I recently picked up a bobcat 2000 wheel loader. The hystats are extremely jumpy to the point is dangerous to operate. I've taken out a lot of slop in the linkage but i'm looking for info on how the servo is supposed to control things. Is the arm on the front pump for travel and the arm on the rear for something else? I have ordered the book but i was hoping someone might have the theory of operations handy i could look at till it arrives.
Check the charge pressure.... inlet hose between the tank/ charge pump inlet..... possible strainer or filter before the fluid hits the loop
