2.Turn the ignition switch
to the "LOCK" (OFF) position.
|
|
3.Remove all ignition
coils.
|
|
4.Remove the rocker
cover.
|
|
5.Turn the crankshaft
clockwise until the notch on the pulley is lined up with the
"T" mark on the timing indicator.
|
|
6.Move the rocker arms on
the No.1 and No.4 cylinders up and down by hand to determine
which cylinder has its piston at the top dead centre on the
compression stroke. If both intake and exhaust valve rocker
arms have a valve lash, the piston in the cylinder
corresponding to these rocker arms is at the top dead centre
on the compression stroke.

7.Valve clearance inspection
and adjustment can be performed on rocker arms indicated by
white arrow mark when the No.1 cylinder piston is at the top
dead centre on the compression stroke, and on rocker arms
indicated by black arrow mark when the No.4 cylinder piston
is at the top dead centre on the compression
stroke. 8.Measure the valve clearance. If the
valve clearance is not as specified, loosen the rocker arm
lock nut and adjust the clearance using a thickness gauge
while turning the adjusting screw. Standard
value (hot engine):
Intake valve: 0.20
mm Exhaust valve: 0.30
mm
9.While holding the adjusting
screw with a screwdriver to prevent it from turning, tighten
the lock nut to the specified
torque. Tightening torque: 9 ± 1
N·m 10.Turn the crankshaft through
360 degree angle to line up the notch on the crankshaft
pulley with the "T" mark on the timing
indicator. 11.Repeat steps (9) and (10) on other
valves for clearance adjustment. 12.Install the
rocker cover. 13.Install the ignition
coils.
