RECONDITIONING OF CONNECTING ROD CAPs
In the event of ovality, the connecting rod is processed on a honing machine for connecting rod caps produced by the American company Sunnen. The connecting rod cap is machined to the required catalogue dimensions with the perpendicularity of the bore to the connecting rod shaft.
RECONDITIONING OF CONNECTING ROD END
The large clearance between the pin and the bushing in the connecting rod end is eliminated by replacing the bushing and its turning. The use of a Sunnen boring machine for connecting rods allows us to obtain the adequate clearance between the bushing and the piston pin, maintaining the perpendicularity of the connecting rod and the identical length of the connecting rod set.
BALANCING CONNECTING RODS
A very important connecting rod parameter is its mass. The set of connecting rods should fit into one weight selection group. Weighing the caps and ends’ mass of the connecting rods is performed using an instrument along with precise scales. Possible differences in the connecting rod masses are eliminated by removing excess material.
