2.
Install one bushing backup plate on the end of the hub and
secure with the supplied retaining ring. Repeat procedure
for other side.
3.
Place one bushing, flange end first, onto the driven shaft
and position per dimension "A", as shown in Table 1. This
will allow the bolts to be threaded into the bushing for
future bushing and reducer removal.
4.
Insert the output key in the shaft and bushing. For ease of
installation, rotate the driven shaft so that the shaft keyseat
is at the top position.
5.
Mount the reducer on the driven shaft and align the
shaft key with the reducer hub keyway. Maintain the
recommended minimum distance "A" from the shaft
bearing.
6.
Insert the screws, with washers installed, in the unthreaded
holes in the bushing flange and align with the threaded holes
in the bushing backup plate. If necessary, rotate the bushing
backup plate to align with the bushing screws. Tighten the
screws lightly. If the reducer must be positioned closer than
dimension "A", place the screws with washers installed,
in the unthreaded holes in the bushing before positioning
reducer making sure to maintain at least 3mm between the
screw heads and the bearing.

Place the second tapered bushing in position on the shaft
and align the bushing keyway with the shaft key. Align the
unthreaded holes in the bushing with the threaded holes in
the bushing backup plate. If necessary, rotate the bushing
backup plate to align with the bushing holes. Insert bushing

screws, with washers installed in the unthreaded holes in the
bushing. Tighten screws lightly.

Alternately and evenly tighten the screws in the bushing

nearest the equipment to the recommended torque given in
Table 1. Repeat procedure on outer bushing.

1.
One bushing assembly is required to mount the reducer
on the driven shaft. An assembly consists of one long
207
tapered bushing, one short tapered bushing, one tapered
232
bushing wedge, bushing screws and washers, two bushing
256
backup plates and retaining rings, and necessary shaft key
or keys. The driven shaft does not need to extend through
270
the reducer for the short shaft bushing to operate properly.
299
The minimum shaft length, as measured from the end of the
346
shaft to the outer edge of the bushing flange (see Figure 1),
is given in Table 1.
2.
The long bushing is designed to be installed from the side
of the reducer opposite the driven equipment as shown
A
in Figure 2. The long bushing when properly installed is
30
designed to capture the end of the customer shaft that does
30
not extend through the reducer. Normally the reducer would
be mounted such that the input shaft extends from the
36
side of the reducer opposite the driven equipment however
36
the reducer design allows installation of the reducer to be
36
mounted in the opposite direction.
48
3.
Install the tapered bushing wedge into the hollow bore of
the reducer from the same side as the long bushing will be
48
installed. When installing the tapered bushing wedge into
53
the reducer hub, install the flange end first so that the thin
53
taper is pointing outwards towards the long bushing as
shown in Figure 2. The wedge is properly installed when it
60
snaps into place in the reducer hub.

4.
Align the tapered bushing wedge keyway with the reducer
hub keyway. The keyway in the wedge is slightly wider than
the keyway in the reducer hub allowing for easier installation.
5.
Install one bushing backup plate on the end of the hub and
secure with the supplied retaining ring. Repeat procedure
for other side.
6.
Install the short bushing; flange first, on the driven shaft and
position per dimension "A", as shown in Table 1. This will
allow the bolts to be threaded into the bushing for future
bushing and reducer removal.
7.
Insert the output key in the shaft and bushing. For ease of
installation, rotate the driven shaft so that the shaft keyseat
is at the top position.
