Step 4. Remove the blower wheel.
Once the set screw is loosened, pull the blower wheel downward slightly, then gently remove
the blower wheel from shaft. Use caution to avoid bending or distorting the blower wheel
and take care not to move or lose the metal balancing clips that may be affixed to the blower
wheel. If the blower wheel is difficult to remove, the area where the motor shaft makes
contact with the blower wheel hub may need to be sprayed with a common penetrating oil
such as WD-40
®
and allowed to soak for a short time.
