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.

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.

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 Inspect the back of each sprocket for the following:
• Sprocket damage (1),
• Camshaft locating pin damage (2) and,
• Camshaft seating/sealing inner hub flange
damage (3),


NOTE
These checks apply to both the inlet and
exhaust camshaft sprockets.
Figure 6A1 – 237
Reinstall
Reinstallation of the camshaft sprockets is the reverse of the removal procedure, noting the following:
1 Align the sprockets and timing chain with the marks made during removal.
2 Tighten the camshaft sprocket bolts to the correct torque specification.

Remove
Right-hand Side
1 Remove the right-hand cylinder head camshaft sprockets, refer to 3.18 Camshaft Sprocket.
2 Remove the Tool No. EN-46105 – 1 (1) from the right- hand cylinder head camshafts (2).



NOTE
Tool No. EN-46105 was installed as part of the
right-hand cylinder head camshaft sprocket
removal procedure.

1 Select the correct camshaft for the particular installation location. ID markings can be found on the
rear end of each camshaft. The ID markings are
defined as follows:
• The first five digits refer to the date and time of
production.
• Example = 3L18H.
• Digits six through nine refer to engine
production code.
• LY7 = Alloytec 190 engine.
• The last two digits refer to position:
• LI = left-hand intake.
• LE = left-hand exhaust.
• RI = right-hand intake.
• RE = right-hand exhaust.
