This article presents a method for calculating the connecting rod piston head, with the aim of predicting a reduction in its failure and premature failure. Analysis of the operation of internal combustion engines in automotive and tractor vehicles shows that engines undergoing major overhauls are primarily due to accidental damage to key components. Connecting rod technical condition accounts for 30% of engine overhauls and 35% of re-overhauls. The majority of connecting rod defects occur in the upper end. Connecting rods operate under dynamic loads with a dynamic coefficient of 1.15-1.22, which must be taken into account when making changes to their design and technical condition during operation.

Keywords: connecting rod, load-bearing forces and moments, stress, sealing angle, safety factor.
