Hi Mike

Looks like it is definitely your gear back lash.
Just took belt off my race car and there absolutely no back lash noticeable. Also checked those gears I pulled of rotors last week and the mesh is really tight.
I would say your problem started when the supercharger run out of oil and has worn the teeth of the gears. Also it would be a good time to replace those front rotor bearings as they are probably not in a good condition either as they are also lubricated from the oil.

Try Jon Bond maybe they can supply new gears.
Cheers mate, it is nothing you have done.
Also make sure you use the proper Anaerobic sealant when putting it back together
