Even if insignificant deterioration of the block of cylinders is found out, cylinders are subject obligatory хоннингованию. The block of cylinders of an incomplete complete set The block of cylinders of an incomplete complete set contains the block of cylinders with established krivoshipno-shatunnym the mechanism and piston group.
