Mains bolts - new or old?

[AlexG40]

As title really, do the bolts for the mains bearings need to be renewed during a rebuild?

I would as a matter of course, usually torqued once for machining, and once more at factory for installation, so a new set won't do any harm (they're not expensive either).

Sweet shit. Cheers Yoof.
