– CAMSHAFT (1ZZ–FE/3ZZ–FE)
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, next, take out 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 straight pin lock 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 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.
