ABSTRACT:
A cast iron sleeve liner for an internal combustion engine cylinder, or other reciprocating piston apparatus, is provided with external screw threads on its outer diameter along substantially its entire length. The screw threads engage complementary internal screw threads that are formed in a cylinder opening. One end of the sleeve abuts against a shoulder in the cylinder as the sleeve is threaded into the cylinder to force the cooperating threads into contact to take up the backlash, or clearance, between the threads. The clearance between the threads may be filled with a sealant. The sleeve can be produced wholly apart from the cylinder by first forming a raw cylindrical casting, then forming the exterior screw threads, and then machining the cylinder bore in the sleeve while the sleeve is held in a fixture which simulates the cylinder opening.
