George's post below got me to the thinking of something to ask the brain trust.
I took a load of beans to town yesterday in the old 58 GMC grain truck. I was dreading it because that lift is slow anyway and gets really bad when it is cold. I think it was probably sized for one cylinder and it is a dual cylinder lift. It is the original to the truck. I've added galons of modern fluid to it over the years but never pulled it apart and cleaned the pickup screen. That is this winter's project.
It is four miles to town. I was tempted to engage the pto and drive to town with it on and see if that thinned the hydraulic a little. I read in the original book for it that it should not be run over 1000 rpm. What does the output on the transmission gear it to? I don't ever wind up the engine when dumping because it doesn't seem to help and I don't know what the rpm would be. The old pump leaks enough as it is - I don't need to make that input seal any worse!
Are all of the old transmissions geared to have the same output on the PTO? Is it 540 like the tractors? Sure doesn't look fast with the truck idling.
