Allis Chalmers 5020 hydraulic pump

   Thanks for adding me to the forum. 

 I have an AC 5020 w/ a front end loader.  The poor thing has taken a beating its entire life.  It's been flooded, 6 feet under water three times.  I owned it during the last flood.  There was so much destruction, the tractor sat for months before I could get to it.  I hired a mechanic who turned out not to be a mechanic.  He said he drained the fluids but obviously he didnt.  

The front end loader worked as usual.  Last weekend it stopped going up and down.  It was also making a whining noise when the lever was pulled.  This weekend I found the water in the fluid and the pump isnt even whining any longer.  It does nothing when the levers are avtivated.

Please post your thoughts.  If you have a 5020 please post a pic of the pump.  

Do you have to air bleed these systems?

Any information is appreciated.

I am building a house on Matagorda island and this tractor is an essential part of the build.  The whole reason it is out there is so I can unload pallets of materials off of a barge.  My build is shut down until this thing is fixed.
