INSPECTION
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) Tighten bolts (11) – (20) to 22 N·m (2.2 kg-m, 16.0 lb-ft)
according to numerical order in figure.

Crank shaft bearing cap No.2 bolts (11) – (20)
: 22 N·m (2.2 kg-m, 16.0 lb-ft)

6A1-76 ENGINE MECHANICAL (M13 ENGINE)
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 (uneven wear) 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.
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.
Never replace either half without replacing the other half.
Main bearing clearance
Check clearance by using gaging plastic according to the follow-
ing procedure.
1) Remove bearing caps.
2) Clean bearings and main journals.

ENGINE MECHANICAL (M13 ENGINE) 6A1-77
3) Place a piece of gaging 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.
Tightening torque
Crank shaft bearing No.1 bolts (1) – (10)
: 50 N·m (5.0 kg-m, 36.5 lb-ft) and extra tighten 60°
Crank shaft bearing No.2 bolts (11) – (20)
: 22 N·m (2.2 kg-m, 16.0 lb-ft)
5) Remove bearing caps and using scale (1) on gaging plastic
(2) envelop, measure gaging 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.)
NOTE:
Do not rotate crankshaft while gaging plastic is installed.
NOTE:
After checking main bearing clearance, make sure that
replace bearing cap No.1 bolts new one.

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
2) Next, check bearing cap bore diameter without bearing. On
mating surface of cylinder block, five alphabets are stamped
as shown in figure.
Three kinds of alphabets (“A”, “B” and “C”) represent the fol-
lowing cap bore diameters.
Stamped alphabets on cylinder block represent bearing cap
bore diameter marked with an arrow in figure respectively.
For example, stamped “A” indicates that corresponding bear-
ing cap bore diameter is 49.000 – 49.006 mm (1.9291 –
1.9294 in.).

C 49.012 - 49.018 mm (1.9296 - 1.9298 in.)

ENGINE MECHANICAL (M13 ENGINE) 6A1-79
3) There are five kinds of standard bearings differing in thick-
ness. To distinguish them, they are painted in the following
colors at the position as indicated in figure.
Each color indicated the following thickness at the center of
bearing.
Standard size of crankshaft main bearing thickness
4) From number stamped on crank web No.2 and alphabets
stamped on cylinder block, determine new standard bearing
to be installed to journal, by referring to table shown below.
For example, if number stamped on crank web No.2 is “1”
and alphabet stamped on cylinder block is “B”, install a new
standard bearing painted in “Purple” to its journal.

size
5) Using scale (1) on gaging plastic (2), check bearing clear-
ance with newly selected standard bearing.
If clearance still exceeds its limit, use next thicker bearing
and recheck clearance.
6) When replacing crankshaft or cylinder block due to any rea-
son, select new standard bearings to be installed by referring
to number stamped on new crankshaft or alphabets stamped
on new cylinder block. Color painted Bearing thickness
