I have a 674 International that has a hydraulic problem. It has set up for a few years and the 3 pt hitch would not raise. I started by changed fluid and filter. I took mcv off and cleaned it good, took unloading valve off and cleaned it real good. Both of these looked fine. One O ring was bad in the MCV, I replaced it. The 3 pt hitch will raise now. I have lost my brakes though. I guess I need to bleed them off. Not sure of where to do that though. When you raise the 3 pt hitch, it will come up fine, then start slowly leaking down, then you can pull the remote lever up and it will hold fine. Does this mean that I need to take the remote valve apart and clean it? I am not sure what the remote lever positions are? (up is engage?, etc...). I also have fluid coming out around the steering wheel, I'm thinking this is just a bad seal on the pump. I need all the help I can get, thanks in advance.
