I found the problem with the vane pump. The center section was flipped for CCW rotation. I flipped it so the arrow on the center section is facing the same way as rotation of shaft. I made a video explaining it better, hope it helps others.

I figured out the problem with my vane pump. It was set up for CCW rotation. I flipped the center section of the vane pump around and now I am getting pressure out of the output instead of vacuum. I am posting a video so others can learn from my experience.

I have a bobcat 743 I am trying to run on a 22hp Predator motor. I can't figure out the pump. The machine was complete, but not working when I got it. The motor was shot and I was assured the tandem pump was absolutely working fine which is why I bought it. Obviously I was lied to so I ended up...

Current Status: Pump was disassembled and both wear surfaces on the rotating assemblies were sanded smooth on a flat plate with 600 grit sand paper until all grooves were gone. Pump reinstalled and new oil added. Left drive motor works now, but right drive does not. Before tear down the...

I think it's 22hp. I don't expect it to be super strong, but it should lift moderate loads and drive fine once it is working right.

I have the entire setup apart now while I rebuild the Hydro Pump. This is the hose routing on the machine that matches the manual hose diagram. I also drew (badly) a diagram and took plenty of pictures. I hope this helps someone else in the future.

Before I tackle the Hydro Pump does anyone have any advice for marking parts or making sure I don't lose something? I cracked all of the hydraulic lines loose and no pressure was relieved so there must be something stopping the pump from turning. My guess is the last person to work on it knew...

I am going to drain everything. I am also taking the pump out and tearing into it so there won't be anywhere for water to hide, lol.
