I recently acquired this b7100 with the b219 loader. The loader was all in pieces and I found most of the parts except the front brackets going to the frame and the pump. I can make new brackets, but I can't find any info on the pump. Does anyone know the GPM and system pressure? I'm looking to buy a universal pump and make my own brackets. I've already downloaded the only manual I can find for the loader and it's not helping.
