2.2.15.11. Measurement of diameter of a neck of a cam-shaft
Fig. 2.154. Measurement of diameter of a neck of a cam-shaft

Measure diameters of a neck of a shaft in the X and Y directions in two points (A and B), as shown in the figure 2.154.
If values do not meet standard, replace a cam-shaft.
Standard diameter: 24,96–24,98 mm.
Minimum diameter: 24,95 mm.
