I had a similar problem with my 07 Jinma, 254. I have two pumps, one for the power steering and one for the TPH and FEL on my model. After some troubleshooting, I found the pump and cylinder were good. The pump was not turning. Little ridges inside the shaft had worn off and would not turn the pump drive shaft. Ronald at Ranch Hand tried his best to find me a new gear/shaft with no luck and then attempted to get one make for me and again could not find a machine shop that could or would make a new shaft.

I have since found a shop locally that will make me a new shaft with a slight modification. The price is high, but I still feel it is reasonable. I took it into a shop on 9 Jun 11 and they told me it would be ready next Monday, 13 Jun 11.

I hope, you have now gotten yours corrected.
