That should be an easy test - what's the frequency of the clicking? That should actually narrow it down quite a bit. The first stage gear reduction is going to have the highest frequency of clicking if that's where it's occurring, and the chain will have the lowest. Simply knowing how fast the motors are spinning and the frequency of the clicking should bring the investigation down to a certain gear or bearing almost immediately.
