Don't know where you're from, but sunsource in Granite Falls, Mn, is a wealth of info. They are an authoized sunstrand dealer. Don't have a n, if you need it I can get it.
Thanks, I live in eastern washington state. The guys at Blue Mtn Ag. in lewiston, ID. gave me an answer and suggested going to Dayton Fluid Power in Dayton,Wa as they have a test bench. I'll do that later this fall. ART
