      *1 Camshaft Timing Gear
      *2 Flange
      *a INCORRECT
      *b CORRECT
      *c Clearance
      *d No Clearance

      Check that there is no clearance between the camshaft timing gear and camshaft flange.

    3. Secure the camshaft in place by hand, and then install the installation bolt of the camshaft timing gear by hand.

      Note

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

    4. Check the lock of the camshaft timing gear.


      1. Make sure that the camshaft timing gear is locked.

        Note

        Be careful not to damage the camshaft.

    5. A01I60SE05

      Release the lock pin.

      *1 Rubber
      *2 Vinyl Tape
      *3 Knock Pin
      *a Retard Side Path
      *b Advance Side Path
      *c Open
      *d Close

      1. Clean the camshaft journal with non-residue solvent.

      2. Cover the 4 oil paths of the cam journal with vinyl tape as shown in the illustration.

        Tech Tips

        There are 4 oil paths in the grooves of the camshaft. Plug three of the paths with pieces of rubber.

      3. Open a hole at port A shown in the illustration.

      4. A01I4Y6

        While applying approximately 200 kPa (2.0 kgf/ cm2, 29 psi) of air pressure to the oil path, forcibly turn the camshaft timing gear assembly in the advance direction (counterclockwise).

        CAUTION:

        Cover the paths with a piece of cloth when applying pressure to keep oil from spraying.

        Note

        Do not allow the camshaft timing gear assembly to lock. If it locks, 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.

    6. Check for smooth rotation.


      1. Turn the camshaft timing gear within its movable range (26.5 to 28.5°) 2 or 3 times, but do not turn it to the most retarded position. Make sure that the gear turns smoothly.

        Note

        Do not allow the camshaft timing gear assembly to lock.

        If it locks, release the lock pin again.

    7. Remove the vinyl tape and rubber pieces from the camshaft.
