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.

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 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.

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.

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
bearing cap bore diameter is 49.000 – 49.006 mm (1.9291 –
1.9294 in.).

3) There are five kinds of standard bearings differing in thick-
ness. To distinguish them, they are painted in the following
colors at the center of bearings.
Each color indicates the following 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.

5) Using scale (1) on gauging 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.
UNDERSIZE BEARING (0.25 mm):
0.25 mm undersize bearing is available, in five kinds varying
in thickness.
To distinguish them, each bearing is painted in the following
colors at the center of bearing.
Each color represents the following thickness.

If necessary, regrind crankshaft journal and select undersize
bearing to use with it as follows.
a) Regrind journal to the following finished diameter.
Finished diameter
44.732 – 44.750 mm (1.7611 – 1.7618 in.)
1) Using micrometer, measure reground journal diameter.
Measurement should be taken in two directions perpendicu-
lar to each other in order to check for out-of-round.
2) Using journal diameter measured above and alphabets
stamped on cylinder block, select an undersize bearing by
referring to table given below.
Check bearing clearance with newly selected undersize
bearing.

INSTALLATION
1) Install sensor plate (1) to crankshaft (2) and tighten bolts to
specified torque.
Tightening torque
Sensor plate bolts (a) : 11 N·m (1.1 kg-m, 8.0 lb-ft)
2) Install main bearings to cylinder block.
Upper half of bearing (1) has an oil groove (2).
Install it to cylinder block (3), and the other half without oil
groove to bearing cap.
Make sure that two halves are painted in the same color.
3) Install thrust bearings (1) to cylinder block between No.2 and
No.3 cylinders. Face oil groove (2) sides to crank webs.
4) Confirm that dowel pins(3) are installed to intake side of
each journal. NOTE:
All parts to be installed must be perfectly clean.
Be sure to oil crankshaft journals, journal bearings,
thrust bearings, crankpins, connecting rod bearings,
pistons, piston rings and cylinder bores.
Journal bearings, bearings caps, connecting rods, rod
bearings, rod bearing caps, pistons and piston rings
are in combination sets. Do not disturb such combina-
tion and make sure that each part goes back to where
it came from, when installing.
NOTE:
When installing sensor plate, align spring pin (3) on
crankshaft and hole of sensor plate.
