19. REMOVE CAMSHAFT TIMING GEAR ASSY
(a) Grip the camshaft with 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:
Two advance side paths are provided in the groove of the cam-
shaft. Plug one of the path with a rubber piece.
(c) Break through the tapes of the advance side path and the
retard side path on the opposite side of the groove.
(d) Put air pressure into two broken paths (the advance side
path and the retard side path) with about 150 kPa {1.5 kgf/
cm
2}.
CAUTION:
Cover the pathes with shop rag to avoid oil splashing.
(e) Confirm if the camshaft timing gear assembly revolves in
the timing advance direction when weakening the air
pressure of the timing retard path.
HINT:
The lock pin is released, and camshaft timing gear revolves in
the advance direction.
(f) When the camshaft timing gear comes to the most ad-
vanced position, take out the air pressure of the timing re-
tard side path, and then, takeout 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 before retard side paths. It often
causes the breakage of the lock pin.
