Main function

The piston pin for Scheppach and Woodster 51.7 cm³ garden tools and brush cutters – Ref. 3904803006 is designed to connect the piston to the connecting rod of the petrol engine.

It allows the piston to pivot freely in relation to the connecting rod while transmitting the mechanical forces generated during the different phases of engine operation.

Subjected to high loads and repeated high-speed movements, a piston pin in good condition is essential to ensure the proper operation of the piston/connecting rod assembly and the reliability of the engine.
