1.1.11. Camshafts and yokes
Removal
|
|
| 1. Disconnect a "weight" wire from the storage battery.
2. Merge cooling liquid.
3. Remove the wide hose connecting the air filter and a cover of a head of the block of cylinders.
4. Remove the air filter.
5. Remove casings of a gear belt.
6. Uncover heads of the block of cylinders and the sensor of an angle of rotation.
|
|
7. Turn out bolts and remove pulleys from camshafts. |
8. Turn out bolts and covers of bearings, camshafts, yokes and jacks of gaps. |
|
Check
Yokes
|
|
|
|
1. Check ease and smoothness of rotation of a roller. |
2. To check a roller. Replace it, there are dents, damage or evidence of jamming.
3. Check a working end face of a yoke. If the end face of a core is worn-out or расклепан, replace the valve.
|
|
Camshafts
|
|
| 1. Check necks of camshafts on lack of non-uniform wear, cracks or damages.
2. Check contours of cams of camshafts on lack of wear or damages. In two points measure height of each cam of a camshaft.
- Nominal height of cams of a camshaft of the managing director of inlet valves: 35,493 mm
- Nominal height of a camshaft of the managing director of final valves of cars with MKP: 35,317 mm
- Nominal height of a camshaft of the managing director of final valves of cars with AKP: 35,204 mm
- Minimum admissible height of cams of a camshaft of the managing director of inlet valves: 34,993 mm
- Minimum admissible height of a camshaft of the managing director of final valves of cars with MKP: 34,817 mm
- Minimum admissible height of a camshaft of the managing director of final valves of cars with AKP: 34,704 mm

Installation
|
|
|
|
1. Establish camshafts on a head of the block of cylinders.
|
|
- Before installation apply a thin film pure engine oil on all surfaces of sliding of camshafts.
- The camshaft operating inlet valves, has a groove on a back part for a drive of the sensor of an angle of rotation.
|
|
|
|
2. Establish covers of bearings of camshafts. Check the identification labels defining camshafts of inlet or final valves.
- L–a camshaft operating inlet valves.
- R–a camshaft operating final valves.
|
|
|
3. Be convinced that the camshaft easily rotates by hand. After check remove covers of bearings and camshafts and then establish yokes. |
|
|
4. Be convinced that adjusting pins in a camshaft end face from a pulley are directed up. |
|
|
5. In sequence shown in drawing in two or three stages tighten bolts of fastening of covers of bearings the demanded moment.
|
|
Tighten evenly bolts of fastening of covers.
Inhaling moment: 19–21 N • m |
|
|
|
6. Using special tools for installation of oil consolidation of a camshaft and directing (09221–21000,09221–21100), press oil consolidation of a camshaft. Before a press fitting of consolidation grease with engine oil an external surface of consolidation. Insert oil consolidation on a forward end face of a camshaft and establish it, striking with a hammer on the adaptation, before its complete installation. |
7. Establish a pulley of a camshaft and fix it a bolt.
Inhaling moment: 80–100 N • m
8. Establish a cover of a head of the block of cylinders. Put hermetic in places shown in drawing. Inhaling moments
- Bolts of fastening of a cover of a head of the block of cylinders: 8–10 N • m
- Central bolts of fastening of a cover of a head of the block of cylinders: 4–5 N • m
Hermetic
- In places And: No. 10 or equivalent
- In places In: No. 1212 D or equivalent
Length of a bolt x diameter:
- 25 x 6 mm;
- 20 x 6 mm;
- 15 x 6 mm.
|
|
9. Screw spark plugs, establish the ignition coil, connect the socket, then establish the central cover. |
|
|
10. Arrange above an adjusting pin of a pulley of a camshaft of the managing director inlet valves. |
|
|
11. Combine a label of the sensor of a camshaft with a groove in distributive to a shaft (from an inlet collector) and fix the sensor bolts.
|
|
The sensor of an angle of rotation of a camshaft can be established, even when the adjusting pin will be located from the opposite side work of system of injection of fuel and installation of a corner of an advancing of ignition, however, is broken. |
|
12. Establish the sensor of an angle of rotation of a camshaft on a head of the block of cylinders. |
