It was a known problem in the first batch and that was the only time they used this technique. You can try to contact your LHS or the Serpent distributor for a free replacement (I know they did in the past.)

If you know someone with a welding machine you can weld a small tip on the shaft side of the crankshaft and finish it with a dremel to tighten the pin. I know a person who did and it worked for him.

But this is the one you need:

Directly after the bad productionseries they made a one-piece crankshaft so this one should be a fixed one.
