NOTES
Cylinder liners are available in .001, .005, .010, .020 and .030
inch oversize on the outside diameter. When an oversize liner
is used, the amount of over-size is stamped on top of the
cylinder block adjacent to the liner counter bore.
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.
