If you ignore the artistic soft focus, you should be able to make out the slot in the pin now the pin is back in the hinge. I tightened the machine screws to the required 10 Nm, but didn't thread-lock them as I would rather this was just something I keep an eye on and check during servicing. Besides, I have other plans for stopping the screws from winding their way out of the pin (they should only do this if the bike is folded and unfolded, but I don't often need to do that).
