lower, until dial indicator shows that internal assem-
bly has bottomed, Figure 109.
f. The reading obtained on dial indicator
represents converter end clearance. If clearance is
less than .050", the converter is acceptable . If clear-
ance is .050" or more, replace the converter.
5 . If fluid in the converter has the appearance of
having been mixed with "aluminum paint", con-
verter is damaged internally and must be replaced .
6. Do not change the converter if some other part
of the transmission has resulted in the converter con-
taining dark, discolored fluid. The full flow filter is
designed to remove all harmful residue from non-
conforming parts, other than converter and/or
pump non-conformities before the oil is pumped into
the converter.
7. Check the converter internally for damage to
its roller bearings, thrust races, and the roller clutch,
Figure 110.
a. The thrust roller bearings and thrust races
can be checked by viewing them when looking into
the converter neck or feeling through the opening to
make sure they are not cracked, broken, or misposi-
tioned.
b. The stator roller clutch can be checked by
inserting a finger into the splined inner race of the
roller clutch and trying to turn the race in both
directions . The inner race should turn freely in the
clockwise direction, but not turn, or should be very
difficult to turn, in the counterclockwise directions .
IMPORTANT :
Do not use such items as the pump
cover or stator shaft to turn the race as the re-
sults may be misleading .
8 . Check for stripped converter bolt holes. If
found stripped, inspect for cause (such as damaged
TRANSMISSION 7- 7 3
bolt threads), heli-coil the damaged bolt holes and
install new bolt(s).
INSTALL TORQUE CONVERTER
1 . Position transmission jack to transmission and
install transmission on jack using safety chain.
2. Carefully position converter on turbine shaft,
making certain converter is properly aligned. Long
screws or eyebolts can be threaded into the weld nuts
on the converter and used as handles.
3 . Rotate converter until the shafts are piloted
and the converter lugs are indexed in the pump gear .
4. If difficulty is experienced in alignment, tap on
outer diameter of converter with plastic-headed
hammer, while turning converter.
5 . Install Converter Holding Clamp, J-21366, on
transmission case .
6 . Remove two (2) 8" bolts from case to engine
mounting face, Figure 20 .
INSTALLING FINAL DRIVE
(FIGURE 19)
1 . Install new gasket, on final drive, after first
soaking with transmission fluid.
2 . Align final drive to transmission and secure
with bolts "B, C, E, F, G" and nut "H", torque to
25 ft .-lbs.
3 . Install new O-ring on filler tube assembly and
assembly to final drive . Torque bolt "A" to 25 ft .-lbs.
NOTE:
Install transmission and final drive in
vehicle as described earlier in this section .
