Hi all,
I put together the right final today. Got new seals in there. After I got it back together, I put it on the floor to get ready to put in the main drive shaft and brake drum. It made a "clunk" sound when it was lowered to the floor. Upon inspection it seems like the hub is able to move in and out about 1/16". Now with the shims in place and the nut tight this should not be happening.

Here"s what I think.........The big bearing on the hub (#25 in manual) must not be seated up tight in it"s hole. The only thing I can see that might cause this is that bearing #22 is bottomed out on the shaft even though it has the thick shim behind it. I may have to put 1 more thin shim back there to pull the shaft another 1/16". OR should I take the thick shim out and put the thin one in there instead?

I have to keep in mind that the big bearing #25 on the hub end should be tight on the shaft. Does the bearing retainer put pressure on, and hold this bearing tight in it"s hole? Maybe the new gasket is too thick?

I"m not sure now, there is no other way to hold that bearing in it"s hole other than the retainer. The shaft and the inner bearing are definately moving together.

The is the side with the seed drive and all the parts are in just as the manual shows.

Anybody that can shed any light on this would be appreciated. I just know if I put it back on the tractor like this, there will be some clunking and side to side action felt. I checked the left side and it seems nice and tight.
 
Ed: Got the Blue Ribbon service manual in front of me. Going to try and follow your description. Bear in mind my manual is 140, should be the same.

Numbers your quoting check out. It's 45 years since I had one of these apart, and as I recall distance between bearings in the casting are what keeps it tight. Correct me if wrong but a bolt in end of axle hold this all together. That being said either washer 23, spacer 24 or bearing 22 are snagging on axle, or you've got one too many washers between the bearings. Could be washers or spacers on wrong side of bearings. Could you have left washer 27 out.

If I think of anything else, I'll come back. Just getting you to retrace your proceedure. Now, your younger than I, you shouldn't forget to install a washer or spacer, I dropped in a pail of cleaning solvent.
 
Hugh,
Thanks for the reply.
#27 is a felt washer, and it is in the retainer next to the seal. I'm really thinking it must be that the retainer is not tight to the bearing #25. There is nothing else to hold the axle in except the retainer. I think if one were to leave those bolts out the shaft would gradually work it's way out of the inner bearing and end up on the ground.
The reason I know this is because of the way you remove the axle. Remove the retainer bolts and using a pusher, you push the axle out of the inner bearing. This action will also push out the hub bearing as well. So for now this bit of play has got me stumped.
It should be noted that while the bearings are tight to the shaft, they are not tight into the casing where they slide in and out as you can move them be hand.
