1. Measure the I.D. of the cylinder at the 6 positions (see figure) with a cylinder gauge.
2. Find the maximum and minimum inner diameters.
3. Find the difference between the maximum and the minimum inner diameters.
4. If the maximum I.D. or the difference is more than the allowable limit, bore and hone it to the oversize dimension. (Refer to “Cylinder Correction (Oversize)”.).
5. Check the cylinder wall for scratches. If you find deep scratches, bore the cylinder. (Refer to “Cylinder Correction (Oversize)”.)
