PISTON-TO-BORE CLEARANCENJEM0026S061. Using a bore gauge, measure cylinder bore for wear, out-of-
round and taper.
Standard inner diameter:
Refer to SDS, EM-73.
Wear limit:
0.2 mm (0.008 in)
Out-of-round (X þ Y) standard:
Less than 0.015 mm (0.0006 in)
Taper (A þ B) standard:
Less than 0.01 mm (0.0004 in)
If it exceeds the limit, rebore all cylinders. Replace cylinder
block if necessary.
2. Check for score and seizure. If seizure is found, hone it.
+If cylinder block or piston is replaced, match piston grade
with grade number on cylinder block lower surface.
SEM258C
3. Measure piston skirt diameter.
Piston diameter ªAº:
Refer to SDS, EM-74.
Measuring point ªaº (Distance from the top):
Refer to SDS, EM-74.
4. Check that piston-to-bore clearance is within specification.
Piston-to-bore clearance = cylinder bore measurement
ªBº þ Piston diameter ªAº:
Refer to SDS, EM-74.
5. Determine piston oversize according to amount of cylinder
wear.
Oversize pistons are available for service. Refer to SDS EM-74.
6. Cylinder bore size is determined by adding piston-to-bore
clearance to piston diameter ªAº.
Rebored size calculation:
D=A+BþC
where,
D: Bored diameter
A: Piston diameter as measured
B: Piston-to-bore clearance
C: Honing allowance 0.02 mm (0.0008 in)
7. Install main bearing caps and tighten bolts to the specified
torque. This will prevent distortion of cylinder bores.
8. Cut cylinder bores.
+When any cylinder needs boring, all other cylinders must
also be bored.
+Do not cut too much out of cylinder bore at a time. Cut
only 0.05 mm (0.0020 in) or so at a time.
9. Hone cylinders to obtain specified piston-to-bore clearance.
10. Measure finished cylinder bore for out-of-round and taper.
+Measurement should be done after cylinder bore cools
down.

When grinding crank pin and crank journal:
+Grind until clearance is within specified standard bearing
clearance.
+Fillets should be finished as shown in the figure. R: 2.3 -

6. If the crankshaft 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.
AEM172
SEM194C
b. Grade number of each crankshaft main journal is punched on
the respective crankshaft. These numbers are punched in
either Arabic or Roman numerals.
c. Select main bearing with suitable thickness according to the
following table.
Main bearing grade color:
Crankshaft main jour-
nal grade numberCylinder block main journal grade number

1 Brown or Red Green Yellow
2 Green Yellow Blue
For example:
Cylinder block main journal grade number: 1

the specified torque.
+Apply new engine oil to the bolt thread and seat surface.
+Prior to tightening bearing cap bolts, shift crankshaft back
and forth to properly seat the bearing caps.
+Tighten bearing cap bolts gradually in two or three stages.
Start with center bearing and move outward as shown in
figure.
+After securing bearing cap bolts, make sure crankshaft
turns smoothly by hand.

4. Measure crankshaft end play.
Crankshaft end play:
Standard
0.060 - 0.220 mm (0.0024 - 0.0087 in)

to 11.566 ft-lb).
+Turn nuts to 35É to 40É degrees clockwise with an angle
wrench. If an angle wrench is not available, tighten nuts to
