I blew out a hydraulic hose on my B7300 when I was in the middle of a big job, so I just took off the loader and got back to work. Figured I'd replace all four hoses (they're over 20 years old) later. Well, the previous owner left a surprise for me. (see photo) I thought I knew which hose went where, but when the hoses have different colored tape on their two ends, well, no, I don't.
I couldn't find anything in my manuals or on the Web about the proper way to connect the loader hoses to the control block. Nobody more knowledgeable being available, I figured trial-and-error can't hurt. That was incorrect. Some of the 24 possibilities can blow out other hoses. So the next time the parts counter was open, I asked for advice. The guy behind the counter magnified the parts manual so a picture a quarter-inch on a side was legible and we figured it out from there. The loader is an LA271.
