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.
Figure 6A1 – 213
2 Remove the seven bolts (2) attaching the oil pump cover to the oil pump housing (1) and remove the
cover from the housing.

3 Remove the inner gerotor ring (1).
4 Remove the outer gerotor ring (2).

Figure 6A1 – 215
5 Remove the clip (1), retaining the oil relief valve cap (2).
6 Remove the cap, spring (3) and plunger (4) from the oil pump housing.

Figure 6A1 – 216
Clean
1 Clean the oil pump components with non-corrosive solvent.

Safety glasses must be worn when using
compressed air.
2 Dry the oil pump components with compressed air.

Inspect
1 Inspect the oil pump housing for damage.
Figure 6A1 – 217
2 Inspect the oil pump cover for damage.

Figure 6A1 – 218
3 Inspect the inner drive gear for damage. If inner surface damage is found, ensure the crankshaft is
also inspected.

4 Inspect the outer driven gear for damage.

Figure 6A1 – 220
5 Inspect the oil pump relief valve components for debris or damage.

Figure 6A1 – 221
6 Inspect the primary camshaft chain lower guide for damage. If replacement of the primary camshaft chain
lower guide is required, replace the entire oil pump
assembly as the primary camshaft chain lower guide
is not serviceable separately.
7 If debris or damage is present within the oil pump, further inspection of all of the engine components is
required.

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.

8 Place the dial indicator tip on the base circle (1) of the
camshaft lobe.
9 Set the dial indicator at zero.
10 Rotate the camshaft until the indicator tip is at the highest point (2) on the lobe. This reading is the lift of
the camshaft lobe.

Reinstall
Right-hand Side
1 Select the correct camshaft for the particular installation location. ID markings are 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.

2 Apply a liberal amount of engine oil to the camshaft (1) journals and the right-hand cylinder
head camshaft carriers (2).
