It kind of screws up the puller bolt plan.<br /><br />I used to use a couple of the ring-gear bolts and a peice of flat-bar similar to how Upinsmoke describes. Well, actually an old lawn-mower blade. Then I made the 'Worlds Largest Strap Wrench' as a 'learn how to weld' project. It's uglier than sin but it works fine on Big Twin flywheels.<br /><br />I have also sucessfully torqued big twin flywheel nuts by jamming the starter's bendix with a peice of plastic/brass/aluminium. But I was prepared to repair the starter if I broke it. <br /><br />Well, I guess I'm just saying there's lots of ways to skin that particular cat. All without using the right tool.
