Variable Valve Timing Actuator Removal/Installation

WARNING: This page is about a different car, the 2004 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • The variable valve timing actuator cannot be disassembled because it is a precision unit.
NOTE:
  • Intake camshaft sprocket is integrated with the variable value timing actuator and cannot be disassembled.
  1. Follow the valve clearance adjustment procedure from 1 to 20 and remove the intake camshaft and variable value timing actuator as a single unit.

    (See VALVE CLEARANCE ADJUSTMENT .)

  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.
    2. Secure the camshaft in a vise.
    3. Loosen the variable valve timing actuator tightening bolt.

      • When the variable valve timing actuator is replace with a new one, mark it in the same location as the old one.
    3. Tighten the variable valve timing actuator tightening bolt.

    Tightening torque 69-75 N.m {7.1-7.6 kgf.m, 50.9-55.3 ft.lbf} 

  4. Follow the valve clearance adjustment procedure from 24 to 48 and install the intake camshaft and variable valve timing actuator. (See VALVE CLEARANCE ADJUSTMENT .)
