Default Harmonic Balancer/Crank Pulley Slight wobble

Hey Everyone,

2008 Impreza 2.5i here. After doing some routine maintenance today, I noticed that my harmonic balancer/crank pulley (I keep hearing different things as to what it is) has a very slight wobble to it. If I rev the car a bit I can't notice it anymore. Is this normal? I tried to get a video on youtube but by upload speeds are abysmal today. Timing belt and the sort have never been done (only 45,000 miles) so I doubt the crank pulley has ever been off the car. I did try and tighten it a big but everything seemed snug.

Thanks in advance.

Normal. It isn't exactly wobble but more like inaccurate machining of the pulley edge.

I just had a chance to stop by the dealer and they concurred that it is normal operation as you said. Thanks!
