Hydraulic problems for an H

Fuller's Farmalls · Jan 5, 2011

I finally got some oil for my filling my resivore(the old oil had water in it). drained all the fluid, lowered the loader and drained the rest of the oil. Then filled it up and raised the loader a quarter way to and filled until the resivore was full. I put the cap on and lowered the loader. Then where my cap is oil shot out. Is there suppose to be a breather hole in the cap. And when the new oil shot out it was still milky. So I'm between a rock and a hard place here. What should i do?

The oil in the hoses and cylinders is also contaminated.

Your problem with oil coming out was the fact that you raised the loader and topped it of.

Those things only hold about 6 quarts.

6 quarts is often not enough to raise these loaders all the way, so they have auxiliary reservoirs.

If the loader uses the tops of the cylinders for auxiliary reservoirs, the cap should NOT be vented.

Problem is, you don't know what you're looking at and we can't see what you're looking at, so there's no way we can be 100% sure of what you have.

There should be hoses running from the fill pipe on your belly pump, up to the tops of the hydraulic cylinders, if they are being used for auxiliary reservoirs.

If there are no hoses running from the fill pipe on your belly pump, then it does not have an auxiliary reservoir. 6 quarts would be all you need in this case.

I have the extra hoses running to the tops of my cylinders. So I should be good with plugging the hole on my cap?

Unless the top of the cylinders are drained (usually removing the cylinders and purging them then reinstalling them) you will have some residual milky oil in the system. This would dissipate within a week if the tractor was used and the oil heated to evaporate the moisture. Casual use would not do this, and winter use will slow it down.
Put a hose on the filler cap stand pipe. put the end of this hose in a bucket of the Hydro oil you are using. work the loader through its range of motion slowly and both air and excess oil will be removed. When it seems stable, remove the extra hose, and drain about 1 quart out of the reservoir. Button it up and there you are. Jim

It sounds like you probably have single action cylinders as most older loaders & tractors had originally, oil only fills the lift side of hydraulic cylinder, your are overfilling the reservoir of the tractor when you raise the loader partially, when you lower it the oil comes back out & has to go somewhere, this is one reason double action works well as you are transfering oil in the cylinder from one side to other. Single action has 1 hose in base of cyl.

If the system is plumbed correctly, the hoses coming from the tops of the cylinders should be returning the "extra" oil from the tops of the cylinders to the pump reservoir when the cylinders are extended. If that's the case, then yes, the vent hole in the cap should be plugged.

I agree with the others in that the oil in the tops of the cylinders was/is also contaminated with water, and that contaminated oil was returned to the reservoir via those top hoses when you raised the loader the first time after putting the new oil in.

Fuller, you did not specify the model of loader you have on the "H". I have a McCormick-Deering Power Loader, No. 30. I also have the Owners Manual for Setting Up and Parts List. I no longer have the H, but, I do have the hydraulic hose assembly and return plumbing assembly. Contact me if you are interested in any thing I have listed.
