After cleaning the sump screen, new filters and hydraulic oil. Luck would have it blew a hose on the draft and got to buy some more fluid.
I tested two of the remotes and all held constant pressure with 50-100 psi loss over several minutes. However, i only saw 1800 psi.max. does this mean the pump needs rebuilt? What are the risks running it as is?
