INSPECTION
Main bearing cap No.1 bolt
Measure each thread diameter of bearing cap No.1 bolts (1) at
“A” on 60 mm (2.36 in.) from seat side of flange bolt and “B” on 90
mm (3.54 in.) from seat side of flange bolt by using a micrometer
(2).
Calculate difference in diameters (“A” – “B”).
If it exceeds limit, replace with new one.
Bearing cap No.1 bolt diameter measurement points
“a” : 60 mm (2.36 in.)
“b” : 90 mm (3.54 in.)
Bearing cap No.1 bolt diameter difference
Limit (“A” – “B”) : 0.2 mm (0.008 in.)
Crankshaft
Crankshaft runout
Using a dial gauge, measure runout at center journal. Rotate
crankshaft slowly. If runout exceeds its limit, replace crankshaft.
Crankshaft runout
Limit : 0.04 mm (0.0016 in.)
Crankshaft thrust play
Measure this play with crankshaft set in cylinder block in the nor-
mal manner, that is with thrust bearing (1) and journal bearing
caps installed.
Thickness of crankshaft thrust bearing
Standard : 2.500 mm (0.0984 in.)
Oversize (0.125 mm (0.0049 in.)) : 2.563 mm (0.1009 in.)

Tighten bearing cap No.1 bolts (1) – (10) and No.2 bolts (11) –
(20) gradually as follows.
1) Tighten bolts (1) – (10) to 30 N·m (3.0 kg-m, 22.0 lb-ft)
according to numerical order in figure.
2) In the same manner as in Step 1), tighten them to 50 N·m
(5.0 kg-m, 36.5 lb-ft).
3) In the same manner as in step 1), retighten them to 60°.
4) Tighten bolts (11) – (20) to 22 N·m (2.2 kg-m, 16.0 lb-ft)
according to numerical order in figure.
Tightening torque
Crankshaft bearing cap No.1 bolts (1) – (10) :

Crankshaft bearing cap No.2 bolts (11) – (20) :
22 N·m (2.2 kg-m, 16.0 lb-ft)
Use a dial gauge to read displacement in axial (thrust) direction of
crankshaft.
If its limit is exceeded, replace thrust bearing with new standard
one or oversize one to obtain standard thrust play.
Crankshaft thrust play
Standard : 0.11 – 0.31 mm (0.0043 – 0.0122 in.)
Limit : 0.35 mm (0.0138 in.)
Out-of-round and taper of journals
An unevenly worn crankshaft journal shows up as a difference in
diameter at a cross section or along its length (or both). This dif-
ference, if any, is determined by taking micrometer readings. If
any one of journals is badly damaged or if amount of uneven
wear in the sense explained above exceeds its limit, regrind or
replace crankshaft.

Main Bearings
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.
NOTE:
After checking the thrust play, check for thread deforma-
tion of each bearing cap No.1 bolt according to previous
mentioned “Main Bearing Cap No.1 Bolt” once again.

Upper half of bearing (1) has an 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.
Do not replace either half without replacing the other half.
Main bearing clearance
Check clearance by using gauging plastic according to the follow-
ing 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 bearing cap No.1 bolts (1) – (10) and No.2 bolts (11)
– (20) gradually as follows.
a) Tighten bolts (1) – (10) to 30 N·m (3.0 kg-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 kg-m, 36.5 lb-ft).
c) In the same manner as in step a), retighten them to 60°.
d) Tighten bolts (11) – (20) to 22 N·m (2.2 kg-m, 16.0 lb-ft)
according to numerical order in figure.

NOTE:
Do not rotate crankshaft while gauging plastic is
installed.

5) Remove bearing caps and using scale (1) on gauging plastic
(2) envelop, 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 : 0.025 – 0.045 mm (0.0010 – 0.0018 in.)
Limit : 0.065 mm (0.0026 in.)
Selection of main bearings
STANDARD BEARING:
If bearing is in malcondition, or bearing clearance is out of specifi-
cation, select a new standard bearing according to the following
procedure and install it.
1) First check journal diameter. As shown in figure, crank web
No.2 has stamped numbers.
Three kinds of numbers (“1”, “2” and “3”) represent the fol-
lowing journal diameters.
Stamped numbers on crank web No.2 represent journal
diameters marked with an arrow in figure respectively.
For example, stamped number “1” indicates that correspond-
ing journal diameter is 44.994 – 45.000 mm (1.7714 –
1.7717 in.).
Crankshaft journal diameter NOTE:
After checking the bearing clearance, check for thread
deformation of each bearing cap No.1 bolt according to
previous mentioned Step 4) once again.
