        *a Adhesive Tape Sealing Area
        *b Make a Hole
        NOTE:

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

      2. Make a hole in the adhesive tape covering the oil hole as shown in the illustration. (Procedure A)
      3. Apply approximately 200 kPa (2.0 kgf/ cm2 , 29 psi) of air pressure to the hole made in procedure A to release the lock pin.
        GTY290869Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
        NOTE:
        • If air leaks out, reattach the adhesive tape.
        • Cover the oil hole with a piece of cloth when applying air pressure to prevent oil from spraying.
      4. Forcibly turn the camshaft timing gear in the advance direction (counterclockwise).

        HINT: 

        Depending on the air pressure applied, the camshaft timing gear may turn in the advance direction without assistance by hand.

      5. Remove the adhesive tape from the camshaft bearing cap.
    9. Using a wrench to hold the hexagonal portion of the camshaft, install the bolt.
