    Torque Value: 31.4 N.m (3.2 kg-m, 23 ft-lb)
Install new VVEL actuator sub assembly as follows:
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 5.5 degrees from the small lift with a holding jig (A).
- The holding jig is supplied in the new VVEL actuator sub assembly.

CAUTION:
- Never disassemble VVEL actuator sub assembly. [Never loosen actuator motor mounting bolts (A) shown in the figure below]
- Never shock 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 120 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 (5.5 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 2) mounting bolt No. 1 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.
7. Fix two flat areas (C) of control shaft with a wrench to install 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.
Install new VVEL control shaft position sensor as follows:
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.
1. Apply engine oil to O-ring or contact surface of O-ring.
2. Align matching marks (B) of VVEL control shaft position sensor and upper housing.

  - Face connector toward matching mark (A).
3. Temporarily tighten bolt.
4. Adjust VVEL control shaft position sensor after setting the engine assembly in the vehicle. Refer to "VVEL CONTROL SHAFT POSITION SENSOR ADJUSTMENT: DESCRIPTION ".
  CAUTION: Be sure to adjust VVEL control shaft position sensor.
5. After adjusting VVEL control shaft position sensor, tighten bolts to the specified torque.
Inspect the valve clearance. Refer to "INSPECTION AND ADJUSTMENT ".
Install in the reverse order of removal after this step.
