camshafts, aligning the shafts slightly as necessary.

15. Loosen the bolt which secures the sprocket to the camshaft.

16. Loosen the bolt which secure s VVT unit to the camshaft.
17. Remove the primary ch ain tensioner bolts.

Reposition the sprocket (and the VVT unit) for the most
advantageous position for use of the tool.
Remove the tool.

3. Refit the primary timing chain.
1. Fit the primary chain to position over the crankshaft sprocket and the VVT unit sprocket. There must be no
slack on the drive side of the primary chain and the
VVT unit must not be rotated on the camshaft.

4. Fit the primary chain tensioner blade.
1. Position the tensioner blade to the cylinder block.
2. Fit the retaining / pivot bolt and tighten it to 12-16 Nm.

5. Refit the primary chain tensione r assembly. Refer to Operation
12.65.54 in this Section.
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.
6. 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

Lubricate the seal (scarf jointed) and the bush.
1. Fit the bush carrier assembly.
Check that the seals are in pl ace and that the ring dowels
are engaged squarely. Fully locate the assembly as much
as possible by hand pressure.
2. Fit the three securing bolts. Tighten to 19-23 Nm.
15. Refit the Timing Cover. Refer to Operation 12.65.01 in this
Section.
16. Move the engine compartment cover from the service position
and connect the gas struts.
17. Remove the paint protection sheets and close the cover.
18. Connect the battery and fit the battery cover.
Refer to the Battery Reconnection Procedure in Section
414-01.

Bank. Refer to Operation 12.65.55 in this Section.

7. Fit a Tie-Strap through the link s of the primary chain, just
above the crankshaft sprocket, to retain the chain to the
sprocket.

8. Rotate the inlet camshaft (and the exhaust camshaft), using a
spanner on the flats, to provide sufficient slack in the chain to
remove the chain tensioner blade.
9. Remove the chain tensioner blade.
1. Remove the pivot bolt which secures the tensioner blade.
