Ford 7710 loader valve follow up

David G · Dec 13, 2015

I am posting pictures of the CCLS valve that I added to my Ford 6610

The first picture shows where I tied into the lines going from the priority valve to the remotes.
The second picture shows the joystick mounted on the fender
The third picture shows where the return line dumped in behind the seat
The fourth picture shows the CCLS valve mounted on the loader frame

I forgot to take a picture of the shuttle valve for the load sense.

The CCLS valve is a prince valve that I bought from Fort Dodge Sales, they were good to work with.

You can see the small sense line coming out of the CCLS valve, that goes back to the shuttle and tees into the sense line from the remotes.

Yep, that'll work. I would add something to the installation process that I learned the hard way: take a center punch and dimple the inside of the filler tube where the filler cap goes in, so the rubber has something to grab on to. When I first put something similar together on a 7610, oil shot out the rear of the tractor the first time I lowered the loader quickly. The filler plug could not handle the backpressure. If I had that install to do over again, I would route the return line to the engine pump inlet tube.

What size was your return line?

Mine is 5/8, and I think it is a little small, will probably go up to 3/4.

I used 3/4 on both inlet and return, and 1/4 on the load sense line.

I used 1/4 on the sense, 1/2 on supply and 5/8 on return, am thinking about upsizing the return.

This is what my Gresen V20LS valve install looked like on a 7610, BEFORE I cleaned up the hose routing. We put a 7412 Ford loader on it.

I just looked at your pics again. I would definitely upsize the return line, as well as look for an alternate location to hook it up. The port you currently have it hooked up to is for remote valve return. It is not designed to handle 20 plus GPM, which is what you'll have if a loader is dropped quickly.

There should be a plug higher up on the fill tube for a larger return, however I'd still look for a better spot as I mentioned earlier.

I am new to the site and doing the same thing to a 6610 the dealer told me that the tractor was a open center system and a closed center valve is not what i need. Are the remote valves closed center on these tractors?

Where did you get the fittings and valve what did it all cost thanks

The hydraulic system on those tractors is somewhat of a combination between open and closed center. The pumps are open center, and the remote valves are closed center. An unloading valve directs pump flow back to sump when there is no call for oil usage.

If you're installing a loader, you can use either an open or closed center valve. With an open center valve, you'd source oil directly from a factory remote valve. With closed center, you'd tee into the remote supply lines as discussed below, with the addition of a shuttle check valve.

Open center valve will be cheaper and easier, closed center will be more expensive and difficult to install. The advantage of a closed center valve is two-fold: 1) No oil will be circulating through the valve when you're not using the loader, reducing heat build up in the system, and 2) you'll get more volume from the closed center setup, since 15GPM is all you'll get out of one set of factory remote couplers. 18 plus is what you'll get using a closed center valve.

Not trying to nit pick... but to those who don't know the system we should probably always refer to it as closed center load sensing just in case someone goes out and buys a true closed center valve... because you and I well know that won't work either.
I know what he's running up against in trying to buy a valve... when you talk about open center system with closed center valves a lot of guys get a blank look on their faces and then don't want to order anything for you because they don't want a $1000 returned valve sitting on the shelf...

You're exactly right Rod - I should have been more precise in my lingo. Thanks for the clarification.
