6. Remove four (4) socket head screws and lock wash-
ers that secure drive and rear end brackets to stator as-
sembly. Remove end brackets from stator.
NOTE: After the traction motor has been disas-
sembled, it is recommended that a new rear end bracket
bearing be installed. Although the bearing may appear
and feel in good condition, the bearing could be "bri-
nelled" (races or balls deformed). After assembly with a
questionable bearing, the motor may exhibit noise and
vibration problems or fail within a relatively short period
of service.
7. Remove the retaining ring from the rear end bracket
(Fig. 50). Press bearing from the rear end bracket and
discard the removed bearing.
CAUTION
When using compressed air for cleaning motor
components, follow all safety instructions, in-
cluding wearing eye and respiratory protection.
8. Carefully blow out any accumulated debris from the
stator and the armature using clean, oil free, com-
pressed air.
9. Inspect traction motor armature and transaxle input
shaft splines for wear or damage. Replace motor and/or
transaxle input shaft if spline damage is found.
10.Visually inspect the armature and stator compo-
nents. If damage to either of these components is found,
replace traction motor.
Motor Assembly (Fig. 47)
1. Make sure that all traction motor components are
clean and in good condition before assembling the mo-
tor.
IMPORTANT: To prevent bearing damage when
installing new bearing in the rear end bracket, sup-
port end bracket and press only against the bearing
outer race.
2. Press a new bearing into the rear end bracket, press-
ing on the bearing outer race only. Secure bearing in
bracket with retaining ring (Fig. 50). Make sure that re-
taining ring is fully seated in groove in bracket after as-
sembly.
3. Position drive and rear end brackets to stator assem-
bly using notes made during disassembly to properly
align drainage slots in brackets and stator (Fig. 49).
