RE: HBK2 ?
I don't have a CP2, But i'm pretty sure you warped a Feathering Shaft or the Main Shaft and even highly possible that you warped em both.
It's pretty easy to fix either way. You need to remove the feathering shaft and roll it on a flat surface, same as with the main shaft, sometimes a bent main shaft is visible without taking it apart if it's bent bad enough.
