Rear hub

Dan from WI · Jan 22, 2015

Greetings, I have not posted for a while and have had my 1948 8N parked for over a year while I try to decide what to do with it. I decided to get it running and fix the brakes. The rear seals have leaked badly and the brake shoes are impregnated with gear oil. I have new parts on order including shoes, seals and gaskets to try and remedy my problem. I also intend to check the fluid level to insure it is not overfull. One of my concerns is the hub in the photo I attached has a imperfection on the seal surface that I can feel as I run a finger tip over it. The photo looks much worse than it actually is. I am hoping this will seal up properly even if there is a very small groove on the surface. I plan to keep the tractor to do some light work around our place but am not wanting to invest a lot of money into the project. Any input would be appreciated.

John Smith likely has a good used one if needed so you don't
have to do the job and buy seals twice. Link Here
If he doesn't, I have one, but he's closer to you.

I'm wondering if they mke a speedy sleeve that would fit.
Anyone ever try one on this application?

I have not. My splines were wore out before the seal surface.
I suspect that may be typical, but I don't know for sure.

When I did my restore in 06 I found the same problem. I installed speedy sleeves that I purchased from a bearing supplier. BC bearings here locally in British Columbia. Im sure most industrial bearing suppliers can help you.Fairly easy to install but be carefull not to distort installing. Good luck.

The picture makes this look much worse that it really is. It only has a small indent that can barely be felt. I don't think the groove is more than a few thousandths deep and it is gradual with no sharp edges.

I have polished those marks out with fine sandpaper while the hub is spinning on a lathe...

Dan.......while the grooves in pix look pretty BAD, I think they are just NORMAL wear marks. Me? I'd replace the seal ...but... I would NOT seat the seal all the way into the axle housing. I'd leaver "proud" about 1/16-in. That'll gittchur seal lip on smooth metal. And unless yer using yer 5-gals of hydraulic fluid fer FEL, 4-1/2 gals is plenty 'nuff. Infact, 4-gals of Ford spec: M2C-134D hydro-tranny oil is plenty of oil. ........HTH, oily Dell

Dell has the right idea.. However if you have a lathe and a professional bearing supplier, you could just turn it down a bit and use a different seal. BUT you always buy the seal before turning the part so that you do not ruin anything...

I've done as Dell describes on many car and truck axles to save an otherwise good axle when asked to do so by a boss.

My thought goes to emery cloth in range of 400 - 600 grit and polish it.

That idea won't work because the seals he's using fits in a mounting flange and the depth can't be changed. Polish the old groove on the hub (on a lathe would be best) and put it together. It will be just fine.

Thanks John, It's pretty smooth already so that's what I'm going to do.
