That's not good. Vibration damper coming apart

Same thing that happened to mine. Like I said live and learn. I'm sure you'll be well under $100 for a new aftermarket one sent to your front door. Install and enjoy.....

If you want another issue - the fastest way to it is to cheap out on the balancer. I'd prefer an SFI approved versions that are made better and are a bit more than $100, and ATI for race engines, or the fall back of a good used factory one if the build can use it. Those are the only choices I give my customers now. I'm not a fan of the fluid balancers due to leaks.
