28. REMOVE CAMSHAFT TIMING GEAR OR SPROCKET
(a) Fix the camshaft with a vise and remove the camshaft tim-
ing sprocket.
NOTICE:
Be careful not to damage the camshaft.
29. REMOVE CAMSHAFT TIMING GEAR ASSY
(a) Fix the camshaft with a vise, and make sure that the cam-
shaft timing gear does not move.
(b) Cover all the oil ports with vinyl tape except the advanced
angle side, as shown in the illustration.
(c) Using an air gun, apply about 150 kPa (1.5 kgf/cm
2, 21
psi) of air pressure to the port on the advanced angle side.
CAUTION:
Some oil spraying will occur. Contain the spray with a shop
rag.
HINT:
This operation releases the lock pin for the extreme retarded
angle lock.
(d) Under the condition above, check that the camshaft tim-
ing gear can be turned by hand to the advanced angle
side (counterclockwise), the direction of the arrow shown
in the illustration.
Standard: Must turn
HINT:
The camshaft timing gear will turn to the advanced angle side
without applying force by hand depending on the force of the
air pressure applied. Also, if applying pressure to the oil path is
difficult as a result of air leakage from the port, the lock-pin may
be difficult to release.
(e) Remove the fringe bolt from the camshaft timing gear.
NOTICE:

Be sure not to remove the other 4 bolts.

If planning to reuse the camshaft timing gear, release
the straight pin lock first, and then install the gear.
