NW Ohio,near Findlay | Been in the heavy equipment long time. Older excavators, pans, older loaders had lower pressure, very large cylinders. Example where I worked we had a mid to late 60's Warner, Swasey (spelling ?) Hopto 500 series excavator. Was a big machine at the time. Large bore cylinders, had packing glands, with backup orings. About every two years, had to pull them out, rebuild them. If you didn't, the packing would wear enough to where the piston would scuff, groove the cylinder bore. Newer cylinders have wear rings to keep piston from doing that.
Posters on AgTalk before have done the same thing you did, pull some older scraper out of the weeds and hooked it up to a newer tractor, never do that. I'm not concerned about your old junk cylinder, what about all the old, contaminated oil you have returned to your expensive tractor. If you just connected both hoses to your remotes, whatever was in that old cylinder went back to your system.
I would never trust that old stuff on a newer hydraulic system. Pulling a pan, my opinion only, not worth the time. I know AgTalkers do it all the time, but hard on a Farm tractor.
