- With grinding stone, file or scraper remove agnails from edges of oil openings.

- Wash out a cranked shaft solvent, then carefully dry, having whenever possible used the compressed air. Do not forget to clean a rigid brush oil openings. Then wash out them solvent.

When using the compressed air do not forget to put on goggles! |
|
- Check radical and shatunny necks of a cranked shaft on existence задиров, cavities, cracks and signs of non-uniform wear.
- Examine all surface of a shaft on existence of cracks and other damages. For identification of the hidden cracks it is necessary to resort to a magnitoporoshkovy defektoskopiya — give a shaft to a car-care center workshop.
|
- By micrometer measure diameters of radical and shatunny necks of a shaft. Measurement of diameter of each neck make in several points on length and perimeter that will allow to estimate size of its konusnost and ovality, which should not fall outside the limits an admissible range (see. Specifications).
|
|
- It is necessary to estimate also size of palpation of a cranked shaft — be required V-shaped steam of blocks and a digital measuring instrument of plunzherny type. In the absence of necessary stock address for the help to specialists of car-care center.
|
|
- In case wear / konusnost/ovality of necks exceeds admissible size, or mechanical damages of surfaces take place, it is necessary to give a cranked shaft to a pro-point. After a pro-point of a shaft it is necessary to pick up new loose leaves of radical and/or shatunny bearings of the corresponding repair size.
|
- Check a condition of omental necks on both pins of a cranked shaft. Existence 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 by a pro-point and napressovka way on them special thin-walled plugs. If such regenerative repair is not obviously possible, replace a shaft.

|
- Check a condition of loose leaves of radical and shatunny bearings (see. Check of a condition and selection of loose leaves of radical and shatunny bearings of a cranked shaft).
