GENERAL INFORMATION

Check of an axial side play of the crankshaft with use of the indicator of hour type


Check of an axial side play of the crankshaft

PERFORMANCE ORDER
1. Check of an axial side play of the crankshaft 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 a crankshaft end face. Moving the crankshaft 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 the crankshaft can be measured by a probe edge, having moved the crankshaft to one party against the stop and having measured a gap between the radical bearing No. 2 and the crankshaft.

Check

PERFORMANCE ORDER
1. Clear the crankshaft, using the corresponding solvent, and drain it compressed air.
2. Check radical and conrod necks of the crankshaft 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 the crankshaft 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 crankshaft necks for a roughness. Any noticeable roughness specifies that the crankshaft needs to be pereshlifovat or replaced.
6. If the crankshaft 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 the crankshaft 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 the crankshaft for wear and other damages. If wear of a neck from consolidation big, then, perhaps, is required replacement of the crankshaft.
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.
