STATOR/ROTOR REMOVAL AND REPLACEMENT PROCEDURE
BLOWER
SEGMENT (4)
ROTOR
PROCEDURE
1. Remove the screws and disc clamping bars
from the rotor coupling disc, and remove the
rotor.
NOTE: earlier machines used three 0.31" thick
clamping bars and later models use six 0.14" thick
clamping bars arranged in three sets of two bars
each.
If the rotor is to be replaced, remove the screws,
rotor clamping ring and coupling disc from the rotor
hub.
Replacing the Rotor
1. Whenever the rotor and stator are separated, it
is highly recommended that a new bearing and
tolerance ring be installed when the rotor and
stator are reassembled.
2. Examine the rotor, coupling disc, clamping ring,
clamping bars, screws, lock washers, and the
engine flywheel. Make sure that all of the parts
are clean and in good condition.
3. Install a new bearing on the rotor shaft.

4. Assemble the coupling disc and clamping ring
to the rotor hub. The surface of the disc with
the stamping burrs should be against the rotor
hub. The side of the clamping ring with the
radius should be placed against the coupling
disc. See Figure F.29.
5. Insert the screws with lock washers and evenly
tighten to a torque of 17 to 19 Ft-Lbs.
6. Lift the rotor assembly with the hoist and lifting
straps and recheck the engine flywheel and
coupling disk for anything that might prevent
proper seating.
7. To attach the coupling disk to the engine fly-
wheel, align the screw holes and insert the six
screws, with lock washers, through the disc
clamping bars and the coupling disc and into
the engine flywheel.
8. Evenly tighten all the screws to a torque of 17 to
19 Ft-Lbs.
