Buy a generic pump.

local dealer doesn't have any suggestions on that option

You dont need a dealer to buy a PTO pump. They are readily available online in a wide range of sizes. I suspect you need the smallest you can find.

If you have an existing pump that you need to replace there should be a nameplate on the pump somewhere telling you the flow and pressure at some RPM(s). You can then select a pump that fits onto the PTO shaft that gives you the same performance.

If you are trying to add a pump on the PTO to drive the backhoe and have no idea how the pump needs to perform then you need to get information together on what the backhoe needs to operate satisfactorily and safely. The flow will just be for how fast the backhoe will extend and retract the cylinders. The pressure will determine how much force the backhoe can exert but there may not be much choice on that. I glanced and one site showed three flow rates (maximum) but all developed the same 2250 PSI maximum pressure.

Another suggestion is to ask about it at a local hydraulic design and repair shop that might know a lot about what is needed- assuming you are not that interested in figuring it out yourself.

Good luck.

Thank you

Its not complicated. This pump will give you 7 GPM which is probably a bit more than the OEM pump. Pressure will be determined by the valve on the hoe. Fitting it onto the B7610 PTO will be the main issue.

I don’t see where anyone said it was complicated. I just gave him information on how to select the pump he was looking for.

But thank you for providing that link to what should work.
