Align the positions of tightening bolts for drive plate with those of
torque converter, and temporarily tighten bolts. Then, tighten
bolts with the specified torque.
CAUTION:

When turning crankshaft, turn it clockwise as viewed from
front of engine.

When tightening the tighten bolts for the torque converter
after fixing crankshaft pulley bolts, be sure to confirm the
tightening torque of crankshaft pulley mounting bolts.
Refer to EM-53, "
TIMING CHAIN" (QR engine), EM-173, "TIMING CHAIN" (VQ engine).

After converter is installed to drive plate, rotate crankshaft several turns and make sure that tran-
saxle rotates freely without binding.

Install POS sensor. Refer to EM-145, "Removal and Installation" .

After completing installation, check for A/T fluid leakage, A/T fluid level, and positions of A/T. Refer to AT-
14, "Checking A/T Fluid" , AT- 2 1 5 , "Adjustment of A/T Position" , AT- 2 1 5 , "Checking of A/T Position" . : 52 N·m (5.3 kg-m, 38 ft-lb)

f. Check that low one-way clutch rotates counter-clockwise around
front planetary carrier. Then try to turn it clockwise and check
that it is locked.

Replace low one-way clutch if necessary.
g. Remove needle bearing, low & reverse brake piston and retainer
from front planetary carrier.

Check front planetary carrier, low & reverse brake piston,
retainer and needle bearing, and replace if damaged or worn.
h. Check clearance between planetary gears and planetary carrier
with feeler gauge.

Replace front planetary carrier if the clearance exceeds allow-
able limit.
40. Remove rear planetary carrier and rear sun gear according to the following procedures.
a. Remove rear planetary carrier (with rear sun gear) from tran-
saxle case.

SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or automatic) near the end of the hoses
opposite the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC-134a (R-134a) and speci-
fied lubricants have been used with the scale. If the scale controls
refrigerant flow electronically, the hose fitting must be 1/2
″ -16
ACME.
CALIBRATING ACR4 WEIGHT SCALE
Calibrate the scale every three months.
To calibrate the weight scale on the ACR4:
1. Press Shift/Reset and Enter at the same time.
2. Press 8787 . “A1 ” will be displayed.
3. Remove all weight from the scale.
4. Press 0 , then press Enter . “0.00 ” will be displayed and change to “A2 ”.
5. Place a known weight (dumbbell or similar weight), between 4.5 and 8.6 kg (10 and 19 lb.) on the center
of the weight scale.
6. Enter the known weight using four digits. (Example 10 lb. = 10.00, 10.5 lb. = 10.50)
7. Press Enter — the display returns to the vacuum mode.
8. Press Shift/Reset and Enter at the same time.
9. Press 6 — the known weight on the scale is displayed.
10. Remove the known weight from the scale. “0.00 ” will be displayed.
11 . P r e s s Shift/Reset to return the ACR4 to the program mode.
