APPLICATION:
Wrist pin on piston are for engines of various vehicles, JE racing, aircraft, marine, tractor.
NOTE:
Wrist pin on piston is the link between the piston and the connecting rod. Due to the oscillating motion of the piston and the interaction of gas and inertial forces, it is subjected to high loads in alternating directions. Figure 2.1 shows the piston pin load for a gasoline engine at rated power. The rotary motion of the connecting rod relative to the piston must be compensated for at the bearing locations of the wrist pin on piston, in the pin boss, and the small end bore. Due to the small relative motions, the lubrication conditions here are poor.
