When replacing bearings refer to the manufacturers
installation instructions included with the bearing.
Typical Procedure For Changing The Shaft And
Bearings
1. Remove protective shaft coating.
2. Remove the drive side sheave.
3. Disconnect the grease lines from the existing
bearings.
4. Identify the total shim thickness at each bearing
and mark the bearing mount for future reference.
5. Remove mounting bolts for bearings and remove
any shims.
6. Loosen bearing and blower wheel shaft setscrews.
7. Remove the shaft from the unit by sliding the
bearings and blower wheels along the shaft as
the shaft is extracted. Unless a blower wheel is
damaged, it should be unnecessary to remove the
blower wheel from the blower housing.
8. Slide the new shaft through the
fi
rst blower wheel
hub.
9. Once the shaft is completely through the
fi
rst
blower wheel, slide a bearing onto this end of the
shaft.
10. Slide the shaft through the next blower wheel hub
and add another bearing. Continue this procedure
until the shaft is through all of the blower wheels.
11. Place a bearing on each end of the shaft.
12. Replace the old shims with new.
13. Bolt the bearings in place and reattach the grease
lines. (When installing a Sleevlock bearing see note
at bottom of page).
14. Adjust the shaft so the blower hub keyways are in
the middle of the shaft keyways.
15. Adjust the shaft so it protrudes past the non-drive
end bearing, the blower sheave keyway mates with
the shaft keyway, and the drive side sheave can be
aligned with the motor sheave. Ideally, the blower
sheave should be as close to the drive side bearing
as possible, the motor sheave should be as close
to the motor housing as possible, and the belts
should be straight.
16. Be sure the shaft does not rub on or interfere with
the closing of the access door.
17. Align all bearing setscrews, so that the same set
screw on each bearing is pointed in the same
direction as the other bearings’ setscrews.
18. Place a drop of “BLUE” Loctite on the bearing
setscrews and tighten all of the setscrews. Follow
the mounting instruction’s procedure on the inside
of the bearing box, for the proper tightening and
torque values.
19. Align the blower hubs’ keyway with those in the
shaft. Be sure the clearance between the blower
wheel and blower housing is the same on each
side.
20. Rotate the shaft by hand to insure free operation.
Correct any rubbing of the blowers on the
housings.
21. Place a drop of “BLUE” Loctite on the blower set-
screws and tighten all of the setscrews.
22. Align the blower and motor sheaves using a laser
or straight edge and tighten the blower sheave to
the shaft.
23. Replace the belts and tighten the motor base
adjustment for the proper belt tension. Over
tightening the belt tension will severely reduce
belt and bearing life. Belt de
fl
ection should be
approximately 1/64 inch of the belt span.
