    CAUTION:
    • When rotating the coupling, do not apply the torque more than 3 N.m (27 in-lb) to prevent the damage.
    • Do not forcibly push the worm wheel to the minimum lift stopper and the maximum lift stopper.
    • Never loosen the minimum lift stopper.
  2. Slowly rotate the coupling clockwise. When lightly touching the worm wheel to the minimum lift stopper, stop the worm wheel at the position shown in the illustration.
    NOTE: When rotating the coupling clockwise, the worm wheel should move in the minimum lift direction. When rotating the coupling counterclockwise, the worm wheel should move in the maximum lift direction.

    NOTE: When manually rotating the coupling, insert a 12-point socket (24 mm[0.9 inch]) into the position on the coupling approximately 5 mm (0.20 inch) away from the rocker shaft holder. Connect the mini torque wrench and slowly rotate them.
  3. Align the overhaul and installation marks for the V.V.T. sprocket rocker arm and camshaft assembly with the mark of the rocker shaft holder.
  4. Rotate the camshaft clockwise by approximately 15 degree so that the intake valve cannot be lifted.

    CAUTION:
    • Use isopropyl alcohol to degrease. Then check that liquid gasket application surface and recesses are not contaminated with oil or grease.
    • Do not touch the part to be degreased as fingerprints may affect sealing performance.
  5. Completely remove the liquid gasket adhered to the rocker arm and camshaft assembly and the cylinder head, and then degrease by white gasoline.
    CAUTION: Install the V.V.T. sprocket, the rocker arm and camshaft assembly to the cylinder head within 3 minutes of applying the liquid gasket.
  6. Apply the bead of 3.1 ± 0.3 mm (0.12 ± 0.01 inch) liquid gasket to the position as shown in the illustration.
