Farmall MTA hydraulic pump

Im looking to use the rearend as a resivor and have it figured out, if the pump will pump oil up from the rearend end. Will it or is the oil not going to get to the pump? Heres some rough edited pictures to hopefully show what I mean. Thanks.

I'd think you could do that but a height difference between rearend and pump may be a problem. You'd want to ensure the intake side of the hydraulic pump stays flooded with oil.
 
Do you need the extra volume? Sucking from the drain plug will run metal from the transmission through the hydraulic pump with out a filter. Those pumps never were high flow or high pressure.
 
Three things! the pump may loose prime when parked for a while due to the elevation change. The sucking of oil from a sump is OK if it goes through a filter, not just a screen. The housing would need to be pressurized to push the oil up for priming. unless real Hytran is used it may be unable to keep moisture out of the suction hose, and even hytran has limited moisture absorption ability. In addition to that the hose would be subject to being ripped off in the field, loosing the contents of the final drive housing.
Why do you want to do this? Jim
 
I agree it is not a good idea, but three is a natural trap below the bull gear, but not sure if there big enough to suffice for what he wants to do,but either way your going to need to take the top cover off, and power was it clean first!! I feel its to low for a hyd oil supply!!
 
There's a lot of crud that can build up there & if something should happen, chipped gear, disintegrated bearing retainer, etc, you may have further problems. You can always add a tank somewhere to give yourself greater capacity if you need it.

What about the guys who use the belly pump for a reservoir? The 'mag' pump has to lift the oil in that application. I have an M with a 'mag' pump that uses the belly pump as a reservoir. Draw oil from the belly pump drain,return to the fill.Never had a suction issue.My good SuperM has the same (undre the gas tank) system as yours. I stripped all the guts from the tank. It is now simply a reservoir,hold about 2+/- gallons. I have never ran out of oil capacity.If I were to use the rear end as a reservoir(as you are wanting to do),I would drill a hole in front of the brake pedals do wn low on the flat part. Tap 3/4 or 1 inch pipe thread and draw oil from there. That gets the suction up off the bottom,reduceing the chance of contamination.Return to either the top oil fill plug;the check plug on the right side;or drill another hole just above the first suction hole.That would be my choice.As said,drain and flush before filling with clean HyTran.
 
not good! reasons are listed. distance , dirt and need a filter also, and filters are usually on the return to tank side. separate tank is the cats meow. as ihc had designed it.
 
Im looking to put a loader on it my great uncle has and I wanted the capacity so I dont run out or get the oil too hot
 
And WHY do you think you need to draw from the rear end?? I have a S/MTA and i have never seen the need for more oil . your sure not going to run and air seeder with a S/MTA where ya need 40-50 GPM And you will never be able to get more then around 1500 PSi out of that with out shearing the camshaft key and gear. .
 
yes, but not off the bottom and it is filtered. totally different set up. much improved hydraulic's from 1950's to 1960's
 
you will only need a larger oil tank, due to the loader cylinders volume. loader on this old tractor is not the best. i put a loader on my 560 and its no speed demon. u saying hot oil ,... never will happen. running oil over relief will get it hot hot in a hurry.
and the camshaft gear cant take high pressure anyhow.
 
A PTO pump is best for a loader. More volume and pressure. And you are not wearing out an expencive pump.
