Cylinder Liner I.D.
1. Visually check the cylinder liner I.D. for vertical scratches.
2. Measure the six points as shown in the figure with a cylinder
gauge to find out the maximum wear. Generally, position (1) in
the (a) direction (at approx. 10 mm (0.39 in.) from the top) shows
the maximum wear. Since position (3) at the lower part of the
liner shown the minimum wear, find this difference.
3. If the measurement exceeds the allowable limit, replace the
cylinder liner.

engine oil to the wall of cylinder liner bore, and apply grease to
the O-ring.
3. Press-fit the cylinder liner into the cylinder block.
4. After press-fitting the liner, check the projection of cylinder liner.
Projection of Cylinder Liner
1. Apply straight edge to the flange portion of cylinder liner, and
measure the gap "A" between the cylinder block and the
