Patent ID: 8607560

Claim:
A method for assembling a reciprocating body within a chamber, where the body couples through a rotational coupling to a substantially laterally fixed structure to the chamber, the reciprocating body including a first gas inlet, a gas bearing cavity and one or more gas bearing ports disposed toward the chamber, the first gas inlet, gas bearing cavity and gas bearing ports being in fluidic communication, comprising the steps of: providing a reciprocating body within the chamber, flowing gas through the first gas inlet to the gas bearing cavity and through the gas bearing ports toward sidewalls of the chamber (1) while the body is not coupled to a substantially laterally fixed structure (2) at a pressure at least sufficient to cause the reciprocating body to position into a non-contact relationship with the sidewalls of the chamber within the chamber, affixing the rotational coupling to the substantially laterally fixed structure, said affixing comprising: temporarily attaching the rotational coupling to the structure, and permanently attaching the rotational coupling to the structure, and discontinuing the gas flow.
