Bearings/rust question

I am working on/trying to preserve a 1938 GMC doodlebug. The rear drums were a bear to get off but the bearings look like they were good if someone had just packed them 30 years ago. They still aren't bad but have some slight surface rust. What would you soak them in for the best results. My main focus is to make this roll and keep it from deteriorating any more then it has. The spark plugs were rusted off but I got the threads out okay and the engine is free so it may even run again.

Agreed, Timken should make a bearing to fit it. They are cheap and you should be able to find a number on the bearing and a parts store should be able to match it up. Take the old one with you when you go. Besides, also comes with a bearing race
 
I have repacked rusty boat trailer bearings and had them last, the rust will soon wear off and then it would be good to repack them with clean grease. It all depends, what do you have the most of, time or money?
 
looking at the picture,I would think that you will me driving slow speeds and not take any long trips, what do you lose by reusing them?
 
I am using them, just want to clean them up the best I can. Saving this for spare parts for my restored truck.
 
White vinegar. Soak overnight, they'll be black. Scrub that off with a brush and warm water. Dry and oil.
 

For what you he planned for it I certainly would not go to the work of replacing them. You are going to need rust converter for plenty of things soon that project. So you may as well get it over with and get it and use it.
 
Clean the rust off and pack them with grease. The pits will hold grease. I would most likely use a dermal wire wheel and rotate the rollers one at a time to get the clean to the depth of the pits. It might take a few dermal wire wheels and a bit of time.

Dick,

I'll bet that you mean "Dremel Tool"
 
I would wash them out in good old soap and hot water followed by a rinse in a solvent to displace the water.

Rust dust will get flushed out better with water assuming the bearing is as grease free as it looks.


Not like you will be rolling along at highway speed anytime soon.

Had to move a boat and trailer 300 miles, checked the bearings before I started out, they were bone dry and badly pitted.

Nearest place I could buy bearings on the weekend was an hour away.

Rinsed them out with a garden hose, banged them against the bumper a few times, poured some diesel on them, shook them off and packed them in grease.

Started off slow and checked them for heat multiple times, by the time I reached town 50 miles later at highway speed they were spinning smooth and not heating.
Took a chance and kept going, 5 hours later they still fine.
