id0110a7801100

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, L5].)

2.  Remove the variable valve timing actuator.

Note

•  Do not add scratch marks to the camshaft thrust area.

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

(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.

(1)  Secure the camshaft in a vise.

(2)  Align the marks of the camshaft and variable valve timing actuator.

(3)  Tighten variable valve timing actuator tightening bolt.
