The connecting rod in the M40 acts is the link between the reciprocating motion of the piston and the rotational motion of the crankshaft. Crafted from cast aluminum, this component facilitates the transfer of energy from the piston to the crankshaft during engine operation. Brass bushings are incorporated at each end of the connecting rod, serving as bearings that reduce friction and wear. The design and construction of the connecting rod allow it to withstand dynamic forces and high speeds, ensuring reliable engine performance. As the piston moves within the cylinder, the connecting rod efficiently transmits motion, contributing to the seamless operation of the engine.
