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.)

bleed valve (4) of the thermostat (5).
• Use new O-rings when installing.
• Adjust water pump belt tension referring to “Water Pump / Generator Drive Belt Tension Inspection and
Adjustment in Section 1J”.
• Adjust A/C compressor belt tension referring to “Compressor Drive Belt Inspection and Adjustment in
Section 7B” or “Compressor Drive Belt Inspection and
Adjustment in Section 7B”. • Refill cooling system referrin
g to Step 7) to 22) of
“Cooling System Flush and Refill”.
• Verify that there is no coolant leakage at each connection.
Thermostat InspectionS7RS0B1606008
• Make sure that air bleed valve (1) of thermostat is clean.
• Check to make sure that va lve seat (2) is free from
foreign matters which would prevent valve from
seating tight.
• Check thermostat seal (3) for breakage, deterioration or any other damage.
• Check thermostatic movement of wax pellet as follows:
a. Immerse thermostat (1) in water, and heat water gradually.
b. Check that valve starts to open at specific temperature.
Temperature at which valve begins to open
80 – 84 °C (176 – 183 °F)
Temperature at which valve become fully open
95 – 97 °C (203 °F)
Va l v e l i ft
More than 8 mm at 95 °C (203 ° F)
If valve starts to open at a temperature substantially
below or above specific temperature, thermostat unit
should be replaced with a new one. Such a unit, if
reused, will bring about ov ercooling or overheating
tendency.

Engine
Ignition System
General Description
Ignition System ConstructionS7RS0B1801001
The ignition system is an electronic (distributorless) ignition system. It consists of the parts as described below.
• ECM
It detects the engine and vehicle conditions through the si gnals from the sensors, determines the most suitable
ignition timing and time for electricity to flow to the primar y coil and sends a signal to the ignitor (power unit) in the
ignition coil assembly.
• Ignition coil assembly (including an ignitor)
The ignition coil assembly has a built -in ignitor which turns ON and OFF the current flow to the primary coil
according to the signal from ECM. When the current flow to the primary coil is turned OFF, a high voltage is induced
in the secondary coil.
• High-tension cords and spark plugs
• CMP sensor (Camshaft position sensor) and CKP sensor (Crankshaft position sensor)
Using signals from these sensors, ECM identifies the specific cylinder whose piston is in the compression stroke,
detects the crank angle and adjusts in itial ignition timing automatically.
• TP sensor, ECT sensor, MAP sensor, MAF sensor, IAT sensor, knock sensor and other sensors / switches
Although this ignition system does not have a distributor, it has two ignition coil assemblies (one is for No.1 and No.4
spark plugs and the other is for No.2 and No.3 spark plugs). W hen an ignition signal is sent from ECM to the ignitor in
the ignition coil assembly for No.1 and No.4 spark plugs, a high voltage is induced in the secondary coil and that
passes through the high-tension cords and causes No.1 and No.4 spark plugs to spark simultaneously. Likewise,
when an ignition signal is sent to the ignitor in the ot her ignition coil assembly, No.2 and No.3 spark plugs spark
simultaneously.

Charging System Circuit
The generator features solid state regulator that it mounted inside the generator. All regulator components are
enclosed into a solid mold, and this unit along with the brus h holder assembly is attached to the rear housing. The
regulator voltage is being controlled by ECM under some cond itions while driving. Refer to “Generator Control System
Description in Section 1A”.
The generator rotor bearings contain enough grease to eliminate the need for periodic lubrication.
Two brushes carry current through the two slip rings to the field coil mounted on the rotor, and under normal conditions
will provide long period of attention-free service.
The stator windings are assembled inside a laminate d core that forms part of the generator frame.
A rectifier bridge connected to the stator windings contains diodes, and electrically changes the stator AC. voltages to
a D.C. voltage which appears at the generator output terminal.

• Inspect strut for oil leakage, damage or deformation.
• If defect is found, replace strut as an assembly unit, because it can not be disassembled.
• Inspect strut function re ferring to the following
procedures:
1) Check and adjust tire pressures as specified.
2) Bounce vehicle body up and down 3 or 4 times continuously by pushing front end of the vehicle side
body to check strut.
Also, note how many times vehicle body rebounds to
stop after force application.
3) Repeat the same procedure to the other strut to confirm that the both side struts equally respond.
If conditions of struts are in doubt, compare them with
known-good vehicle or strut.
• Inspect bearing for wear, abnormal noise or gripping. If defective, replace.
• Inspect coil spring seat for cracks or deformation.
If defective, replace.
• Inspect bump stopper for deterioration. If defective, replace.
• Inspect rebound stopper and strut mount for wear, cracks or deformation.
If defective, replace.
