No Pump from Top/Window Pump

[abelincoln]

I'm attempting to restovate a 48 LC hydraulic system so the top and windows can be operated. I disassembled the pump and cleaned 30 yrs of crud from inside and freed up the regulator valve. Got the pump motor to run without too much arching by sanding the brushes. But, can't get any fluid to come out. I tried priming both sides with dexron II, even took out the regulator valve and spring. Still no fluid. Am I missing something? Every time I take the pump apart, I get transmission fluid on the floor.

Thanks

If the pump itself is free then the problem may be the very thin port plate under the pump rotor. It has a very small tab that holds it in place and if this tab is bent or broken the port plate will rotate with the rotor causing the pump to circulate fluid within itself. This is easy to miss if you're not familar with these pumps.
