LUBRICATION
DESCRIPTION
A gear driven gerotor type oil pump is mounted behind the front gear cover inthe lower right portion on the engine.
OPERATION
A gerotor style oil pump draws oil from the crankcase through the suction tube and delivers it through the block
where it enters the oil cooler cover and pressure regulator valve. When oilpressure exceeds 517 kPa (75 PSI), the
valve opens exposing the dump port, which routes excess oil back to the oil pump.
At the same time, oil is directed to a cast in passage in the oil cooler cover,leading to the oil cooler element. As the
oil travels through the element plates, it is cooled by engine coolant traveling past the outside of the plates. It is
then routed to the oil filter head and through a full flow oil filter. If a plugged filter is encountered, the filter by-pass
valve opens, allowing unfiltered oil to lubricate the engine. This condition can be avoided by frequent oil and filter
changes, per the maintenance schedules found in the owners manual. The by-pass valve is calibrated to open when
it sees a pressure drop of more than 345 kPa (50 psi) across the oil filter.
The oil filter head then divides the oil between the engine and the turbocharger. The turbocharger receives filtered,
cooled and pressurized oil through a supply line from the filter head. The oil lubricates the turbocharger and returns
to the pan by way of a drain tube connecting the bottom of the turbocharger toa tube in the cylinder block.

Oil is then carried across the block toan angle drilling which intersects the main oil rifle (3). The main oil rifle (3)
runs the length of the block and delivers oil to the crankshaft main journals and valve train. Oil travels to the crank-
shaft through a series of transfer drillings (one for each main bearing) and lubricates a groove in the main bearing
upper shell. From there another drilling feeds the camshaft main journals. J-jet piston cooling nozzles (1,4) are sup-
plied by a separate oil rifle. Plugs are used in place of saddle jets when J-jets are used. Crankshaft internal cross-
drillings supply oil to the connecting rod journals.

housing cover and front of the gear housing.
INSPECTION
Disassemble and inspect the oil pump as follows:
1. Visually inspect the lube pump gears for chips,
cracks or excessive wear.
2. Remove the back plate (1).
3. Mark TOP on the gerotor planetary (3) using a felt
tip pen.
4. Remove the gerotor planetary (3) inspect for
excessive wear or damage. Inspect the pump
housing and gerotor drive (2) for damaged and
excessive wear.
5. Install the gerotor planetary in the original position.
6. Measure the tip clearance (1). Maximum clearance
is 0.1778 mm (0.007 inch). If the oil pump is out of
limits, replace the pump.

7. Measure the clearance of the gerotor drive/gerotor
planetary (2)to port plate (1). Maximum clearance
is 0.127 mm (0.005 inch). If the oil pump is out of
limits, replace the pump.

piston number 1 is at TDC.
5. With cylinder number still at TDC, inspect the keyway on the crankshaft gear for proper alignment (12 o’clock
position).
6. If the keyway is not at 12 o’clock position replace the crankshaft gear assembly.
7. If the keyway is at 12 o’clock position, remove front gear cover and verify timing mark alignment between the
camshaft gear and crankshaft gear, if not aligned inspect keyway on camshaft gear.
8. Inspect keyway on camshaft gear for proper alignment with the key in the camshaft, if alignment is off replace
the camshaft/gear assembly.
9. If timing marks alignment is off and no damage is found at either the crankshaft or camshaft gear keyways,
realign timing marks as necessary.
