2.2.15.20. Measurement of diameters of necks of a cranked shaft
Fig. 2.167. Measurement of diameters of necks of a cranked shaft

Measure diameters of a neck of a shaft in the directions X and Y in two points (A and B), as is shown in drawing 2.167.
If diameters do not correspond to norm, replace a cranked shaft or прошлифуйте radical necks and establish bearings of the smaller repair size.
Maximum ovality: 0,05 mm.
Maximum ovality: 0,05 mm

Radical neck
Maximum ovality: 0,05 mm.

Crank finger
Maximum ovality: 0,05 mm
