Hello everybody! My 1537 uniloader is going to be dropped off tomorrow! This will be my very first piece of heavy equipment, and it of course has its problems. I spend more than what you'd call a "considerable" amount of time on the computer, I was more wanting to purchase a backhoe but this little guy came up locally and I just had to hand over a stack of $100's and buy it. I understand these are old, like 70's old, have some kind of complicated belt drive etc. It does move just fine. The problem with this machine is that the hydraulics do not work. I did not check any hydraulic or ATF as is listed on the machine to see if it actually had fluid in it. The guy I bought it from told me the previous owner said it absolutely needed a new pump or have the pump rebuilt. I didn't buy it thinking it would be easy to fix, but I would start with the obvious first anyway. After we shut the machine down, I could hear gargling in the hydraulic controls. I go to the ends of the internet and back to find as much info about all the things I own, and this fine forum came up with somebody asking about a slightly larger model of this (the 1737), so I figured I would join up and start posting! Any help or info will be so greatly appreciated. Thanks!
