Lift the primary chain and position it over the VVT unit sprocket (the VVT unit must be pulled forward to clear the cylinder head casting). There

Slide the VVT unit fully on to the camshaft.

Install the retaining/pivot bolt and tighten it to 12 - 16 Nm.

Use a wedge 303-533 (or two if required) between the primary chain tensioner and tensioner blade, to take up the slack in the chain.
