Missing bearing cover

Postby Scott in ME » Sun Nov 03, 2019 11:23 am

I'm embarrassed that I just noticed this now on my Cub. Look at the two photos. The first is of the sheet metal cap that covers the wheel bearing on my left rear wheel. It appears to be held in place by several bolts. The second is of the same spot on my right wheel, where the cover is missing. I can't imagine how it would have come off, as the bolts are still in place. Perhaps a previous owner removed it and I was too blind to notice. Two questions: what is this cover called, and where can I find one? I checked Steiner Tractor, and perhaps searching under a wrong name, found nothing. Any advice on finding one would be greatly appreciated. Thanks.

that is the way its made, that is exposed so a drive gear for the planter can be bolted on, you do have a nice oil leak going on

Yes, that is the way it is supposed to be, though a tad less oily! The is an o-ring on the shaft under that castle nut. Not sure if you can replace it without further disassembly...perhaps someone can advise.
Or, just clean it off and continue. When it stops oozing, you need to refill the final oil pan with more gear oil!

Is that mess coming out from my transmission oil supply - the one that fills from behind the gearshift? It appears to be all one piece.

Yes, and often condensation will raise the fluid level above the seals. There is a level plug on the side of the tranny that you can remove and see if you get a milky oil/water mixture out indicating it needs to be drained and refilled.

Looks to me like the leak is coming from above, not at the seed plate drive. It would have to be if it were oil from the transmission. Search for any threads that mention oil and brakes for previous discussions.

Hi,
Below is a page from the 1949 Cub owner's manual, telling about the Seed Plate Drive, on the right final drive.

http://farmallcub.com/rudi_cub/www.clea ... age-48.jpg

There is an oil seal in the right side cap, TM Tractor has a new seal, but it may not be leaking much there.
If oil is running out from above the Seed Plate Drive, the transmission oil may be too high, check it like was said above. It should be filled only to the level of the level plug hole, low on the left side of the trans. It is common they get water in them, you could change the oil, if you haven't.
The drain plug is visible from under the platform.
Or the trans or final drive oil seals are wornout and leaking, on the final drive upper shaft, the shaft the brake drum is on.
There should be no oil there, the areas where the brakes are should be dry. They are areas between the trans and final drives.
The brakes probably don't work with oil on them.
It is common to need to replace the oil seals, they wear out after years of use.
TM Tractor has new seals.
You could give the Cub a power wash, so you can see where the oil is leaking from better. :)

I can't quite see in your pics, it looks like the Cub has a different than IH drawbar on it.
Below are pics from TM Tractor of the IH drawbar, if you want to look at the pics.
They have brackets that space it down from the final drives.

Thanks for the information re: the drawbar. I have always wondered why mine does not seem to fit correctly. Yes, a good washing is in order before it's cold enough to freeze the water. I took a photo of the area around the drive gear, to give a better idea of where the leak is coming from.

Drawbar brackets use a special tapered bolt, don't want to break the holes in the finals.
Nice pics :)

Hi,
Two of the holes in the drawbar for the bolts that hold it on the brackets were originally for 1/2" bolts.
It looks like in your pic that the drawbar holes may have been drilled out to 5/8", so it bolts to the final drive.

Below is a page from the Cub parts manual, showing the drawbar. Numbers 1, 2, 3, and 5 are the Swinging Drawbar, it is extra.
The standard drawbar is numbers 4, 7, and 8. The 1/2" bolts are shown below number 8 in the description.

http://www.farmallcub.info/manuals/cub_ ... 009-02.jpg

I don't know what size the holes for the 2 pins are, it doesn't say.

Below is a listing at TM Tractor for new drawbar brackets, you can look at the pics.

http://www.tmtractor.com/new/gb/489fp.htm

You could cut lengths of bushings, the right size and length to fill the extra space, if you put the brackets on, and use 1/2" bolts.
Or buy a used drawbar, with the brackets. :)

The brake is in the housing where the hole is in your pic. There is also a hole in the front, where the brake rod is. You could use a light and look in, and see how much oil is there.
The area where the brake is should be dry.
