  6. Install new VVEL actuator sub assembly as per the following:
    CAUTION: Regarding replacement, because VVEL actuator sub assembly and VVEL control shaft position sensor are controlled on a one-on-one basis, replace them as a set.
    NOTE:
    • VVEL actuator arm (B) is factory-fixed at 10 degrees from the small lift with a holding jig (A).
    • The holding jig is supplied in the new VVEL actuator sub assembly.

      CAUTION: Be careful not to damage the stopper surface.
      • If control shaft cannot be moved, set crankshaft in position referring to the information below. (To displace cam nose)

        Bank 1: Turn 360 degrees from No. 1 cylinder at TDC 

        Bank 2: No. 1 cylinder at TDC 

    2. Hold two flat areas of control shaft with a wrench, and rotate the control shaft (10 degrees from the stopper) to the large lift side. (This is for aligning the bolt hole of control shaft and the hole of VVEL actuator arm.)

      CAUTION:
      • When installing, be careful with VVEL actuator sub assembly (bank 1) mounting bolt No. 4 because its length is different.
      • Be sure to check that the VVEL actuator sub assembly is in contact with the cylinder head before tightening the mounting bolts.
    5. Remove holding jig.
    6. Check that VVEL actuator arm bolt hole is aligned with control shaft tapped hole. If it is not aligned, turn control shaft for alignment.
      CAUTION: Never give an impact to the magnet part. (A)

    7. Fix two flat areas (C) of control shaft with a wrench to tighten mounting bolts of control shaft.
      CAUTION:
      • During the operation, never allow a wrench to interfere with other parts.
      • Fix control shaft to prevent the interference of the stopper surface.
