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 – 173
3 Install Tool No. EN 46105-1 (1) onto the rear of the
left-hand cylinder head camshafts (2).
CAUTION
All camshafts must be locked in place before
installation of any timing chains.
4 Ensure that Tool No. EN 46105 is fully seated onto the camshafts.

Figure 6A1 – 174
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.

12 Place the left-hand secondary timing chain around the
left-hand camshaft intermediate inner sprocket, with
the bright plated timing chain link (1) aligned with the
access hole (2) in the outer sprocket.

22 Ensure the left-hand secondary timing chain tensioner
is selected and orientated correctly.

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).

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.
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.

Figure 6A1 – 192
27 Install a new left-hand secondary timing chain tensioner gasket (1) to the tensioner (2).
28 Install the left-hand secondar y 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.

Figure 6A1 – 193
30 Place the left-hand secondar y timing chain tensioner
(2) into position and loosely install the bolts (1) to the
cylinder head.
