Very often there\u2019s not enough space to hold the pistons and the retainer plate with your fingertips, and since the pistons tend to fall out of the barrel, the insertion process may become somewhat \u201cawkward\u201d, forcing you to put the unit on its side and insert the rotary group assembly in the horizontal position.<\/p>\n\n\n\n<p>A simple o\u2019ring (adequately large, of course) arranged in a tying loop can be of great help here \u2013 creating an elastic retainer that puts inward pressure on the pistons and does not let them slip out of the cylinder block. The pictures are pretty self explanatory. Just don\u2019t forget to&nbsp;take the o\u2019ring out&nbsp;after the rotary group is in place!<\/p>\n\n\n\n<div class=\"wp-block-masonry-gallery-ctc-gal-block\">\n<div class=\"mas-gal-gallery\"><img decoding=\"async\" title=\"\" src=\"https:\/\/hydroazma.ir\/wp-content\/uploads\/2022\/11\/Rotary-Group.jpg\" width=\"16% \" \/><img decoding=\"async\" title=\"\" src=\"https:\/\/hydroazma.ir\/wp-content\/uploads\/2022\/11\/Rotary-Group1.jpg\" width=\"16% \" \/><img decoding=\"async\" title=\"\" src=\"https:\/\/hydroazma.ir\/wp-content\/uploads\/2022\/11\/Rotary-Group2.jpg\" width=\"16% \" \/><img decoding=\"async\" title=\"\" src=\"https:\/\/hydroazma.ir\/wp-content\/uploads\/2022\/11\/Rotary-Group3.jpg\" width=\"16% \" \/><img decoding=\"async\" title=\"\" src=\"https:\/\/hydroazma.ir\/wp-content\/uploads\/2022\/11\/Rotary-Group4.jpg\" width=\"16% \" \/><img decoding=\"async\" title=\"\" src=\"https:\/\/hydroazma.ir\/wp-content\/uploads\/2022\/11\/Rotary-Group5.jpg\" width=\"16% \" \/><\/div>\n<\/div>\n\n\n\n<p>Source:<a href=\"https:\/\/www.insanehydraulics.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">&nbsp;www.insanehydraulics.com<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>O\u2019ring to Retain a Rotary Group A few sad pictures of an A11VO160 open circuit pump, I believe this one even had old Hydromatik name plate, which is a rare sight these days.
