Setting the camshaft timing is required
whenever the camshaft drive system has
been disturbed and the relationship between
any chain and sprocket has been lost. If
required, follow the left-hand secondary
timing chain reinstallation procedure to reset
the camshaft timing.

Remove
Right-hand Secondary Timing Chain
CAUTION
After removing the upper intake manifold, and
spark plugs, plug any openings to prevent dirt
and other contaminants from entering.
1 Remove the engine front cover assembly, refer to 3.15 Front Cover Assembly.
2 Remove the spark plugs to aid crankshaft/engine rotation, refer to Section 6C1-3 Engine Management – V6 –
Service Operations .
3 Install Tool No. EN46111 (1) onto the crankshaft (2).

Figure 6A1 – 103
4 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.
NOTE
Graphic shows 'Early Type' crankshaft sprocket,
'Late Type' similar.

5 After aligning the crankshaft sprocket timing mark,
check that the camshaft flats (1) at the rear of the
right-hand cylinder head are parallel with the
camshaft cover rail (2).
6 If the camshaft flats are not as shown, rotate the crankshaft 360 °.

9 Remove the right-hand secondary timing chain
tensioner bolts (1) and remove the tensioner (2).
NOTE
Take care when removing the tensioner bolts.
The tensioner plunger is subjected to spring
tension and may spring apart during tensioner
removal.

10 Remove the tensioner gaske t (1) from the tensioner
(2) and discard the gasket.
11 Inspect the tensioner m ounting surface on the right-
hand cylinder head for burrs or any defects that would
affect the sealing of a new tensioner gasket.
