Yea I did a utube video on this also. I think the biggest issue on these is trapped air.
Once it is compressed in the cylinder it acts like a spring and any air in the line or a leaking valve will allow that air to force fluid out fast enough to lock the ball.
I think the key to releasing these is to either:
A. Remove the fitting, screen and spring, then push the ball off the seat with a thin probe to release the stored pressure.
B. Pump in the opposite direction. This pressure should force the ball off of the seat. Then you must very very slowly release the pressure, so the trapped air pressure in the cylinder will force the fluid past the check-ball slow enough not to trip it.
I think the rotary control valve may have a dead/open spot in it so when you grab and twist to rotate it normally to the opposite position, it allows a brief period of high flow which re-locks that check-ball. I dont know if it can be rotated slow enough to release the pressure slow enough, maybe… Another way might be, that once pressurized which should release the ball, you slowly crack a fitting and let the fluid slowly drip out until all the pressure has escaped. this should leave the ball in the neutral position and allow the cylinder to move normally…
I'm having this issue again on a A1 truck. Got a link to the video?
Edit: Method "B" for the win. Thanks!
