3.3.19. Conrod bearings
Check of a lubricant gap of conrod bearings
Arrangement of trailer gaps of piston rings (4-cylinder engine)
|
|
1. Top compression ring
2. Deepening (it is directed towards a forward part of the engine)
3. Lower oil scraper ring
4. Lower compression ring
5. Broad ring
6. Top oil scraper ring |
Arrangement of trailer gaps of piston rings (6-cylinder engine)
|
|
1. Piston of the right row
2. Lower oil scraper ring
3. The tag directed towards a forward part of the engine
4. The tag directed towards a forward part of the engine
5. Top oil scraper ring
6. Top compression ring
7. Broad ring
8. Lower compression ring
The arrangement of trailer zzor of rings of the piston of the left row is identical. |
| PERFORMANCE ORDER |
|
|
1. Clean the top insert of the bearing of a rod and establish it on a rod. Lubricant openings of a rod and an insert have to be combined. |
| 2. Clean the second insert and establish it in a rod cover. |
| 3. Arrange trailer gaps of piston rings as shown in rice. An arrangement of trailer gaps of piston rings (the 4-cylinder engine) and on rice. Arrangement of trailer gaps of piston rings (6-cylinder engine). |
| 4. Grease pistons and rings and squeeze piston rings by means of the compressor of piston rings. |
| 5. Turn a bent shaft so that the conrod bearing of the first cylinder was in the family way of the lower dead point, and grease cylinder walls. |
|
6. Check that the mark from above of the piston was turned forward. |
|
7. Press on the piston and install it in the cylinder. |
|
8. Put plastic pieces on each of bearings of rods parallel to an axis of a bent shaft. |
|
9. Establish covers of conrod bearings (tags on covers have to be directed towards a gas-distributing belt). Tighten bolts of covers according to the instructions provided in technical characteristics (see subsection 3.3.1.1., subsection 3.3.1.2.). |
|
10. Compare width of the crushed film to a special scale. |
| 11. If the size of a gap do not correspond demanded probably inserts of the wrong size are established. |
|
Final installation of pistons and rods
| PERFORMANCE ORDER |
| 1. Remove all traces of plastic. Check that the surface of inserts was absolutely pure, and oil them engine.
|
| 2. Establish a rod on a shaft neck, establish a cover of a rod and tighten nuts till the required inhaling moment. Installation of other rods is carried out similarly. |
| 3. After installation of all rods turn a bent shaft several times and check ease of the course.
|
| 4. Check an axial side play of rods.
