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).
a
PREFERRED METHOD —
Use a spanner (Table 6),
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 setscrew Tighten
the setscrew on the bushing nut to torque value
indicated in Table 6A
b
ALTERNATE METHOD —
(To be used when torque
cannot 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 top of the driven shaft Next mark a spot on
the bushing nut 180° from the driven shaft mark
(90°CCW for sizes 5107 & 5115) Use the spanner
wrench to tighten the nut CW one half turn until the
two marks are aligned (one quarter turn for sizes
5107 & 5115) Apply Loctite 243 or equivalent to
threads of setscrew Tighten the setscrew on the
bushing nut to torque value indicated in Table 6A

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 14
12
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 shaft
with the thrust plate fastener Refer to Table 3 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 15
DO NOT apply ANTI-SEIZE
on these areas.
