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
A piston pin is a hollow shaft that connects the small end of the connecting rod to the piston The skirt of a piston is the portion of the piston closest to the crankshaft that helps align the piston as it moves in the cylinder bore Some skirts have profiles cut into them to reduce piston mass and to provide clearance for the rotating
