"No Name" model rear axel seal

[barnsworth 1]

Hello everyone.  New/Old member. Lost my account so a new one I hope I can remember this one!

 

I have a 1973 "no name" model, 8 hp 4 speed.  The rear axle seal has been leaking and finally blew all the way out and was riding around the axle itself.  Not ideal.

 

I pulled the hub which didn't go well but that's beside the point.  Pulled what was left of the old seal out/off and when I looked inside where the seal sits, I saw what was in the image. There is some kind of edge in there that the seal sits on?  Or is that part of the old seal? 

 

I tried to find the correct exploded view for this particular tractor, and I know it's here someplace but for the life of me I can't find it.

 

Thanks in advance for any assistance you can give.

I think the bright metal ring that is broken is really what is left of the axle needle bearing....  Bad news.. Is the axle loose meaning any up/down fore/aft movement a little in and out is ok

Unfortunately, I can't. I tried every email address that I currently have to reset the password and none were found.   The only other account may be barnsworth@frontier.com which I no longer have access to. If you can merge that account, if it is the account, I'd appreciate it!

 

Thank you!

Oh no. Yes, there is a little up and down movement. I am assuming that there should be exactly none?  It is less that the in and out movement if that is of any help.

 

If that is the case I'm up the creek so to speak. That is well beyond my mechanical abilities.  I hate to put her out to pasture, I've owned it for I'd guess, near 30 years.

I did a search in the admin panel and didn’t find any accounts like this. If you were a member prior to 2011 it is possible your account is still here but the email is not. You can always post in the talk to the moderator section for a more private discussion to get your old account back

As Paul stated, there should only be in & out movement, none allowable for either up & down or side to side..... Just replacing the seal with a bad bearing behind it is a waste of effort & money.... If the bearing is shot, the axle may be roughed up & need to be replaced. IF any of the needles in any bearings got loose inside, gear damage can result. Only way to know is to pull it apart.....

To replace the bearing, the Unidrive needs to come apart. Or.... swap it with another good 4 speed.

There are some excellent instructional documents in the Transmissions section that cover the teardown.

Gear drive tranny repair is a bit messy but not that difficult;t. There are sweveral videos here in the Instructional videos transmission section.

I'll take a look over it and see if it's something I'm capable of doing.  I am kind of handy when it comes to stuff, but this is a step I've never tried.

Thank you all for the help!  It is more than appreciated!

Not that hard of a job. I had a diff. bolt break several years ago in my 1989 414-8 and having never had the tranny apart but owning Wheel Horse tractors for over 50 years I completed the tear down and repair. while apart installed all new bearings and seals, with the help of many more knowledgeable members hear. Ordered parts hear from our vendors. Don't underestimate what you can do, especially with some help. Bob

I appreciate your confidence in me!  My main problem is I have limited space. If I were to have a shop where I could tear it down and leave parts sit for days or weeks, and be able to take my time fixing it, I'd consider giving it a go.  Unfortunately, I don't have the room really to do that. At this point I can say I'm really undecided what my step is going to be.

at this point there are many used trannys out there put a want add with all info. of you tractor and see what shows up. changing the tranny would not be as difficult as a rebuild. Just be aware that you might end up with what you already have, that is why rebuild is a better choice.
