[R-390] Ultrasonic cleaning

[Bob Camp]

HI

The problem with the split gears is not damage in an ultrasonic. The problem is that the dirt is way down in-between two parallel plates. There is pretty much no way to get it out of there.  There’s kind of a 50/50 chance you will push it deeper rather than remove it.
