The difference between each side of the pin is:

I believe the issue is with the white metal but any suggested ways to resolve this issue would be welcome. The current suggestion is new little end bushes bored to suit the white metal
The proper way to fix it would be at the white metal end, if that's the problem.
A length of 1/2" silver steel as Terry illustrated but without the crank will prove that the little ends are fine, because if they are, the rods will sit tightly together, like bee eaters perching on a wire.
I had to get the big ends of a new set of 1.5" shell rods resized and honed because the bearing tunnels weren't round. By the time I discovered the problem I couldn't be bothered suffering the delay that a complaint and argument would probably have created.
