hello guys! 
Sorry for the delay in responding to you all!
Once again thank you for your attention ..
I have not got time to continue with my work in the locomotive ...
But when I have time to return to work, I'll pay attention to all comments and suggestions posted here ...
Hugs to all! 
Gilberto!
The splines are pressed last, on frame.
Do you mean that they create the splines on the center of the axle after it is already inserted into the frame?
If so, wouldn't the gear be in the way?

In my "Shell" printed the number 736!
But as I bought used, I think this locomotive may have suffered "mutations".
I had to remove the wheels because they were "stuck" with some kind of glue to remain fixed to the axes ...
The damage here is great ...
Yes I also think I will have to replace the bushings on all wheels and I bought these M 671-19 as I saw in Greenberg's Repair Operating Manual for Lionel Trains 1945 -1969 ...
This is my first restoration, I have a lot to learn yet, and especially with the right tools to use ... For here in Brazil I will not find a Lionel pulley puller, I had to adapt one and it worked ... but great care is needed!
I learn
Thank you for listening to all of you !!!
And sorry my English!

I think you're right about "mutations" I have never seen, nor heard of, a 736 with Baldwin disk drivers only spoked drivers were used on the 736. It should also have the magnets for Magnetraction if it's a 736 or at lest a place that mounts them on the frame. The Baldwin disks were used on the 726 which didn't have Magnetraction nor a place to mount magnets, in the frame. So the question is do you have a 736 with 726 drivers or a 726 frame and drivers with a 736 boiler?

It's a 1947-1949 726 chassis. The spot for the magnet would be visible in the pictures from the first post.
Im pretty sure there is an old (b&w) documentary video that covers that quickly (like two seconds); Marx, Lionel? No telling, I watch the Euro videos too....And I was told as a kid, an original steam bearing lasted longer than a replacement from not having to be pressed over the raised splines...???? I was also sent on snipe hunts at, so you never can tell 
My grandfather had blank axles, and I know he had a spline, press similar to a pipe flairing block press. It came in handy on resetting some loose Marx wheels though the pattern was off. He had arbors for the flat pressed onto car axles too. Bought or made?; its tough to say.
The 622 geared wheel and axle, the early magnetic axle, came as a replacement part from Lionel with the bearing on the axle between the wheel and the swaging. The axle would have been pressed into the gear at the same time the bearing was being pressed into the truck frame. I have not seen this done on parts for any other locos.

I have a bunch of wheel / axle assemblies, purchased from Madison Hardware (Detroit) in a wheel grab bag, that are new old stock. None of them have the bearings.
The wheel sets for a 1946 Berkshire are found as an assembly, with the wheels, axle, and both bearings. I have a few of those too.
Madison Hardware Detroit? You know I thought there was one here at one time. But with all the mention of the shop over the years, I thought it was an east coast thing.

When Madison Hardware was owned and run by Lou Shur and his brother Carl, it was in New York City. Lou sold the business to Richard Kughn, who relocated it to Detroit. Often when I mention Madison Hardware, I will put (NYC) or (Detroit) after it because to me there is a difference.
While the business was in Detroit, they would periodically issue sale flyers. I purchased some stuff from those flyers, including wheels and armatures by the pound. The quality of those parts varied. Some were nice, NOS parts, others were usable seconds, and some were just garbage. Overall, I was happy with what I purchased.
The Berkshire wheels I mentioned above did not come from Madison. I picked them up when I was focused on 1946 Berkshires.
get a bigger hammer!!! and Im NOT kidding. this came right from my parts guy, Jeff Kane of
ttender.com
hold the locomotive in your lap in a pile of towels for cushioning. take a nail set slightly smaller
than the diameter of axle. place on the axle and wrap it with the hammer. wheels will pop right off.
you will then need to keep pounding the axle thru the body to dislodge the gear. Ive done this and it works everytime.
no wheel puller needed.
