NOTES
Cylinder liners are available in .001, .005, .010,.020 and .030 inch (.0025, .0127,
.0254, .0508, .0762 cm) oversize on the outside diameter. When an oversize liner is
used, the amount of oversize is stamped on top of the cylinder block adjacent to the
liner counterbore.
New service liners, standard and oversize, have an inside diameter of 4.2495 to
4.2511 inch (10.7937 to 10.7978 cm).
Do not modify the surface finish in a new service liner. Since the liner is properly
finished at the factory, any change will adversely affect the seating of the piston
rings.
