Any advice on changing the inner (alternator) belt o my 2004 lightning?

 

yup, what pulley setup do you have on the supercharger (outer)

I think you have to remove the lower pulley cage assembly.



Not sure about the idler bracket being in the way. I've swapped out the lower for a Metco hub and pulley, but didn't change my accessory belt at that time.

This guy has some good photos of the cage removal

Going to need a big azz breaker bar for the lower pulley. Heads up, it's left hand thread.
