Piston Pin Assembly

The piston is attached to the connecting rod through a hollow, hardened steel tube known as the wrist pin or gudgeon pin. This pin passes through the small end of the connecting rod and allows it to pivot on the piston.
There are two methods of securing the wrist pin. A semi-floating arrangement has the pin fixed into the connecting rod, while free to rotate in the holes in the piston. A fully-floating wrist pin will be free to rotate in both the small end and the piston and will be secured in place using circlips, or Teflon buttons in the ends of the pin. For a fully-floating wrist pin, there will be replaceable bushing inside the small end hole. The wrist pin may be slightly offset laterally rather than exactly centered on the piston. This is known as an offset wrist pin and is used to cut down on the side-to-side movement of the piston within the cylinder.
