Cylinders

 PERFORMANCE ORDER

    Check up walls of cylinders about scratches, roughnesses or the ledges specifying in excessive deterioration. If a cylinder trunk very rough or strongly scratched, or with ledges, chisel the cylinder and use the piston большего the size. With the help компрессиметра measure internal diameter of the cylinder in a direction of draught and an axial direction in two positions. If you notice something from following positions, chisel the cylinder.
      Internal diameter of the cylinder falls outside the limits norms. The difference of measurements in two positions falls outside the limits a bias.
      The difference between measurements of axial section and a draught direction leaves with a deviation from “круглости”.
