1900 3 POINT HITCH WON'T RAISE

[JC-jetro]

ok i did pull spool apart, not to worry I teach machining and fabrication and repair all my own equipment,lathes , milling machines , power shears....but this is kicking my butt!!!! ok worry !! it all came apart as it should except the slotted port #21 check valve seat, it is TIGHT!!! , Will make a tool to fit slot better and get it out, everything else is clean and free ,all o rings looked good,

Okay, why don't you take close up pics of the block and ports so will have it for future reference. 3 bolts that attaches the relief to lift cover are long due to hyd block width. As Jim suggested if you temporarily take out the block then you can check your spool and lift system now that we know you have flow up to that point. I wonder if you have shorter bolts or can put enough shims/washers to make it work.

woo hoo, :thumbsup:slowly but surely.. we reached the top. That shows your lift spool works, shock relief works like it should and piston seal is working at least as of now. Got to check that check valve on the hyd block. The guilty part is found.

That's a great price and good tractor you got. These series Ford Tractors are real work horses, give them a bit TLC and they repay it all.

Wow! I went away long enough to watch my Rangers choke in the World Series and this morning I see you've fixed your tractor. YEA!!!! Way to go, Toolhawk!:thumbsup: My guess is that one of the internal o-ring seals was leaking and you replaced the seal or somehow stopped the leak. It's all good.
