Farmall M live hydraulic project

Since David G posted pics of his H live hydraulic project. So thought I would post the modified M project of mine almost finished. Works good with a 5 gallon capacity.

Hydraulic operating handles in easy reach.
Hope no one minds me clutering the board up with the pics.

The more pictures the merrier. Great work.

I'm curious though about that vertical peice of channel iron looking thing.

What is that?
 
Maybe the quick attach loader frame. I mostly just use it for lifting heavy objects or pushing snow it was a trip bucket frame. Since it has single acting cylinders I have a valve mounted on it that stays with loader when off tractor.
I just run it of one remote valve on the tractor, you can see the unpainted bracket and rod I use to hold the tractor remote in engaged position when using the loader. When loader is not in use the quick couplings on tractor valve can be used for other things. Primer painted frame work down lower supports loader frame and rear hitch from the swinging drawbar anchor holes. Everything is not pulling or pushing soely on the axle housings that way.

Glad to see another fabricator getting creative with the hydraulics. Can't figure out what the flatbar lever near the turned around 400-450 reservoir does. Maybe goes to a selector valve.

Filter is a nice touch. Malleable elbow on pressure line not so nice but I think you are safe with the limited pressure of the IH distributer pump. But I am sure you knew that.

Seems like the duplex valve with the "made in USA" sticker is probably a snow plow valve - one single and one double acting circuit.

Do you have another gas gear that attaches to hydraulic pump shaft? It runs the service meter. Diesel gears aren't that hard to find.

Nice job.
 
I see, you're using the under tank reservoir in series with the old belly pump reservoir.

To clarify, the capacity of those two together is about 5 gallons?
 
Yes with the top tank about 1/3 full and the lines. No hydraulic expert but was thinking the hydraulic oil would have more time to cool before going back through the pump.
 
Wardner think its the 9 speed trans. shifter you see. Lever where shaft goes in can be seen at the rear end of valve in one pic. Rear was completly torn down to bare housing with new seals and any bearings needed. What started out as a simple project to remove the loader from one M getting run down and needing work to insalling on another one turned into more work than I first planed.
Pressure is set at 1000 PSI right now. Going to see if thats enough. Run loader on another M from the belley pump for years and could lift about all the tractor wanted. If its not enough pressure I will turn it up to 1200 or 1250 PSI.
All of the valves are double acting. One mounted to the loader has the one pressure port looped into the return line when lowering.
One on the tractor has float which Will go to the rear hitch when I get it ready.
Don't remember, would have to look on the gas gear.
 
BE CAREFULL JACKING THE SYSTEM PRESSURE TOO HIGH !!!!I have been warned that setting it too high is VERY hard on the timing gears when using the "live"pump under the distributor.I have heard of then shearing bolts off???

Maybe someone more knowlegable than me on this subject could "chime in" on this ????
 
Very nice hydraulic job you preformed on the M. I agree that you would not want to raise the PSI too much. The pump and components will not like 2500-3500 psi like the newer equipment. Just use larger piston cylinders to do more work.

I have my Farmall 504 at about 2200 psi for loader work. I'm thinking about upgrading to 3 1/2" lift cylinders and 3" bucket cylinders. Then I will break the Speeco WFE! I have upgraded to a 17 gpm pump and high capacity filter though.
