I have a Cat 930G Loader and am having problems with the hydraulics. The problem started with losing hydraulics to the bucket randomly. When hydraulics were lost if you turned the Loader off and back on it would fix the problem. Eventually this quick fix stopped working and had no hydraulics at all for bucket operation. Replaced the priority valve (recommendation of local CAT dealer) and the bucket worked great for about 5 min and then nothing. During all this time the hydraulics to the steering worked. Have tried everything can think of but cannot figure it out.
