Cam gear coming off.
If it was pressed on, metal is distorted in the gear bore and it will lose retention on the cam. Seen this happen with too many customers.
The proper way is to heat the cam gear to about 400-500 degrees in the oven. Maybe cool the cam in the freezer. It should practically fall on or maybe need a gentile persuasion from a dead blow hammer. When it cools, it is set for life.
