3.1.2.12. Radical and conrod bearings


Types of wear of radical and conrod bearings

A. Scratches because of dirt hit
B. Insufficient lubricant, local wipe
C. Wrong installation of bearings
F. Fatigue wear
D. Conicity of necks, a bearing covering wipe from all surface on bearing length
E. Formation of a fillet on an edge of the bearing

Check

PERFORMANCE ORDER
1. The bearings which were in operation should be stored in the place of their installation for careful check as wear tracks on these details allow to restore the general condition of the engine. Inserts of bearings are subdivided into dimensional groups on thickness specified by color marking.
2. Insufficient lubricant, presence of dirt and foreign particles, an overload of the engine and corrosion are causes of destruction of bearings of a bent shaft. Irrespective of the reason which caused destruction of bearings it should be eliminated before final assembly of the engine.
3. Get bearings from the block of cylinders and lay out inserts on a pure surface as their installation.
4. For the prevention of the accelerated wear because of pollution maintain purity at assembly of the engine. It is in use recommended to a thicket to change oil and filters.
5. At insufficient lubricant, there is a material of a covering of the bearing is wiped from a steel basis, the bearing is painted from an overheat (the bluish shade is observed).
6. At the movement in the modes, heavy for the engine (with completely open butterfly valve, or with a small speed on an overgear) there is a bearing covering separation from a steel basis in the form of small particles, bearings are exposed to fatigue wear.
7. Frequent trips on small distances can be the reason of corrosion wear of bearings as because of insufficient warming up do not manage to be removed the condensed moisture.
8. The wrong installation of bearings at assembly also results in their premature wear. If the gap in bearings is less than norm, then their lubricant is complicated that results in wear as well as owing to "oil to starvation".
9. At assembly do not touch with fingers insert surfaces.
10. Inserts of radical and conrod bearings at capital repairs are subject to obligatory replacement.
