Hello, everyone and thank you in advance. I got bit by the bug a few months ago and bought a 1974 b 80  the rod broke, about a month after i bought it. So to keep my 4yr old mowing i picked up a c120 auto and i was going to change rear wheel seals pulled the hub to find the axle moves up and down and side to side about an 1/8"  what's involved in put in new bearing and does it need to be done now or a winter project. Thanks  

 

 

 

         PS sorry about the grammar

I would not wait personally. The longer it runs the more damage can be done, and if these particles go through the pump/motor, then it can get expensive and require facing or replacement of VERY expensive parts. Hopefully the strainer is ok and the broken needles are still in the axle housing.

I'm pretty sure you have a 90-1136 hydro. This one should cover it. :)

Sorry no pics yet, definitely in need of a new 1 new hub. The side with bad bearings has good hub the other side has good bearings, but  the hub key way is all buggered up. Someone has opened up the transaxle before. Where is a good place to find a hub.

To find the axle bearings you need to look at the parts list for the tractor model you have. The transaxle has it's own page and there will be two different part numbers listed. One for the 1" diameter axles and one for 1-1/8" diameter axles. These are not the best parts lists as they fail to identify what model uses what bearings. We may have original parts lists that will be more easily understood.

Update, bought 1 hydro rear, and a 1969 electro 12 with no pto  and has 16hp Kohler on it. Hydro trans and lift might swap on to c120. Any idea how to fix a buggered up key way on a axle?

I did something similar to the link above, got a piece of copper the correct thickness matched the radius of key to one of my hole saws and

cut a piece out Put a flat on it so i could clamp it in place and welded around it. Came out pretty good.

I just went thru all this on my C160 about 2 months ago. Let me know what you need to know. Looks like you need 2 new axels. That much play in the bearing means the axel is also chewed up. Those axels are also induction hardened, but only in the bearing area. Finding good axles takes awhile. I pulled my transaxle apart. I got 2 great hubs from A-Z parts. The local machine shop wanted $175 each to fix my keyways. Newer axles have a bigger woodruff key to stop this from happening. I found 2 used axles.

After i do the swap, i will open up the old rear end and see what i need. I bought a parts hydro so hopefully i can make one good one. Searcher60  Thanks for the advice I'm sure i will have questions once i get started. You wouldn't happen to have any pics of the inside of the rear?

Be careful, as there are like four different pump/transaxles. There are differences inside.

Good luck! I gotta say, I think you mite should just bite the bullet and find an axle and hub. Both my axles and hubs were tore all to hell. Cost me about $300 in used parts to get it straight. The correct used axles in good condition are hard to find. The machine shop wants just as much as new axles cost to fix those.

      Hi folks:
      The wheel bearings in one of the front wheels of my 416-8 imploded the other day while mowing. 32 years old, I'm not complaining. Anyway, with the advice of another thread I picked up a set of 4 flanged bearings off an ebay seller. . .3/4" ID, 1 3/8" OD. Problem is they are a loose fit in the wheel hub. I should need to tap them in, but they just slide in and out. No real play, but they can just fall out. The insides of the hubs are clearly worn.  Any advice on snugging up the bearings"
       
      Thanks,
      J

      I have what I believe is a Wheelhorse transmission from a 1964 -1966.  Is this worth selling via shipping?  I'm not sure on the value or desire for these parts, as I don't know if it is worth it to post online or just sell local, as I imagine that the shipping cost will be quite high because of its weight.  What do you all think?

      Just picked up a 312 8 Tractor, Shifter handle is very loose and it won't go into none of the gears. Any ideas? Fixes?

      Hello,
       
      I have what I believe is a 1989 312-8 wheel horse and need to purchase transaxle dipstick.  I do not need the tube just the dipstick, however, if the dipstick comes with the tube that's fine also...
