We haven't run into this issue in any of our Versaplanetaries, but it might be because we use them in light applications for fear of overloading them.
Whoops, looks like I accidentally deleted that info from my original post. I don't have a picture at the moment, but it's for a flywheel style shooter. We're using a single stage 3:1 drivenby a 775Pro. This feeds into a 1:1.2 gearbox, for an overall reduction of 2:5:1 driving a 4" wheel. We see about 10A of current draw at 7k RPM at the flywheel, which is right in line with what we'd expect from the spec sheet, suggesting we don't have any sources of unexpected load.

It seems like it may be a good idea to press the pins back in and add some red Loctite. No access to a welder, unfortunately, so that's not going to be a possible solution for us.
