2.2.6.2. Check of a head of the block of cylinders

Fig. 2.82. Scheme of check of a buckling of surfaces of a head of the block of cylinders


By means of a ruler and the flat probe check a buckling of surfaces of a head of the block of the cylinders interfaced to the surface of the block of cylinders and to surfaces of inlet and final collectors (fig. 2.82).
Maximum admission of a buckling:
the party of the block of cylinders – 0,05 mm;
the party of an inlet collector – 0,08 mm;
the party of a final collector – 0,08 mm.
If the size of the plane of a buckling exceeds the most admissible, replace a head of the block of cylinders. By means of dye check existence of cracks in combustion chambers, inlet and final channels and for surfaces of a gas joint. In the presence of cracks replace a head of the block of cylinders.
