Checking Wear of Cylinder Liner

1) Adjust a cylinder gauge to a reference value of cylinder
liner with an outside micrometer.
2) To find out the maximum wear, measure six points
cylinder diameters with the cylinder
below.
• When the cylinder liner has worm beyond the allowable
limit, bore and hone the cylinder by 0.5 mm (0.0197 in.)
1) Finish the cylinder liner to the degree in Table 1.
2) The cylinder liner which has been oversized by 0.5 mm
(0.0197 in.) should use a piston and ring of the
oversize. (See the Table 2)
• When the oversized cylinder liner is worn beyond the
allowable limit, replace the cylinder liner, and bore and
hone it.
