Compressor including end cap having internal features and methods of assembling the same

A method of assembling a compressor, the method comprising:

• positioning a main bearing housing into engagement with an annular axial ledge of an upper end of a compressor shell;
• positioning a scroll assembly into engagement with a top surface of the main bearing housing, wherein the scroll assembly comprises an orbiting scroll and a non-orbiting scroll;
• engaging at least one of the main bearing housing and the non-orbiting scroll with an internal feature of an end cap;
• compressing at least one of the main bearing housing and the non-orbiting scroll between the internal feature of the end cap and the axial ledge of the compressor shell;
• and
• attaching the end cap to the upper end of the compressor shell while the at least one of the main bearing housing and the non-orbiting scroll is compressed between the internal feature of the end cap and the axial ledge, such that the attachment of the end cap to the compressor shell retains a compressive force against the at least one of the main bearing housing and the non-orbiting scroll.
