Check of a condition of a cranked shaft

 PERFORMANCE ORDER

  1. Grinding stone, надфилем or a scraper remove agnails from edges of oil apertures.

Removal of facets from edges of oil apertures

  1. Wash out a cranked shaft solvent, then carefully dry, whenever possible having taken advantage of compressed air. Do not forget to clean a rigid brush oil apertures. Then also wash out their solvent.

Procleaning маслотоков by means of a cylindrical brush

At use of compressed air do not forget to put on goggles!

  1. Check up radical and шатунные necks of a cranked shaft on presence задиров, cavities, cracks and signs of non-uniform deterioration.
  2. Examine all surface of a shaft on presence of cracks and other damages. For revealing of the latent cracks it is necessary to resort to магнитопорошковой дефектоскопии, - give a shaft to a car-care centre workshop.
  3. By micrometer measure diameters radical and шатунных necks of a shaft Measurement of diameter of each neck make in several points on length and perimetre that will allow to estimate its size конусности and ovality which should not fall outside the limits admissible ranges (see Specifications in the Head Engines). It is necessary to estimate also size of palpation of a cranked shaft, - be required pair of V-shaped blocks and циферблатный a measuring instrument плунжерного type In the absence of necessary stock address for the help to experts of car-care centre.
Measurement of diameters подшипниковых necks of a cranked shaft by means of a micrometer

Measurement of size of radial palpation of a cranked shaft

  1. In case deterioration/konusnost/ovality of necks exceeds admissible size, or mechanical damages of surfaces take place, it is necessary to give a cranked shaft in проточку. After проточки a shaft it is necessary to pick up new loose leaves radical and-or шатунных bearings of the corresponding repair size.
  2. Check up a condition сальниковых necks on both pins of a cranked shaft. Presence of the developed flutes, agnails or задиров will lead to an exit of new epiploons out of operation in the near future. In certain cases pins can be restored a way проточки and напрессовки on them of special thin-walled plugs. If such regenerative repair is not obviously possible, replace a shaft.
  3. Check up a condition of loose leaves radical and шатунных bearings (the Section Check of a condition radical and шатунных bearings of a cranked shaft see).
