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-72.
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-73.
Measuring point ªaº (Distance from the top):
Refer to SDS, EM-73.
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-73.
5. Determine piston oversize according to amount of cylinder
wear.
Oversize pistons are available for service. Refer to SDS EM-73.
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.
