(clips) on blower wheel vanes. Do not bend wheel or blades
as balance will be affected.

7. If greasy residue is present on blower wheel, remove wheel

from the blower housing and wash it with an appropriate
degreaser. To remove wheel:

NOTE

: The DIBC composite wheel used in some models should

be cleaned with mild soapy water only. Allow wheel to dry prior to

reassembly.

a. Mark blower wheel location on shaft before disassembly

to ensure proper reassembly.

b. Loosen setscrew holding blower wheel on motor shaft.

NOTE:

Mark blower mounting arms and blower housing so each

arm is positioned at the same hole location during reassembly.

c. Mark blower wheel orientation and cutoff plate location to

ensure proper reassembly.

d. Remove screws securing cutoff plate and remove cutoff

plate from housing.

e. Remove bolts holding motor mounts to blower housing

and slide motor and mounts out of housing.

f. Remove blower wheel from housing.

g. Clean wheel per instructions on degreaser cleaner. Do not

get degreaser in motor.

8. Reassemble motor and blower wheel by reversing items 7b

through 7f. Ensure wheel is positioned for proper rotation.

9. Torque motor mounting bolts to 40 +/-- 10 lb--in. when re-

assembling.

NOTE

: Ensure that the removable inlet ring is installed before the

motor on furnaces with a DIBC composite blower.

10. Torque blower wheel set screw to 160 +/-- 20 lb--in. when

reassembling.

11. Verify that blower wheel is centered in blower housing and

set screw contacts the flat portion of the motor shaft. Loosen
set screw on blower wheel and reposition if necessary.

12. Spin the blower wheel by hand to verify that the wheel does

not rub on the housing.

13. Reinstall blower assembly in furnace.
14. Reinstall 2 screws securing blower assembly to blower

deck.

15. Reconnect blower leads to furnace control. Refer to furnace

wiring diagram, and connect thermostat leads if previously

disconnected.

NOTE:

Be sure to attach ground wire and reconnect blower

harness plugs to blower motor.
