Beschreibung
Zusammenfassung:	The piston sleeve has a radial positioning surface adjacent to the top surface and an axial positioning surface separated from radially positioning surface by a coolant contact surface. A piston bore extending the length of the piston sleeve is machined to form a non-cylindrical bore. The sleeve is compressed by applying force to the top surface and to the axial positioning surface. The piston sleeve is also heated to a normal working temperature. The compression force and the force due to thermal expansion deforms the piston sleeve and changes the non-cylindrical bore into a substantially cylindrical bore.
