Hi, I'm trying for the first time to change out my hydraulic fluid filter on my 1974 Case 1737 skid steer. It has a big 1 and 1/4 inch nut on top and has a center 'pipe' that comes out. I cranked on that baby with a pipe wrench and a crow bar and was only able to move it about an inch or so until I ran out of room to adjust the pipe wrench. Now I'm thinking maybe it has reverse threads and I was going in the wrong direction? Has anyone seen reverse threads on this?
