2. Install main bearing cap to cylinder block.
lTighten all bolts in correct order in two or three stages.
Refer to EM-2038 and EM-2046.
3. Measure inner diameter ªAº of each main bearing.
4. Measure outer diameter ªDmº of each crankshaft main jour-
nal.
5. Calculate main bearing clearance.
Main bearing clearance=AþDm
Standard:
0.020 - 0.047 mm (0.0008 - 0.0019 in)
Limit:
0.1 mm (0.004 in)
6. If it exceeds the limit, replace bearing.
7. If clearance cannot be adjusted within the standard of any
bearing, grind crankshaft journal and use undersized bear-
ing.
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, EM-2055 & EM-2056 for grinding crank-
shaftandavailable service parts.
8. If crankshaft is reused, measure main bearing clearance and
select thickness of main bearing.
If crankshaft or cylinder block is replaced, 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 Roman numerals.

3. Measure crankshaft end play.
Crankshaft end play:
Standard
0.05 - 0.18 mm (0.0020 - 0.0071 in)
Limit
0.3 mm (0.012 in)
If beyond the limit, replace No. 3 bearing with a new one.
4. Install connecting rod bearings in connecting rods and con-
necting rod caps.
lConfirm that correct bearings are used.
Refer to EM-2044.
lInstall bearings so that oil hole in connecting rod aligns
with oil hole of bearing.
lApply new engine oil to bearing surfaces, bolt threads
and seating surfaces.
5. Install pistons with connecting rods.
a. Install them into corresponding cylinders with Tool.
lArrange so that front mark on piston head faces toward
front of engine.
lMake sure connecting rod does not scratch cylinder
wall.
lMake sure connecting rod bolts do not scratch crank-
shaft journals.
lApply new engine oil to piston rings and sliding surface
of piston.
b. Install connecting rod bearing caps.
Tighten connecting rod bearing cap nuts using the following
procedure.
Connecting rod bearing nut:
(1) Tighten to 14 to 16 Nzm
(1.4 to 1.6 kg-m, 10 to 12 ft-lb).
(2) Tighten bolts 60
+5
þ0degrees clockwise
with an angle wrench.
If an angle wrench is not available, tighten
them to 38 to 44 Nzm (3.9 to 4.5 kg-m, 28 to 33
ft-lb).
6. Measure connecting rod side clearance.
Connecting rod side clearance:
Standard
0.2 - 0.4 mm (0.008 - 0.016 in)
Limit
0.6 mm (0.024 in)
If beyond the limit, replace connecting rod and/or crankshaft.

If no malfunction is detected on ``SELF-DIAG [CURRENT]'' even
though malfunction is detected by the ``AIR BAG'' warning lamp,
check the battery voltage.
If the battery voltage is less than 9V, charge the battery. Then
go to DIAGNOSTIC PROCEDURE 4 for final checking, page
RS-2030.
If the battery voltage is OK, go to DIAGNOSTIC PROCEDURE
6, page RS-2034, to diagnose the following situations:
lSelf-diagnostic result (previously stored in the memory)
might not be erased after repair.
lThe SRS system malfunctions intermittently.
8. Touch ``PRINT''.
9. Compare diagnostic codes to the CONSULT DIAGNOSTIC
CODE CHART, page RS-2028.
10. Touch ``BACK'' key of CONSULT until ``SELECT SYSTEM''
appears in order to return to User mode from Diagnosis
mode, then turn off CONSULT.
11. Turn ignition switch ``OFF'', then disconnect CONSULT and
both battery cables.
12. Repair the system as outlined by the ``Repair order'' in CON-
SULT DIAGNOSTIC CODE CHART, that corresponds to the
self-diagnostic result. For replacement procedure of compo-
nent parts, refer to RS-2007.
13. After repairing the system, go to DIAGNOSTIC PROCE-
DURE 4 for final checking, page RS-2030.SRS049
