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.

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.

Reassemble
CAUTION
As there are no serviceable components
within the oil pump, a disassembled oil pump
must be replaced.
Reinstall
1 Align the oil pump gerotor with the crankshaft flats and fit the oil pump assembly to the engine block.
2 Align the pump body (2) with the mounting holes in the cylinder block.
3 Install the oil pump bolt (1), three places, and tighten to the correct torque specification.
4 Install the primary timing chain, refer to 3.16 Timing Chains, Tensioners, Shoes and Guides.
Oil pump attaching bolt torque
specification ............................................20.0 – 26.0 Nm

3.18 Camshaft Sprocket
CAUTION
Setting the camshaft timing is required
whenever the camshaft drive system is
disturbed to ensure the relationship between
any chain and sprocket is not lost. Even when
only one sprocket is involved, multiple
crankshaft rotations will not produce
conditions where correct timing can be
confirmed.
If required, follow the Left-hand Secondary
Camshaft Chain Components reinstallation
procedure to reset the camshaft timing.
Remove
Right-hand Side
1 Remove the right-hand camshaft cover, refer to 3.12 Camshaft Cover.
2 Remove the camshaft position sensors, refer to 6C1-3 Engine Management – Service Operations.
3 Remove the camshaft position actuator solenoids, refer to 6C1-3 Engine Management – V6 – Service Operations.
4 Remove the crankshaft balancer assembly, refer to 3.13 Crankshaft Balancer Assembly.

2 Install the cylinder head oil gallery expansion
plugs (1).
Figure 6A1 – 299
CAUTION
• Never reuse a valve stem oil seal. Always
use new seals when assembling the
cylinder head.
• Force should only be applied to the valve
spring contact area of the new valve stem
oil seal during installation.
3 Fit the valve stem oil seals onto the guides using Tool No. EN-46116 (1).
4 Push and twist the valve stem oil seal into position on the valve guide until the seal positively locks on the
guide using Tool No. EN-46116.
5 Lubricate the valve stem and valve guide ID with clean engine oil.
Figure 6A1 – 300
CAUTION
The valve stem oil seal must not come loose
from the valve guide when the valve (1) is
installed.
6 Insert the valve into the valve guide until it bottoms on the valve seat.
