emove the crankshaft position sensor.
1. Remove the bolt which secures the crankshaft position sensor to the flywheel housing.
Remove the
sensor and allow
it to hang free under the
engine.

the drive plate is visible thro ugh the access hole; confirm
that the timing flat on ea ch camshaft is uppermost.
11. Fit the crankshaft setting peg 303 - 531 to the crankshaft
position sensor location.

1.
Fit the crankshaft setting peg 303 - 531.
Position the crankshaft so
that the setting
peg engages
fully into the timing slot.

it the camshaft locking tool 303 - 530 to the A-Bank
camshafts, aligning the shafts slightly as necessary.

15. L
oosen 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.

The
teeth of the A-Bank and the B-Bank sprockets on the
crankshaft must be out of phas e with each other. If they
are in-phase after fitting, remo ve the sprocket, turn it on
its vertical axis and refit it.

2. Fi
t the chain tensioning tool 303 - 532 to the exhaust camshaft
sprocket.
Re po
sition the sprocket (and
the VVT unit) for the most
advantageous position for use of the tool.
R e
move the tool.

3. Re
fit 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.
U s
e 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.

14. F
it the VVT bush carrier to the cylinder block.
Lubric

ate the seal (scarf
jointed) and the bush.
1. Fit the bush carrier assembly.
Check that th e seals are in pl ace an
d 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.
Refe
r to the Battery Reconnection Procedure in Section
414-01.

Remove the crankshaft front seal.
1. Install and tighten the removal tool 303-541 to the crankshaft front seal.
2. Tighten the centre bolt of the tool to extract the seal.
R
emove the tool an
d seal assembly.
Separate the seal
from the tool.
12. Very carefully clean the thread s of the crankshaft, using a
plug tap M16x2, to remove all old cured sealant.
Kee
p the tap horizontal. Do not enlarge the crankshaft
thread - remove sealant only.
13. Clean all relevant parts and faces.

1. Loc
ate the new oil seal into the timing cover.
1. Remove the transit ring from the oil seal.
2. Position the seal to the timing cover.

2. Inst
all the new oil seal to the timing cover.
1. Install oil seal replacer tool 303-542 to the oil seal.
2. Use the nut and bolt provided with the tool, to fully seat the seal to the timing cover. Only tighten the nut
sufficiently to locate the seal and no more, or the
timing cover could become distorted.
All
ow the tool to stay in posi
tion against the seal for at
least five seconds.
R
emove the special tool from the seal.

1.
Locate the new oil seal into the timing cover.
1. Remove the transit ring from the oil seal.
2. Position the seal to the timing cover.
2.
Install the new oil seal to the timing cover.
1. Install oil seal replacer tool 303-542 to the oil seal.
2. Use the nut and bolt provided with the tool, to fully seat the seal to the timing cover. Only tighten the nut sufficiently to locate the seal and no more, or the timing cover could become distorted.
 Allow the tool to stay in position against the seal for at least five seconds.
 Remove the special tool from the seal.
3. If the damper is not to be installed immediately, the transit ring should be installed temporarily to the seal.
