530 power trol issue

[KJohnson92]

Ok well, anyone who read my post yesterday knew I am trying to get the hydraulics going on my 530. I plan to switch to Hy guard, but the little disc I'm working on already had ND oil in the cyl, so I figured I would test it, as I just put new lines to the cyl. So I noticed a probelem. I hooked the line to lift the disc to my top port, and the line to drop it to the lower port. I notice two issues.

1- the top port does put out pressure, but it seems slow, even for an old girl, and as soon as the implement reaches the stop, it makes a whining/screeching sort of noise.

2- the lower port builds no pressure at all it seems, if I let the disc down, it would drop from gravity, but not lift the wheels up to put the disc into the ground.

Switching lines provided the same results, just opposite of each other of course.

If there is a FAQ on this I'm sorry I didn't find it. I searched and found other issues but not one exactly like mine. The system had ND oil in it which is a bit old, but not dirty after running the system to stir anything in there up, and not low at all.

I want to add that my 3 point functions perfectly.

Did you set the adjustment nut for using the remote? Check this first. I bet its shut off

Xtroop has the answer - on the right hand side of the hydraulic valve body you will see a "tall" closed end nut (can't remember the proper name). It is actually a cap with hex sides. Remove the nut/cap and there will be a threaded valve with a screw slot under it. I "think" you screw the threaded valve down until it hits bottom to have two way pressure. If it is already screwed down, try screwing it out and then re-install the nut/cap. One way is single acting hydraulics and the other way is double acting hydraulics.

Thanks I'll check that out. Dad thought there was something like that when I asked him earlier but he couldn't remember how it was changed. Now that I think about it the only thing we used it on in recent times were lifting the hay elevator and grain auger, both which have a single hose to the cylinder and use their weight to lower when released.

Hadn't touched anything. Still learning the ins and outs of this old girl. Everything we use regularly is newer stuff. 4010 up thru a 7820. Dad told me he thought you had to change the unit to function for a 2 way cyl and that it was set for a 1 way cyl but he didn't remember how as it has been the way it is for 20+ years. I'll definitely look into that. I don't have a manual for her but it looks like I need to invest in one.

 

[r.w.b.]

Yes a long capnut prolly inch n half long.seeme like 2 way is screwed out cant remember but dont tighten it much just snug and draw the cap nut up snug maybe 5 ft pounds. Should be a copper sealing washer under that cap nut too

Thanks, I found it! Works as it should now Got the disc functioning and did the terrace side of the inlet pipes in the hayfields so it's easier to see them. Now I can't wait for second cutting so I can use the speedrake behind her too!
