3.4.17. Check of a cranked shaft

1. Wash out a cranked shaft solvent and carefully dry. Surely clean oil channels a rigid brush and wash out a strong stream of solvent. Remove the solvent remains, having blown channels the compressed air.
2. The solvent which has remained in oil channels, will dilute oil at the first start-up of the engine that can cause serious damages. Check uniformity of wear of radical and shatunny necks, existence on them задиров, cracks or a local erosion. Check all cranked shaft on existence of cracks and damages.
3. Measure by a micrometer diameter of radical and shatunny necks, compare result to the value given in the management. 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 counterbalances, and results compare. If the micrometer is absent, measurements can be carried out in workshops for an acceptable payment.
4. In the presence of damages 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 repair of a shaft it is necessary to replace radical and shatunny bearings repair.
