There is no bolt!
Just a lot of emptiness! I wanted to turn the engine over with a wrench, but I have a void where I think a bolt should be.
Not sure if it's threaded in the crank or what.
I'll get back to it wed night.
What do you not understand what was said above? There is no crank bolt as you know, but there is a threaded hole there for one.
The damper is NOT SCREWED on!! It is a press fit. Just go to O'Reilly's or someplace like that and use their "borrow a tool" program and get a Damper/gear puller, your not working on a rocket.
