The gudgeon pin or wrist pin (as it is called in the US), connects the piston to the connecting rod and provides a bearing for the connecting rod to pivot upon as the piston moves.
Gudgeon Pin/Piston Pin
I believe a gudgeon pin is what the British call a connecting rod pin (or wrist pin or piston pin) in a reciprocating assembly, (piston, connecting rod, crank ) It connects the piston head to the connecting rod.
It is a type retaining fastener in mechanical engineering. For instance a gudgeon pin attaches a piston to a connecting rod in an engine.
A gudgeon is a small freshwater fish. A gudgeon pin is a small rod which connects the piston to the connecting rod in an internal combustion engine (often shortened to "gudgeon").
crnke shaft is the one which is attached with piston trough gudgeon pin or swift pin. Its main use is to rotate the piston in rotary motion with the help of counter weight,due to which piston resiprocate up and down.
The main function of the gudgeon pin is to connect the piston to the connecting rod in an internal combustion engine. It allows for the rotational motion of the connecting rod to be converted into the linear motion of the piston. This pin must be strong and durable, as it experiences significant forces during engine operation. Proper lubrication and fit are essential to prevent wear and ensure smooth operation.

Repairing a gudgeon pin typically involves either replacing it or addressing any damage to its surface. If the pin is worn or damaged, it’s often more effective to replace it entirely to ensure proper fit and function. If there are minor surface issues, polishing or machining the pin may help restore its integrity. Always ensure that the replacement or repaired pin meets the original specifications for optimal performance.

The Longjia LJ50QT-K scooter typically uses a gudgeon pin with a diameter of 12 mm. However, it's always best to consult the manufacturer's specifications or a repair manual for exact measurements, as variations can occur. If you're looking to replace the gudgeon pin, ensure it matches the original size for optimal performance.
