2.33. Check of a cranked shaft

GENERAL INFORMATION

Check of a condition of teeths of a rotor of the VMT sensor on the forward party of a cranked shaft

Arrangement of pins in a forward counterbalance of a cranked shaft

PERFORMANCE ORDER
1. Clear a cranked shaft, using the corresponding solvent and drain it the compressed air.
2. Check radical and shatunny necks of a cranked shaft on wear, corrosion and cracks.
3. Wear of a shatunny neck is characterized by metal knocks at operation of the engine, especially under loading on small turns and reduction of pressure of oil.
4. Wear of radical necks of a cranked shaft is characterized by strong vibration of the engine and metal knock, I increase щимся at increase in turns of the engine, and also reduction of pressure of oil.
5. Check necks of a cranked shaft on a roughness. Any appreciable roughness specifies that a cranked shaft it is necessary перешлифовать or to replace.
6. If the cranked shaft was перешлифо van, check agnails round openings for greasing. In the presence of agnails remove them with a small file or a shaber and carefully clear openings and channels of shaving.
7. Using a micrometer measure diameter of radical and shatunny necks of a cranked shaft and compare results to technical requirements. Measurement of necks make in several points both on diameter, and on length of a neck that will allow to reveal ovality and a konusnost if they are present.
8. Check surfaces of contact of oil consolidation on each end of a cranked shaft on wear and other damages. If wear of a neck from consolidation big, probably is required replacement of a cranked shaft.
9. On some engines if necks of a cranked shaft were перешлифованы for the repair size it is necessary to establish loose leaves of the increased size.
10. Check, that teeths on a rotor of the sensor of the top dead point of a cranked shaft (see fig. were not damaged. Check of a condition of teeths of a rotor of the VMT sensor on the forward party of a cranked shaft).
11. Check a condition and existence of pins in a forward counterbalance of a cranked shaft (see fig. An arrangement of pins in a forward counterbalance of a cranked shaft).
