2.2.15.3. Measurement of diameter of a core of the valve

Measurement of diameter of a core
Fig. 2.140. Measurement of diameter of a core


Measure by a micrometer diameter of a core of each valve in the directions X and Y in three points (A, B, and C) as is shown in drawing 2.140.
If diameter does not correspond to norm, replace the valve.
Standard diameter:
- Admission: 5,470–5,485 mm;
- Release: 5,465–5,480 mm.
Maximum diameter:
- Admission: 5,440 mm;
- Release: 5,435 mm.
