The symptoms of a 3 bearing crank failure?
#24
Those are spectacular failures Terry!

This rod was in the ‘26 Heavy 12/4 - we were returning to Bristol after a long weekend in Lake District.  As we passed Gloucester on the M5, doing about 45/50mph, there was an almighty bang and tremendous vibration.  My father pulled over and eventually we were relayed the last 25 miles home.

On stripping there was no sign of the piston - just thousands of tiny aluminium pieces.

The rod was in the sump and the engine still ran.  This rod is about twice the size of an A7 one.

   

   

   

I always thought it would make a good novelty toolbox handle...
