turned OFF
(2) Remove the cylinder head cover No.2.
(3) Pull out the wire harness as shown in the illustration.
Connect the clip of the timing light to the engine.
NOTICE:

Use a timing light which detects the first signal.

After checking, be sure to wrap the wire harness with
tape.
(4) Inspect ignition timing at idle.
Ignition timing: 8 to 12  BTDC
NOTICE:
When checking the ignition timing, shift the transmission
to the neutral position.

(c) Put air pressure into the oil port with 150 kpa (1.5 kgf/cm2
21 psi), and turn the camshaft timing gear to the advance
direction (counterclockwise) by hand.
CAUTION:
Cover the paths with shop rag to avoid oil splashing.
HINT:
Depending on the air pressure, the camshaft timing gear will
turn to the advance angle side without applying force by hand.
Also, under the condition that the pressure can be hardly ap-
plied because of the air leakage from the port, there may be the
case that the lock pin could be hardly released.
(d) Remove the fringe bolt of camshaft timing gear.
NOTICE:

Be sure not to remove the other 4 bolts.

If reusing the camshaft timing gear, release the
straight pin lock first, and then install the gear.

14. INSTALL CAMSHAFT TIMING GEAR ASSY
(UNLEADED GASOLINE)
(a) Put the camshaft timing gear and the camshaft together
with the straight pin off the key groove.
(b) Turn the camshaft timing gear assembly to the left direc-
tion (as shown in the illustration) while lightly pushing it to-
ward the camshaft. Push further at the position where the
pin gets into the groove.
NOTICE:
Be sure not to turn the camshaft timing gear to the retard
angle side (to the right direction).
(c) Check that there is no clearance between the gear's
fringe and the camshaft.
(d) Tighten the fringe bolt with the camshaft timing gear fixed.
Torque: 54 N
