The piston pin is made of low-carbon alloy steel (chromium steel). The inner and outer surfaces and both ends are all carburized and quenched, the quenching depth is 0.5 + 0mm, and the piston pin has a hollow cylindrical shape. The outer diameter of the piston pin of the non-supercharged FL912 / 913 diesel engine is Φ35, and the outer diameter of the piston pin of the supercharged BFL913 / BFL913C diesel engine is 40.
The piston pin seat and the connecting rod are connected by a floating type, and are fixed at both ends with an elastic snap ring. The clearance between the piston pin and the pin seat hole on the piston is 0.003 ~ 0.015mm. During assembly, the piston pin can be pushed into the pin hole of the piston by hand without heating
