A burnishing unit includes a housing having a bore extending therethrough. The bore has a first end portion and a second end portion. A first fluid port and a second fluid port are provided on the housing, each fluid port is in communication with the bore. The first fluid port introduces hydraulic fluid to the bore and the second fluid port allows hydraulic fluid to escape from the bore. A removable sleeve is positioned in one of the first end portion and second end portion of the bore. The sleeve includes a sidewall having an opening in communication with the bore and the first fluid port. A hydraulic fitting positioned in the first fluid port has a proximal end portion adapted to receive a hydraulic conduit and a distal end portion. The distal end portion is adapted to sealingly engage the sidewall of the sleeve around the opening provided therein.
