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

24 Install the tensioner shaft (1) into the left-hand
secondary timing chain tensioner body (2).

Figure 6A1 – 164
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.

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.
