IH504 Posted August 3, 2018 Share Posted August 3, 2018 I have nearly got my loader on my IH 504 but am lacking just the fitting to hook my supply line to the control valve stand. These pictures show the valve mounted on my IH 2001 loader and the second shows the hole in which I need to connect. Next to it is a 1 inch nipple and reducer to a 1/2 inch hose, but the open port is smaller than 1 inch but bigger than 3/4. What am I looking for? These holes are NPS thread.

IH504 Posted August 15, 2018 Author Share Posted August 15, 2018 After many tries, I finally found a match, it is a 14 with o ring, that usually is used on Fords. Now I just have to get all the leaks tightened up. Quote Link to comment Share on other sites More sharing options...
