Cylinder Liners: Description

Each cylinder wall liner used on this engine is of the wet design. Coolant is in direct contact with the liner. Three O-rings are used to seal the liner to the engine block. The top O-rings (black) are water seals and the lower (brown) seal is an oil seal. The applicable metal shim is used for cylinder liner protrusion. If the liner is to be reused, match mark the liner and block. Anytime that the liners are removed, replace the O-rings and the shim. If one or more liners have been replaced the liner protrusion must be measured to determine the proper head gasket selection. If the liners are not removed, used the same thickness head gasket that was removed.
