it does not come out at TDC. it only comes out when the red tooth is lined up with the pointer. same going back it. it is not a timing mark, but a removal mark. you need to go read how it goes. not trying to be 'mean', but this is something you need to read and understand before doing it. there are probably hundreds of threads here now about how to do it right and the consequences of doing it wrong. if the drive gear was already like it is in the picture, someone before you did it wrong as well, so setting the timing now will be a challenge.
