Finish Thompson DB6, 6H, 7, 8, 9, 10 Series - Manual (Page 6)

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 using bolt, lock washer and
flat washer (items 21, 22, 23). 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 set screws (item 13B)
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 assembly. With the motor/outer
drive magnet assembly in a horizontal posi-
tion, securely clamp to the workbench.
Note: If the pump has the optional o-ring sealing option (available
on 56C and 145 frame pumps only), install the o-ring (item 12) in
the groove in the motor adapter (motor end).
Carefully slide the pump onto the drive magnet assembly. 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. See figure 8.
8. Secure the pump to the motor with (4) 3/8” bolts, lock washers
and flat washers (items 24, 25, 26). Tighten to 60 in-lb (6.8 N-m).
See figure 9.
Note: 63/71 frame require 3/8-16 hex jam nuts. Place nut in
and secure pump to motor.
Note: Apply anti-sieze compound on the threads of the bolts.
Tools Required:
Metric socket or wrench set, 9/16” socket or wrench and 3/16” Allen
Wrench (NEMA motors only)
1. Remove the pump, drive magnet assembly and hardware package
from the carton.
CAUTION: Keep away from metallic particles, tools and elec-
tronics. Drive magnets MUST be free of metal chips.
WARNING: Keep the drive magnet away from the open end of
the motor adapter and barrier. Strong magnetic attraction
could allow the drive hub to enter the motor adapter resulting
in injury or damage.
2. Place motor on the fan end. See figure 1.
NOTE: For 56C/145TC frame motors go to
step 4.
3. Install the motor adapter flange (item 14)
on motor face using bolts, lock washers
and flat washers (items 27, 28, 29). See
figure 2.
Torque bolts to the following:
· 63 frame (M5) = 30 in-lb (3.4 N-m)
· 71 frame (M6) = 90 in-lb (10.2 N-m)
· 80 frame (M6) = 90 in-lb (10.2 N-m)
NOTE: 63/71 B14 adapter flange is revers-
ible. Install 63/71 B14 adapter so that
proper motor flange size is facing motor.
NOTE: Apply anti-seize compound on the
threads of the bolts.
4. Coat the motor shaft with anti-seize com-
pound. Insert key supplied with motor into
keyway on motor shaft. See figure 3.
NOTE: Make sure the motor shaft is clean
and free of burrs. The outer drive is preci-
sion machined and has a bore tolerance of +.0005/-0 inch.
5. Slide the outer drive magnet assembly (item 13) onto the motor
shaft until the motor shaft contacts the snap ring in the bore of the
drive. See figures 4 & 5.

Unpacking and Inspection
Unpack the pump and examine for any signs of shipping damage. If
any damage is detected, save the packaging and notify the carrier
immediately.
