Flywheel bolts

[mark]

Just need to buy a clutch kit and then i can fit my engine into my rolling chassis permanently

Whilst working on the engine i took the flywheel off and now its time to bolt it back on.

The Haynes manual states to use new flywheel bolts as a must, is this gospel or will a good glug of loctite suffice on each bolt?


I dont have a problem with getting new bolts if required i just wondered what some of the old school mechanics opinions are first.

Thanks

Replace and torque as per manual.Its very close to your feet as it comes through the bell housing like some psycho chainsaw !

I think you will understand what I mean.

I thought that might be the reply i would get!

Replace them it is as i like the lower part of my legs

I do intend to replace my flywheel bolts as ive had them off. But why is it they need to be done?

The changing of the bolts is a safety issue on a critical application.

Basic theory is : When a bolt is tightened to the max, it will stretch a fraction.
When the bolt is removed it will stay stretched If the old bolt is then re-used it is likely to stretch again.
This in theory may result in a weaker bolt that is just within its yeild zone & in theory is more likely to fail ( Shear )

More science than that involved but that is the basic theory

I see exactly what you mean there, and if I was to unbolt a flywheel I would definitely replace the bolts with new, but my question is that if the bolt stretches, and stays stretched (in other words it's plastic) then where is the clamping force coming from? Wouldn't it want to spring back (elastic) in order for the correct amount of grip to be applied?
