flywheel to crank

[Falcon67]

One bolt is offset.  It only installs one way.  You just keep rotating until they line up. 
Seems like it takes me about three rotations before I find the right way because I never believe I got it right on the first try.
Then I need to verify it....

Why I use a Sharpie on disassembly LOL.  I've also used paint daubs.  Never hurts to save a minute here and there.

[Gregwill16]

Yeah it seems to always be the last turn you try...

I'm glad to see that others have picked up on the marking of the flywheel to ease reassembly.  As stated without the marking or exceptional eyesight the chances of hitting the pattern the first time is a crap shoot.  Using a sharp edged ring gear to lift or even turn a heavy piece of steel more than once is at the bottom of the list of weight lifting.

The same designer that made USB ports made Ford flywheels.

LOL!!! Why is it that 99.9% of the time, you get it wrong on the first try? Not even Murphy's Law has odds like that.

Technically speaking, it has to be that way for the external balance engines. You don't want the weight to end up in the wrong place.

I remember from my days in the Navy we used to say 50/50 90/10, 50/50 chance of getting it right 90/10 probability of getting it wrong.
