I have a B6200 with a B1630 loader and I'm looking for some info on the controller/spool valve so I can buy a new one. Open or closed end hydraulic system, GPM and PSI. Nobody seems to know these answers and I don't want to just throw any old spool valve on it and risk breaking something. I have a workshop manual but it only goes through the 3point hydraulic system and not the loader hydraulics. Thanks a bunch to anyone with help.
