Crank bolt was not used often, maybe only on trucks and a fe car motors....? many didnt have it. Chain should show less than 1/4" deflection but your in there, may as well change it as they are pretty cheap.
Yeah, that is not what I have on the chain. Looking at the engine one side is tight and the other side probably has 1" slack. I thought maybe 1/2" max would be ok but not 1".what do I do about the crank pulley. drive it on with a socket. what keeps it on the end of the crank. seems kind dangerous to me.
