      NOTE:

      Do not use any tools to install the bolt. If the bolt is installed using a tool, the lock pin will be damaged.

    8. If the lock pin has not been released, release it.
      1. After cleaning the intake side VVT oil hole on the No. 1 camshaft bearing cap, completely seal the oil hole with adhesive tape or equivalent as shown in the illustration to prevent air from leaking.
        GTY434369Courtesy of © TOYOTA, LICENSE AGREEMENT TMS1002
        *a Make a Hole
        *b Adhesive Tape Sealing Area
        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 assembly in the advance direction (counterclockwise).

        HINT: 

        • Depending on the air pressure applied, the camshaft timing gear assembly may turn in the advance direction without assistance by hand.
        • If enough air pressure cannot be applied because of air leakage from the port, releasing the lock pin may be difficult.
      5. Remove the adhesive tape from the No. 1 camshaft bearing cap.
    9. Using a wrench to hold the hexagonal portion of the camshaft, install the bolt.

      *b Turn

      Torque: 85 N*m (867 kgf*cm, 63 ft.*lbf) 

      NOTE:

      Be careful not to damage the cylinder head sub-assembly or spark plug tube with the wrench.
