NOTICE:
Be sure to cover the oil hole completely because air leaks due to insufficient sealing will prevent the lock pin from being released.

(2) Prick a hole in the tape covering the oil hole as shown in the illustration (Procedure A).

(3) Apply approximately 150 kPa (1.5 kgf/cm2, 22 psi) of air pressure to the hole pricked in procedure A to release the lock pin.





NOTICE:
* If air leaks out, reattach adhesive tape.
* Cover the oil hole with a piece of cloth when applying air pressure to prevent oil from spraying.
* Do not lock the camshaft timing gear. If it is locked, release the lock pin again.

HINT
* The camshaft timing gear may be turned in the advance direction without applying any force.
* If enough air pressure cannot be applied because of air leakage from the port, releasing the lock pin may be difficult.

(4) Remove the adhesive tape from the No. 1 camshaft bearing cap.

(c) Remove the flange bolt while holding the hexagonal portion of the camshaft, and then remove the camshaft timing gear.
