I have a 1960 JD 730 D with power steering that is giving me some problems. The assist part is working fine, it turns real easy and smooth. The problem is when you let go of the wheel it automatically turns right. Is there an adjustment valve somewhere that I'm missing? Any help would be appreciated. Thank you.

There is a valve up front on the right side up at the top of the steering pedistal that you have to loosen and move back and forth to set this. Also need to have the front of the tractor off the ground, and set it at WOT (so block the tactor up good in the back to keep it from rolling). I really can't describe the location, just know where it is. If you can't get a description or figure out where it is let me know and I'll fax/snail mail you the JD diagram. Got a 730 gas that I'm fixin to go thru the power steerin on, did my 60 a few years back and they are basically the same. Hope this helps. HB

Would this procedure apply to an 820 "Haybaler". I have the same problem with my 820. I don't know if power steering systems on an 730 and a 820 because I have never seen or worked on 730

Sorry Green never have seen an 820 PS either. Supposed to be gettin the parts CD in, ifn I forget remind me and I'll look it up and see if the parts look the same on the 730/820. I'm almost bettin that it is similiar. A JD mechanic told me to have the front off the ground when settin this valve, it is the only way to set it properly.

I am having my first go at this on my 820 with the assistance of a professional J D mechanic that has been at it since the Korean War. According to him, the construction is the same, probably some different parts. The part the needs ajusting is the steering valve (adjacent to the worm) which on the 820 has two steel hydralic lines going to the vane housing below. We inverted the pins on the actuating sleeve (must be free of end play) to eliminate a worn surface. When reassembling you need to get the threads on steering shaft worm started before they are started on the worm themselves. Adjusting the steering valve housing was no problem although we did not jack the tractor up. I drove out of the shop and the front wheels were sitting on ice. The objective is to have it adjusted so it does not turn harder in one direction than the other. I tapped the housing with a hammer and held a finger on the junction to determine when it moved. I have the parts book and service manual for the 820, but it is not very detailed. Will answer further questions.

Thanks for the help. I have been driving the 820 like that for 2 years now and it is starting to be of annoyance.
