side to the hole of the advance side path, as
shown in the illustration.
(3) Apply approximately 200 kPa (2.0 kgf/cm
2
, 28
psi) of air pressure to the 2 broken paths.
CAUTION:
Cover the paths with a piece of cloth when
applying pressure to keep oil from
splashing.
(4) Check that the camshaft timing gear revolves in
the advance direction when reducing the air
pressure applied to the retard side path.
HINT:
This operation releases the lock pin for the
most retarded position.
(5) When the camshaft timing gear reaches the
most advanced position, release the air
pressure from the retard side path and advance
side path, in that order.

Do not release the air pressure from the
advance side path first. The gear may
abruptly shift in the retard direction and
break the lock pin.
