Abstract : The expander system is utilized for installation and removal of a rubber boot over an underwater transducer. The installation system comprises a vacuum tank, adjusting sleeves, boot spreader and C clamps. The rubber boot is expanded at both ends by means of the boot spreader and then is expanded along its sidewall in a radial direction by means of a differential pressure created by pulling a vacuum on the outside surface of the rubber boot. The boot is then slipped on the transducer. For removal of the boot a short handled hook tool is used in place of the boot spreader. The method again includes pulling a vacuum on the outside surface of the rubber boot so the boot expands enabling the removal of the transducer. (Author)
