Dan you are on. Give me a bit as I forgot the oring for the relief valve. Same price I just want you guys to have everything.

No rush Don.  Just want a kit on hand for backup.  Nothing leaking at the moment.

Got the o-rings from Ducky! Thanks! Put the valve back together. Not enough time to install it as I have all the fittings to change out to JIC on the hoses and I just didn't feel like playing in hydraulic oil today! Anyways, I'm home alone tonight and have to figure out supper!

IF things go well today, I plan to run a test bypassing the valve while I have things apart. Then install this valve and see what happens. Still plan to pull the 3-point and move the cylinder mount further away from the pivot (rockshaft) there. Can't go too much or lift height will suffer badly!

Got the old valve off. Plumbed it's return straight to the gauge.

This is what I got when I first fired it off, idling about 1200 RPM.

After it warmed up some, this is a slow idle.

And this is wide open.

So the valve is not causing this pressure. Must be the filter. Unless someone has a better idea!

The 2-spool valve is on! No leaks that I have found as yet. And best of all, no more squealing! Here's a video!

 

 

Now to see how the fork lift does!

Not totally solved as yet! I can lift a 12" 3-point plow with no problem. But the fork lift with an empty 55 gallon drum is a no-go! Gonna have to rework the 3-point pivot. This may take some major cosmetic surgery!

Great to hear you got most of your problems worked out . Did you ever find out why the valve wasn't working before you rebuilt it ?

I got the 3-point off today. Threw some #'s in the drawing program. Think I found the issue with it not lifting much. My link arms are 6.5" long from center of the pivot shaft. My cylinder hooks in at 3.1875", less than half. The cylinder only has a 3" stroke. If I had a 4" stroke cylinder, it would be 3.5" out from center, more than half the lift link arm. Thus giving much more leverage. Not sure what to do here! I can move the cylinder mount point further out with no issue other than that drops the amount of lift, which could be an issue with a plow on there!

 

Wish I had known this cylinder was only a 3" stroke before I sold the 4" one.

Here is a cylinder I used on a home built 3 point for a big wheel Case. It worked out great and would probably be what your looking for.
