Years ago I had AM planetaries bind after assembly due to excessive slop in the backplate holes for the bolts that join the backplate to the housing. Since having been totally redesigned, I'm assuming this issue has been resolved with a slight locating "boss" or something?

In general, for any gearbox in an FRC application, if I was experiencing binding due to small burrs, slightly close gear fitment, or other "light" (non-serious-flaw) issues, I would go to the auto parts store, purchase a bottle of Rubbing Compound, squirt in a judicious amount, and run it until I watched current draw fall. (I have done this by the way and it works). Then clean it out and grease it up! Just try to keep the compound out of bearings.
