I was lucky enough to attend a talk by Graham Robson, & he mentioned that the
factory
managed to break a crank once & it was attributed to harmonic vibration &
subsequent
failure; Robson felt that that considering the amount of testing done this was
an unlikely cause. Well, I paraphrase what I recall he said, but that was about
it.
I have read of TR cranks breaking, but at low revs & low load, which is rather
strange.
However, if you remove the fan/harmonic balancer & your crank breaks at 8000rpm
as you out-drag that MGB, I've never heard of you ...
