(a) Turn the cutout of the camshaft timing gear assembly eccentric shaft counterclockwise by hand, and set it to the maximum retard angle position.

HINT:

  • If a camshaft lobe is opening a valve, the eccentric shaft will be difficult to turn.
  • When the cutout of the camshaft timing gear assembly eccentric shaft cannot be turned any farther, it is set to the maximum retard angle.

Cutout

(b) Install the cam timing control motor with EDU assembly to the No. 2 timing chain cover assembly.

NOTICE:

  • When installing, align the joints of the cam timing control motor with EDU assembly with the cutouts of the camshaft timing gear assembly eccentric shaft.
  • Align the pin holes of the cam timing control motor with EDU assembly with the knock pins of the No. 2 timing chain cover assembly when installing the cam timing control motor with EDU assembly.
  • Make sure the contact surface of the cam timing control motor with EDU assembly (the surface that contacts the No. 2 timing chain cover assembly) is free of foreign matter.
  • When installing the cam timing control motor with EDU assembly, do not use excessive force.
  • If the cam timing control motor with EDU assembly has been struck or dropped, replace it.
  • Do not disassemble the cam timing control motor with EDU assembly. If disassembled, replace it.
