Looking at an 850B loader....

Looking at picking up a Case 850b track loader here locally. I've looked at the machine once already, and it looks good to me, FWIW. Having a diesel mechanic take a look at tomorrow. The loader arms have quite a bit of slop in them, several inches of side to side play. Everything else seems to be good, perfect UC, and purs like a kitten. Where should I be focusing my attention?

Thanks ahead of time.
