Installation
NOTE
• Use new bearing cap No.1 bolts. They are deformed once they are used because they
are plastic deformation tightening bolts.
• All parts to be insta lled must be perfectly
clean.
• Be sure to oil crankshaft journals, journal bearings, thrust bearings, crankpins,
connecting rod bearings, pistons, piston
rings and cylinder bores.
• Journal bearings, bearing caps, connecting rods, rod bearings, rod bearing
caps, pistons and piston rings are in
combination sets. Do not disturb such
combination and make sure that each part
goes back to where it came from, when
installing.

Crankshaft Thrust Play
1) Measure this play with crankshaft set in cylinder block in the normal manner, that is with thrust
bearing (1) and journal bearing caps installed.
Thickness of crankshaft thrust bearing

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.)
Limit: 0.054 mm (0.0021 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).
