6. Insert screws through the unthreaded holes in the
tapered bushing flange and align with the threaded
holes in the backup plate. Tighten the screws slightly.
7. Place the second tapered bushing in position on the
shaft and align the bushing with the shaft key. Align
unthreaded holes in the bushing with the threaded
holes in the backup plate. Insert bushing screws and
tighten slightly.
8. Alternately and evenly tighten the screws in the
bushing nearest to the driven equipment first. Torque
the screws evenly, a small amount at a time, to the
recommended torque wrench settings shown in the
table. Repeat with the outer bushing.
NOTE: The bushing bolts must not protrude through
the backup plate, as output seal damage may result. If,
while tightening the bushing bolts, it appears that the
bolts are starting to protrude through the backup plate,
remove the bolts and install the appropriate size flat
washer between the lockwasher and the tapered
bushing flange on each bolt.

TWIN TAPERED BUSHING REMOVAL
1. Remove bushing screws.
2. Clean and lubricate the bushing screws and the
threaded jackscrew holes in the tapered bushing
flange. Install bushing screws in those threaded holes.
Tighten the screws alternately and evenly until the
bushings are free from the shaft.
3. If the reducer is too close to the driven to install the
jacking screws, first loosen but do not remove the
outer bushing. Then loosen the inner bushing screws
as far as possible. Use two wedges spaced 180
degrees between the backup plate and the bushing
flange. Drive the wedges in alternately until the
bushing is free from the shaft.

STRAIGHT BORE BUSHING INSTALLATION
Mount the reducer on the driven shaft. If bushings are
used, assemble the bushings in reducer first. A set of
bushings for one reducer consists of one key-seated
(drive) bushing and one plain (solid) bushing. The user's
driven shaft must extend through the full length of the
speed reducer. The location of the setscrews and key(s)
is shown in the chart and diagram below. Shaft collars are
used on the C150 & C262 only. The C200 & C350 do not
require shaft collars as there is sufficient thread engage-
ment for the setscrews in the hollowshaft.
NOTE: All keys are secured with setscrews.
NOTE: Two setscrews are used in each end. The third
hole in the hollow shaft is for user convenience in removing
the speed reducer from the driven shaft with use of a gear/
bearing puller. Also, it is sometimes more accessible than
trying to rotate the shaft to insert the required setscrews.
Place the output flange/brackets on the conveyor mount-
ing surface using customer supplied mounting hardware.
Tighten hardware sufficiently to hold output flange/bracket
in place, but realize that final alignment (stated below)
must be completed after all elements are installed.
Install the reducer on the shaft a sufficient distance from
-------
the conveyor side plate to allow access to bushing set-
screws. Tighten all setscrews to 150 in lb torque.
L
Attach output/bracket flange and reducer together using
(Min.)
mounting hardware provided. Tighten hardware sufficiently
7.91
to hold reducer in place, but not tight. This will allow
8.81
reducer to find it's own center of alignment by doing the
9.81
final alignment.
12.00
Final alignment should be accomplished by running the
conveyor/reducer (unloaded) and observing the reaction of
the output flange/bracket. If the output flange/bracket
appears to be in a bind, turn power off, stop unit, loosen
the output flange/bracket mounting hardware on the
reducer, and run the unit again to allow reducer to find it's
own center of alignment. When it is evident the flange is
no longer in a bind, tighten output flange/bracket mounting
hardware to the recommended torque.
NOTE: Do not loosen hollowshaft setscrews when
making final adjustment.
