Abstract

Abstract Apparatus is provided for mounting an object on a carrying rod or for removing an object from a carrying rod such as a guide means conventionally employed on sucker rod strings which are used in pumping an oil well. The apparatus employs a support means which supports the carrying rod with or without a guide means attached, and a separate press means for forcing the guide means onto or off of the carrying rod while the carrying rod is supported by the support means.
