SPLIT-TAPER BUSHING
TAPER-LOCK BUSHING
Thoroughly clean all the surfaces of the bushing, sheave and
motor shaft. Install the sheave & bushing on the shaft in the
orientation shown. Verify proper key is installed. Install bushing
hardware through the sheave, threading into the bushing
hand-tight. Level the top surfaces of the sheaves while
maintaining full engagement of the shafts through the bushing
bores. Use the bushing set screws to hold in place while
adjusting level.
Refer to belt installation details on following
pages for leveling instructions
. When leveling is complete,
torque bushing cap screws per table. Values are for aluminum
sheaves only. If sheave is cast iron, use the torque value
supplied with the bushing.
Do not apply, oil, grease, anti-seize compounds, or other
substances on the bushing, sheave, or shaft surfaces. Do not
force bushing onto the shaft, or sheave onto bushing. Do not
spread the bushing
.
Do not attempt to pull the bushing flange
flush to the sheave. A clearance gap is normal.

BUSHING TYPE
Thoroughly clean all the surfaces of the bushing, sheave and
motor shaft. Install the sheave & bushing on the shaft in the
orientation shown. Verify proper key is installed. Install bushing
set screws. Alternately torque the scres until the sheave and
bushing tapers are seated together. Level the top surfaces of
the fan & motor sheaves while maintaining full engagement of
the shafts through the bushing bores.
Refer to belt installation
details on following pages for leveling instructions
. When
leveling is complete, torque bushing set screws per instructions
supplied with the bushing. Tap the face of the bushing using a
block or sleeve to prevent damage. This will ensure that the
bushing is squarely seated in the shreave bore. Repeat torquing
of set screws per instructions supplied with the bushing.
Recheck set screw torque after initial drive run-in and periodically
thereafter.
Do not apply, oil, grease, anti-seize compounds, or other
substances on the bushing, sheave, or shaft surfaces. Do not
force bushing onto the shaft, or sheave onto bushing. Do not
spread the bushing
