2) Connect the oil pressure gauge hose to cylinder
block.
3) Connect the ground cable to the battery.
4) Start the engine, and measure the oil pressure.
OIL PRESSURE (at oil temperature of 80°C
(176°F)):
Standard:
135 kPa (1.4 kgf/cm2, 20 psi) or more (at
600 rpm)
500 kPa (5.1 kgf/cm2, 73 psi) or more (at
5,000 rpm)
CAUTION:
•If the oil pressure is out of specification,
check oil pump, oil filter and lubrication line.
Diagnostics Table.>
•If the oil pressure warning light is turned ON
and oil pressure is in specification, replace the
oil pressure switch.
SPECTION, General Diagnostics Table.>
5) After measuring the oil pressure, install the oil
pressure switch.

Valve Clearance
MECHANICAL
10) Measure the clearance of intake valve and ex-
haust valve using thickness gauge (A).
NOTE:
•Measure it within the range of ±30° from speci-
fied position shown in the figure.
•Measure it in low lift cam for intake side.
•Insert a thickness gauge in a direction as hori-
zontal as possible with respect to the valve lifter.
Valve clearance
Intake:
0.20 +0.04 –0.06 mm (0.0079 +0.0016 –0.0024 in)
Exhaust:
0.35±0.05 mm (0.0138±0.0020 in)
•If the measured value is not within specification,
take notes of the value in order to adjust the valve
clearance later on.
11) If necessary, adjust the valve clearance.

ance.>
12) Further turn the crank pulley clockwise and
then measure the valve clearances again.
13) After inspection, install the related parts in the
reverse order of removal.
B: ADJUSTMENT
1. INTAKE SIDE
CAUTION:
•Adjustment of valve clearance should be per-
formed while engine is cold.
•Do not wear gloves during removal and in-
stallation of valve lifter.
•Do not use the valve lifter which got high im-
pact due to drop etc.
•When installing the valve lifter, align the anti-
rotation of valve lifter with groove on cylinder
head, and then insert the valve lifter.
1) Measure all the valve clearances.

NOTE:
Record each valve clearance after measurement.
2) Remove the camshaft.

3) Remove the valve lifter.
4) Remove the shim from valve lifter.
5) Check the thickness of the shim from the mark-
ings on the side of the shim that was removed.
6) Select a shim of suitable thickness from the fol-
lowing table using the measured valve clearance
and shim thickness.

B: INSTALLATION
NOTE:
•Be careful that the foreign matter is not into or
onto assembled component during installation.
•Apply engine oil to the chain guide, chain ten-
sioner lever and idler sprocket when installing.
1) Preparation for chain tensioner installation
(1) Insert the screw, spring pin and tension rod
into tensioner body.
(2) While depressing the tensioner onto rubber
mat, twist it to shorten tension rod. Then insert
the thin pin into the hole between tension rod
and tension body to keep it.
NOTE:
Work on the rubber mat or other anti-skid materials.
2) Using the ST, align the “Top mark” on crank
sprocket to 9 o’clock position as shown in the figure
