I noticed while hooking up my 3pt log splitter that the hydraulic fluid that seeped out around the coupler while trying to connect the lines to the auxilary connections was milky looking. Which I assume indicates water contamination? I'm assuming that it was the splitter but I'm not sure. How might it have got water in? Actually how could it have gotten in the splitter lines? What is the best coarse to replace fluid? Obviously drain my gearcase, but how do I flush out the cylinder for the splitter? By the way, is there a trick to connecting the hoses? I always struggle to get them connected.
