Cylinder Wear
1. Measure the I.D. of the cylinder at the six positions (See
figure) with a cylinder gauge to find the maximum and
minimum J.D:s.
2. Get the difference (Maximum wear) between the maximum
and the minimum I.D.'s
3. If the wear exceeds the allowable limit, bore and hone to the
oversize dimension. (Refer to "Correcting Cylinder")
4. Visually check the cylinder wall for scratches. If deep
scratches are found, the cylinder should be bored. (Refer to
"Correcting Cylinder")
