68 TECHNICAL SERVICE MANUAL
CAUTION: The feeler gauge must be flat against
the thrust washer to obtain an accurate reading.
Compare measurement found with feeler gauge with the
chart in Figure 38 to determine the correct selective spacer
washer to use. For example: if measurement is found to be
.067", a number 6 selective spacer washer should be used
when transmission is reassembled. Check the number on the
original spacer (which was removed from the transmission).
It should be the same as the number found on the chart. If
not, a new spacer must be used for reassem bly. The identification
number of the required spacer should be recorded
so that it can be obtained for assembly.
Remove Truarc snap ring, sun gear with bronze and steel
thrust washers, internal gear with steel and bronze thrust
washers, and .070" selective spacer washer.
Remove gauge, sun gear with bronze and steel thrust
washers, internal gear, with steel and bronze thrust washers,
and .070" selective spacer washer.
FRONT UNIT COUPLING, PRESSURE
REGULATOR, AND COOLER
ADAPTER REMOVAL
Rotate transmission to horizontal position with oil pan "up."
Remove front unit coupling assembly from transmission
case and remove oil cooler adapter attaching screws and
adapter with gasket from side of transmission case. Remove
two oil cooler sleeves and seals by pulling from case (Fig.
41).
Special Tool Method
Assemble parts as outlined in the first five paragraphs listed
under "Feeler Gauge Method."
Place front unit end play checking gauge J-6282 over
intermediate shaft with splined end of inner sleeve facing
down. The outer sleeve of tool will rest on front unit sun
gear bronze thrust washer and the splines of the inner sleeve
will rest against the bottom edge of the groove from which
the clearance is measured (Fig.,40). It will be noted that the
inner sleeve now projects above the outer sleeve.
Place the front unit selective spacer washer, which was
removed from the transmission, over the inner sleeve of
gauge J-6282. When the washer lies flat on the outer sleeve,
the top of it should be flush with the top of the inner sleeve.
If it is not flush, select a washer which is flush and install
the new washer when the transmission is assembled (Fig.
40).
