Farmall 400 TA questions

[montidale]

I am working on a 400 with TA I’m not familiar with the Tractor. My nieces boyfriend got the tractor from the family farm. They want to use it to backblade their driveway. It won’t see much service. I’m just trying to get it running for them. From what I gather if I fill up the transmission and differential the oil will flow to the torque amplifier? Or does that have a separate Reservoir? From what I can tell everybody went to Hytran. Also the independent power take off uses hytran but has its own reservoir? At Fleet Farm they have various hydraulic oil’s. Is AW 46 good enough hydraulic oil or should I use something like Lucas Universal hydraulic and transmission fluid? I’m just interested in what you guys run for fluid.

th aw 46 is only for the hydraulic reservoir, the trans and diff need the hytran or equivalent oil. the t.a is in the trans housing , nothing is separate other than its clutch . fill trans and diff by removing the plate opposite gear shift.

You would only bother with using two different fluids if the hydraulic implements are shared with other tractors that use AW46. Otherwise it makes no sense to keep two separate oils around.

The "Farm Rated Universal Tractor Trans-Hydraulic Fluid" that Fleet Farm carries is a Hy-Tran compatible oil that is suitable for use in older IH tractors like this 400, both in the transmission and the hydraulic system. Just use that.

Thanks for the replies. Next time I get to town I’ll have to stop at Fleet Farm and get some hydraulic oil. I hate to start it up without everything being topped off.

If it's got any in it at all it won't hurt to start it...

If you operate your 400 in cold weather I would only use fluid the meets or very close to hytran in SAE spec which is close to SAE 15. I had no trouble with thicker UTF in hot weather. You have to read the msds sheets.

Don’t forget these ta tractors came out with gear oil in the trans. My 400 still has the original gear oil in it. Ta works good. But I don’t use it in winter. There will be no problem with hytran in the winter. Even the tractor running warms the oil up.

When I check the levels, the fluid in it right now is hytran. I drained out about 2 gallons of water out of the transmission and the PTO. We are up in Minnesota, so it freezes pretty hard in the winter. He couldn’t get the tractor to move last winter because the bull gears where frozen in ice I imagine. I spent half a day just chipping off the old crud and grease. The tin and the back blade is still up at the farm. I’m gonna have to take the fuel tank out and get it cleaned out. It looks like it’s been well used. It’s a little bit too big of a tractor for his place, but it should work OK for blading out his driveway. I drained the PTO and put new hytran in it. I don’t wanna drain the gearboxes until I know he’s gonna want to keep using the tractor. I don’t think he wants to spend a lot of money on it.

Sound fair . U can leave the trans and diff plugs loose only screwed in one turn and the water will keep dripping over night. Oil is expensive. So is repairs.
