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.

Rear Oil Seal
Carefully inspect oil seal (1) for wear or damage.
If its lip is worn or damaged, replace it.
For oil seal installation, press-fit rear oil seal (1) to oil seal hous-
ing (2) by using special tool as shown in the figure.

Flywheel
If ring gear is damaged, cracked or worn, replace flywheel.
If the surface contacting clutch disc is damaged, or exces-
sively worn, replace flywheel.
Check flywheel for face runout with a dial gauge.
If runout exceeds its limit, replace flywheel.

Limit : 0.2 mm (0.0079 in.)
Sensor Plate
Check sensor plate for crack or damage. If malcondition is
found, replace it.
Cylinder Block
Distortion of gasketed surface
Using straightedge and thickness gauge, check gasketed
surface for distortion and, if flatness exceeds its limit, correct
it.
Cylinder block flatness
Limit : 0.05 mm (0.0020 in.)
Honing or reboring cylinders
1) When any cylinder needs reboring, all other cylinders must
also be rebored at the same time.
2) Select oversized piston according to amount of cylinder
wear.

3) Using micrometer, measure piston diameter.
Measurement position for piston diameter
“a” : 19.5 mm (0.77 in.)
4) Calculate cylinder bore diameter to be rebored as follows.
D = A + B – C
D : Cylinder bore diameter to be rebored.
A : Piston diameter as measured.
B : Piston clearance = 0.02 –0.04 mm (0.0008 – 0.0016 in.)
C : Allowance for honing = 0.02 mm (0.0008 in.)
5) Rebore and hone cylinder to calculated dimension.
6) Measure piston clearance after honing.
NOTE:
Before reboring, install all main bearing caps in place
and tighten to specification to avoid distortion of bearing
bores.

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.
