TRANSMISSION-TORQUEFLITE
Disassembly
(1) Remove the thrust washer from the forward
end of the output shaft (Fig. 104).
(2) Remove the selective snap ring from the for-
ward end of the output shaft, then slide the front
planetary assembly
off
the shaft.
(3) Slide the front annulus gear off the planetary
gear set (Fig. 104). Remove the thrust washer from
the rear side of the planetary gear set.
(4) Slide the sun gear, driving shell and the rear
planetary assembly
off
the output shaft.
(5)
Lift the sun gear and driving shell
off
the rear
planetary gear assembly. Remove the thrust washer
from inside the driving shell. Remove snap ring and
steel washer from the sun gear (rear side of driving
shell) and slide the sun gear out of the shell. Remove
the front snap ring from the sun gear if necessary.
Note that the front end of the sun gear
is
longer than
the rear.
(6) Remove the thrust washer from the forward
side of the
rear
planetary gear assembly, remove the
planetary gear set from the rear annulus gear.
Inspect ion
Inspect the bearing surfaces on the output shaft
for nicks, burrs, scores or other damage. Light
scratches, small nicks or burrs can be removed with
crocus cloth or a fine stone. Inspect the speedometer
drive gear for any nicks or burrs, and remove with
a sharp edged stone. Make sure all oil passages in
the shaft are open and clean.
Inspect bushings in the sun gear for wear or
scores, replace the sun gear assembly if bushings are
damaged. Inspect all the thrust washers for wear and
scores, replace if damaged or worn below specifica-
tions. Inspect the thrust faces of the planetary gear
carriers for wear, scores or other damage, replace as
required. Inspect the planetary gear carrier for
cracks and pinions for broken or worn gear teeth and
for broken pinion shaft lock pins. Inspect the annulus
gear and driving gear teeth for damage. Replace dis-
torted lock rings.
Assembly
Refer to Figure 104 for parts reference.
(1) Position the rear planetary gear assembly in
the rear annulus gear. Place the thrust washer on the
front side of the planetary gear assembly.
(2) Insert the output shaft in the rear opening of
the rear annulus gear. Carefully work the shaft
through the annulus gear and planetary gear assem-
bly. Make sure the shaft splines are fully engaged in
splines of the annulus gear.
(3) Install the snap ring in the front groove of the
sun gear (long end of gear). Insert the sun gear
through the front side
of
the driving shell, install the
rear steel washer and snap ring.
(4)
Carefully slide the driving shell and sun gear
assembly on the output shaft, engaging the sun gear
teeth with the rear planetary pinion teeth. Place the
thrust washer inside the front driving shell.
( 5 )
Place the thrust washer on the rear hub of the
front planetary gear set, then slide the assembly into
the front annulus gear.
(6) Carefully work the front planetary and annulus
gear assembly on the output shaft, meshing the plan-
etary pinions with the sun gear teeth.
(7) With all components properly positioned, in-
stall selective snap ring on front end of the output
shaft. Re-measure the end play of the assembly.
NOTE:
The clearance can
be
adjusted by the use of
various thickness snap rings. Snap rings are avail-
able in
.048-.052, .055-.OS9
and 362-.066 inch thick-
ness.
OVERRUNNING CLUTCH
Inspection
Inspect the clutch rollers for smooth round
sur-
faces, they must be free of flat spots and chipped
edges. Inspect the roller contacting surfaces in the
cam and race for brinelling. Inspect the roller springs
for distortion, wear or other damage.
A-727-A and
B:
Inspect the cam set screw for tight-
ness. If loose, tighten and restake the case around
the screw.
Overrunning Clutch Cam Replacement-
A-904-G and A-904-LA
If the overrunning clutch cam or spring retainer
are found damaged, they can be replaced with a serv-
ice replacement cam, spring retainer, and retaining
bolts (Fig.
105).
