grapple mounted...next hydraulics

[stormpetrel]

The new grapple arrived today. Man, is this thing built well!! Four holes (and plenty of oil) later, and it's on. Have to figure out valve type, hose length, and a few other things to get the hydraulics set. I now have a decent understanding of how hydraulics work; shouldn't be too hard

Still not totally sure which ports from loader valve to use......but in should be on one side and out on the other.....?

Also, not sure if I have the cylinder pointed in the right direction. Does this matter?

Any suggestions or advice will be much appreciated.

Nice looking grapple:thumbsup: You might want to turn the cylinder around so the hoses don't have to move in and out with the ram.

I'm wondering if you wouldn't need a new valve for your grapple? Would seem to me using a grapple on your loader you would need both the lift and curl function. If you did without either it would have to be the curl cylinders. After reading your post again sounds like you are planning for a new valve. I'm slow to understand sometimes.

Yep, need a valve. I just got off the phone w/surplus center. Ordered all the fittings, hoses, adapters, and the valve.

A very interesting thing happened when I talked to the Koyker people about the power beyond sleeve. The guy I talked to told me NOT to "Tee" the return line, no way, no how. He said to take the return line off the loader valve, and attach it to the return port of the new grapple valve, and then to run a new return line from the loader valve. Does that mean I'll have two return lines going to the pto...?

The two diagrams I've seen both show the return lines Teed together.......:confused2:


Every time I think I have this down, something new pops up and confuses the **** out of me!!!!!!!

Any opinions/advice?

How may threads about this?:confused2:

I hope the SC guy was not understanding what you where saying-cause that sure is bad advice he gave!

 

[kennyd]

Kennyd... I think it's "keeping up with the Jones"... one guy does it we all have to do it. Also, "SC guy" didn't give advice... it was "Koyker people" the loader people...

"...I talked to the Koyker people about the power beyond sleeve. The guy I talked to told me NOT to "Tee" the return line, no way, no how. {I wonder if he is talking about the HIGH Pressure line, which is correct} He said to take the return line off the loader valve, and attach it to the return port of the new grapple valve, and then to run a new return line {I'm thinking he means the Low pressure return to the tank} from the loader valve. Does that mean I'll have two return lines going to the pto...? {one is high pressure - power beyond for the 3ph. The other low pressure to return to the tank. If you make a mistake, Like I ALMOST did... it's going to be ugly}

Good luck...

Thanks Teg...My bad, missed the Koyker people sentence

I have a Green's machine thumb,works great...don't know about your hydraulic connections;but turn the cylinder around and put ninety degree elbows in the cylinder;keeps the hoses back a little.

 

[nybirdman]

Forgot,tooth-bar will make the thumb work a lot better...brush ,logs ect.

 

[stormpetrel]

The man at Koyker told me that if I "teed" the return line I would lose the 3ph/pto. What the heck do I do then?

The diagram I saw from Prince valves showed the two valve's return lines teed together...if that's NOT the case, what is?

Thanks Birdman...I ordered the 90s, thinking exactly that!!

This instruction sheet may be like your installation. http://www.princehyd.com/Portals/0/products/valves/RD5000InstS.pdf

That's the very diagram I was modeling my install on: until told not to. I'm no longer sure what to do. That "no tee" advice has me all confused. The guy knew I was talking about the return, and not the high pressure line from the pump.

He told me I would lose power to the 3ph/pto when using the grapple if I did that. Is that so, or not?

 

[stormpetrel]

That's a good diagram BUT the second Valve does not have power beyond which gives power to the 3 point hitch. If that diagram had a high pressure line coming out of the 2nd valve (like the first valve), With the power beyond hose tying into the block (for the 3ph) it would be perfect... Also, I've added to my response above...

Teg,
Do you have a diagram showing that setup? I understand what you're saying, but cannot picture it clearly in my (very tired and confused) mind.

 

[stormpetrel]

Try this... read the paragraph in the upper left...

PS. You've seen my thread, right? http://www.tractorbynet.com/forums/...7948-instructions-add-extra-spools-l2800.html

I've seen it. My loader valve has only two hoses; one high pressure from the hydraulic pump, and one that goes back to the pto. There is no third hose. Ergo,:confused2:

 

[stormpetrel]

Have you told us what Spool the Surplus Center guy sold you???

9-6701 single spool open center by Prince
So I should need a power beyond sleeve for this?

Oops... missed that... ok, never mind. :ashamed:

 

[stormpetrel]

So....what do I do?

 

[teg]

sorry, I just don't know how your tractor works... Seems that you should be able to put in Power Beyond and tap off of it... but I don't know how to do the hoses for your tractor...

Yep.....just a question of how, exactly, to hook the return lines up. I posted on the hydraulics forum. Maybe someone will be familiar with this situation.

Can any Yanmar guys tell me why I only have two lines to my loader valve, and how to run the lines for the new grapple valve.....?

 

[teg]

It might be some extra stuff to buy but I would check the pressure of the 2nd hose... if it's low pressure return... your 3ph is getting power somewhere else.
