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 an
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 1/2²-16
ACME.
CALIBRATING ACR4 WEIGHT SCALE
Calibrate the scale every three months.
To calibrate the weight scale on the ACR4 :
1. PressShift/ResetandEnterat the same time.
2. Press8787.“A1” will be displayed.
3. Remove all weight from the scale.
4. Press0,thenpressEnter.“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. PressEnter— the display returns to the vacuum mode.
8. PressShift/ResetandEnterat the same time.
9. Press6— 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 sShift/Resetto return the ACR4 to the program mode.

INSPECTION
lWhen the camshaft or parts in connection with valves are
removed or replaced, and a malfunction has occurred (poor
starting, idling, or other malfunction) due to the mis adjustment
of the valve clearance, inspect as follows.
lInspect and adjust when the engine is cool (at normal tempera-
ture).
lBe careful of the intake and exhaust valve arrangement. The
valve arrangement is different from that in a normal engine.
NOTE:
The camshafts have, alternately, either an intake valve or an
exhaust valve.(Refer to illustration)
1. Drain engine coolant. Refer toCO-30, "
Changing Engine Coolant".
2. Remove charge air cooler. Refer toEM-114, "
Removal and Installation".
3. Remove air duct and air inlet pipe. Refer toEM-112, "
Removal and Installation".
4. Remove rocker cover. Refer toEM-147, "
Removal and Installation".
5. Remove vacuum pump. Refer toEM-131, "
Removal and Installation".
6. Remove injection tube and fuel injector. Refer toEM-135, "
Removal and Installation".
7. Remove secondary timing chain. Refer toEM-158, "
Removal and Installation"
Check valve clearance while engine is cold and not running.
8. Set the No. 1 piston to TDC on its compression stroke.
lTurn crankshaft pulley clockwise so that the knock pin on
camshaft LH faces straight above. (No position indicator, etc.
is provided on the crankshaft pulley.)
9. Put an alignment mark with paint, etc. on the crankshaft pulley
and on the oil pump as an angle indicator.
10. While referring to the figure, measure the valve clearance
marked in the table below.
lThe injection order is 1-3-4-2.

lMeasure the valve clearance using a fine feeler gauge when
the engine is cool (at normal temperature).
11. Set the No. 4 cylinder at TDC by rotating the crankshaft clock-
wise once.
12. While referring to the figure, measure the valve clearance
marked in the table below.
13. If the valve clearance is outside the specification, adjust as fol-
lows.
ADJUSTMENTS
lRemove the adjusting shim for parts which are outside the spec-
ified valve clearance.
1. Remove the spill tube. Refer toEM-135, "
Removal and Installa-
tion".
2. Extract the engine oil on the upper side of the cylinder head (for
theairblowinginstep7).
3. Rotate the crankshaft to face the camshaft for adjusting shims
that are to be removed upward.
4. Grip the camshaft with camshaft pliers, them using the camshaft
as a support point, push the adjusting shim downward to com-
press the valve spring.
CAUTION:
Do not damage the camshaft, cylinder head and the outer
circumference of the valve lifter.Valve clearance (Cold):
Standard:
Intake : 0.24 - 0.32 mm (0.0094 - 0.0126 in)
