Thanks to All for Help with TNT

One of the spools on the joystick valve has a "float" detent-just like your FEL does...He is asking what cylinder have hooked to that spool-the TOP or the TILT?

The top cylinder does. Y'all can tell how much I know about hydraulics. lol. I know what a two spool valve is and I can recognize hydraulic cylinders almost every time, and that's it.

That is why I hang around here and ask questions.

I just want to clarify something for you and Zephrant that I just thought about:

Even though you have the float spool, your cylinder will not float because of the POCV (Pilot Operated Check Valve) that comes on the CCM cylinders. The cylinder will only move when the POCV see's pressure on the feed lines.

 

[daBear]

Yep, what he said. My words exactly. I was just fixin to say that.

Thanks, that was the information I was looking for. Not sure I'd need the top link to float, but was thinking it might be handy for a mower. But I was also wondering if it wouldn't float too slow (be too restrictive) to be useful that way too.

I have plans to get a flail mower some day, but I think I'd just run it with the 3PH in float-down mode.

I do like that Joystick- I think that plus the solenoid-selector might fulfill all my current desires for hydraulic ports.

Did you use any restrictors to slow down the movement on the tilt?

Ken- Would you recommend the cylinder with the check-valve on a CUT or not? The only time I can see it maybe being useful is if I'm using a splitter or something like it on the 3PH.

No restrictors to slow anything down. Just 1/4" hose from the valve to the cylinders. Works nice and at the correct speed you need.

I would recommend it. It will NOT leak down or change position if you do not want it to. Period. And I think the price of them is only $20 or $30 more than others are selling regular cylinders for.

Do a search for "ccm" and "pocv" for lots of testimonials...

That's the same control valve I ordered a while back and looking to mount it in roughly the same spot on my B7800 ( I have a couple other spot in mind but I'll start there). Thanks for the pic's. I've been going crazy trying to fiqure out plumbing and set-up for months. Now if winter would give me a break so I can get started.

The plumbing is simple after you see it done. I am not even going to say how much the local hydraulic shop charged for it, but I had no choice since I am not knowledgeable of all things hydraulic. If you need any more pictures to be able to do it yourself and avoid shop cost just let me know.

What I especially like is paying what I did for the plumbing and looking at all the fittings chat have "China" stamped in them.

Just a thought (or question) about float. Wouldn't you still get much the same effect from the lift arms floating if 3 pt is set so, even if CCM Hyd 3rd link is rigid since it always is with a non-hyd. top link?

100% correct.
