Main Bearings InspectionS6RW0D1406040
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 oil 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 found, 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 gauging 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 (1) – (10) and
main bearing cap No.2 bolts (11) – (20) gradually as
follows.
a) Tighten bolts (1) – (10) to 30 N⋅m (3.0 kgf-m,
22.0 lb-ft) according to numerical order in 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) – (20) to 25 N⋅m (2.5 kgf-m,
18.0 lb-ft) according to numerical order in figure.
Tightening torque
Main bearing cap No.1 bolt ((1) – (10)):
Tighten 30 N⋅m (3.0 kgf-m, 22.0 lb-ft), 50 N⋅m
(5.0 kgf-m, 36.5 lb-ft) and 60° by the specified
procedure
Main bearing cap No.2 bolt ((11) – (20)):
Tighten 25 N⋅m (2.5 kgf-m, 18.0 lb-ft) by the
specified procedure
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.)
Limit: 0.054 mm (0.0021 in.)

Engine Lubrication System
General Description
Engine Lubrication DescriptionS6RW0D1501001
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.
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 crankshaft, 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
specified pressure.

Diagnostic Information and Procedures
Oil Pressure CheckS6RW0D1504001
WARNING!
To avoid the danger of being burned, do not
touch the exhaust system when the system is
hot. Any service on the exhaust system
should be performed when the system is
cool.

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) Disconnect oil pressure switch coupler (1).
2) Remove oil pressure switch (2) from cylinder block.3) Install special tools (oil pressure gauge) to vacated
threaded hole of oil pressure switch.
Special tool
(A): 09915–77310
(B): 09915–78211
4) Start engine and warm engine up to normal
operating temperature.
NOTE
Be sure to shift transaxle gear shift lever in
“Neutral”, set parking brake and block drive
wheels.

5) After warming up, raise engine speed to 4,000 r/min.
and measure oil pressure.
Oil pressure specification
More than 270 kPa (2.7 kgf/cm2, 39.8 psi) at 4,000
r/min. (rpm)
6) After checking oil pressure, stop engine and remove
oil pressure gauge and attachment.
7) 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.
