  Caution
  • Variable valve timing actuator can not be disassembled because it is a precision unit.

  Note
  • Intake camshaft sprocket is integrated with the variable valve timing actuator and cannot be disassembled.

1. Follow the valve clearance adjustment procedure from 1 to 23 and remove the intake camshaft and variable valve timing actuator as a single unit. (See VALVE CLEARANCE ADJUSTMENT [L8, LF].)

2. Remove the variable valve timing actuator.

  (1) Mark the camshaft and variable valve timing actuator as shown in the figure to make sure they are installed in their original position.

    69—75 N·m {7.1—7.6 kgf·m, 50.9—55.3 ft·lbf}

5. Follow the valve clearance adjustment procedure from 24 to 54 and install the intake camshaft and variable valve timing actuator. (See VALVE CLEARANCE ADJUSTMENT [L8, LF].)

  Note
  • If the alignment marks on the variable valve timing actuator are not available, refer to the “TIMING CHAIN ASSEMBLY“ in the engine workshop manual and perform the sprocket position alignment again.
