CAMSHAFT TIMING GEAR ASSEMBLY

Align the alignment pin with the groove and install the VVT-i on the camshaft.

NOTE: Install it with the lock-pin engaged and locked at the most retard angle position.

Apply engine oil to the nut, the mounting surface of VVT-i and the screw threads.

NOTICE:
- Be sure to apply oil, otherwise the specified torque cannot be obtained.
- A new nut must be used when replacing the VVT-i unit.

Using a 46 mm socket wrench, install and tighten a lock nut by turning it counterclockwise.
