Has anyone on here heard of bleeding air out of the hydraulic pump. I have just rebuilt my pump and cylinder including a new piston and rings. before I started the hydraulics worked but were making noise and would not hold up an implement with pto off. now after rebuild hydraulics dont work at all or come up so slow it takes 10 minutes for them to rise up completly. I have pulle it apart 4 times now and cannot find a problem with it. Relief valve and control valve are working. Linkage is all working. no leaks from cylinder when running looking through inspection plate. I am at a loss and frustrated. I cannot figure this out. any help is appreciated.
