that was bent when the damage occurred.
Where the left hand piston
rod (removed) would enter the cylinder.
The big end strap was
forced apart leaving the bearing a loose sliding fit when it
should be secure.
Big end bearing showing
the damage to the white metal when the crank journal "hit"
the hydraulically locked piston and connecting rod assembly.
A shot taken when the
engine was stripped down at Crewe, the arrow shows where the
big end bearing runs on the crank journal. 16/08/03.
