Took the pulley off of cooling fan to blast and repaint. Just noticed when blasting that there is a small piece of metal pounded into the pulley. Did the factory do this for balancing? If so, did i screw up by not indexing fan and pulley prior to removal? Thanks for your input.

Yes. Plus the pulley will no longer be centered to the fan hub.

Re-centering will be a real bitch.. Unless you have access to a balancer or make yourself a centering tool, it won't be happenning. This is critical to dynamic balance and even keeping the alternator belt on the engine.

Both.. If its not centered it can't be balanced. I have seen people remove these and reinstall them only to imbalance the engine 40 grams.
