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.

NOTE
Ensure that the crankshaft sprocket is installed
with the timing mark (1) visible.
Figure 6A1 – 143
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.

Figure 6A1 – 153
16 Ensure the left-hand secondary timing chain guide is selected and orientated correctly.
CAUTION
The left-hand secondary timing chain guide
is marked with the letters LH. Ensure the
correct shoe is used when installing to the
left-hand side in this procedure and that the
letters ‘LH” are facing the front of the vehicle
when installed.

21 Install the left-hand secondary timing chain shoe
bolt (1) and tighten to the correct torque specification.
NOTE
Ensure secondary timing chain shoe is clear of
the left-hand secondary timing chain tensioner
mounting pad, before tightening the attaching
bolt.
Secondary timing chain shoe attaching
bolt torque specification ..........................20.0 – 26.0 Nm

23 Reset the left-hand secondary timing chain tensioner.
NOTE
To reset the tensioner, use a suitably sized flat
blade screwdriver (1) or Tool No. J 45027 (4) to
wind the plunger in a clockwise direction, into
the tensioner shaft (2).

24 Install the tensioner shaft (1) into the left-hand
secondary timing chain tensioner body (2).
Figure 6A1 – 161
25 Compress the tensioner shaft into the body and lock the left-hand secondary timing chain tensioner by
inserting Tool No. EN 46112 into the access hole in
the side of the tensioner body.
26 Slowly release pressure on the left-hand secondary timing chain tensioner. The tensioner should remain
compressed.
CAUTION
If Tool No. EN 46112 (1) is not removed from
the tensioner body (2), the tensioner
shaft (3) will remain in the locked position
and no tension will be placed on the timing
chain, this will cause damage to the engine.
Figure 6A1 – 162
27 Install a new left-hand secondary timing chain tensioner gasket (1) to the tensioner (2).
28 Install the left-hand secondary timing chain tensioner bolts through tensioner and gasket.
29 Ensure the left-hand secondary timing chain tensioner mounting surface on the left-hand cylinder head does
not have any burrs or defects that would affect the
sealing of the new gasket.
