Loud left final drive gear or Transmission 130 Farmall 1958

I just purchased a 1958 Farmall 130, it has a loud wining / growl sort of roller bearing noise coming from the left bull gears OR the transmission rear section, It occurs in all gears and even reverse,, it ONLY happens when there is a load on the tractor,, if its coasting or the machine is in neutral or my foot is on the clutch it does not happen,, if im in any gear and start to climb a hill it will get rather loud,, I leaned against the rear wheels and i can get them to rock parallel to the tractor like they have quite a bit of play in the cases..
a local tractor expert opend the transmission and pored almost 2 gallons of gear oil in her before we could see the bottom of the trans case getting covered..

( JUST ordered a manual off the site )
QUESTIONS:

1- is it true that no matter how much oil i pour in that transmission it will NOT get to the final drive gears..?

2- there are NO drain or fill plugs on the final drive gears... help? take the pans off , clean and then....?

3 - is there a procedure for adjusting the lash or bearing play without tearing the entire drive unit apart..?

4 - ANY expertise in any of the diagnoses is welcome,,

DID i buy a lemon,, ???? ))

So much for your local expert. There is a level plug on the left side of the tranny and it doesent take that much for a fill. There is a plug in the final to fill them as they do not get anything from the tranny. To drain the finals remove the bottom pan then you can fill thru the plug with 90wt. Your bearings could be bad if the wheel will move in and out. You can remove the axle and check the bearings if you have side play or even in and out as there should not be any play either way. Splines could be worn on the axle where the bull gear fits also but you will not know untill it is taken apart./ When you have the pan off it can be checked easy but something is wrong according to your post. Those are good tractors and only being 60 pluss yrs old things do wear.

I swear I checked EVERYWHERE and cannot find ANY fill plugs on the final drive cases,, left or right...?

any thoughts on where the 2 gallons went... eeeekkk?

The plugs on the final drives are on the inboard side. They are removed with a 3/8"(I think) ratchet. Might be a 1/2". That oil almost never needs replacement. You could pump it out and refill it. It'll outlast you.

That transmission takes 6 quarts of gear oil if it has a PTO, no PTO takes 5 quarts. 80w90. NOT, NOT, NOT straight 30 weight like some "experts" seem to think.
Due to the age and wear, I run 85w140 in my tractor transmissions. They quiet up a bit and shift much easier.

man I cannot see them,,,
is it possible they are covered by the tow linkage plate,, ?? I see no place for them to be,,?

also next step is to drain the trans to the correct level then,,?? plug on side under seat,

doesn"t sound like trans issue to u..?

Every "A" series tractor I have ever driven has a loud transmission in all gears. My 140 is a bit louder but thats because it was full of water for XXX years. They are not quiet. Without actually hearing it, hard to tell if thats normal noise or not. My A was loud, my 140 is loud. Tomorrow if I remember, I will post pictures with arrows pointing to the drain and fill spots but remember, on the final drives there is only a fill point. In the middle of the case, right over the pan...

The fill plugs on the final drives are near the group of three mounting holes on the inside. One is near the front on one side (left?) and near the rear on the other side.

Pans have to come off to drain.

If you can rock the tractor, and it's NOT just the tires flexing back and forth, then you need to replace axle bearings. It's not something you can simply "adjust away."

More than likely your drawbar mounting plates are covering the finial drive fill plugs. And as far as the whining noise is concerned I would say you might as well plan on putting new bearings in them. My 49 C was doing the same thing just on one side and a new set of bearings fixed it and these small tranny"s seem to have a slight whine to them anyway. But hold on tight to your check book the bearings for my C were over $500 for 2 bearings and 2 seals. (Sorry for the bad news.)

Plug is behind the left brake rod for level extra lube is probably leaking into the diff shaft housings and will screw up the brakes coating them with lube there are seals but wont hold an overfill.

Ditto on the drawbar mounting plates covering the fill plugs (level plugs).
Good news is that axle bearings for the 130 are cheaper; approx. $100 for the outside bearing and approx. $40 for the inside bearing. The seal adjacent to the outside bearing will run $30 or so.

Yup, I checked my Super A last night and the plug is behind the drawbar mounting plate on one side.

It's right smack in between the lower two mounting holes on the final drive, either front or back, depending on the side.

finally some good news.. BUT are they bad for sure..? cant you try to take them apart and shim them ..? or...??

These are standard single row ball bearings. No matter how frugal one is, a worn ball bearing can only be replaced by new.
If you run the tractor with badly worn axle bearings you may damage the bull gear and the gear on the differential shaft.

ok,, thanks,,, BUT there is good news,, if you read the very first post of mine ,, my EXPERT tractor guy pored about 2 gallons of gear oil in the trans,, ill drain that,, BUT now im understanding that there is HOPE that the left drive could still be low / dry cause I never pulled the pan to see,, he told me that the oil would cascade down to the drive gears,, and now I see it cannot cascade and there is a possibility it just needs oil,,, so that's a GOOD thing as it pertains to me trying to quiet a noisy final drive gear.. ) yes ?

I agree that the final drives are separate from the transmission, meaning that they need to be filled and drained separately.
I also agree that heavy gear oil reduces gear noise. Heavy gear oil may even reduce the growl and whine of a bad ball bearing.
However, heavy gear oil does not "repair" bad bearings; the bearing play will not be reduced any by using heavy gear oil. In other words, heavy gear oil is not a substitute for new bearings.
If you need help in replacing the final drive bearings, start a new thread. It is not a difficult repair. There are even older posts and photos in the forum archives.
HTH, Hendrik

Agree with Hendrik.

If it's dry to the point where it's wobbling and making noise, oil is NOT going to "heal" it. The damage is done. Only options are to repair or scrap the tractor.

All excellent advice. You need to remove that final drive get someone competent to inspect and replace any worn seals or bearings. There is no substitution for being thorough when you have that kind of problem. It sucks. I know. I just did my light-side. All my bearings were good, my seals were toast. Leaked and slung so much oil it somehow ruined a perfectly good brake band. Seals got replaced, a new brake band was installed and added heavy gear oil. $450.00 later + the price of the 85 140 gear oil from tractor supply, a dip in the hot tank for the wheel and weight, rattle can and I couldn't be happier. I'll post pics later.

Do it right. Don't mess around.
