Selection of Piston Grade
See the piston diameter and the cylinder liner
combination about "pistion grade".
Correctly selected the pistion grade does
operate efficiency of engine to be protected
cylinder liner and piston.
Meassure the bore after assemble the cylinder
liner.
Determine piston grade after assemble liner.
• Measurement of Cylinder Liner Bore
1) To be measured 2 points.
Cylinder Liner Measuring Point : 20mm
Cylinder Liner Measuring Point : 105mm
2) Measure cylinder liner from (1), (2) & (3)
measuring point toward X-X, Y-Y, W-W, Z-Z.
3) Average value for 8 measurements.
Limit of Cylinder Liner Bore
102.021-102.060 mm
CAUTION
It is most important to be
correctly graded combination.
It will be resulted a seizure
if uncorrected.
Always measure the
cylinder bore and the
select piston grade.
