Help SD70 motor block problems


help !

the front wheel of TWO different SD70s have frozen.
there are two things that may or may not be contributing factors .
one is the fact that i painted them but it took care to mask the axels.
second is the added weight ( about 15 lbs total)

if anyone has seen this and knows about this, I would be grateful



one is brand new

Exploratory surgery?
I suppose it’s a driven axle, correct?
Could it be a reaction of the plastic to the solvent of the spray?

definitely surgery

some good resources out there
