5. Slide the outer drive magnet assembly (item 17) onto
the motor shaft until the motor shaft contacts the snap
ring in the bore of the drive. See figures 4 & 5.
6. Secure the drive on the motor shaft.
WARNING
: Be careful, magnets will try to attract tools.
Metric Motors: Secure the drive to the motor shaft us-
ing bolt, lock washer and flat washer (items 25, 26, 27).
Thread the bolt into the end of the motor shaft (while
holding the outer drive to prevent it from turning).
See figure 6.
Tighten the bolt to the following:
• 63 frame (M4) = 15 in-lb (1.7 N-m)
• 71 frame (M5) = 30 in-lb (3.4 N-m)
• 80 frame (M6) = 90 in-lb (10.2 N-m)
• 90 frame (M8) = 130 in-lb (14.7 N-m)
NEMA Motors: Install (2) 3/8” set screws (item 17B)
into threaded holes on the side of the outer drive magnet
assembly. Using a 3/16” Allen wrench, tighten to 228
in-lbs (25.8 N-m). See figure 7.

7. Install the pump end on the motor/drive magnet as-
sembly. With the motor/outer drive magnet assembly in
a horizontal position, securely clamp to the workbench.
NOTE: If the pump has the optional o-ring sealing op
tion (available on 56C and 145TC frame pumps only),
in stall the o-ring (item 16) in the groove in the motor
adapter (motor end).
Carefully slide the pump onto the drive magnet as-
sembly. The last couple of inches (5 cm) before the
pump reaches the motor will have STRONG magnetic
attraction between the pump and outer drive magnet
assembly.
8. Secure the pump to the motor with (4) 3/8” bolts, lock
washers and flat washers (items 28, 29 & 30) using a
9/16” socket or wrench. Tighten to 240 in-lb (27.1
N-m). See figures 8 and 9.
