motor mounting plate to the motor flange with the
appropriate four bolts. See figure 10-1.
3.
Place the round end of the IEC bracket onto the motor mounting plate and line up the holes. Use
four 12mm X 35mm hex head bolts with lock washers to secure the bracket to the motor mounting
plate. Tighten bolts to snug only.
4. Back out both of the set screws on the outer drive hub so they do not protrude into the bore. Slide
the outer drive onto the motor shaft making sure that the shaft key is in place. Position the outer
drive so that the groove in the outer drive lines up with the end of the b1/16”, -0” (+1.6mm,
-0mm.) Tighten the two set screws to 10 ft-lb (13.6 N-m.) See Figure 9-1. Figure 10-1 shows the
outer drive position with respect to the motor mounting plate for reference. Install the 3/8” NPT
pipe plug into the hole on top of the adapter plate. This is to keep dirt out of the motor shaft area.
