Maybe everybody else already knows this, but I'm a newbie to hydraulics, so here's my story:
Had a couple of new 38" hoses made up at a JD dealership the other day, and when I got them home, just as a precaution I filled them each about 1/2 full of diesel fuel, sloshed them around a while and drained them into a paper towel, then blew them out good with air. I did this on the advice of an experienced hydraulics shop guy I know. He recommended using diesel fuel for rinsing, and cautioned me never to put alcohol, lacquer thinner, gasoline, or any other volatile liquid in a hydraulic hose--apparently that will dry out the rubber and contribute to future cracks or something. Sounded logical to me. Anyway, I wish I had taken a photo of the black rubber crumbs and crud that came out of one of them, probably more than a teaspoon full. I suppose it was residue from whatever method they used to cut the new hose (a cutoff wheel?). The other hose was clean as a whistle-go figure.
So before you slap on those new hoses you just got, rinse and blow them out good. Otherwise, you might end up with nasty stuff in your cylinders, valves, or filter!
