Engine Oil Pressure
6. Engine Oil Pressure
A: INSPECTION
1) Disconnect the ground cable from battery.
2) Remove the generator from bracket.
3) Disconnect the connector from oil pressure
switch.
4) Remove the oil pressure switch from cylinder
block.
5) Connect the oil pressure gauge hose to cylinder
block.
6) Connect the battery ground cable to battery.
7) Start the engine, and then measure the oil pres-
sure.
Oil pressure:
Standard:
88 kPa (0.9 kg/cm
2, 13 psi) or more at 800 rpm
294 kPa (3.0 kg/cm2, 43 psi) or more at 5,000
rpmCAUTION:
If the oil pressure is out of specification,
check the oil pump, oil filter and lubrication
line.
If the oil pressure warning light is turned ON
and oil pressure is in specification, replace the
oil pressure switch.
in General.>
NOTE:
The specified data is based on an engine oil tem-
perature of 80°C (176°F).
8) After measuring the oil pressure, install the oil
pressure switch.
Tightening torque:
25 N
⋅m (2.5 kgf-m, 18.1 ft-lb)
9) Install the generator and V-belt in the reverse or-
der of removal, and then adjust the V-belt deflec-
tion.

Valve Clearance
8. Valve Clearance
A: INSPECTION
NOTE:
Inspection and adjustment of the valve clearance
should be performed while engine is cold.
1) Set the vehicle on a lift.
2) Lift-up the vehicle.
3) Remove the under cover.
4) Lower the vehicle.
5) Disconnect the ground cable from battery.
6) Remove the belt cover (LH).
7) When inspecting the #1 and #3 cylinders:
(1) Disconnect the spark plug cords from spark
plugs RH side.
(2) Disconnect the PCV hose from rocker cover
(RH).
(3) Remove the bolts, and then remove the
rocker cover (RH).
8) When inspecting the #2 and #4 cylinders:
(1) Disconnect the spark plug cords from spark
plugs (LH Side)
(2) Disconnect the PCV hose from rocker cover
(LH).
(3) Remove the bolts, and then remove the
rocker cover (LH).
9) Set the #1 cylinder piston to top dead center of
compression stroke by rotating crank pulley clock-
wise using a socket wrench.NOTE:
When arrow mark (A) on the cam sprocket (LH)
comes exactly to the top, #1 cylinder piston is
brought to the top dead center of compression
stroke.
10) Measure the #1 cylinder valve clearance by us-
ing thickness gauge.
CAUTION:
Insert the thickness gauge (A) in as horizon-
tal a direction as possible with respect to the
valve stem end face.
Measure the exhaust valve clearances while
lifting-up the vehicle.
Valve clearance (Standard):
Intake;
0.20
±0.04 mm (0.0079±0.0016 in)
Exhaust;
0.25
±0.04 mm (0.0098±0.0016 in)
11) If necessary, adjust the valve clearance.
ance.>
12) Similar to measurement procedures used for
#1 cylinder, measure the #2, #3 and #4 cylinder
valve clearances.
NOTE:
Be sure to set the cylinder pistons to their re-
spective top dead centers on compression stroke
before measuring valve clearances.

Valve Clearance
To set the #3, #2 and #4 cylinder pistons to their
top dead centers on compression stroke, turn the
crank pulley clockwise 90° at a time starting with ar-
row mark on cam sprocket (LH) facing up.
13) After inspection, install the related parts in the
reverse order of removal.
Tightening torque:
Resonator chamber;
33 N
⋅m (3.4 kgf-m, 25 ft-lb)
B: ADJUSTMENT
NOTE:
Adjustment of the valve clearance should be per-
formed while engine is cold.
1) Set the #1 cylinder piston to top dead center of
compression stroke by rotating crank pulley clock-
wise using socket wrench.
NOTE:
When arrow mark (A) on the cam sprocket (LH)
comes exactly to the top, #1 cylinder piston is
brought to the top dead center of compression
stroke.2) Adjust the #1 cylinder valve clearance.
(1) Loosen the valve rocker nut and screw.
(2) Place suitable thickness gauge.
(3) While noting the valve clearance, tighten the
valve rocker adjusting screw.
(4) When specified valve clearance is obtained,
tighten the valve rocker nut.
Tightening torque:
10 N
⋅m (1.0 kgf-m, 7.2 ft-lb)
CAUTION:
Insert the thickness gauge in as horizontally
as possible with respect to the valve stem end
face.
Adjust the exhaust valve clearances while
lifting up the vehicle.
Valve clearance:
Intake:
0.20
±0.04 mm (0.0079±0.0016 in)
Exhaust:
0.25
±0.04 mm (0.0098±0.0016 in)
3) Ensure the valve clearances are within specifi-
cations.
4) Turn the crankshaft two complete rotations until
#1 cylinder piston is again set to the top dead cen-
ter of compression stroke.
5) Ensure the valve clearances are within specifi-
cations. If necessary, readjust the valve clearanc-
es.
6) Similar to adjustment procedures used for #1
cylinder, adjust the #2, #3 and #4 cylinder valve
clearances.
