#1 Rod only feeds from #1Main, #2&5 Rods feed from #2Main @ 90°/270° , #3&6 Rods feed from #3Main @ 180° , #4&7 Rods Feed from #4Main @ 90°/270° , #8 Rod only feeds from #5Main.
Amount & duration of feed changes with options of: top main inserts only with groove, full grooved mains , cross drilling etc.
So assuming our man has cyl # correct his problem bearing is being fed from center main.
