    This Big Twin might have had its flywheel grabbed on the outside instead of using the devoted holes for pulling. Has anyone ever tightened a puller so much it pulled the flywheel right off the hub? Doing this would ruin your day and open a big can of worms! 😥

    OMC made a change in their Big Twin flywheels around 1958-ish. The revised hub has a flange that the puller screws into. The one in the picture is the old style where the flywheel could be pulled off of the hub. Worse, they often broke loose.
