LASER BEAM AIMING ADJUSTMENT
8. After the CONSULT-II displays “ADJUST THE VERTICAL OF
LASER BEAM AIMING” turn the vertical adjusting screw until
“U/D CORRECT” value is set in the range of ±4.
CAUTION:
Turn the screw slowly. The value on the CONSULT-II is
slower than the actual movement of the ICC sensor. Wait 2
seconds between each adjustment. Also, during adjust-
ment work, do not block the ICC sensor lens with your hand
or body. In that case, there are times when aiming cannot
be conducted correctly.
NOTE:
Turning the screw clockwise raises the ICC sensor and counter-
clockwise lowers the ICC sensor.
9. When “U/D CORRECT” value indicates ±4, confirm that the value remains within ±4 for at least 2 seconds
while nothing is touching the ICC sensor.
When “COMPLETED THE VERTICAL AIMING OF LASER
BEAM” appears on screen, touch “END”.
CAUTION:
Be sure that the margin of “U/D CORRECT” is within ±4
when the ICC sensor unit is untouched.
10. Confirm that “ADJUSTING AUTOMATIC HORIZONTAL LASER
BEAM AIMING” is on screen and wait while the horizontal
adjustment is made automatically. (maximum: 10 seconds).

• When installing transmission to the engine, attach the bolts as shown.
NOTE:
*: No.2 bolt also secures air breather vent.
CAUTION:
• When replacing an engine or transmission you must make
sure the dowels are installed correctly during re-assembly.
• Improper alignment caused by missing dowels may cause
vibration, oil leaks or breakage of drivetrain components.
• Align the positions of bolts for drive plate with those of the torque
converter, and temporarily tighten the bolts. Then tighten the bolts
with the specified torque.
CAUTION:
• When turning crankshaft, turn it clockwise as viewed from the
front of the engine.
• After converter is installed to drive plate, rotate crankshaft
several turns and check to be sure that transmission rotates
freely without binding.
• Install crankshaft position sensor (POS).
• After completing installation check fluid leakage, fluid level and the
positions of A/T. Refer to AT-13, "
Checking Automatic Transmis-
sion Fluid (ATF)", AT-208, "Checking of A/T Position" and AT-208, "Adjustment of A/T Position".

Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. T he HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. If an improper
connection is attempted, dischar ging and contamination may occur.
REFRIGERANT WEIGHT SCALE
Verify that no refrigerant other than HFC134a (R-134a) and specified
oils have been used with the scale. If the scale controls refrigerant
flow electronically, the hose fitting must be 1/2”-16 ACME.
CHARGING CYLINDER
Using a charging cylinder is not recommended. Refrigerant may be vented into air from cylinder's top valve
when filling the cylinder with refrigerant. Also, the accura cy of the cylinder is generally less than that of an
electronic scale or of quality recycle/recharge equipment.
