Hi, New to here and case equipment. Found a nice 1838 case skid steer think it is a 1999 with 1156 hrs. Working on changing the fluids now and going over things on it. Anyone know if I should be looking for any certain things that may go wrong on these machines with that kind of hrs. on it? Anyone know where to get the correct service manuals? found a few on ebay but was wondering if there is anything on line to just look at when working on it. Thanks in advance for any help.
