Pro 600 makes a clicking noise after repair and regrease

The planetary hub was falling off while using the flour mill. I watched some videos and learned how to disassemble and reassemble it. Instead of replacing the hub, I used JB Weld to reattach the shaft. I cleaned everything very well, greased all the gears according to instructions, and packed the case with new Superlube food grade grease. Now it makes a clicking noise that it never did before. It's frequency matches the speed, and it sounds like it is coming from the motor end of the transmission. Any ideas about what would cause that? The only thing I have found in researching it is the possibility of too much grease in the case, but other videos have said to pack it pretty full.
