2.2.15.15. Check of the block of cylinders

Fig. 2.159. Measurement of degree of a buckling of a surface of the block of cylinders

Measure degree of a buckling of a surface of the block of cylinders in six directions, as shown in the figure 2.159.

If deformation exceeds a maximum, replace the block of cylinders.

Maximum deformation of the block of cylinders: 0,10 mm

Fig. 2.160. Scheme of measurement of diameters of cylinders

Measure diameters of cylinders in the X and Y directions at distance of 42 mm from the top surface (fig. 2.160).

If diameter of the cylinder exceeds a wear limit, replace the block of cylinders.

Standard limit of diameter of L8:

83,000–83,030 mm;

LF, L3, L3 (with the mechanism of change of phases of gas distribution):

87,500–87,530 mm;

Minimum / maximum diameter of the L8 cylinder:

82,940–83,090 mm;

LF, L3, L3 (with the mechanism of change of phases of gas distribution):

87,440–87,590 mm.
