RINGS - PISTON
STANDARD PROCEDURE - PISTON RING FITTING
Before reinstalling used rings or installing new rings,
the ring clearances must be checked.
1. Wipe the cylinder bore clean.
2. Insert the ring in the cylinder bore.
NOTE: The ring gap measurement must be made
with the ring positioned at least 12mm (0.50 inch.)
from bottom of cylinder bore.
3. Using a piston, to ensure that the ring is squared in
the cylinder bore, slide the ring downward into the
cylinder.
4. Using a feeler gauge (1) check the ring end gap.
Replace any rings not within specification.
PISTON RING SIDE CLEARANCE
NOTE: Make sure the piston ring grooves are
clean and free of nicks and burrs.
5. Measure the ring side clearance as shown make sure the feeler gauge (1) fits snugly between the ring land and
the ring. Replace any ring not within specification.
6. Rotate the ring around the piston, the ring must rotate in the groove without binding.

7. The No. 1 and No. 2 piston rings have a different
cross section. Ensure No. 2 ring is installed with
manufacturers I.D. mark (Dot) facing up, towards
top of the piston.
NOTE: Piston rings are installed in the following
order:
Oil ring expander.
Upper oil ring side rail.
Lower oil ring side rail.
No. 2 Intermediate piston ring.
No. 1 Upper piston ring.
8. Install the oil ring expander.
9. Install upper side rail (1) by placing one end
between the piston ring groove and the expander
ring. Hold end firmly and press down the portion to
be installed until side rail is in position. Repeat this step for the lower side rail.

LUBRICATION
DESCRIPTION
The lubrication system is a full flow filtration pressure feed type.
OPERATION
Oil from the oil pan is pumped by a gerotor type oil pump directly mounted to the crankshaft nose. Oil pressure is
controlled by a relief valve mounted inside the oil pump housing.
The camshaft exhaust valve lobes and rocker arms are lubricated through a small hole in the rocker arm; oil flows
through the lash adjuster then through the rocker arm and onto the camshaftlobe. Due to the orentation of the
rocker arm, the camshaft intake lobes are not lubed in the same manner as theexhaust lobes. The intake lobes are
lubed through internal passages in the camshaft. Oil flows through a bore in the number 3 camshaft bearing bore,
and as the camshaft turns, a hole in the camshaft aligns with the hole in the camshaft bore allowing engine oil to
enter the camshaft tube. The oil then exits through 1.6mm (0.063 in.) holesdrilled into the intake lobes, lubricating
the lobes and the rocker arms.

lobes, which have oil passages drilled into them to lubricate the rocker arms.
DIAGNOSIS AND TESTING
DIAGNOSIS AND TESTING - CHECKING ENGINE OIL PRESSURE
1. Remove oil pressure sending unit (2) and install
gauge assembly C-3292.
2. Run engine until thermostat opens.
3. Oil Pressure:
Curb Idle - 25 kPa (4 psi) minimum
3000 rpm - 170 - 758 kPa (25 - 110 psi)
4. If oil pressure is 0 at idle, shut off engine. Check
for a clogged oil pick-up screen or a pressure relief
valve stuck open.
