2 Inspect the tensioner for locked or binding tensioner shaft (2). Reset the plunger (3) and ensure the tensioner shaft
moves freely in and out of the body of the tensioner.
NOTE
To reset the tensioner, use a suitably sized flat
blade screwdriver or Tool No. J 45027 (4) to wind
the plunger in a clockwise direction, into the
tensioner shaft.
3 Replace a damaged tens ioner as required.

Reinstall
Left-hand Secondary Timing Chain Components – Excluding MY06 Update
1 Install the crankshaft sprocket (1) onto the
crankshaft (2) by aligning the keyway to the key on
the crankshaft.
2 Slide the crankshaft sprocket on the crankshaft until the crankshaft sprocket contacts the step in the
crankshaft.
Figure 6A1 – 144
NOTE
Ensure that the crankshaft sprocket is installed
with the timing mark (1) visible.
Figure 6A1 – 145
CAUTION
In order to install Tool No. EN 46105 onto the
camshafts, rotate the camshafts in an anti-
clockwise direction. There should be no
need to rotate the camshaft more than 45
degrees.

left-hand cylinder head camshafts (2), and Tool No.
EN 46105-2 onto the rear of the right-hand cylinder
head camshafts.
4 Ensure that Tool No. EN 46105 is fully seated onto the camshafts.
CAUTION
All camshafts must be locked in place before
installation of any timing chains.

5 Using Tool No. EN46111 (1), rotate the crankshaft in a clockwise direction until the crankshaft sprocket
timing mark (2) is aligned with the indexing mark (3)
on the oil pump housing.

7 Wrap the secondary timing chain around both left-
hand camshaft drive sprockets.
8 Ensure there are two bright links located on top of each of the camshaft sprockets.
Figure 6A1 – 150
CAUTION
When aligning the left-hand secondary timing
chain to the camshaft sprockets, ensure the
circular timing marks on the sprocket are
used, NOT the triangular mark.
9 Align the bright plated timing chain link (1) with the left-hand exhaust camshaft position sprocket
alignment circle mark (2).

CAUTION
The left-hand camshaft intermediate
sprocket (1) is marked with the letters LB
and ‘FRONT’, and the right-hand sprocket (2)
is marked with the letters RB and 'FRONT'
Ensure the correct sprocket is used and the
'FRONT' text is facing forwards when
installed.
