Hydraulic problem of 3 point hitch on FORD 1720

I had previously had my 1720 in my shop forva good going over and lots of sheetmetal work and painting. It ran perfect when it went in, but when I tool it back out I no longer have a working 3 point hitch. Only thing related to hydraulics that I touched was changing the hyd. Filter, and unscrewing the flow control valve that adjusts the speed the 3 points comes down. I checked the diverter valve and it was in correct position. Used a hyd test gauge and its shows no pressure when checking 3 point hydraulics, but has pressure when diverter is put in FEL position, so I believe my pump is good. This tractor hydraulics as no remote hydraulics or FEL. I am thinking I nay have dropped a check bal or something that I never saw, and reassembled the adjuster without it, but am not sure. The part I removed was simply a gland nut with a valve stem. Similar to a faucet stem. I suspect the hydraulic fluid is simply free flowing thru the flow controller thru a missing check ball or such. Any clues what my problem might be? My 0ressure at the diverter us at the liw end but still within the acceptable range limits.

Are the 3pt arms up or down?

post #6 in this thread may be of some help.


I have an older 2110, not sure if it will apply to yours but in addition to the filter, there is a screen in the transmission where the pipe goes from the transmission to the filter up front, on mine it kept getting restricted, ended up cutting it out.

Don't know a fix, but I grew up on older Ford tractors and it wasn't uncommon for them to develop 3PH issues. The one I always would see is that they would stop going up very high. They would raise up some, but not to the height that they were supposed to lift to. So you'd be riding around with a bush hog or disk riding only a few inches above the ground, and if you hit some bumps, or went over some uneven ground like what is common on a tractor during transport that's not being driven on a paved road then you would start getting ground strikes with the implement.

I was always told that it was just an issue that older Fords would often develop. I'm sure there's a fix, but IDK what it is.
