1530 power steering -again

[tonyopitz]

Thanks Jim, it looks as if someone has jury rigged this valve assembly . there are washers that have been ground down to fit into the sleeve on top of the spring on the top of the assembly and held on with a snap ring and more modified washers on top of that that jam against the adjuster, doesn't look like the diagram. Which valve would regulate the left turn? There are 3 shims on each valve between the valve and the two spacers in the middle. Do you think I should try to locate another steering valve?

Thanks again Tony

Without a JD tech manual to study I can't determine which valve is for left turn. I think your valves can be shimmed to operate correctly.

Thanks Jim. I will do some digging and see what info I can come up with, I priced a used one (670) rebuilt(840) both want mine as core or $200 , that will be a last resort . I will keep you posted.

Thanks again Tony

I think I got it . I found an article online that gave a procedure for shimming the valves. This guy said to hold the valve assembly in a vise with the 2 valves held together, insert cotter keys in the holes where the little spring loaded valves are, which will hold the valves on their seats and then measure the end play of the shaft. I found 2 different articles 2 different guys, one said the end play should be between .020 and .030 , the other guy said 1/16 . I measured mine with a dial indicator and came up with around .050. it's hard to hold the carter keys in and move the shaft back and forth by yourself. I ordered shims and a washer and retainer that it was missing.( had been jery rigged with an assortment of washers. I added .010 to each valve, which brought to about.030 end play. I also had to unfreeze the jam nut on the adjuster it was pretty rusty and I don't know if the adjuster was all the way down before, because it went down past where it was before . There was a little noise and slight jerking when I first stated it and turned the wheel with the wheels raised , it cleared up it a minute. the is a lot less play in the steering wheel, maybe about a quarter turn .I mowed with it for about an hour and it seemed to steer ok. I don't know if I need to add more shims or just leave it alone. Next on the agenda is draining the 303 fluid that I put in it last year and change the filter and clean the screen again and try to get the pressure relief valve out.

Thanks for all your help and patience.

I think I got it. I found an article online that offered a procedure for shimming the valves,I think it was FIXYA. The guy said to put the valve assembly in a vise so that the two valves are held together, insert cotter keys in the holes where the little spring loaded valves slide so that you hold the valves on their seats and measure the end play of the shaft, He said the end play should be .020 to .030. A little tricky holding the cotter keys in and moving the shaft back and forth but I was able to get a measurement with a dial indicator of about .050. I ordered the shims and a thrust washer and a retainer that were missing and new snap rings. I added .010 to each valve and unfroze the jam nut on the adjuster , I don't think the adjuster was all the way down before. It made a little noise and was a little jerky when I started it up with the wheels off the ground, but cleared up in a minute. there seems to be a lot less play in the steering wheel, maybe 1/4 turn or less. I mowed with it for anout30 minutes .it seemed to steer ok. I don't know if I should add more shims or just leave it alone. next on the agenda is replacing the 303 fluid I put in last year with j20c and cleaning the screen and replacing the filter and try to get the pressure relief valve out.

Thanks again for all your help and patience.

Thanks for the update. I think the shimming you performed will be the solution. I'm not very good at surfing the web. Can you post where you found your shimming deminsions? Thanks,Jim

Coming in late, upper valve is left, lower valve is right

 

[tonyopitz]

the site where I got the procedure is called" just answer heavy equipment". It's one of those sites where you talk to an expert and then you pay him, only I did not talk to him or pay him because you can find alot of stuff that they have been talking about that may be what your problem is. All you have to do is google " just answer heavy equipment 1530 steering" and it will pull up a couple of articles on that subject. Where I got the measurement of .020 -.030 was an article that the same guy did on a 310b backhoe . which seems to have the same steering , that one would be " just answer 310 backhoe steering just turns right" -- I think, anyhow sometimes find these things and have no idea how I got there. But the 310b article is quite long and can be frustrating reading because you are also reading the customers response which can be --frustrating but it does have some pictures . I hope you are able to pull this up, and thanks for the reply Jim, and also ZEBRAFIVE . I am probably going to leave it as it is for now but this winter while I got down time I may do some more experimenting with shimming the valve again to may get it tighter. I was at an equipment lot while I was looking for used valves and the guy had a really solid 2030 he was trying to sell me and the steering on that one was really nice and tight although it did have a slight noise in between right and left , but it was just for and instant.

Again. thanks for all your help

Probably NOT the same; early 2030 (no spring) tech manual said to shim to get a PRE LOAD of .001-.003

 

[tonyopitz]

Interesting, the pictures I saw of the 310b valves did not show a spring either. Should there be clearance between the washer on top of the spring and the adjuster ?, because there is on mine, I didn't measure it but it looks like about 1/8 or so. I'm not exactly sure what the spring does, other than keep some tension on the shaft.

Thanks for the info.
