I have no idea what the success rate is for rebuild, or if i can get it all back to spec working on a bench here.
Do not know where a hydraulic pump rebuild shop may be. and it will be down maybe weeks that way.
Seems to me i may be best served just replacing the unit, but cost is always a problem.

Someone just bought a new one for short money on eBay a few weeks back. You must have been sleeping Dog!!!

Not knowing exactly what is wrong and which parts would have to be replaced (which should be established first, if possible), my sense is that professional rebuilding of this pump is probably not going to be cheap... and I don't see many rebuilt pumps around. For such an extremely popular backhoe, this tells me something. If it were me, I'd swallow really hard and buy the new pump.
