GENERAL INFORMATION

Causes of wear of bearings

1. Decrease in strength of metal; fragmentary scratches
2. It is incorrectly put; the bright (polished) strips
3. It is scratched гразью; dirt ate in the surface of the bearing
4. Lack of oil; the top layer was wiped
5. Excessive wear; the top layer was wiped on all surface
6. The bearing is deformed; the top layer was wiped around

In spite of the fact that at an engine partition old inserts of bearings are replaced with new, it is necessary to examine old inserts carefully. Survey of an insert can establish the reason of its wear.

Damage of bearings happens because of a lack of lubricant, availability of dirt and other foreign debris, an overload of the engine and corrosion. Anyway, the cause of damage of bearings needs to be removed prior to assembly of the engine.

For the correct selection of inserts be guided by the size of a lubricant gap which can be measured by means of a plastic measuring tape. At emergence of any problems with selection of inserts address experts.
