Notice fluid side/air side. Might have to click on 2nd image to see it. https://mechanidrive.com/25x40x7tc-tcm-oil-grease-seal/

I was afraid of that. Any suggestions on making it easier for the spindle to fit into the seal? Will a little grease hurt?

Grease will not hurt anything. You can also poke a socket that is roughly the same size or slightly larger than the shaft down from the top and then push the spindle up from the bottom. The socket will help hold that seal open.

Just wanted to let you know what I did to get the spindle to fit into the seal. Actually, I trimmed a business card down lengthwise just enough so it could completely wrap around the diameter of the spindle. I slid the rolled card into the seal and pushed it almost flush to the top of the seal. I then slid the spindle into the inside of the card and push the spindle and card up until the bearing on the spindle seated in the bore of the bevel case. The card then slid out of the seal with ease. This was actually almost too easy.
BUT, now I have another issue with both of my spindles. The keyways are not machined parallel to the center line of the spindles. So, this means the steering arms will not assemble to the spindles. I've discussed with Braden and he has an email with pics of the spindles keyways.

I can't really tell by the pictures you sent so it must not be much out of parallel. Have you tried to install the steering arms? Ive never heard of that before and we have sold a bunch of them. I only have a few of those spindles left and Braden is going to see what he can find. Those few are the last in captivity and then they are gone. If it were me, and it was not much out of parallel, I would probably just file the steering arm side of the key to make it straight. Judging by the pictures it would not take much. That is sort of the fun of any of that aftermarket (and some OE) stuff. No matter what I'm working on from a Kubota to a hotrod- virtually NONE of that stuff ever just falls together. It seems like you always have to improvise.

There is a little bit of optical illusion going on there because of the fish-eye effect but can't really see anything much out of parallel.

Please review the attached pics. I have the means and ability to check the parallelism of the key to the spindle.
On spindle "A", on the flat surface of the key before getting to the radius on the ends, I am getting .030" difference in about a 9/16" distance. I don't know about you, but to me that is a lot, almost 1/32".
On spindle "B", I'm getting .012", almost 1/64". Not as bad as spindle "A", but in my book, that is bad.
If I had a milling machine, I could fix the keyways and make special keys to fit. But, I don't. (really wish I did)
Neither of the steering arms will fit on the spindles with the keys installed. I might not have such an issue filling the key for spindle "B", but that is just way too much for spindle "A".
Since you have mentioned that spindles are few now, I believe I will reverse engineer the spindle so I can get it made locally in the future if such need should arise.

I'm not sure that I have a good way to check parallelism that close. I'm going to be out of the office the remainder of this week but I will see if we can rig up something to test the rest of the spindles that I have and see if we have any that are closer than that.

Never mind. I'm going to travel 2 cities west of me to someone's place that will let me use their milling machine. I will correct the keyways and make special keys to fit the spindles and steering arms.
I don't like having to do this, but as I mentioned earlier, I really need to get my tractor going again.

Got the spindles corrected and made new keys. Now, dang it, If I can just get the time to reassemble.
I did also make a drawing of the spindle in case I need it in the future.
