4.1.16.1. Check of a bent shaft

PERFORMANCE ORDER
1. Check necks of a bent shaft for a roughness. Any noticeable roughness specifies that the bent shaft needs to be pereshlifovat or replaced.
2. If the bent shaft was перешлифован, check agnails around openings for lubricant. In the presence of agnails remove them with a small file or a shaber or carefully clear openings and channels of shaving.
3. Using a micrometer, measure diameter of radical and conrod necks of a bent shaft and compare results to the data provided in subsection 4.1.1 (for radical necks) and in subsection 4.1.1 (for conrod necks). You perform measurement of necks in several points, both on diameter, and on neck length that will allow to reveal ovality and conicity if they are present.
4. Check the surfaces of contact of oil consolidation on each end of a bent shaft for wear and other damages. If wear of a neck from consolidation big, then, perhaps, is required replacement of a bent shaft.
5. Wear of a conrod neck is characterized by metal knocks during the operation of the engine, especially under loading, on small turns and reduction of pressure of oil.
6. Wear of radical necks of a bent shaft is characterized by strong vibration of the engine and the metal knock increasing at increase in turns of the engine and also reduction of pressure of oil.
