THE GENERAL DATA

Kinds of deterioration radical and шатунных bearings

Check

Radical and шатунные bearings at engine major repairs are subject to the obligatory replacement, however the bearings which were in operation should be checked up carefully to restore the general condition of the engine at the moment of repair.

Sources of rupture of bearings of a cranked shaft are insufficient greasing because of wrong assemblage, pollution and penetration of extraneous particles, frequent overloads of the engine, corrosion, etc. Irrespective of the reason which have caused destruction of bearings, it should be eliminated.

Selection of radical bearings

If bearings of standard dimensional groups the new bearing steals up under numbers put on replaced, and also under numbers on the block of cylinders and коленвале are established.

Places of drawing of standard dimensional groups of radical bearings on 4-cylinder engines

Number on the block should coincide with number on the bearing.

Selection шатунных bearings

If bearings of standard dimensional groups the new bearing steals up under numbers put on replaced and on a cover of a rod are established.

After selection measure a backlash in necks (subsection 3.3.9.3, subsection 3.3.12.2 see).
