Split Taper Bushing
If the sheaves are made for split taper
bushings, follow these installation and
removal instructions:
5. How to install split taper bushing sheaves
Put the bushing loosely in the sheave and start the capscrews.
Place the assembly on the shaft. Align both edges of the sheave
with the edges of its mating sheave (example: the sheave on
the driven shaft).
Tighten the capscrews according to the instructions furnished
with the bushings.
6. How to remove split taper bushing sheaves
Remove all capscrews.
Put two of the capscrews in the tapped holes in the flange of
the bushing.
Turn the bolts alternately and evenly until the sheave
has loosened.
Remove the sheave/flange assembly from the shaft.

Bushing
If the sheaves are made with a QD® hub,
follow these installation and
removal instructions:
3. How to install a sheave with a QD® hub
Insert the bushing in the hub and line up bolt holes.
Insert the pull-up bolts and turn until finger tight.
Hold the loosely-assembled unit so the bushing flange points
toward the shaft bearings. Reverse mounting the QD® bushing
can be advantageous for some applications.
Slip the unit onto the shaft and align the hub in the
desired position.
Tighten the setscrew in the flange only enough to hold the
assembly in position.
Tighten each pull-up bolt alternately and evenly.
Recheck alignment and completely tighten the setscrew on
the shaft.
4. How to remove a sheave with a QD® hub
Place two of the pull-up bolts in the tapped holes in the sheave.
Turn the bolts alternately and evenly. They will push against the
bushing flange and act as jackscrews to break the grip between
the bushing and the tub.
