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.

CAMSHAFT
Put air pressure into two broken paths (the advance side
path and the retard side path) with about 150 kPa {1.5
kgf⋅cm}.
Confirm if the camshaft timing gear assembly revolves in
the timing advance direction when weakening the air
pressure of the timing retard path.
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.
Remove the fringe bolt of camshaft timing gear assembly.
Be sure not to remove the other 4 bolts.
In case of reusing the camshaft timing gear, release
the strait pin locking first, and then install the gear.
INSTALL CAMSHAFT TIMING GEAR ASSY
Put the camshaft timing gear assembly and the camshaft
together with the straight pin off the key groove.
Turn the camshaft timing gear assembly to the left direc-
tion (as shown in the illustration) with pushing it lightly
against the camshaft. Push further at the position where
the pin gets into the groove.
Check that there is no clearance between the gear's
fringe and the camshaft.
Tighten the fringe bolt with the camshaft timing gear fixed.
Torque: 54 N⋅m (551 kgf⋅cm 40 ft⋅lbf)
