3.1.2.1.10. Camshaft

GENERAL INFORMATION

The sequence of fastening of bolts of covers of bearings of the camshaft (cm3 model 1998 with 16 valves)


Removal

PERFORMANCE ORDER
1. To remove a weight wire from the accumulator.
2. To uncover a head of the block of cylinders.
Cm3 models 1905 with 16 valves
3. To unscrew a bolt from a plastic casing of a pulley of the pump of the amplifier of steering.
4. To take off a driving belt from the leading pulley of the steering drive.
5. To unscrew a bolt and to remove a pulley from the end of the camshaft.
6. To remove pulleys from both camshafts.
7. To uncover the breaker distributor and a distributor rotor.
8. To unscrew a bolt and to remove the distributor of ignition and a disk of consolidation.
9. To unscrew a bolt of fastening of an internal casing of a gear belt of the drive from a head of the block of cylinders.
10. To release a pipe of supply of oil to covers of bearings of the camshaft and to remove it.
11. To turn the camshaft so that turnkey vents were approximately in the family way 3 hours.
12. Evenly and gradually to weaken covers of bearings of the camshaft that reduces pressure of a valvate spring upon a bearing cover. As soon as pressure of springs is taken off, bolts can be completely unscrewed and removed.
13. To uncover bearings, noting location of probes.
14. To remove camshafts from a head of the block of cylinders, consolidations and a clamp of axial movement.
15. Using a rubber sucker, to take a pusher of the valve and it is obligatory to turn it for an effluence exception of a pusher of engine oil. To note a location of pushers for repeated installation them on the places.
Cm3 models 1998 with 16 valves
16. To remove pulleys from the camshaft and where it is necessary, also to remove the vacuum pump since the left forward end of a head of the block of cylinders.
17. To unscrew six bolts fixing an internal casing of a gear belt to the block of cylinders of the engine and to remove a casing.
18. To release a pipe of supply of oil to covers of bearings of the camshaft and to remove it.
19. To uncover the breaker distributor and a distributor rotor.
20. To unscrew a bolt and to remove the distributor of ignition and a disk of consolidation.
21. Covers of the bearing of the camshaft are numbered from 1 to 5, and the cover 1 is located from the drive.
22. Removal of covers is made in the sequence, return shown in the drawing Sequence of Fastening of Bolts of Covers of Bearings of the Camshaft (cm3 models 1998 with 16 valves).
23. Evenly and gradually to weaken covers of bearings of the camshaft that reduces pressure of a valvate spring upon a bearing cover. As soon as pressure of springs is taken off, bolts can be completely unscrewed and removed.
24. To uncover bearings, noting location of probes.
25. To remove camshafts from a head of the block of cylinders, consolidations and a clamp of axial movement.
26. The camshaft operating inlet valves has a groove for the vacuum pump of the brake system in the left end.
27. Using a rubber sucker, to take a pusher of the valve and it is obligatory to turn it for an effluence exception of a pusher of engine oil.
28. To note a location of pushers for repeated installation them on the places.
All other models
29. To remove a pulley from the camshaft.
30. To remove the ignition distributor.
31. To remove the fuel pump.
32. To release a pipe of supply of oil to covers of bearings of the camshaft and to remove it.
33. Covers of the bearing of the camshaft are numbered from 1 to 5, and the cover 1 is located from the drive.
34. Evenly and gradually to weaken covers of bearings of the camshaft that reduces pressure of a valvate spring upon a bearing cover. As soon as pressure of springs bolts can be taken off are completely unscrewed and removed.
35. To uncover bearings, noting their orientation.
36. To remove the camshaft from a head of the block of cylinders.

37. Using a rubber sucker, to take adjusting washers of a gap of valves. To note a location of pushers for repeated installation them on the places.


Check

PERFORMANCE ORDER
1. To check a condition of working surfaces of bearings of the camshaft, a profile of a cam and a neck of a shaft. At wear of bearings of the camshaft in a head the head of the block of cylinders is subject to replacement.
2. To check a condition of working surfaces of a pusher of the valve.
3. If during the operation of the heated-up engine with hydraulic pushers the knock of valves is heard, the hydraulic pusher is subject to check and, perhaps, replacement.
4. On models 1580 of cm3 and 1905 cm3 to check a fork of axial fixing of a shaft.

Pipe of supply of oil to covers of bearings

And – a pipe of supply of oil to covers of bearings of early models without consolidation;

In – a pipe of supply of oil to covers of bearings of later models with laying of round section

Installation
Prevention

If new hydraulic pushers are established, they need to be filled with oil. Pushers place in a bathtub with engine oil and repeatedly squeeze them.


Before installation of the camshaft to grease all working surfaces with a thin layer of engine oil.

PERFORMANCE ORDER
Models 1905 of cm3 and 1998 cm3 with 16 valves
1. To install camshafts on a head. To temporarily establish segment splines and pulleys. To turn camshafts so that turnkey vents were approximately in situation 3 hours (see rice. The sequence of fastening of bolts of covers of bearings of the camshaft (cm3 model 1998 with 16 valves)).
2. To establish covers of bearings and to tighten them evenly and gradually.
3. To establish a pipe of supply of oil to covers of bearings of the camshaft together with laying of round section, having checked purity of openings. At installation of a pipe of supply of oil to covers of the bearing of the camshaft not to displace laying of round section.
4. To establish an internal casing of a gear belt.
5. To install new consolidations on the camshaft.
6. To install the ignition distributor.
7. To install pulleys on the camshaft.
8. To establish a pulley of the drive of the amplifier of steering and its casing.
