and as the high pressure begins to drop, should we not see a corresponding
increase in pressure on the low side?

Angier,
Take a look at figure 9 in the link.  
If you go to the cylinder you'll be able to follow the low side of the piston all the way back to the reservoir. You might see ~100 psi from the reservoir back pressure spring but that is it.  Pressure does not build beyond that.


As for the sealing washer, "reassembly" on page 8 has some good pics.

Only once have I had a sudden large leak. It was the sealing washer that split under the nut.

Hi Chris,


You said.."It looks like it is time to start isolating circuits and then actuators.  Agreed


I’m not sure what you mean by this.

If it is a cylinder, don't forget about the sealing washer under the piston nut.”

OK, hear’s a dumb question for you….

I have no external leaks so, if there is an internal leak in one of the actuators(I mean cylinders for gear and doors, , and as the high pressure begins to drop, should we not see a corresponding
increase in pressure on the low side?

As for the dump valve, I trashed that which came with the kit in favor of higher quality. I don’t think I have a dump valve issue.

Hoping this does not screw up my plans for KRDM.
