A couple months ago I asked about installing a power beyond on a 7030 and was told it is possibl e to do it by accessing the passages in the remote valves by drilling holes to them in the rectangular end plate. My question is, which passages are the pressure, return and sensing?

| #4 or #5 are the signal lines to the pump compensator. Choose one of them for signal. #3 is pump output flow which will vary from 400 to 2500 psi and zero to 23 GPM flow depending on the signal. My service book isn't very helpful finding the return to sump passage on the remote valve bodies. You have to use a "closed center" type power beyond valve with a signal line. The return line I don't see how to do that short of just returning thru the lower sight glass hole or tapping into the plate above the drawbar under the PTO gears. I"m not so sure return couldn't go thru #1 or #2 but that valve on the end of the stack would have to be in float, so that wouldn't work very well. |
