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.
