Interesting, so that is a side effect of unsealed bearings?
I could see how pressurizing the gearbox could avoid this, but first report I have read of this... was the loco left outside for a long time? Basically all I can figure was heating and cooling allowed the cooling gearbox to draw moisture with attendant grit into the gearbox.
What are your theories?
