(c) Put air pressure into two broken paths (the advance side path and the retard side path) with about 150 kPa {1.5
kgf
cm}.
CAUTION:
Cover the paths with shop rag to avoid oil splashing.
(d) Confirm if the camshaft timing gear assembly revolves in the timing advance direction when weakening the air
pressure of the timing retard path.
HINT:
When the lock pin is released, the camshaft timing gear re-
volves in the advance direction.
(e) When the camshaft timing gear comes to the most ad- vanced position, take out the air pressure of the timing re-
tard side path, next, take out that of timing advance side
path.
CAUTION:
Camshaft timing gear assembly occasionally shifts to the
retard side abruptly, if the air compression of the advanced
side path is released first. It often causes the breakage of
the lock pin.
(f) Remove the fringe bolt of camshaft timing gear assembly.
NOTICE:

Be sure not to remove the other 4 bolts.

In case of reusing the camshaft timing gear, release
the straight pin lock first, and then install the gear.
17. INSTALL CAMSHAFT TIMING GEAR ASSY
(a) Put the camshaft timing gear assembly and the camshaft together with the straight pin off the key groove.
(b) Turn the camshaft timing gear assembly clockwise (as shown in the illustration) while pushing it lightly against
the camshaft. Push further at the position where the pin
gets into the groove.
CAUTION:
Be sure not to turn the camshaft timing gear to the retard
angle side (to the right angle).

HINT:
If the plunger does not be extended, press the slipper into the
chain tensioner using a screwdriver so that the hook is took off
from the knock pin and let the plunger can be extended.
