(4) Confirm if the camshaft timing gear assembly re-
volves in the timing advance direction when weak-
ening 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.
(5) When the camshaft timing gear comes to the most
advanced position, take out the air pressure of the
timing retard side path, and then take out that of tim-
ing advance side path.
CAUTION:
Camshaft timing assembly gear 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.
(c) Check smooth revolution
(1) Revolve the camshaft timing gear assembly within
the movable range [20
(40
CA)] except for the
most retarded position several times, and check the
smooth revolution.
CAUTION:
Be sure to perform this check by hand, instead of air pres-
sure.
(d) Check the lock in the most retarded position.
(1) Confirm that the camshaft timing gear assembly is
locked at the most retarded position.
16. REMOVE CAMSHAFT TIMING GEAR ASSY
(a) Clamp the camshaft in a vice, and confirm that the gear
is locked.
CAUTION:
Be careful not to damage the camshaft.
(b) Cover 4 oil paths of cam journal with vinyl tape as shown
in the illustration.
HINT:
The one of the 2 glooves on the cam journal is for retards (up-
per) and the rest is for advances (lower). Each groove has the
2 oil paths. Plug one of the oil paths for each groove with rubber
pieces before wrapping the cam journal with the tape.
(1) Punctuate the tape for the advance oil path and for
the retard oil path in the opposite side from the ad-
vance as shown in the illustration.

(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).
