We are thinking about putting GPS machine control on an old (1972-73) 15C for a show and tell project. Would anyone have the flow rate specs on the pump? We think it is likely open center but if anyone knows for sure that would help. Mark
15c pump 52.6 gpm @ 1850 psi. control valve is open center
Thanks for the info. Looks like we will need a big valve. Ran it this afternoon for the first time with new rails and front idlers. Doing a pretty good job for 40 years old. Mark
