Transmission Rebuild for spare

[Dale Finch]

With all this time on my hands, and having finished up on one of my tractors' servicing, I decided to rebuild a spare transmission I have had for several years. I hadn't done one before, so it was to be a learning experience! I was going to wait until I was finished, so it would be more concise, but there is already a good HOW TO on transmission rebuilds, so I will simply post as I go and get answers to my questions.

First thing I did, when removing the Differential Seal Retainers, since the shims (the number and thickness) are specific to each individual retainer, was mark the two retainers. I decided to make punch marks, since any ink-type marker would be removed during cleaning. Here are the results:

Two marks on right retainer with corresponding marks on housing, near the bolt hole that points forward. This makes orientation & reassembly easier, since those 3 holes only go one way.

Two marks on the right:

Three marks on the left.

When removing the countershaft, I noticed the race for the countershaft rear bearing was a separate piece:

When checking the parts manual, it looks like that is the case. Can someone confirm that? Also, TM Tractors does have that bearing (and it does seem to include an inner race), but $93.70???

Anyone have a less expensive source? Otherwise, I may just reuse it, if I can confirm it is OK.

I just want to make sure this transmission will be flawless, if/when needed. Thanks for the input!

I already have a replacement Transmission Shaft Rear Needle Bearing. But in the bottom of the housing were not only the loose pieces from that, but a few other pieces that I hope to identify. I have already looked everything over (I THINK!), and cannot find what these pieces would go to. Any help would be appreciated!

These two pieces are shown with the needle bearing for size reference:

Hi Dale,
It looks like you are having a grand time in isolation.
Having just done the transmission on my number cub, I can offer the following:
The rear two piece bearing is a "NU-206" and can be purchased for way less - I paid about $20 for mine and was very satisfied with the quality.
For the rear needle bearing - the original has an oil hole that aligns with the rear oil hole coming down from the top in the housing. I found BH-1312-OH to be that bearing but just a tad wider - plenty of room for it. They are no longer available from IH but I found a couple after an extensive search. The second is a spare and yours if you want it.
No idea what the "slug" is.

While strolling through online, I found one that looked pretty good, $38.41. Then I looked at shipping...$52.04!!! Sheesh! That thing weighs about 1/2 pound at most, and would fit in an $8 flat rate box!!! WTF!

The markings on the end of the slug make me think it is a dowel pin that was inserted too far and rubbed/mashed over time. But from where? Hmmm....

Hi Ron! The one you have has the oil hole? Want to trade?!

[Dale Finch]

I was taking more photos of one of the metal pieces, and when I turned it over, I may have realized what it might be. See if you concur...give me YOUR best guess!!

This is the one that convinced me (sort of!!) as to what it WAS. This is the BACK side...

Now the question is: HOW did it get in the transmission?!

[Urbish]

The markings on the end of the slug make me think it is a dowel pin that was inserted too far and rubbed/mashed over time. But from where? Hmmm....

Maybe it is a nugget that was poorly welded onto the end of a shifter handle long ago?

[Urbish]

It is smaller than I realized. Is it a rivet from a pair of jeans/overalls?

[Dale Finch]

I'll wait a bit before I tell you what I THINK it is...!

[Bob McCarty]

A zerk fitting gone bad?

The pin that keeps the shift lever from turning.

You looking for the same bearing he is?

Yes, that's the one. I did find this one:

Think this is the correct one? I still need to see if mine is good, but if there is ANY doubt, I'll replace it, and this looks a whole lot better than $93.70.

That is exactly what I think it is! The back side has a hole in it, and when I looked back at the front, I realized that the dot is actually the ball valve. How do you s'pose it got in there?!

Anyway, that only leaves those thick curved pieces to identify. I just don't want to put it back together IF there is still something broken inside that I didn't see.

[Urbish]

The thick curved pieces don't look like anything I have seen in the transmissions I have worked on.
