INSTALLATION GUIDE
Split Taper Bushing
If the sheaves are made for split taper bushings, follow these
installation and removal instructions.
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 (i.e. the sheave
on the driven shaft).
Tighten the capscrews according to the instructions
furnished with the bushings.
HOW TO REMOVE SPLIT TAPER BUSHING SHEAVES
Remove all capscrews.
Put two of the capscrews in the tapped holes in the fange of
the bushing.
Turn the bolts alternately and evenly until the sheave has
loosened.
Remove the sheave/fange assembly from the shaft.
Taper-Lock Bushing
HOW TO INSTALL A SHEAVE MADE
WITH A TAPER-LOCK HUB
Look at the bushing and the hub. Each has a set of half-holes. The
threaded holes in the hub are the mates to the non-threaded holes
in the bushing.
Insert the bushing in the hub and slide it onto the shaft. Align a
threaded hub hole with non-threaded bushing hole.
Start the setscrews into the holes that are threaded in the hub only.
Do not tighten the setscrews yet.
Align both edges of the sheave with the edges of its mating sheave.
Tighten the screws alternately and evenly. This procedure will
wedge the bushing inward and cause it to contract evenly and grip
the shaft.
HOW TO REMOVE A SHEAVE MADE
WITH A TAPER-LOCK HUB
Remove all the setscrews.
Place two of the setscrews in the holes that are threaded in the
bushing only.
Turn the setscrews alternately and evenly. This movement will
unlock the grip and permit easy removal of the assembly with no
shock to the bearings or machinery.

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 fange and act as jackscrews to break the grip
between the bushing and the hub.
