Farmall MTA hydraulic pump

[rustred]

yes, but not off the bottom and it is filtered. totally different set up. much improved hydraulic's from 1950's to 1960's
 

[Dieselsbest]

Ok
 

[rustred]

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.
 

[Dieselsbest]

The cam shaft wont handle running the stock pump?
 

[DeltaRed]

A PTO pump is best for a loader. More volume and pressure. And you are not wearing out an expencive pump.
 

[Janicholson]

The cam drive gear is driven from the crank shaft at 2:1 ratio (2 Crank turns one Cam turn) the cam gear is plenty strong to also run the governor and the hydraulic pump, as well as the distributor. But it is not going to accept any more force applied than the stock pump as designed without failure of the gear (teeth strip, or the hub fractures) that causes major repair effort to fix. There are no stronger gears being made. So the answer is either a modestly slow loader, or a PTO pump with far more GPM and pressure. We that are responding to you have seen the issue form every direction, and are keeping you from making mistakes that degrade one of the best tractors ever made. It is OK to use a slow loader it is OK to put a PTO based pump on it for a fast loader. It is bad practice to overload a standard system, or expect the tractor to do service as a production loader that was built for that service. If you need rapid high capacity loading of materials, purchase a single purpose loader machine. Maybe a skid steer with 40 hp. Jim

I have an M that used to have the distributor mounted pump that was used for power steering and a loader. The loader was S L O W! It would lift about anything though. Until it broke the distributor/pump shaft. That's when we found that someone had replaced the pressure relief valve with a bolt so there was no bypass. It's amazing the cam gear never sheared off! That tractor has an old Du-All loader with a reservoir built into one of the uprights. Runs off a pto pump now since we eliminated the distributor pump and welded the shaft back together. It's been working like that for at least 35 years.

Ok may I ask what you mean by slow loader? Just how fast the hydraulics move? Its a WL30 loader if that helps

I have an SMTA with Dual 325 loader. I run it off a PTO pump (live PTO). I tried running it off of my tractor pump once but was disappointing. A friend of mine has an old M with a Lyons INdustrial loader for loading hay. He uses mag pump plumbed into reservoir on loader. It never seemed that slow.

DeltaRed,

The level of oil in the belly pump is much higher than what it would be in the differential housing, and it is much closer to the pump.
 

[caterpillar guy]

You mention the 560and newer ones use the rearends for a reservoir. Yes they do and the pump is right down in the oil or very close to that so lift point of the oil is only a few inches versus about a foot and 5 feet of hose to pull it through to the pump. And those newer tractors drive at the transmission with a stronger drive to them for more pressure on the system. Also they are only 12 GPM so not a fast loader with them either. IF you want a faster loader you need in the 25-50 GPM to lift fast with 2500 PSI to lift heavy loads or big cylinders to offset pressure being lower.

[Dieselsbest]

OK so if I do put a loader on it and use the distributor pump I will wreck the pump?

Ok , a loader covers a lot of ground here , what kind of loader , cylinder size , double acting or singal acting . one cylinder or two on the bucket of trip bucket. Once you get all the cylinders filled the fluid just really moves from side to side with vary little moving out of the resavor On the org loaders with only lift the back side of the cylinder was the make up oil . Last place you want to draw oil from is the rear end . You have no idea what nastys are hiding in there and when you start moving oil around this will flush them out of there hiding places . Let it suck up a cunk of chipped gear that has been hiding for 50 years get sucked into the pump it will trash out the timing gears in a split second locking up the pump. What you could do is add a tank off the hyd. unit ahead of the factor unit . Now remember ya only have limited psi coming out of the M T A pump and ya can['t push that pump past 1500 PSI and 1500 PSI does not have much lifting power on small cylinders . It will not even lift a four row John Deere 7000 no till corn planter with a 3x8 cylinder when loaded with Fert and corn . Now it will lift a 1240 four row with a 3X8 but they weigh a lot less i can not lift a 1219 J D hay Bine the minium to lift that is 1750 and then that is SLOW .

No why would it unless you starve it for oil . and who knows how good your pump is to start with . That can only be checked by putting the tractor on what is called a flow rater , this will tell how many gallons per min the pump can put out and what kind of pressure it and the pressure relief will let it make . If the pump is weak then it may not even hit the relief set . and NOT MANY GUYS have the flow rater to do this as that is something dealerships have . I am the only independent that has one anywhere close to me . A NEW pump will put out 12 gallon a min and org pressure was 1250 some have set them up to 1500 on a good pump but as they wear pressure and GPM start to drop. . SOOOo your guess as to how well your system is working is a craps shoot.
