I have a 2004 cat 303cr that is new to me and is having issues with the aux circuit. When I put the safety lever down I noticed a function constantly engaged. I narrowed it down to the aux function constantly on. The aux foot pedal doesn’t center itself even when it’s locked and feels very sloppy. It also has no resistance when I press it in either direction. So my question is does anyone have a breakdown of the valve under the pedal or can tell me how it centers itself.
