-
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 12 and remove the intake camshaft and variable valve timing actuator as a single unit.
(See VALVE CLEARANCE ADJUSTMENT [LF, L3].)
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.
-

Note
-
• Do not add scratch marks to the camshaft thrust area.
- (2) Secure the camshaft in a vise.
- (3) Loosen the variable valve timing actuator tightening bolt.
3. Install a new washer. (Except LF-VE (ATX).)
-
Note
-
• The washers do not have to be installed on the LF-VE (ATX) (there is no problem with installing them).
• Be careful not to install a washer on only the IN or EX side.
-
― If the washers are not installed, do not install the washers to both the IN and EX sides.
― If the washers are to be installed, install them on both the IN and EX sides.
