  29. REMOVE CAMSHAFT TIMING GEAR ASSEMBLY


    1. Check the lock of the camshaft timing gear assembly.

    2. Release the lock pin.

      Note

      Before removing the camshaft timing gear assembly, make sure that the lock pin has been released.


      1. A01D6A4C13
        *a Adhesive Tape Sealing Area
        *b Prick a Hole
        *c Adhesive Tape

        Clean the VVT oil hole on the intake side of the camshaft bearing cap, and completely seal the oil hole with adhesive tape or equivalent as shown in the illustration to prevent air from leaking.

        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. Prick a hole in the adhesive tape sealing the oil hole as shown in the illustration. (Procedure A)

      3. A01D5A1

        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.

        Note


        • 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 assembly. If it is locked, release the lock pin again.

        Tech Tips


        • The camshaft timing gear assembly 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 camshaft bearing cap.

    3. A01D547C12
      *a Do not Remove

      Remove the bolt while holding the hexagonal portion of the camshaft, then remove the camshaft timing gear assembly.

      • Before removing the camshaft timing gear assembly, make sure that the lock pin has been released.

      • Be sure not to remove the other 4 bolts.

      • Keep the camshaft timing gear assembly horizontal while removing it from the camshaft.

  30. REMOVE CAMSHAFT TIMING EXHAUST GEAR ASSEMBLY


    1. A01D6A7C12
      *a Do Not Remove
