- Remove with a scraper, a file or an abrasive stone from lubricant openings of a bent shaft all agnails.
|
|
|
- Wash out a bent shaft solvent and drain compressed air (if it is available). Do not forget to clean a rigid brush channels of oil pipelines and to wash out them solvent.
|
- Check necks of radical bearings and bearings of rods for existence of uneven wear, furrows, dents and cracks.
|
|
- Carry out on each neck several times by a copper coin. If on a neck there are copper traces, then it too uneven and it it is necessary to grind.
|
- Check other parts of a bent shaft for existence of cracks and other damages. If necessary charge survey of a bent shaft of a mechanical workshop.
|
|
- Measure by a micrometer diameters of necks of radical and conrod bearings and compare results of measurements to requirements of the Size table and adjusting data at the end of the Management. Having measured in several points, it is possible to define what ovality have necks. To determine the size of conicity of necks, measure diameters of necks at their edges, near cheeks of cranks.
|
- If necks of a bent shaft are injured, have conicity, ovality or are worn-out over the limits specified in Tabliye of the sizes and adjusting data at the end of the Management send a bent shaft for grinding to a mechanical workshop. Make sure that after grinding of a bent shaft inserts of the correct size are applied.
|
|
- Check on the ends of a bent shaft condensed by epiploons, for existence of damages and wear. If the epiploon developed in a thorn a flute or if it has jags or scratches, then after assembly of the engine the new epiploon can proceed. In certain cases in a mechanical workshop can repair a thorn, напрессовав on it the thin plug. If repair is impossible, then it is necessary to establish other or new bent shaft.
|
- Check a condition of inserts of radical and conrod bearings (watch the Section Check of a Condition of Radical and Conrod Bearings).
