3. Attach the primary timing chain.
Attach the primary chain over the variable camshaft timing oil control unit (or intake camshaft sprocket - vehicles fitted with supercharger). There
must be no slack on the drive side of the primary chain and the variable camshaft timing oil control unit must not be rotated on the camshaft (or the
tensioning tool may not fit).
4. Reposition the timing chain assembly along the intake camshaft.
5. Install the primary chain tensioner blade.
Position the tensioner blade to the cylinder block.
Install the retaining / pivot bolt and tighten it to 12-16 Nm.
6. Push the tensioner piston into the body to provide clearance for fitting.
Install a thin rigid wire through the hole in the end of the tensioner piston to displace the ball from the non-return valve seat.
With the wire in position, press the piston fully into the tensioner body.
Remove the wire.
