unit to the inlet and the sprocket to the exhaust.
2. Fit, but do not tighten, each bolt which secures the VVT unit and the exhaust sprocket to the camshafts.

7. Tighten the exhaust camshaft sprocket securing bolt.
1. Fit the chain tensioner tool 303 - 532 to the sprocket holes.
Apply force to the tool in an anti-clockwise direction to
tension the chain on its drive side.
2. Whilst applying the opposing force to the sprocket and chain, tighten the sprock et securing bolt to 115 -
125 Nm.

8. Tighten the VVT unit securing bolt.
1. Whilst still applying the opposing force to the
sprocket and chain (using 303 - 532), check that the
wedges are still in place, tighten the VVT unit
securing bolt to 115 - 125 Nm.
Remove the chain tensioning tool and the wedge(s).
9. Remove the camshaft locking tool 303 - 530.
10. Raise the vehicle on the ramp.
11. Remove the crankshaft setting tool 303 - 531.

12. Refit the crankshaft position sensor.
1. Fit the sensor to the fl ywheel housing and fit the
securing bolt. Tighten to 8-12 Nm.
2. Refit the access grommet to the housing.
13. Lower the ramp.
14. Refit the A-Bank VVT Bush Carrier Assembly. Refer to
operation 12.65.51 in this Section.
15. Refit the Timing Cover. Refer to Operation 12.65.01 in this
Section.
