I am working on a 400 for a friend that was not running, right after I got it running the 3 point would raise and lower (I never tried to move forward or reverse) and now it will not do anything. No hydraulic pressure at all. I ended up pulling the hydro filter off because it was damage, and before I put the new one on I started it briefly to see if it would pump oil out the filter base and it did not. Is the pump not working at all? Is there a lever or something that got moved that need to be engaged? Any help would be great!!

Thank you,

Dustin

Get a 1000 psi gage and plug it into one of the disconnects in the front. If you have zero pressure, then the charge pump is not pumping. The charge pump could have a sheared pin.
