I'm having a weird problem with my New Holland 1530 compact tractor. The power steering cylinder/ram is bending shafts like crazy. I'm on the 3rd bent shaft. When I'm steering all the way to the left and hit the lock the shaft wants to keep pushing out of the cylinder and ultimately bends the shaft as if it were hollow. I did an inline (in series) power steering pressure test and the pressure is jumping real high when the steering gets to the locks. I saw the gauge staying fairly steady at 1400 psi and below while turning the wheel and then jump upwards of over 4000 psi when it's on the lock. I back off immediately as it scares me to see that much pressure. I'm not sure if it would go any higher.
That seems like excessive pressure to me so I took the relief valve out of the steering motor under the steering column to inspect it. It's a very simple valve and doesn't appear to be sticking. I could be wrong though. I did see some slight wear on it but not much.
I'm assuming that this pressure is way to high, and it is just a simple system that consists of a steering motor (I don't understand this part very much)that connects directly to the steering wheel, a pump, and a steering cylinder/ram.
Any help would be greatly appreciated.
