9. F
it the chain tensioning tool 303 - 532 to the exhaust camshaft
sprocket, A-Bank.
Re
position the sprocket (and
the VVT unit) for the most
advantageous position for use of the tool.
R
emove the tool.

10
.
Refit the primary timing chain, A-Bank.
1. Fit the primary chain 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 rotate d on the camshaft.

11
.
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.
12. Refit the primary chain tens ioner assembly. Refer to
Operation 12.65.54 in this Section.
U
se a wedge 303 - 533 (or two if required) between the
primary chain tensioner and te nsioner blade, to take up
the slack in the chain.

2
. Fit a new O-ring to the carrier oil-way.

21
.
NOTE: Lubricate the seal (s carf jointed) and the bush.
Fit the VVT bush carrier to the cylinder block.
1. Fit the bush carrier assembly.
1. C
heck that the seals are in place and that the ring
dowels are engaged squa rely. Fully locate the
assembly as much as possible by hand pressure.
2
. Fit the three securing bolts. Tighten to 19 - 23 Nm.

22
.
Fit new seals to the VVT bush carrier, B-Bank.
1. Fit the new sealing ring (scarf jointed) to the carrier bush groove.
2. Fit a new O-ring to the carrier oil-way.

23
.
NOTE: Lubricate the seal (s carf jointed) and the bush.
Fit the VVT bush carrier to the cylinder block. 1. Fit the bush carrier assembly.
1. C
heck that the seals are in place and that the ring
dowels are engaged squa rely. Fully locate the
assembly as much as possible by hand pressure.
2
. Fit the two securing bolts and one nut. Tighten to 19
- 23 Nm.
24. Refit the Timing Cover. Refer to Operation 12.65.01 in this
Section.
25. Move the engine compartment cover from the service position
and connect the gas struts.
26. Remove the paint protection sheets and close the cover.
27. Connect the battery and fit the battery cover.
