On hydraulic pumps, can all/most of them be mounted standing on end? --- Was asking cause I need to make a system using a vertical crank shaft engine for the power unit and wanted to run pump either belt or direct connect. --- never seen one this way so ideas???? Also drive end could be either up or down --- would that make a difference or is one way better than the other?
