8 Align the bright plated timing chain link (2) with the exhaust actuator sprocket alignment triangle mark or
circular mark .
CAUTION
Ensure that when aligning the right-hand
secondary timing chain to the right-hand
camshaft actuator sprockets, that the
triangular timing marks (1) on the sprocket
are used, NOT the circular mark.

10 Ensure that the right-hand secondary timing chain guide is selected and orientated correctly.
CAUTION
Ensure that the right-hand secondary timing
chain guide is used when installing to the
right-hand side in this procedure.

13 Ensure the right-hand secondary timing chain shoe is selected and orientated correctly.
CAUTION
The right-hand secondary camshaft drive
shoe is marked with the letters ‘RH’. Ensure
that the right-hand drive shoe is used when
installing to the right-hand side in this
procedure and that the letters ‘RH” are
facing the front of the vehicle when installed.

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

18 Install the tensioner shaft (1) into the right-hand
secondary timing chain tensioner body (2).
Figure 6A1 – 205
19 Compress the tensioner shaft into the body and lock the tensioner by inserting Tool No. EN 46112 into the
access hole in the side of the tensioner body.
20 Slowly release pressure on the right-hand secondary timing chain tensioner. The tensioner should remain
compressed.

21 Install a new right-hand secondary timing chain tensioner gasket (1) to the tensioner (2).
22 Install the right-hand secondary timing chain tensioner bolts (3) through the tensioner and gasket.
23 Ensure the right-hand secondary timing chain tensioner mounting surface on the right-hand cylinder
head does not have any burrs or defects that would
affect the sealing of the new tensioner gasket.

24 Place the right-hand secondary timing chain tensioner
(2) into position and loosely install the bolts (1) to the
engine block.

27 Release the right-hand timing chain tensioner (1) by pulling out Tool No. EN 46112 (2) and unlocking the
tensioner plunger.
CAUTION
If Tool No. EN 46112 (1) is not removed from
the tensioner body (2), the plunger will
remain in the locked position and no tension
will be placed on the timing chain, this will
cause damage to the engine.

Disassemble
CAUTION
There are no serviceable components within
the oil pump. Disassemble the pump only to
diagnose an oil related concern. A
disassembled oil pump must not be reused: it
must be replaced.
1 Remove the two bolts (1) attaching the primary timing chain lower guide (2) and remove the guide.
CAUTION
The primary timing chain lower guide is not
serviced separately and is part of the oil
pump assembly. If it is removed from the
pump assembly, the guide and the pump
must be replaced.
