Replacing Flywheel Bolts
« on: 25.11. 2017 12:53 »
After cleaning the sludge trap, do I need to fit a new flywheel bolt (the one that retains the trap)? Presumably I don't need to change the other two bolts, which I have not removed? Or do I really need to change all three?

Thanks - Rowan

My A10 sheared a flywheel bolt which wrecked the crankcase.

Very expensive.

Dont risk it replace the old set with a new high tensile set.

That sounds a convincing enough argument! I will add the bolts to my SRM order!

I agree with JulianS but in saying that I have never had one let go. Had all 3 out numerous times and torque back down to 30 Lb and red Loctite. It might bite me in the idiot one day.
