Hello everyone, I am new to excavators and just picked up an old sumitomo (IHI) uj18 mini excavator. As the title suggests this machine has widening tracks. they were working for a little while, then i sucked them in, and one of the tracks got stuck in the narrow position. I am really just wondering how this system works. from what I know, it is a single hydraulic cylinder that operates boths sides. and the tracks are on a sort of "rail" system (small tube inside of big tube). I have cleaned it as best i can with no luck. So as it sits now, one track is free moving and the other is stuck all the way in. I have tried to pull it with my tractor while operating the hydraulics with no luck. Should I just pull it harder??
thanks everyone.
thanks everyone.
