- 1. A method of joining a sleeve into a cylinder opening of a reciprocating piston apparatus, comprising:
- forming an internal screw in the cylinder opening along a major portion of the length of the opening;
- forming a cylindrical sleeve having a relatively thick wall;
- forming an external screw thread on the outer diameter of the sleeve along a major portion of its length, said external screw thread being complementary with the internal screw thread of the cylinder opening;
- threading the sleeve into a fixture having a central opening with an internal screw thread the same as that of the cylinder opening;
- machining a cylinder bore in the sleeve while it is held in the fixture to thereby form a thin wall sleeve;
- removing the machined sleeve from the fixture; and
- threading the machined sleeve into the cylinder opening.
- 2. A method in accordance with claim 1 together with the step of tightening the sleeve against an axial abutment to take up the backlash in the complementary screw threads.
- 3. A method in accordance with claim 1 wherein the screw threads are formed along substantially the entire lengths of the sleeve and cylinder opening.
