The machine is a 1981 has been setting around for past 3 years. After we started it back up we had to put in roughly 50 gallons of hydraulic oil. Now the problem is the bucket cylinder, turn table, and the right track is very slow and has very little power. When it was parked the machine work very well for its age. Could one of the pumps gone bad and are they rebuildable? thanks. If by chance someone can help you can call me too. 1 319 231 5492. thanks again.
It sounds as if one of the pumps is not increasing displacement and pushing more fluid through. Could be a problem with water in the oil that froze and damaged pieces? Can you take pictures of the pump set up and the tag on them.
Ok when I get back I will take a pic of the set-up. I also forgot to mention when we started it up the one pump started making some noise shortly after starting it and started smoking. After shutting it off and adding more oil the noise went away but it low on hydraulics on those three things i had mentioned. thanks.
