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 easy 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 3.0mm between the screw
heads and the bearing.
7. 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.
8. 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.
Short Shaft Bushings
1. One bushing assembly is required to mount the reducer on
the driven shaft. An assembly consists of one long tapered
bushing, one short tapered bushing, one tapered bushing
wedge, bushing screws and washers, two bushing backup
plates and retaining rings, and necessary shaft key or keys.
The driven shaft does not need to extend through the reducer
for the short shaft bushing to operate properly. The minimum
shaft length, as measured from the end of the shaft to the
outer edge of the bushing flange (see Figure 5), 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 in Figure
6. The long bushing when properly installed is designed to
capture the end of the customer shaft that does not extend
through the reducer. Normally the reducer would be mounted
such that the input shaft extends from the side of the reducer
opposite the driven equipment however the reducer design
allows installation of the reducer to be mounted in the
opposite direction.
3. Install the tapered bushing wedge into the hollow bore of
the reducer from the same side as the long bushing will be
installed. When installing the tapered bushing wedge into the
reducer hub, install the flange end first so that the thin taper
is pointing outwards towards the long bushing as shown in
Figure 6. The wedge is properly installed when it snaps into
place in the reducer hub.
