530 power steering?

[Lazy WP]

I finally got it running good, now it tries to left on its own, and I can hardly turn it to the right, and I am a pretty good size guy. What do I have wrong. This is the one where the valve is on the steering cylinder.
Thanks

Hopefully mEl or Joe (WA) will pop in and elaborate. There are springs on each side of the ball on the mechanical linkage, that engages the socket in the valve. It sounds like one of the springs is broke.
Ps the hyds. you have setting are on hold for me. for a bit, something else came up, requiring my extra money (if there is such a thing). If they don,t chime in, I will try to post some pics of the steering valve, but they won't be like joe's.

You pay the shipping and send me a couple quarts of syrup, and the hydraulic setup is yours. It might even fit in a flat rate box. I'll do some more checking into it.

Ok, here is what I have going on. With the front end off of the ground, and the engine running, I can't turn the wheels to the right. With the engine off, it turn pretty easily.
I tried using a screw driver to pry it back and forth, and either I'm not doing it right, or I have something screwed up. I did a search, and found where this was discussed a couple years ago, but I'm not having much success.

First of all adjust your tie rods to have the wheels straight ahead when the piston is about mid travel in the cylinder. The drag link is not forcing the valve actuator out of neutral. Remove that grease zerk in case the threaded end is too long and try your screwdriver pry again. Pry against the stud ball seat as shown and again on the other side.

If the actuator can only be pried in one steering direction, pin #23 in adjustment nut #24 may be broken and adrift obstructing the spool travel. Broken pin generally happens doing assembly so the question is has this cylinder functioned since the last time it was apart? Pic is a broken pin, small piece is the obstructer. Shank of a 1/8" drill bit makes a suitable pin.

If the actuator can be pried in both directions but the steering force does not change, spool bolt #22 may be broken.

Spool travel is very narrow, less than a 1/4" total so it doesn"t take much to cause problems. Misadjustment (#24), excessive wear, etc are also potentials, you just have to take it apart and check.

Last pic is a 310, your drag link will be different and some other minor changes but operationally the same.

I had never had this apart. Bought the tractor as a "hay sweep" and turned it back around. I am putting my #22 loader and backhoe on it. When I drove it into the shop, I thought that some of the reverse steering were hanging up, but now I am sure its in the actuator.

I think I got it figured out. Removed the grease zerk, and it will at least turn both directions now. Thanks

The original grease zerk was straight and had a short thread. When I see it has been changed as in the 90 deg zerk on yours there is chance that a longer threaded zerk will lock up the actuator slide.
