not to damage the gasket with the bottom part of the
head.
51. INSPECT CYLINDER HEAD SET BOLT
(a) Using a vernier calipers, measure the length of cylinder
head bolt from the seat to the end.
Standard length: 146.8 to 148.2 mm (5.780 to 5.835 in.)
Maximum length: 148.5 mm (5.846 in.)

(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.
13. INSTALL CAMSHAFT TIMING GEAR OR SPROCKET (LEADED GASOLINE)
Torque: 54 Nm (551 kgfcm, 40 ftlbf)
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 Nm (551 kgfcm, 40 ftlbf)

tard angle side (to the right direction), and is locked at the
most retarded position.
