Cleaning Gunk From Bearings: What To Use ?

Oct 04, 2015 9 Replies

Hello,



Trying to get the gunk and dried up grease out of motor bearings. Unit is eons old, and armature won't turn easily anymore.



Tried Liquid Wrench, and also soaking in gasoline.



Neither seems to dissolve the stuff.



Anything better ?



Thanks, Bob


I assume you mean a ball bearing...if sealed, pop the seals off and soak in fuel oil, brush, and blow-out the bear. Don't spin it dry with air! Re-pack and replace the seals.

Is the race actually *visible*? Many bearings are *sealed*.

Consider simply replacing the bearing? (what's it in?)

Try using a detergent solution soak . Grease is oil and soap , if all the oil is gone you're left with the hard chunks of soap that it was emulsified with . You might try using an ultrasonic cleaner , but on low power . Some believe the ultrasonic waves cause damage to the bearing elements and races . I don't know , I have no experience with ultrasonic units .

Hi,

Thanks for help. What a terrific Group.

Ditto, for all the trouble cleaning it and not a guarantee it'll last. I'd just get new set of bearigs.

Do a search for Ed's Red. It is a gun cleaning mix of something like kerosene, auto transmission fluid, varsal, and acetone.

Just an equal mix of kerosene and ATF usually works well for clening.

Well, gasoline should ought have done the job.

I've also used spray can brake cleaner from the auto parts store. Kerosene or diesel fuel are hydrocarbon, but don't evaporate as fast as gasoline. Small chance that acetone (nail polish remover) might work.
