Farmall c Hydraulics

[Five points John]

I got a C farmall last weekend. I changed the hydraulic oil and pulled the screen out and cleaned it now it won't move the cultivator bracket. it was working ok before but was jerky and wouldn't lift if I was standing on them (175 lbs) I don't have gauges Any help would be appreciated. THANKS in advance John

pump may be air locked or warnout make sure oil is geting to pump

Put pressure in the reservoir (no more than 20psi) and have the front lower than the rear by a foot or more. Then cycle the levers to clear the air. It will not fix a worn pump, but it should prime it. The pressure relief valve may be partially stuck open, or faulty, but worn pump might be it. Jim

OK where is the best place to see if the pump is getting oil?

OK I pulled out that set screw ? facing the right side with the spring behind it. Seems that there was a little air ( it took a second to start running oil out), Oil to there. But still no moveing. John

Had that problem on my Super C, with the engine off remove the little plug on top of pump, squirt some oil in it and move the hyd lever back and forth slowly. Don't let the spring fly out of the hole. Repeat until the air is out and full of oil.

You need to work with the fill hole open, or pressurize the reservoir.

With the fill hole closed it's "air locked" and won't circulate if there is air in the lines.
