Farmall M Loader Wont Lift (Pics & Video Inside)

Faster346 · Apr 11, 2011

Hey guys, I put a New Idea Horn Draulic loader on my M today. It was said to work fine, but it's been sitting out back for years. Anyways, I hooked it up today. It all went pretty smooth, except for it wont raise more than about half way. I pull the rod and it takes about 10-15 seconds, then the loader starts to raise, and stops about half way up and wont go any further, which isn't going to be any good for me if I can't dump a load into the spreader. The lines are plummed from each cylinder into a T fitting, that goes to my remote hookup which is plummed into the passenger side front fitting coming out of the Lift All. The dipstick reads FULL and the fluid is SAE ND 30W. So I'd like to find out if this is an issue with my tractors hydraulic system (never had anything hydraulic operated on it before) the loader itself, or my plumming. Thanks!

Couple pictures. Video wont load, so I'll try to rehost it and edit it in.

And this is as far as it will go up.

My dad had a loader like that on a SMD, and maybe now I know why he had an auxilary oil tank on the hydraulic tank.

Add a aux oil tank in line. I had a Super C with a loader. It had a football shaped tank added above the filler hole, then you filled the top of the resevoir -oil ran into the filler cap of the pump and kept it full with rams extended.

I have an identical loader on an H that will lift all the way up with no auxiliary tank. You may need to move the front frame bracket forward. Your cylinder appears to be partially extended when the loader is all the way down .

You're running out of oil.

Don't keep trying or you'll burn up the pump.

Let the loader back down and top off your reservoir. Fill it right to the brim.

I bet you'll find that you're down 2-3 quarts, which is 1/3 to 1/2 of the tractor's total capacity.

Those hoses were dry, and so were the cylinders.

The dipstick reads full..but I should just fill it to the top? Someone told me to raise the loader up, shut the tractor off, and try checking the fluid level then, and adding accordingly. Is this safe to do with the loader raised? I didn't know if that cap is under pressure at all when it has a load on it with the loader being up.

Threr is air in the cylinders.
Put them flat or top down by disconnecting them and gently run them out, then in by hand pressure, then out an in. This should purge the air. Do not lift it and add more oil, you will have a serious mess! Once purged it should be fine. Jim

I will try this! Is there some sort of way to prime the system? I mean there's like 8 feet in hoses, so there's always going to be some air in them, wont there?

I have a 47 farmall M that I mounted a 2001 IH loader on......basically the same setup you have there only with new type frame. I dont have a auxillary tank and the loader will lift all the way up with no problem. We filled the hydraulics too the top and have never had a problem.

NEVER....fool with that trator with the loader mounted and in the raised postion without some means of support!!!!! Make yourself a safety sleeve that goes over the hydraulic cylinder in the raised position......install the sleever around the shiny part and let the loader down against it. This is the same thing they have on all the newer type backhoes and they work great for servicing.

Fill the resevoir a quart at a time with the loader on the ground. If you fill it with the loader up in the air all the oil thats in the cylinders will over fill the resevoir when you let the loader back down and make a mess all over your tractor and the ground. chris

Janicholson · Apr 12, 2011

Working the cylinders will get the air out almost completly. No issue will remainIf you still need more reservoir capacity a tank with vent can be mounted to the loader (non moving) frame and plumbed into the drain plug in the bottom of the Belly pump. a "T" fitting will alow both drain and supply of added volume Jim

Check the oil with the loader up as high as it will go.

If it's empty, then you need an auxiliary reservoir.

If there is still oil, the air bubble might be your problem.

Those hoses will require some oil to fill them, so your reservoir will end up going a quart or two low once you get all the air out.

randy hall · Apr 12, 2011

you will run those cylinders up and down till the cows come home and they will never work the air out of them. there is a 1/8" pipe plug at the top of the cylinders to bleed the air out. you need to fill your hydraulic completely full with the loader down to lift it all the way. i have had a horn loader on an m for many years. they are the cadillac of the trip bucket loaders. mine will lift a five bottom plow and put it on the trailer.

The fill cap is never under pressure, that's why there is a vent hole in the top. The dipstick is meaningless when a loader is installed. The best place for it is on a shelf somewhere in your shop.

Raise the loader as far as it will go, then cut a piece of 2"x2" angle iron as long as possible to fit the rod end of the cylinder. Use a hose clamp to clamp it to one of the cylinder rods for a safety before getting under the loader or sticking an arm through it anywhere... cheap protection!

Hey Randy, this is Lance, I met you when you picked up the 706 with Todd. How do I bleed the air out? I'm new with these loaders. Do I raise it, and then bleed it out until fluid comes out, or leave it down and raise it with them open and close them when fluid comes out? Do I do one at a time I'm guessing? Thanks!!

randy hall · Apr 13, 2011

lift the loader up a little and open the bleeder screw a little and when oil comes out close it. one at a time unless you are much more corodinated than i am.
