3.1.2.13. Cranked shaft

Check of a technical condition

PERFORMANCE ORDER
1. Wash out a cranked shaft solvent and dry a stream of the compressed air (at existence).
2. Check uniformity of wear of radical and shatunny necks, existence on them задиров, cracks or a local erosion.
3. Remove from oil openings all agnails by means of a grinding stone, a rigid brush or a file.
4. Clean oil channels a rigid brush and wash out a strong stream of solvent.
5. Check on existence on other parts of the crankshaft of cracks and mechanical damages. For identification of the latent defects it is recommended to hand over the crankshaft in a car-care center workshop.
6. Measure by a micrometer diameter of radical and shatunny necks, compare result to standard value. Check ovality of radical and shatunny necks of a shaft, having measured their diameter in several points on a circle. Check a konusnost of necks for what measure diameter of a neck in places about shaft counterbalances, and results compare.
7. It is necessary to check also crankshaft palpation though prisms of the big size will be necessary for this measurement. In the absence of the necessary equipment, palpation can be checked in repair trucks.
8. In the presence of damages on shaft necks and also if ovality, the konusnost and wear of necks exceed the established limits, it is necessary to hand over a shaft on repolishing in a specialized workshop. After shaft repair, it is necessary to replace radical and shatunny bearings repair.
9. Check existence of signs of wear and damages on necks under forward and back epiploons. If on a neck the deep flute of development from a working edge of an epiploon was formed, there are scratches or other damages, the new epiploon will not condense a neck. In certain cases the shaft can be repaired by a napressovka of the thin plug on a condensed neck for what it is necessary to address in a workshop. If repair is impracticable, it is necessary to replace the crankshaft new or restored.
