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 ?
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 .
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.
