Sounds like you shucked a pump. I have two of these machines a B-50 and A b-50-1. These have a tandem piston pump with a gear pump on the back of the tandem. The gear pump supplies the blade and the swing. This pump must still be good. The tamden piston pumps supply everything else. Just went through this last summer. You need to replace the piston pumps. Very expensive $4000.00 plus for the pumps. No one in the U.S. has a replacement or a rebuild for this pump. Get ahold of Dominion Equipment @ 1-800-365-7260 or 804-752-7539 and talk to Buck. He can help you out and can tell you for sure if this is the problem. Great little machines if you don't run them out of oil. That is what happened with mine, an employee ran it after an oil line to the tracks broke. He tried to get it loaded on the trailer and even added more hyd. fluid, but by then it was too late. Probably why it was at auction, just a guess tho. Good luck. Email me if you have any questions.
