Blower Wheel Removal
When required, replace the blower wheel using the
following procedure:
1. Loosen blower pulley set screws and remove
the pulley using a wheel puller.
2. Remove the locking collar from the back bear-
ing (closest to the pulley) by loosening the set
screw and rotating the collar counterclockwise
(use punch to drive).
3. Press blower wheel out of the housing using a
wheel puller hooked to lugs on the bearing
housing. The bearings have been secured in
the housing with a retaining compound - Loc-
tite
®
RC/680, and considerable force will be
required to break this bond. After the bearings
have “broken loose” from the housing, only light
pressure should be required 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.
