'53 Super c Hydraulics problem

[Thomas Cooke]

My Three point lift has stopped working all of a sudden like and i can't figure out what it could be. I Have a Paulson loader on front and it works fine, but the Cultivator lifts and the rear lift ram stopped completely. It has plenty of oil in it and before it stopped it was making a screeching noise in the touch control unit but just before it stopped working the noise stopped. I Checked the control valve next to the starter and pulled it off and apart and cleaned a small amount of sediment out of the bottom and reworked two supply/return lines to the joystick next to the steering wheel. I Filled everything up, started the tractor and cracked the lines loose at the joystick(highest point) and bled some air out and refilled it, then repeated it again twice more to top everything off and still nothing. So the only thing i can think of may be the touch control might have a valve sticking and need some ideas. I Need to finish planting my garden but need the tiller on the 3 point to build my rows so the hydraulics need to be running to lift the tiller up and down etc,. Thanks in advance.

Put a good pressure guage in the system and see what kind of pressure your pump is putting out!May be your pump just gave out!

It can't be the pump because the loader still works fine. It runs off the same valve block next to the starter and the
same pump. If it stops raining a little today i'll try to crack loose the supply/return line to the top of the lift ram to
see if there is air trapped in there.

Clean the orifice and orifice screen. You access them by removing the pipe plug in the TC head then unscrewing the orifice. You will need to pull the battery to get at it.

I Removed the big screen in the touch control and it had a rip in the screen so i cleaned it real good and found some
brass screen with the same size openings in the mesh and flux soldered a patch and reinstalled the screen. so i'm thinking
because of the hole in the filter my system must have a blockage somewhere. Any ideas where to start? I Was thinking the
check valve in front of the seat has a few tight places for fluid to pass thru and might be a good place to start.
