I purchased a new to me 2016 CAT 307E2 (KC900251) it's got good power but the right track seems to be weak, but it's a little interesting in that when I engage the controls it seems to strengthen back up, at least seems like it. Does anyone have a diagram on how the hydralics work on this one? Is there one hydralic pump for the whole system or mulitple ones? Sorry excavator maintenance is new to me and I'm trying to learn how this all works
