Electric Variable Valve Timing Motor/Driver Assembly Note

Install a new 0-ring to the 0-ring installation groove of the engine front cover.
CAUTION:
- To prevent damage to the electric variable valve timing motor/driver, do not apply excessive force (force of 100 N {10.2 kgf, 22.5 lbf} or more) to the shaded areas shown in the figure.
Install the electric variable valve timing motor/driver using the following procedures.
