Mech fan hitting harmonic balancer

New random issue. Mechanical fan is hitting the harmonic balancer pulley, or whatever that big pulley at the bottom is.

Swapped the fan clutch for a napa one about 3 weeks ago and it was fine till today. I checked the nuts to make sure they hadn't come loose and they are tight. Belt looks aligned so I don't think anything became misaligned. Any ideas?

Thanks!
