5.19. Replacement of sealing rings

GENERAL INFORMATION

Removal of laying from drive platinum

Removal of a plate of a drive on models with an automatic transmission

Measurement of length of a bolt of fastening of a plate of a drive

Sealing ring of the camshaft operating exhaust valves on models with system of injection of CIS fuel

PERFORMANCE ORDER
1. Remove a krylchatka of the fan of a radiator and the hydraulic coupling.
2. Remove a plastic casing from a forward cover of a head of the block of cylinders.
3. Disconnect the central high-voltage wire from a cover of the distributor of ignition.
4. Unscrew bolts, remove and move aside a cover of the distributor of ignition, without disconnecting from it other high-voltage wires.
5. Unscrew screws and remove a rotor of the distributor of ignition.
6. Unscrew the central bolt and remove a drive of a rotor of the distributor from a camshaft end face.
7. Remove the filter and laying from the top cover of a driving chain.
8. Using a screw-driver edge, remove an old sealing ring.
9. Alternatively drill in a sealing ring two small openings located in the opposite ends of a sealing ring. Screw in two self-cutting screws in the drilled openings of a sealing ring and, using flat-nose pliers, extend for heads of screws a sealing ring.
10. Clear a nest of a sealing ring.
11. To exclude damage of working edges of a sealing ring at its installation, wind a camshaft end face with a sticky tape.
12. Using a tubular opravka of the corresponding diameter, establish a new sealing ring.
13. Remove a sticky tape from a camshaft end face.
14. Further installation is made in sequence, return to removal.
15. Forward sealing ring of a cranked shaft.
16. Remove a pulley cranked a shaft / quencher of krutilny fluctuations and a nave.
17. Measure depth of installation of a sealing ring.
18. Using a screw-driver edge, take a sealing ring.
19. Alternatively drill in a sealing ring two small openings located in the opposite ends of consolidation. Screw in two self-cutting screws in the drilled openings of a sealing ring and, using flat-nose pliers, extend for heads of screws a sealing ring.
20. Clear a nest of a sealing ring.
21. Not to damage working edges of a sealing ring at its installation, wind with a sticky tape a forward end face of a cranked shaft.
22. Dip a new sealing ring into pure engine oil and, using a tubular opravka of the corresponding diameter, establish a new sealing ring in a nest on earlier measured depth.
23. Remove a sticky tape from an end face of a cranked shaft.
24. Establish a pulley cranked a shaft / quencher of krutilny fluctuations and a nave.

Back sealing ring of a cranked shaft

PERFORMANCE ORDER
1. Remove a drive flywheel / plate.
2. Replace a back sealing ring of a cranked shaft in the same way, as well as a forward sealing ring of a cranked shaft. After removal of a sealing ring check the surface of a cranked shaft contacting to a sealing ring, and at wear of this surface of a cranked shaft, it is necessary to replace a cranked shaft.
3. Establish a drive flywheel / plate.
