JR
— Thread the bushing nut onto the hollow shaft one
to two turns .
NOTE: The bushing nut threads have been coated with
an anti-seize compound at the Factory . This compound
should not be removed . Before re-installing a previously
used nut, re-coat the nut threads only with an anti-seize
compound .
NOTE: In extremely severe or corrosive environments,
additional anti-seize compound MUST be applied to the
threads of the TA bushing nut .
WARNING
: DO NOT apply anti-seize or lubricant
to bushing or shaft surfaces. Use of anti-seize may
prevent secure connection of the drive to the shaft and
cause the drive to move.
WARNING
: Overtightening can fail the internal retaining
ring. (See Appendix G, for listing of retaining rings).
DO NOT apply ANTI-SEIZE
on these areas.
a .
PREFERRED METHOD
— Use a spanner, chain
or pipe wrench to tighten the bushing nut to the
torque value indicated in Table 6 . Apply Loctite
243 or equivalent to threads of setscrews . Tighten
the setscrew on the bushing nut to 19 lb-ft (26 Nm)
torque .
b .
ALTERNATE METHOD (TO BE USED WHEN
EXACT TORQUE CAN NOT BE MEASURED)
—
Use a spanner (Table 6), chain or pipe wrench to
tighten the bushing nut just until the drive can no
longer be moved by hand axially on the driven shaft .
Loosen nut ONLY until it can be turned by hand but
do not unseat the taper . Retighten the nut hand tight .
Now mark a spot on the bushing nut . Next mark a
spot on the driven shaft 180° from the first mark . Use
the spanner wrench to tighten the nut until the two
marks are aligned i .e ., one half turn . Apply Loctite
243 or equivalent to threads of setscrews . Tighten
the setscrew on the bushing nut to 19 lb-ft (26 Nm)
torque .

These are chain wrenches where standard spanner wrenches are not
available .

JR
— Install backstop, motor mount, motor, sheaves
(mount sheaves as close to the drive and motor
housing as possible), belts and guard . Refer to
Appendix D for motor mount installation instructions .
Proceed to Step 13 .
11 .
JF
(USING TAPERED DRIVE SHAFT)
— Put key into
the driven shaft . Lift drive into position and slide onto
the driven shaft taking care that the driven shaft key
seats into the hollow shaft keyway . DO NOT hammer or
use excessive force . Secure the drive to the foundation
with fasteners using torque values shown in Table 7 .
Next, secure the drive to the shaft with the thrust plate
fastener . Refer to Table 8 for torque value . Reinstall the
hollow shaft cover . Install motor mount, motor, sheaves,
belts and guard . Refer to Appendix D for motor mount
installation instructions . Proceed to Step 14 .
12 .
JSC (5407 ONLY)
— Assemble drive to trough and
install drive shaft coupling bolts per screw conveyor
manufacturer’s instructions . Install motor mount, motor,
sheaves, belts and guard . Refer to Appendix D for motor
mount installation instructions . Proceed to Step 14 .
13 .
JR
— When the torque arm turnbuckle is used for belt
tension adjustment, position the motor so that the belt
pull will be about 90° to a line through the drive input
shaft and hollow shaft as shown in Figure 9 . For drives
where the motor is moved to adjust belt tension, mount
the motor slide base so that the belt tension adjustment
is approximately parallel to the belt centers . Refer to
Appendix D, for instructions relative to alignment of
sheaves and belts . Proceed to Step 14 .
