Split Taper Bushing
If the sprockets are made for split taper
bushings, follow these installation and
removal instructions:
5. How to install split taper bushing sprockets
Put the bushing loosely in the sprocket and start the capscrews.
Place the assembly on the shaft. Align both edges of the
sprocket with the edges of its mating sprocket (example: the
sprocket on the driven shaft).
Tighten the capscrews according to the instructions furnished
with the bushings.
6. How to remove split taper bushing sprockets
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 sprocket
has loosened.
Remove the sprocket/bushing assembly from the shaft.
Taper-Lock Bushing
The following instructions illustrate how
to install a sprocket made with a
taper-lock hub:
7. How to install a sprocket 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 sprocket with the edges of its
mating sprocket.
Tighten the screws alternately and evenly. This procedure will
wedge the bushing inward and cause it to contract evenly and
grip the shaft.
8. How to remove a sprocket 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.
