Blower Wheel Removal<br />
Wheel Puller<br />
Hooked to Lugs<br />
on Bearing Housing<br />
When required, replace the blower wheel using the<br />
following procedure:<br />
1. Loosen blower pulley set screws and remove<br />
the pulley using a wheel puller.<br />
2. Remove the locking collar from the back bearing<br />
(closest to the pulley) by loosening the set<br />
screw and rotating the collar counterclockwise<br />
(use punch to drive).<br />
3. Press blower wheel out of the housing using a<br />
wheel puller hooked to lugs on the bearing housing.<br />
The bearings have been secured in the<br />
housing with a retaining compound - Loctite ®<br />
RC/680, and considerable force will be required<br />
to break this bond. After the bearings<br />
have “broken loose” from the housing, only light<br />
pressure should be required to remove the<br />
wheel assembly out of the housing.<br />
NOTE: It may or may not be possible to remove<br />
the front bearing from the blower wheel without<br />
damaging it. If the bearing is damaged, it will<br />
need to be replaced along with the wheel.<br />
Pressing Blower Wheel Out of Housing<br />
Blower Wheel Installation<br />
1. To install the blower wheel, reverse the removal<br />
procedures. The front bearing is mounted<br />
on the blower wheel shaft, secured by a locking<br />
collar. Drive the locking collar clockwise with a<br />
punch, and tighten the set screw.<br />
2. Press blower wheel and front bearing into the<br />
blower housing. Use Loctite ® RC/680 retaining<br />
compound on the outer bearing race and inside<br />
the bearing housing.<br />
3. Press the rear bearing into place, using Loctite ®<br />
on both the outer bearing race and the housing.<br />
4. Install the locking collar on the rear bearing and<br />
install the blower pulley to complete the blower<br />
assembly. Torque the blower pulley set screws<br />
to 250 in-lb (28.3 N⋅m).<br />
