car UAZ-3151

Repair of connecting rods comes down to replacing the upper head bushing and then processing it to fit a piston pin of a nominal size or to processing the bushing available in the connecting rod for a repair-size pin

Transmission of torque to the drive axles is carried out by open-type cardan shafts (Fig. 1), each of which has a movable spline connection and two cardan joints

The durability of a repaired engine largely depends on its running-in on a stand and the operating mode of the car during the first 1000 km
