    2. Using the SST, turn the intake cam sprocket LH approximately 180° clockwise and align the alignment mark of intake cam sprocket LH to the position (zero-lift position) as shown in the figure.

      SST 18355AA000, 18334AA020

      CAUTION:
      • Pay attention when performing the work, since the SST comes off easily.
      • After this work, when the intake valve and exhaust valve lift at the same time, the valve heads contact each other and valve stems may bend. Do not turn the intake camshaft LH and exhaust camshaft LH to the outside of range of zero-lift (in range where it can be turned lightly by hand).
    3. Remove the SST from the crankshaft.
  31. Intake cam sprocket RH removal
    1. Use the SST to secure the intake cam sprocket RH and remove the three bolts.

      SST 18355AA000, 18334AA020, 18270KA010

      CAUTION: Pay attention when performing the work, since the SST comes off easily.
    2. Remove the intake cam sprocket RH.
