5.17. Radical and shatunny bearings - check and selection1. Radical and shatunny bearings at major maintenance of the engine are subject to the obligatory replacement, however the bearings which were in operation should be checked carefully to restore the general condition of the engine at the moment of repair.
2. Causes of destruction of bearings of a cranked shaft are insufficient greasing because of the wrong assembly (overlapping of channels, a small gap), pollution and penetration of extraneous particles (untimely replacement of oil and the filter, violation of consolidations), frequent overloads of the engine and corrosion (is caused by frequent short trips). Irrespective of the reason which has caused destruction of bearings, it is necessary to eliminate it.
3. If the crankshaft is not перешлифовываться, it is necessary to pick up bearings of standard dimensional group (after repolishing of necks only repair bearings are established). After selection it is necessary to check gaps in bearings.

5. On 4-cylinder engines on the 2nd and 4th necks group B loose leaves (if the crankshaft not перешлифовывался) are established. The group of loose leaves of necks 1,3 and 5 (And or In) is beaten out on the pallet (photo).

6. On V6 engines of number it is necessary to define in addition dimensional groups of loose leaves and a radical support, and then by the sum of these numbers (or from the table) to determine group of the loose leaf (photo).
