Have the transmission out of my 29 Roadster and got all the parts to rebuild it. Found a wonderful video and have watched it many times, have all the parts (I think?) and getting ready to start. The one last item to resolve it the shaft bearings. Video says bearings must be "pressed off and on the shaft" - but does NOT show how. I have never done this before (famous last words....). Just watched a youtube and guy cut the old bearing off with air grinder which seems ok, but haven't found one yet that shows pressing on. Any suggestions would be greatly appreciated. Might be time to go to Harbor Freight and buy a press? If so what size should I get? Most of the time bigger is better but not sure in this case and I also have limited space in my shop (rented 10 x 20 storage space). Boy do I miss my old 24x32 garage but that is the price to pay to live in FL.......lol!

You need a press and you will need fixturing. My suggestion is take the transmission shafts and the new bearings to a local machine shop and just pay to have them replace them for you. Buying a tool that would rarely be used in a rented garage really is not prudent in my thinking.

Much to my wife's upset, I placed the shaft in the freezer and placed the bearing in the oven. I think that I waited for an hour. Quickly, I took the shaft out of the freezer and then with oven mitts I took the bearing out of the oven and it slipped on the shaft easily. I then left it alone to warm/cool to room temperature.

Make sure that you face the bearing in the correct position. You will never get it off.

My wife has since forgiven me!!!!!

as brent said you will need some help to safely get them off without ruining the baffles, shafts, etc. I put them on with a little help from an incadescent light bulb heating the bearing sitting on top of my bulb fixture and the usually slip on with ease. May sure you have your baffles oriented correctly before installing the bearings. Otherwise you will be removing again.

Be careful about youtube videos. there's lots of poor advice out there and many on brakes, etc that are not good. Let Andrews books are probably the best for mechanical and as Brent said get a machine shop locally to help you put the bearings on. I would think they understand the process and can do it for you fairly easily.

The attached document shows a number of photos of a transmission seminar held some time last year. The Model A transmission is fairly simple, even a child can put one together...almost!

I was a little older when I did my first one, think I was 16.

ive just used an arbor press. its been sitting in oil so its got plenty of lube. didnt think much of it in terms of how hard. The rest of the rebuild is paying close attention to little things like baffle orientation, if your splined shaft nose has a ring or not, remembering to put the bearing spacer inside the cluster and which short or long bearing goes where.
