Here is how the job is done to replace the timing chain and to retime the engine camshaft.

You must re-time the LH and RH camshafts when either camshaft is disturbed.

Turn the crankshaft one revolution clockwise.

Install the special tool. The special tool must be installed on the damper and should contact the engine block, this positions the engine at top dead center (TDC). Using the special tool, loosen the RH camshaft sprocket bolt. The right-hand camshaft sprocket bolt is a left-hand threaded bolt. Position the camshaft timing slots below the centerline of the camshaft to correctly fit the special tools and install the special tools on the front of the RH cylinder head. The camshaft timing slots are off-center.
Install the special tools on the rear of the RH cylinder head. Leave the top two special tool clamp bolts loose. The right-hand camshaft sprocket bolt is a left-hand threaded bolt.

Check out the diagrams below

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken
