I just finished up rebuilding the tandem pumps on my Case 1840. I also rebuilt the drive motors and replace 19 hoses on the machine. I drained all fluids and replaced all filters. Now that it is all reassembled, I am having issues with the tandem pump. I never get fluid to flow to\from the drive motors. I have fluid at some various points of the pump, like the servo piston covers, but never to the motors. I am confused and frustrated at this point and have no idea where to go next. The Case service manual says to put a gauge on a non-existant port on the pump to check charge pressure, so I am not sure where I need to connect to check my pressures. Any help would be greatly appreciated.
