F10 loader gpm requirements

Madalien · Apr 3, 2010

I have a 1950 Farmall M with a farmhand f-10 loader on it. I would like to make the hydraulics live but am unsure of the pressure and gpm requirements. if anyone could help I would be most appreciative.

Well you have some limitations:
The Liftall is about 5GPM so it will be slow.
Double that and it goes twice as fast.
The IH front (distributor drive mounted) pumps have 1200psi, but not much more flow, maybe 7GPM, I cant remember. The 1950 will need a front cover and heavier (late model gears) to accommodate that pump. M&W made a pump that fits the housing, but you still need the gears to reliably drive it without breaking the cam gear. The M&W Pumps are also rare and expensive and used, as well as not having either high pressure or volume.
A belt driven pump will need a good 5/8 wide V belt, or "gilmer" cog (like a timing belt) belt to handle higher pressure higher capacity. A PTO driven pump (or belt pulley) will do both the pressure and be able to put out 12 or more GPM. but not Live.
Good luck, Jim

thank you I think I am going to try to put one in front of the engine for direct drive. I will have to build and engineer a bracket and coupler but I think it can be done.

The Farmhand PTO pumps are 22 gpm. Couple up one of those with a chain drive and you will have something.

you have a really good idea but do the pto pumps have a max rpm of 540 or can you run them faster?

Janicholson · Apr 4, 2010

If run more than 120% there might be issues with its life span. a 1:3 ratio would be fine. The setup to use a pump on the front is good. The biggest difficulty is in either positioning the pump to clear the frame rails on either side, hanging it down under, or making a reliable constant velocity joint to use the hand crank shaft hole. I would use a surplus hydro pump designed to run at 2000 or more RPM, and a cog belt drive in front of the front pulley. I would also probably use an electric thermostatically controlled fan to allow more room in that area.

I converted my M to live hydraulic with mag drive pump and run it for many years feeding cattle every day. Mag pumps putout 12 gal/m which is half of what the yellow farmhand pump putsout. You will find your loader operates faster because you not going in and out of gear on your tractor to raise the loader. Everyone says you must change to heaVY TIMING GEARS and a diferent front cover. I never did and had no problems even with temps as low as -45 in NDak. I recomend you find a mag pump and enjoy your much improved tractor loader combination. You will never go back.

do you know where I can find a mag pump for under $500. I know they are hard to find and expensive that is why I am looking for other ways.

IIRC the distributor drive pump is 12GPM.

Thing about it is, they're so expensive that you can't even get a used one for less than $500. Used ones are a crap shoot because if you get a bad one it can't be rebuilt. Then you're into it for the price of the junk pump plus another $800 for a new replacement.
