I have a Ford one arm loader that came mounted to my Ford 850 tractor. I removed it 16 years ago but now want to reinstall it. The ID tag is missing but I believe it to be a 722 because it is hydraulic dump. I bought a owner's manual for the 722 and it has instructions for installing on 601, 801, 2000 & 4000. My loader does not have a pump or spool valves, rather it uses the hydraulics from the tractor. My tractor has spool valves on the lift cover. Following install directions, in the manual, all is okay until I get to putting on the "Trunnion Rod" and "Loader-to-Rear Axle Brace". My loader does not have the WEBs that these items attach. I see the WEBs in the pictures in my manual and in pictures of other one arm loaders but they are not on mine and do not appear they ever have been. Is my loader a 722? Is the Trunnion Rod and Brace required as the manual states?
