GENERAL INFORMATION

Types of wear of radical and shatunny bearings

Check

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.

Causes of destruction of bearings of a cranked shaft are insufficient greasing because of the wrong assembly, pollution and penetration of extraneous particles, frequent overloads of the engine, corrosion, etc. Irrespective of the reason which has caused destruction of bearings, it is necessary to eliminate it.

Selection of radical bearings

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

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.

Definition of number of the loose leaf on engines of V6 3,0 l

1. Labels 1, 2 and 3

2. Otschetny label

3. Labels 0, 1 or 2

Number of the loose leaf is determined from the table by neck numbers on the block and to number on the crankshaft.

Number on the block of cylinders	1	2	1	3	2	1	3	2	3
Number on the crankshaft	0	0	1	0	1	2	1	2	2
Loose leaf number	1	2	2	3	3	3	4	4	5

Definition of number of the loose leaf on engines of V6 3,4 l

1. Labels 1, 2 and 3

2. Otschetny label

3. Labels 0, 1 or 2

Number of the loose leaf is determined from the table by neck numbers on the block and to number on the crankshaft.

Number on the block of cylinders	1			2			3
Number on the crankshaft	0	1	2	0	1	2	0	1	2
Loose leaf number	1	2	3	3	3	4	2	4	5

Selection of shatunny bearings

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

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