- In a crosshead engine the gudgeon pin connects the piston directly to the connecting rod and carries the entire load.
- The gudgeon pin is usually offset from the centerline of the piston to allow for the connecting rod to be positioned at an angle.
- The gudgeon pin is typically retained in the piston by circlips or snap rings to prevent it from coming loose during operation.
- In some engine designs the gudgeon pin is also known as a wrist pin or piston pin and serves the same function.
