  2. INSPECT CAMSHAFT TIMING GEAR ASSEMBLY

    1. A293581C01

      *1

      Adhesive Tape

      *a

      Prick a Hole

      *b

      Adhesive Tape Sealing Area

      Inspect the lock of the camshaft timing gear assembly.

    2. After cleaning and degreasing the VVT oil hole on the intake side of 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.

      Note:

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

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

    4. A173367

      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 the adhesive tape.

      • Cover the oil hole with a piece of cloth when applying air pressure to prevent oil from spraying.

    5. Forcibly turn the camshaft timing gear assembly in the advance direction (counterclockwise).

      Tip:

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

    6. A173438

      Turn the camshaft timing gear assembly within its movable range (26.5 to 28.5°) 2 or 3 times without turning it to the most retarded position. Make sure that the camshaft timing gear assembly turns smoothly.

    7. Remove the adhesive tape from the No. 1 camshaft bearing cap.

  3. INSPECT CAMSHAFT TIMING EXHAUST GEAR ASSEMBLY

    1. A293583C01

      *1

      Adhesive Tape

      *a

      Prick a Hole

      *b

      Adhesive Tape Sealing Area

      Check the lock of the camshaft timing exhaust gear assembly.

    2. After cleaning and degreasing the VVT oil hole on the exhaust side of 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.

      Note:

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

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

    4. A173364

      Apply approximately 200 kPa (2.0 kgf/cm2, 28 psi) of air pressure to the hole pricked in procedure A to release the lock pin.

      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.

    5. Using a screwdriver with its tip wrapped with tape, forcibly turn the camshaft timing exhaust gear assembly in the retard direction (clockwise).

      Note:

      • Be sure to keep the camshaft timing exhaust gear assembly in the retard direction using a screwdriver. If the gear is released, it will return to the most advanced position automatically due to the force from the spring.

      • Do not damage the camshaft timing exhaust gear assembly.

    6. A173365

      Using a screwdriver with its tip wrapped with tape, turn the camshaft timing exhaust gear assembly within its movable range (19 to 21°) 2 or 3 times without turning it to the most advanced position. Make sure that the camshaft timing exhaust gear assembly turns smoothly.

    7. Remove the adhesive tape from the No. 1 camshaft bearing cap.

  4. REMOVE CAMSHAFT TIMING GEAR ASSEMBLY

    1. A153890

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

      A162976C05

      *1

      Flange Bolt

      *a

      Do Not Remove
      Note:

      • 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 horizontal while removing it from the camshaft.

  5. REMOVE CAMSHAFT TIMING EXHAUST GEAR ASSEMBLY

    1. A153891

      Remove the flange bolt while holding the hexagonal portion of the No. 2 camshaft, and then remove the camshaft timing exhaust gear assembly.

      A162977C02

      *1

      Flange Bolt

      *a

      Do Not Remove
      Note:

      • Be sure not to remove the other 4 bolts.

      • Keep the camshaft timing exhaust gear horizontal while removing it from the No. 2 camshaft.

  6. REMOVE CAMSHAFT BEARING CAP

    1. A150879E01

      Uniformly loosen and remove the 10 bearing cap bolts in the sequence shown in the illustration.

    2. A152591E01

      Uniformly loosen and remove the 15 bearing cap bolts in the sequence shown in the illustration.

      Note:

      Uniformly loosen the bolts while keeping the camshaft level.

    3. Remove the 5 camshaft bearing caps.

      Tip:

      Arrange the removed parts in the correct order.
