2. Install main bearing cap and bearing beam to cylinder block.
Tighten all bolts in correct order.
3. Measure inner diameters ªAº of each main bearing.
AEM033
4. Measure outer diameters ªDmº of each crankshaft main jour-
nal.
5. Calculate main bearing clearance.
Main bearing clearance = A þ Dm
Standard: 0.035 - 0.045 mm (0.0014 - 0.0018 in)
Limit: 0.065 mm (0.0026 in)
IIf it exceeds the limit, replace bearing.
IIf clearance cannot be adjusted using any standard bearing
grade, grind crankshaft journal and use undersized bearing.

a. When grinding crankshaft journal, confirm that ªLº dimension in
fillet roll is more than the specified limit.
ªLº: 0.1 mm (0.004 in)
b. Refer to SDS for grinding crankshaft and available service
parts.

6. If crankshaft or cylinder block is replaced with a new one,
select thickness of main bearings as follows:
a. Grade number of each cylinder block main journal is punched
on the respective cylinder block. These numbers are punched
in either Arabic or Alphabet. Refer to SDS, EM-81.
If measured diameter is out of grade punched, decide suitable
grade using table in SDS.
SEM452G
b. Grade number of each crankshaft main journal is punched on
the respective crankshaft. These numbers are punched in
either Arabic or Alphabet. Refer to SDS, EM-84.
If measured diameter is out of grade punched, decide suitable
grade using table in SDS.
c. Select main bearing with suitable thickness according to the
following table.
Refer to ªSDSº, EM-85, for available main bearings.

Trouble Diagnoses with
Battery/Starting/Charging System Tester
NBSC0020NOTE:
To ensure a complete and thorough diagnosis, the battery, starter
and alternator test segments must be done as a set from start to
finish.
SEL417X
1. Turn off all loads on the vehicle electrical system.
2. Perform battery and starting system test with Battery/Starting/
Charging system tester.
3. Press ªENTERº to begin the charging system test.
4. Start engine.
SEL418X
5. Press ªENTERº until ªLOADS OFF REV ENGINE 5 SECº is
displayed.
6. Raise and hold the engine speed at 1,500 to 2,000 rpm for
about 5 seconds, then return to the engine to idle.
Once the increase in engine rpm is detected, press ªENTERº
to continue.
NOTE:
IIf after 30 seconds an increase in engine idle speed is not
detected, ªRPM NOT DETECTEDº will display.
ISome engines may have a higher idle initially after starting,
particularly when the engine is cold. The tester may detect this
without any other action being taken. If this occurs, continue on
with the testing process. The final results will not be affected.
SEL419X
7. The tester now checks the engine at idle and performs the
DIODE/RIPPLE check.
8. When complete, the tester will prompt you to turn on the fol-
lowing electrical loads.
IHeater fun set to highest. Do not run the A/C or windshield
defroster.
