Check axial люфта коленвала with use of the indicator of hour type

Check axial люфта коленвала

1. Check axial люфта коленвала 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 коленвала. Moving коленвал 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 коленвала it is possible to measure by an edge щупа, having moved коленвал to one party against the stop and having measured a backlash between the radical bearing №2 and коленвалом.


1. Clear коленвал, using corresponding solvent, and drain its compressed air.
2. Check up radical and шатунные necks коленвала 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 коленвала 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 коленвала on a roughness. Any appreciable roughness specifies that коленвал it is necessary перешлифовать or to replace.
6. If коленвал 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 коленвала 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 коленвала on deterioration and other damages. If deterioration of a neck from consolidation big, that, probably, is required replacement коленвала.
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.
