4.4.24.3. Check of cylinders

PERFORMANCE ORDER
1. Measure ovality and conicity of cylinders.
2. Measure diameter of each cylinder in the top, average and lower its parts parallel to an axis of a bent shaft. Measure diameter of each cylinder in the top, average and lower its parts perpendicular to an axis of a bent shaft. Conicity of the cylinder is calculated as a difference between the top and lower diameters. Ovality – as a difference between parallel and perpendicular measurements.
3. If the received results do not coincide with technical requirements, cylinders need to be processed in a specialized workshop.
