TAPER BUSHING
— With the driven shaft keyway at the
12 o’clock position, slide bushing assembly onto the driven
shaft, nut end first, and position the keyway slot over the
shaft keyway. The bushing may have to be opened slightly
to assist in installation. Insert a screwdriver into the slot
in the bushing and very lightly pry open until the bushing
slides onto the shaft. Insert the drive key furnished with
the bushing into the shaft keyway. On drives using the
thrust plate kit, slide the bushing assembly onto the driven
shaft until final position (end of driven shaft open ended
keyway).
Installation of Shaft-Mounted Drives
Sizes M1130 - M1190
1. On drives using the thrust plate kit, remove the hollow
low speed shaft cover. Before lifting the drive into
position, rotate the high-speed shaft until the hollow
shaft keyway will be in position to line-up with the driven
shaft key.
2. Lift the 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.
3. 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, recoat the nut threads only with an anti-seize
compound.
NOTE: In extremely severe or corrosive environments,
additonal 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.
See Table 12 for nut setscrew and wrench sizes.

PREFERRED METHOD
— Use a spanner, chain
or pipe wrench to tighten the bushing nut to the

† The minimum engagement is necessary for full bushing engagement;
the maximum engagement is only if a thrust plate will be employed to
remove the drive from the driven shaft. Shaft engagements include
5 mm (.20 inch) clearance at the bushing nut.
