Dewalt from the 50's?

Bought a Dewalt radial saw from CL .Want to restore it the best that I can. Well it sounds like it needs bearings so I need to remove the motor covers. It appears that something sharp needs to be wedged between the cover and the motor housing. I think the bearings are in the cover. Does anyone know the professional way to remove the covers to access the bearings?

If you mean the carriage bearings you would remove the cap on the front of the arm and it would just pull out the front. Not sure where you would go for new bearings though.

I've got a 16" Dewalt that was used during WWII. Bought it 5 years ago, restored it and never been able to use it because I don't have a place to set it up. Needs to be restored again. Mine is three phase.

Once you get that saw fixed, you will love it. I had a 16 inch one made in 1957 and it is still running great. Sorry I am no help with your problem.

Anything is possible IF you don't know what you are talking about.

Look at the 5th picture in the link you posted with the two arm puller. You probably need a gear puller to ease that end off of the motor. Maybe 3 arm gear puller to apply more even pressure around it. Just be very careful as to not damage the motor.

Find the numbers of the bearings, usually marked on the sides of them. Then find a bearing/power transmission store near you. They will be listed in the phone book Yellow Pages. You can also search for the bearing numbers on Google. They will pop up many sources, but I usually get better bearings than the originals when I talk to the guy at the bearing store. DeWalt didn't make your bearings, they bought them from a bearing manufacturer, likely the cheapest that they could get in large quantities to build your model saw. The name DeWalt is original but the Dewalt Company of today only owns the name. They have nothing to do with the original DeWalt that made your saw. If you need a bearing of any kind, go to a bearing store, or one online for what you need.

Take the motor to a motor repair shop. Have them replace the bearings for you.
The shop will use the correct replacement bearings and won't damage the motor. As far as costs, their charge will probably be break even after you buy the necessary tools. Besides, they'll know what they are doing.

1958

Off the info on the plate the saw is 3/4 HP from 1958.
Got the bell off of the fan side thought the armature would pull out of the other bell housing but maybe a little PB blaster will help that. BTW Fafner bearin on the fan side.
Really was quite easy to loosen the covers once the flat was exposed after turning the cover.

I didn't want to put any pressure on the windings by prying so I heated up the wired side bell . Just a small round area,and kept fingertip pressure against the motor housing and the fan/bearings. Everything loosened right up. I have not had real good luck soldering. I would like to replace the cablecoming in. Maybe I can use the hydraulic press at work to remove the bearings,and replace.
This entire product has a white speckled finish. I think this was done by a previous owner. There are parts that I can see the original green. First picture of the stator winding you can see some of that white paint. I will try my best to clean the stator so there is minimal dust.

Found a way to fix the bumpy rail bearings.
First draw off the bearing from it's bolt.
Clean as best as possible.
Grab some nitrile gloes
Grab a large globe of greaseand put it in the palm of your hand.
Pack the bearing as well as you can.the grease will get in there.Now run a boltthough the bearing and nut on the other end. Tighten slightly.
Chuck up the bearing on a hand drill and run the drill while holding the bearing . This does work.
I did this on all 4 after reading about someone who used oil and soking the bearing overnight.
