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 hous-
ing. The bearings have been secured in the housing with a retaining compound - Loctite® RC/680, and considerable force will be re- quired 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.
