"L"
indicates the effective length of the torque
wrench. In the case of the torque wrench expressed
in _the m-kg unit, measure the
..L"
in terms bf ,*,
and substitute the value (for example, 30 in case of
30 cm) into formula (1). In the case of the ft-lb
torque wrench, on the other hand, measure the ..L"
in the inch unit, .trd substitute the value into for-
mula (2). The prescribed tightening torque will thus
be obtained.

7A-I. INSTALLATION AND ADJUSTMENT OF
TRANSMISSION
.. Before installing the transmission, measure the run-
rut of the torque converter drive pla'te with a dial
a3uge. The runout must be within 0.3 mm (0.012
n). In case the runout exceeds 0.5 mm (0.020 in),
':place the drive plate.
- \l/hen combining the converter with oil pump, check
"irether they are rightly combined with each other
-'. measuring the distance shown in
Fig. 7A-56. The
:-stance is approximately 19.5 mm (0.78 inl. If there
, great difference in the measurement, the converter
.-.ould be rightly combined again.
Fig. 7A-56 Checking torque converter fit
I [nstallation procedure for the transmission is reverse
r the removing procedure, referring to "REMOVAL
rF TRANSMISSION" in 7 A-F.. In tightening the
rque converter and the drive plate, temporarily
drten four bolts frst,
then lock the drive plate
'u applying the wrench to the drive pulley lock bolt.
und tighten the four bolts to a specified torque of
3 7 - 5.5 m-kg |.27 - 40 ft-lb). In case of confirm-
's the tightening torque accurately, it is recommend-
. rie to proceed as follows:
rtall a torqrrc wrench to the hole in the center of
-= special wrench (49 0877 435), and tighten the
""it until the reading on the torque wrench
comes
the value to be obtained by the undermentioned
rmula.

4. Wtren the installation is finished, rotate the torque
converter and check to see that there is no interference
in the transmission. Then make the following check:
(1) Fill converter oil. The converter, when empty,
can hold 6.2 liters (13.1 U.S. pints, 10.9 lmp.
pints, 6.6 U.S. quarts). (7A-B-1)
(2) Check and regulate the manual linkage. (7 A-B.4)
(3) Check and regulate the inhibitor switch. (7A-B-5)
(4) Check and regulate the engine idling. (7A-B-2)
Apply the hand brake. With the engine idling,
place the manual lever in "N", "D", "2", ('1"
and "R", and check to see that there is a slight
strock of the transmission.
(5) Confirm the operation of the kickdown switch
and downshaft solenoid. (7A-B-3)
(6) Check the oil level again.
5. When checking and regulating arc over, conduct
stall test, road test and hydraulic test referring to
diagnostic test items (7A-C) in order to make sure
that the transmission works normally.
