3.5.13. Bent shaft

Check of an axial side play of a bent shaft

PERFORMANCE ORDER
1. Check of an axial side play of a bent shaft is made when it is installed in the block of cylinders of the engine.
2. Check of an axial side play is made by the indicator of 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 bent shaft. Moving a bent shaft from an emphasis against the stop along an axis measure the size of an axial side play. The result of measurement indicates uses of new persistent half rings the need.
3. In the absence of the indicator of hour type the axial side play of a bent shaft can be measured by a probe edge, having moved a bent shaft to one party against the stop and having measured a gap between the radical N2 bearing and a bent shaft.

Check

PERFORMANCE ORDER
1. Clear a bent shaft, using the corresponding solvent and drain it compressed air.
2. Check radical and conrod necks of a bent shaft for wear, corrosion and cracks.
3. 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.
4. 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.
5. Check necks of a bent shaft for a roughness. Any noticeable roughness specifies that the bent shaft needs to be pereshlifovat or replaced.
6. 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 and carefully clear openings and channels of shaving.
7. Using a micrometer measure diameter of radical and conrod necks of a bent shaft and compare results to technical requirements. 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.
8. 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.
9. On some engines if necks of a bent shaft were pereshlifovana on the repair size it is necessary to establish inserts of the increased size.
