I have a new-to-me inop (engine doesn't run) 963C. It was lifted onto my trailer by a wheeled loader, and I'm trying now to remove it from the trailer so I can work on it. Per the manual I have removed the valves from the drive motor assemblies on either side, and did the manual override for the traction control. I connected a porta-power to the traction control box under the cab, and pumped it up to at least 350psi.
With one side lifted off the ground I can get the wheels in the air to rotate ~1/4 turn by hand with significant resistance, then the pressure seems to bleed down and I cant move the wheels anymore. I repump up the porta-power and I can get about another 1/4 turn. I would have expected the wheels to turn freely with the porta power engaged, and I don't know that I'm going to be able to pull it off the trailer like this.
Am I doing something wrong? Do I have the wrong expectation and this behavior is normal? Is something failing internally? Pls help
