Hydraulics questions

I also think the 2 or 3 spool valve is the way to go...
As far as hoses, they can be managed like MAD said, it's all in the planning.
Here are two pictures of my 2 spool valve:

You could add just a 2 spool for the rear, and a diverter on the FEL to operate your grapple, here is the thread on my install:http://www.tractorbynet.com//forums/showthread.php?t=48310, you can also find a lot more if you search for "diverter"

My existing single spool valve on the fender makes a lot of noise when in operation. Is this because it is too small for the flow required? Or because it's just a cheap valve (which it is)?

Could be just cheap, or could be to small. Do you know the specs?

Anything in particular to look for in valves? There are lots of options out there, and without seeing them in person it seems like kind of a crap shoot as to which is better than another.

The Prince SV stackable valves would work real well for your tractor.

1) This is probably tractor specific, but what do I connect these two new valves to? Do I need to buy and install a manifold or something to get the extra ports to connect these valves to the existing hydraulics on the tractor?

How is your 1 spooler plumbed now?

I used the JD PowerBeyond kit to hook up my remotes as detailed in the link I posted in the previous post. If this is the way way yours is now, your just need to replace the 1 spool valve with the 2 or 3 spool valve.

Some pictures of your setup would be worth a thousand words, literally!

It's one valve with 3 spools. Your existing 1-spool valve is connected in series with the loader valve. The loader valve power beyond line goes to the inlet of the new valve. The power beyond of the new valve goes to the 3pt. The tank return outlet of the new valve tees into where the loader valve tank line goes. All the plumbing can be virtually out of sight.

A squealing valve indicates there is a problem inside the valve. It could be many things. My dozer valve did the same thing and it was a blowby on one of the work port relief valves.

A 2 or 3 spool Prince SV is a great choice for your tractor.

The stack valve sure looks like the way to go. How can I tell if I have #8 or #10 fittings? Would it be reasonable to assume I have #8s, given I have a pump that is only capable of 8.5gpm?

Does this look right?

1 - SVI15
3 - SVW1BA1
1 - SVE22
1 - 3 section tie rod kit

That's exactly what I have. I believe the spools are option "B" from Surplus Center.

It really doesn't matter what size fittings you have as adapters can be had to change just about anything to just about anything. BTW, a #6 is 9/16 -18, #8 is 3/4 -16 and a #10 is 7/8 - 14.

When you have pretty much figured out what you need fitting an hose wise, go to Discount Hydraulic Hose and order from them. They also have downloadable catalogs that you can use to help you choose fittings. The guy there is very helpful and can answer just about all your plumbing questions regarding hoses and fittings. Just make sure you get swivel fittings on both ends of your hoses as it will make it much easier to install.

once again mad, thank you for educating us all. To any new posters out there when madreferee says " It wont work" or "In my professional opinion" you should listen too him. when he says you could do it that way but I have a better/cheaper way listen too him. I have learned alot lot on this board and when it comes to fences ask harve, when you want a pond or a lesson on rebuilding a dozer ask eddie, when you want hydraulic help ask mad.

AMEN BROTHER.

As soon as I saw this thread I thought of him and as I was reading i realized it was an older thread he had posted in already.... I think my standard answer for hydraulics questions will be to search for posts by mad cuz you will find the answer there somewhere.... I d@mn near cried as I got to the bottom of the thread.
