Hi Glenn,

The flow rating on the second pump for that tractor should be 8.5 US GPM at 2500 psi. I don't know the part # off hand, but I'll assume you got the right one. Now, this part is getting tricky. I assumed you had the delux closed center remote valves. If you did, you shouldn't have to pull any valve to use the loader..... So, do you have any factory remotes, or have you just plumbed an open center valve to the ASC valve port? As far as I know, the 10 series tractors should all have a priority valve pack that allows them to use the closed center remotes....... but I'm not sure on that. The basic idea with the second pump that you listed is to provide additional flow to the remote circuit.... up to 18.2 GPM, while the 3-point maintains priority on the main pump at 9.7 GPM. This system allows you to use the 3-point and remote circuits at the same time. When the 3-point is lifting, it takes the main pump flow, and the remotes get the second pumps flow, and when the 3-point is raised, the flows are again combined, and sent to the remotes, as demanded.
If you don't have any factory valves on the tractor.... and have just plumbed into the ASC valve, and you simply want a separate pump to power the loader, then I would look at a self contained hydraulic system with a front mount pump drive with a stinger shaft off the crank. That way you can size a pump to about 15-20 gpm which is a good size for a decent size loader. Personally, I would look at what parts are needed to install the closed center valves, and also install a closed center loader valve. Dunno what you want..... That could be a fair bit $$$$$$ too. If you could post a picture of the area of that valve you pull (under the seat) it would be a help too. I could see what setup is there, and mabey suggest what other parts you need. HTH.
