lowing procedure:

pulley using a wheel puller.
2. Remove the locking collar from the back bearing
(closest to the pulley) by loosening the set screw
and rotating the collar counterclockwise (use
punch to drive).

wheel puller hooked to lugs on the bearing hous-

and considerable force will be required to break
this bond. After the bearings have “broken loose”
from the housing, only light pressure should be re-
quired to remove the wheel assembly out of the
housing.
NOTE: It may or may not be possible to remove
the front bearing from the blower wheel without
damaging it. If the bearing is damaged, it will need
to be replaced along with the wheel.
