Abstract
A rotary machine, such as a compressor, includes a casing having an annular cavity. The cavity is stepped to include a first circumferential surface of a first size and a second circumferential surface of a second size, less than the first size. At least one roller member is retractably mounted in the casing and is adjustable between a first position and a second position. In the first position, the roller member is retracted from the cavity and is substantially aligned with first circumferential surface. In the second position, the roller is extended into the cavity and substantially aligned with the second circumferential surface. When extended, the roller member can support a reduced diameter portion of a compressor bundle substantially in alignment with the second circumferential surface of the cavity during insertion of the compressor bundle into, or removal of the compressor bundle from the cavity in the compressor casing.
