nup, never done it, never had a flywheel come off.
if you're running big numbers and big revs, you probably have a big wallet too, so in that case i would probably do it.
buzzzz sorry charles you fail at life!
The bolts should be replaced every time due to them being stretch bolts. Once the thread has been stretched they become unusable due to them not being ableto hold tourqe any more.
In saying that lol i never replace them.
They are not a torque to yield bolt. Replacemet is not necessary! Maybe behind something with 900hp you would replace them but otherwise not necessary!
