Does anyone have any experience with IH hydraulic steering on late 70’s models or any other unit, for that matter?
Our late 70’s IH2500B has hydraulic steering: a ram with two hoses. The rod runs all the way through the cylinder’s case. One end of the rod has a mount that attaches to the frame and a fitting on the mount to feed fluid down the center of the rod. The other end of the rod just has a fitting for the other hydraulic hose. The center of the case is attached to the steering mechanism. So, there are no hydraulic fittings on the cylinder’s case, it is fed through both ends of the rods. Never seen one like this before. Anyway, here’s the problem…
I can hardly turn the steering wheel with the tractor running. Just a little bit in each direction. Even if I lift the front wheels off the ground with the FEL, I cannot turn the wheel. So, I removed the ram and dropped the hoses in a bucket. With the tractor running, I can then turn the steering wheel easily with one finger. As I turn the wheel, hydraulic fluid comes out of one hose. When I turn it the other way, fluid comes out of the other hose. This is expected. However, I was expecting the fluid to come out at great pressure. It does not. It comes out in good volume, but should it be under great pressure? Or, since the cylinder is removed, there is nothing to push against, so there will be no pressure at that point?
I’m going to have the cylinder tested at a local shop, just to make sure it is O.K. before I start tearing out the steering valve but wondered if anyone had any suggestions or similar problems. Thanks in advance.
