Flange Bearing Removal (Fig. 8)
1. Remove drive belt and pulley from shaft (refer to ser-
vice information for specific drive assembly that exists
later in this section).
2. Loosen three (3) set screws that secure flange bear-
ing collar to shaft.
3. Note location of grease fitting so bearing can be
properly orientated during installation.
4. Remove four (4) lock nuts, flat washers and screws
that secure bearing to machine frame.
5. Slide flange bearing from shaft.
Flange Bearing Installation (Fig. 8)
1. Thoroughly clean shaft surface. If necessary, re-
move nicks or burrs on shaft with emery cloth or fine file.
2. Lubricate the shaft surface with light oil.
3. Slide bearing onto shaft. Position bearing so grease
fitting is properly orientated.
4. Tighten three (3) set screws in bearing so that they
are finger tight. Bearing should slide on shaft with some
resistance.
5. Secure bearing to machine frame with removed fas-
teners.
6. Position the bearing collar so that a set screw is di-
rectly opposite the split in the sleeve (Fig. 9). Tighten
three (3) bearing set screws using the following steps:
A. Starting with the set screw that is opposite from
the split in the sleeve, tighten set screws 1/4 turn.
B. Again, starting with the set screw that is opposite
from the split in the sleeve, tighten set screws an
additional 1/4 turn.
C. Finally, starting with the set screw that is opposite
from the split in the sleeve, torque set screws 66 in- -
lb (7.5 N- -m).
NOTE: A replacement flange bearing includes an allen
wrench and torque indicator that can be used to properly
torque bearing set screws (Fig. 9). When tightening set
screws, the torque is correct when the long end of the
allen wrench contacts the torque indicator.
7. Install pulley and drive belt to shaft (refer to service
information for specific drive assembly that exists later
in this section).
