Well lets see.
1. Crank bolt too tight. Ambitious repair person uses 20' breaker bar to get loose and snaps off bolt in crank.
2. Repair person has terrible day, angry at the girlfriend/wife/boyfriend/husband, full of rage and aggressively pulls off the harmonic balancer neglecting the reluctor vanes on the back side and bends one really good. Attempts to repair and snaps off.
3. Repair person determines that he/she doesnt have the right bolt for the puller and decides to 'modify' the threads by drilling and tapping new threads. In the process the drill goes through suddenly and drills through one of the reluctor vanes and then hits wiring behind balancer chewing up the wiring harness to the cam shaft sensor.
4. Repair person remembers trick of placing breaker bar on the bolt and trying to 'bump' the starter but doesnt know which way the pulley spins and takes a 'whack' at it since they are feeling lucky and have a 50/50 shot. They guess wrong, breaker bar swings around crashing through everything.
5. Repair person has trouble getting crank bolt out and decides to use a little heat, sets engine bay on fire.
