Main Bearings InspectionS7RS0B1406038
General Information
• Service main bearings are available in standard size and 0.25 mm (0.0098 in.) undersize, and each of them
has 5 kinds of bearings differing in tolerance.
• Upper half of bearing (1) has oil groove (2) as shown in figure.
Install this half with o il groove to cylinder block.
• Lower half of bearing does not have an oil groove.
Visual Inspection
Check bearings for pitting, scratches, wear or damage.
If any malcondition is foun d, replace both upper and
lower halves. Never replace either half without replacing
the other half.
Main Bearing Clearance
NOTE
Do not rotate crankshaft while gauging
plastic is installed.
Check clearance by using ga uging plastic according to
the following procedure.
1) Remove bearing caps.
2) Clean bearings and main journals.
3) Place a piece of gauging plastic (1) the full width of bearing (parallel to crankshaft) on journal, avoiding
oil hole. 4) Tighten main bearing cap No.1 bolts (a) and main
bearing cap No.2 bolts (b) gradually as follows.
a) Tighten bolts (“1” through “10”) to 30 N ⋅m (3.0
kgf-m, 22.0 lb-ft) according to numerical order in
the figure.
b) In the same manner as in Step a), tighten them to 50 N ⋅m (5.0 kgf-m, 36.5 lb-ft).
c) In the same manner as in Step a), retighten them to 60 °.
d) Tighten bolts (“11” through “18”) to 25 N ⋅m (2.5
kgf-m, 18.0 lb-ft) according to numerical order in
the figure.
Tightening torque
Main bearing cap No.1 bolt (a): 30 Nm (3.0
kgf-m, 22.0 lb-ft), 50 Nm (5.0 kgf-m, 36.5 lb-ft)
and then retighten by turning through 60°
Main bearing cap No.2 bolt (b): 25 N·m (2.5
kgf-m, 18.0 lb-ft)
5) Remove bearing caps and using scale (1) on gauging plastic envelop (2), measure gauging plastic
width at its widest point. If clearance exceeds its
limit, replace bearing. Always replace both upper
and lower inserts as a unit.
A new standard bearing may produce proper
clearance. If not, it will be necessary to regrind
crankshaft journal for use of 0.25 mm undersize
bearing.
After selecting new bearing, recheck clearance.
Main bearing clearance
Standard: 0.021 – 0.041 mm (0.0008 – 0.0016 in.)

Engine Lubrication System
General Description
Engine Lubrication DescriptionS7RS0B1501001
The oil pump is of a trochoid type, and mounted on the
crankshaft. Oil is drawn up through the oil pump strainer
and passed through the pump to the oil filter.
The filtered oil flows into two paths in cylinder block.
The filtered oil is passed to the passage in heat
exchanger and cylinder block to piston cooling valve of
oil gushed to the lower side of piston. In one path, oil reaches the crankshaft journal bearings.
Oil from the crankshaft journal bearings is supplied to
the connecting rod bearings by means of intersecting
passages drilled in the cran
kshaft, and then injected
from the big end of connecting rod to lubricate piston,
rings and cylinder wall.
In the other path oil goes up to the cylinder head and
lubricates valves and camshafts, etc., after passing
through the internal oil way of camshafts.
An oil relief valve is provided on the oil pump. This valve
starts relieving oil pressure when the pressure exceeds
about 350 kPa (3.5 kg/cm
2, 49.8 psi).

Diagnostic Information and Procedures
Oil Pressure CheckS7RS0B1504001
WARNING!
To avoid danger of being burned, do not
touch exhaust system when it is still hot.
NOTE
Prior to checking oil pressure, check the
following.
• Oil level in oil pan
If oil level is low, add oil up to Full level
mark (hole) (1) on oil level gauge referring
to “Engine Oil and Filter Change in Section
0B”.
• Oil quality If oil is discolored or deteriorated, change
it. For particular oil to be used, refer to
“Engine Oil and Filter Change in Section
0B”.
• Oil leaks If leak is found, repair it.
1) Remove front bumper referring to “Front Bumper and Rear Bumper Components in Section 9K”.
2) Remove engine front cover (1).
3) Disconnect oil pressure switch coupler (1).
4) Remove oil pressure swit ch (2) from cylinder block.
5) Install special tools (oil pressure gauge) to vacated threaded hole of oil pressure switch.

6) Start engine and warm engine up to normal operating temperature.
NOTE
Be sure to shift transaxle gear shift lever in
“Neutral” (shift select lever in “P” range for
A/T vehicle), set parking brake and block
drive wheels.
7) After warming up, raise engine speed to 4,000 r/min. and measure oil pressure.
Oil pressure specification
More than 270 kPa (2.7 kg/cm2, 39.8 psi) at 4,000
r/min. (rpm)
8) After checking oil pressure, stop engine and remove oil pressure gauge and attachment.
9) Before reinstalling oil pressure switch (2), be sure to
wrap its screw threads with sealing tape (1) and
tighten switch to specified torque.
NOTE
If sealing tape edge is bulged out from screw
threads of switch, cut it off.
Tightening torque
Oil pressure switch (a): 13 N·m (1.3 kgf-m, 9.5
lb-ft) 10) Start engine and check oil pressure switch for oil
leakage. If oil leakage is found, repair it.
11) Connect oil pressure switch coupler (1).
