Very Nice!
Awesome work! I wish all bearings were that easy to take apart...If so, I would have all of my bearings for my Rexair model B already cleaned and repacked. Nice pictures, too! I cannot wait to get an old Hoover.
Let's hope it works!

Bearings...
What did you soak the bearing in to clean it? And did you just pack grease into it when you put it back together?
Are you going to clean the commutator plates on the armatrue, and put new carbon brushes in it, too?
This is really very fascinating... I didn't realize that those bearings came so far apart... I will be tearing into one of mine one of these days!!

Hey Fred!
To clean bearings, use an auto part cleaner, like carb cleaner, brake cleaner...something like that. There is also a product called Chem-Dip that is used just for this kind of stuff. It has a little screen in a paint can that you put your stuff into, and then submerse it in the chemical. This will dissolve all of the old grease. When repacking, try some state-of-the-art Moly grease! It is great stuff! It never dries out, and due to the fact that it bonds to the metal, somewhat, it will last for an extremely long time. It is also very smooth. And do note: not all bearings come apart as easily as this Hoover can. The bearings on my Rexair model B are all sealed up...which I hate. I love working on my vacuums. That is one of the greatest things for me about collecting: fixing stuff! Even fountain pens are fun to fix...and write with! Good luck to 'ya!

Hi Fred,
When it comes to bearings and removing old grease, Varsol will do the job just fine. Chem-Dip IS a type of carburetor cleaner and is overkill for this type of use.

bearings
most older hoover bearings dont come a part, they must be greased with a speical hoover grease nozzle tip that ataches to a grease gun. the tip fits into the bearig and the grease workes its way into the bearing. part of the tip also comes off to grease the brush roll bearings.

Hey Chirs...
Yup, I have one of the grease gun nozzles of which you speak... Used on all of the convertibles, and 60-series machines when they went to a lower ball bearing in the motor.

yes I use it on all my old hoovers, wen I find them that is the first thing I do is cleane the fans and grease the bearings. like on the old constellations and 28s 61s convertibles ect. on the 1930's and older I have found that I need to put a layer of black tape on the nozzle tip to make it fit tighter into the bigger bearings on the older hoovers.

I'm in Hoover Heaven!
Thank you for such an INSPIRED thread, Jay. Believe it or not, I'm about to start restoration on my 750 and you've just made my life a whole lot easier! Thank you.
I've wrestled with restoring handle wiring and internal bag support springs before. I'm VERY impressed with your use of reproduction cloth covered wire. I used vinyl coated wire, figuring it was OK to go "modern" when the final product is hidden from view.
I too have become a big fan of aerosol, non-flammable electric motor and brake cleaner (the stuff that smells like dry cleaning fluid). It does a great job on gunked up bearings, carbon laden armatures and field coils. Just be sure to use it outdoors and try to keep it off of your hands.
Looking forward to the next chapters,
Marty

Wow!
Thanks for all the responses, guess I'm a little suprised. In a good way though, and I'm very glad if all this helps anyone else with their projects. Fred "compactelectra" I would be more than happy to send you the photos when I'm done, thank you for asking. About the bearings and commutator, etc. Fred, I used a very low tech solvent. Lighter fluid, the kind made for zippo lighters and handwarmers. It's cheap and works extemely well in combination with a small brass bristle brush, fine bronze wool, felt, and paper towels for cleanup. Anything left damp afterwords I let evaporate off in an open metal container, in a safe place, before disposal. I did clean the commutator plates gently with a piece of felt dampened in solvent, although they were in great shape, no wear really. I learned not to get to aggressive on those, that's why they're still discolored where the brushes touch. Also cleaned the armature shaft top and bottom with the bronze wool dampened in solvent. The brushes were in excellant condition, which was a surprise. I do have replacements though if needed later. Also, a small 1/2", stiff, cheap paint brush works great for getting all the caked on dust loosened. Oh, and of course, I almost forgot...lol a vacuum. I could use some help with one thing. The rubber handle grip is completely gone. If anyone has a picture of the handle they could share for reference that would be Great! More pics. to follow tonight, hopefully. Jay

oops, forgot
I did pack the bearings when I reassembled them using a tongue depressor and a small syringe. I used a multipurpose black high pressure bearing grease, same thing I use on my '30 Desoto. You can soak the felt pads in solvent too, and squeeze them out on a paper towel or rag. When dry, wet them with 30 weight oil. Just a few drops.

So I could do all the painting at one time, I decided to keep working on motor. I drilled out the bumper rivets on the lamp hood, and kept them so I could try to reuse them. Started polishing the hood and motor top, so there won't be to much polishing left after I paint the inside of the hood. I'll paint that and the handle at the same time so the paint can cure for a few days.

Tom, thank you so much, that will help. Not sure yet how I'll try to replicate that, but it gives me an idea. Guess I'll save that till everything else is done.

I do reuse them if they're in good shape and have a lot of length left. No chips or burn marks or anything like that.

Thank You For Sharing
the photos of your project with us. It's almost as if we were watching the progress over your shoulder!! With the attention you are giving to all the details, you are going to have one fantastic Hoover when you are finished.
And you have a 1930 DeSoto?? Hope you post some pictures of that sometime, too.
Jeff
