B. Slide the end cap/shaft assembly from the
bearing (Figure 75). If, upon your inspection,
noticeable wobble exists between the end cap/
shaft assembly and the bearing, both should
be replaced.
Figure 75 0217-047
Note: Often if the bearing should seize, heat is
generated. The heat will cause the bearing and shaft
to become blue in color. Again, both the end cap/shaft
assembly and bearing should be replaced.
C. To remove the bearing from the L. H. side
plate, drill out three pop rivets retaining the
bearing in the bearing retainer or flange (Figure
75). Replace the bearing and the bearing
retainer. Use pop rivets (Toro P.N. 3292-7) to
reassemble.
Note: A pop rivet gun can be obtained through
many hardware stores in your area.
D. Replace the end cap/shaft assembly.
6. Assemble rotor halves. To locate the rotor halves
into the correct position in the end plates, loosely
install the four self-tapping location screws (Figure
73).
7. Assemble both paddles to the rotor halves.
Torque each screw 15 in·lbs (Figure 76). Lastly,
tighten the four self-tapping rotor location screws.
(CAUTION: Do not overtorque screws, the
threads may be damaged.)
Figure 76 0217-048
8. Replace rotor pulley. Be certain to replace both
the spacer and washer, before turning the rotor
pulley onto the shaft (counterclockwise). Tighten
the rotor pulley finger tight (Figure 72). The
rotation of the pulley during the operation of the
unit will tighten the pulley to the proper torque.
9. Replace belt. Refer to "Replacing Drive Belt" on
page 5 - 1. Complete steps 5 through 7.
