ford one arm loader

[Kirk-NJ]

Looking to change the one lever valve to a two lever to oparate the hydraulic dump bucket. I would like to use what I have and add to it. Any ideas are welcome.
Thanks, Kirk

Welocme to TBN

Look up post's from user "soundguy", he has two of these loaders and can probably help...

Those cylinders appear to be single action cylinders.

Yep, old ford loaders used single action cylinders, My okd Dearborn loader just jses the weight of the loader to return it to the down position..

I have never seen this before, but just looking at it, I am going to take a guess on how it works. That valve is a single action valve with one pressure in port, and a release port, and a hose going to each cylinder. When the lever is activated, fluid goes out to both cylinders, and I believe the smaller cylinder activates first, then the large cyl. In the dump mode, the lever is shifted to release the fluid in both cylinders, and the smaller cylinder dumps first, dumping the bucket, and then the larger one. Now, someone really tell me how this thing works.

I found this.

I don't know for sure how this system works, it may have 2 valves. The Dearborn bucket has a mechanical trip. The single action cylinders expand when the valve is activated and release when the valve is closed. In the case of the old 8N, this action takes place by putting a line into the system after the 3 pt. relief pop valve and chaining down the 3 pt. hitch lift arms. When you activate the system, the relief valve pops and the pressure goes to the loader cylinders.

Kenny.. i got about 6 of those 1-arm loaders now

here's the skinny.

the big lift cyl is SA

the small dump cyl is DA. that one looks like a red lion or other 'tsc' sourced cyl.. might be something else.. etc.

the common Ford and tisco style top cover valves come in 2 flavors.. single valve ( dual acting ), and dual valve (dual acting). the single ones usually have an adjustment to make them function as SA. the dual valves usually have an adjustment to make ONE of the ports operate SA... I have seen single acting only valves... but IMHO.. they are less common...

on the dual valves, setup one port as SA and then use the SA port for the lift cyl.. and the da port for the dump cyl.

if you have a single DA valve now.. you either need to swap it for the dual valve.. or run an aux dual valve off that single valve, and bunji it open unless it is a detent style valve.

NEGATIVE on that.

when you chain the lift arms down, the 3pt piston can't move.. fluid is then forced out the TEST PORT on the right front of the pump base plate and run out to a SA cyl.. when/if cyl maxes out, then the relief in the belly pump opens... remember.. the relief ont he pump vents directly to sump.. it's a spark plug shaped thing screwed right into the aft of the pump...

dropping the 3pt contrl allows the cyl to exhaust.

that blue valve in the second pic looks like a selectrol valve.. can't see it well enough though..

I thought they were single action cyl, because there are only two hoses from the loader.

Guess I am a little behind the times

 

[Soundguy]

I thought they were single action cyl, because there are only two hoses from the loader.

other hos(s) may just be obscured. SA on a bucket would make for a difficult setup between having to have a trip mechanism AND a loader control.. etc.

here's a pic of the dual valve on my 660.. one side is setup as sa ( small knob adjustment ).. and only has one line on that side.. this si the lift side.. the other side is 2 hose and is the da for the bucket.

here's a pic of my da bucket cyl.. real close looking cyl as to the OP's..

Hijack Alert!
Doggone J_J ! I like the new look! You clean up pretty good! Maybe there's hope yet for this bearded Buffalonian! Hope ya didn't 'Bet the Beard' on the Tampa game!!

 

[ToadHill]

J.J. what happened to the beard? Soundguy, thanks I tried to explain it best I could, I just know how the one on my old 8N is hooked up, I wasn't familiar with what is going on inside the case.

 

[Soundguy]

respectfully....if you thought / think that you are going into relief to get the loader to lift.. then you -don't- really know how the one on your old 8n is hooked up.

it's a simple physics deal... fluid follows the path of least resistance.. pump is pumping, intake valve is open, exhaust valve is closed.. piston can't move ont he 3pt.. but the piston onthe loader can.. and does.. till it maxes.. thent he last thing left to go is the relief.

Yes the other valve is a ford (fomoco)selectrol valve.

So I can add a single valve to what I have to operate the lift arm? If this is true where would I make the connection? Do they sell an SA valve or should I buy a DA valve and use the one I have for the SA?
This would have been so much easier if the PO just sold me the valve off his tractor. I offer him money plus my replacement valve, and he wouldn't go for it.

Thanks, Kirk

since you have a loader needing dual valves one sa and one da, and you have a selectrol valve and a single da valve available.. you got 2 options.

use the selectrol diverter valve to run a hyd line out to a dual valve, and then plumb the return of that dual valve back to the sump with a fitting into the dipstick plate... lift the 3pt handle to start the oil flowing to your open center loader valve. this valve won't see 3pt lift loads as it will be isolated by the diverter, so a cheap-o 120$ log splitter valve that is oc and has one da and one sa configurable port will work.. just pull the knob on the selectrol to cut hyds from the 3pt and send them to the laoder.. and vs-vs.

or.. use your da single valve as a feed for a dual valve setup that is pb capable, as it could see 3pt loads.

lastly.. you could get a sandwich palte that goes under that single valve you have.. use that valve for a remote and then plumb in a power beyond valve off the ports on the sandwich plate.. thsoe plates go for about 100$.. plus whatever the laoder valve is.. probably 120-150$

lastly.. you could just keep looking for a dual ford valve to fit the top cover... used ones int he 300-500$ range.. new in the 700-800$ range.

Thanks,
Good to know. Sounds like you covered all my options. Since I have other loaders and I don't need it right now I would like to try to get the right double lever valve for it. I was out bid on one on ebay and just missed the one on the N board. So they are around and do come up from time to time. There's a swap meet coming up in Oct. Maybe I'll be able to find one there. I'll let it sit over the winter and be looking to do something by the spring. If I don't find it by then I'll go with one of the other options.
I 've got to cut and split wood now. Winter will be here before you know it and my wood stove will want to eat.

Thanks again, Kirk

the valves come up often. I've bought a couple ford valves just inthe last couple months myself.
