3.5.13. A cranked shaft

Check axial люфта a cranked shaft

PERFORMANCE ORDER
1. Check axial люфта a cranked shaft is made when it is established in the block of cylinders of the engine.
2. Check axial люфта is made by the indicator of the hour type which arm is established on the block of cylinders of the engine, and the measuring tip leans in an end face of a cranked shaft. Moving a cranked shaft from an emphasis against the stop along an axis measure size axial люфта. The result of measurement specifies in necessity of use of new persistent half rings.
3. In the absence of the indicator of hour type axial люфт a cranked shaft it is possible to measure by an edge probeа, having moved a cranked shaft to one party against the stop and having measured a backlash between radical bearing N2 and cranked shaft.

Check

PERFORMANCE ORDER
1. Clear a cranked shaft, using corresponding solvent and drain its compressed air.
2. Check up radical and шатунные necks of a cranked shaft on deterioration, corrosion and cracks.
3. Deterioration шатунной necks is characterised by metal knocks at engine work, especially under loading on small turns and reduction of pressure of oil.
4. Deterioration of radical necks of a cranked shaft is characterised by strong vibration of the engine and the metal knock increasing at increase of turns of the engine, and also reduction of pressure of oil.
5. Check up 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 перешлифован, check up agnails round apertures for greasing. In the presence of agnails remove their small file or шабером and carefully clear apertures and channels of a shaving.
7. Using a micrometer measure diameter radical and шатунных 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 конусность if they are present.
8. Check up surfaces of contact of oil consolidation on each end of a cranked shaft on deterioration and other damages. If deterioration of a neck from consolidation big replacement of a cranked shaft probably is required.
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.
