Коленвал and the block of cylinders
The prevention Tighten only динамометрическим a key. Use of a key of "rattle" can lead to breakages.
The block of cylinders in gathering (4-cylinder models)
1. Bolts
2. Loose leaves 1, 2, 4 and 5th radical bearing
Are established in covers 1, 2 and 5th radical bearings without an oil flute, and in a cover of 4th bearing with мясляной a flute
3. A lining
Is subject to obligatory replacement
4. The forward holder of an epiploon
5. An epiploon
6. 20 Н.м.
7. A ring lining
At damage replace
8. 25 Н.м.
9. An epiploon
Take an epiploon from the case a stripper 10-203
Before installation slightly grease working and external edges of an epiploon
10. The epiploon case
11. An intermediate shaft
At first remove the ignition distributor

12. Loose leaves 1, 2, 4 and 5th radical bearing
Are established in bed of the block of cylinders with an oil flute
13. The loose leaf of 3rd radical bearing
The persistent bearing is established in bed of the block of cylinders with an oil flute (the repair bearing has an assembly fillet)
14. A persistent half ring from outside the block of cylinders
15. The loose leaf of 3rd radical bearing
16. The directing bearing
Put greasing on a basis дисульфида molybdenum
17. Коленвал
18. A persistent half ring
Watch correctness of installation
19, 20. Covers of radical bearings
Pay attention to asymmetry of bed of the loose leaf and fixing inflow |
