2.3. Hydraulic compensators of gaps of valves

Removal

PERFORMANCE ORDER
1. Disconnect a wire from the negative plug of the rechargeable battery.
2. Turn out screws and remove the top cover from a cover of a head of the block of cylinders.
3. Remove coils of ignition and high-voltage wires.
4. Disconnect a hose of positive ventilation of a case and a hose of ventilation.
5. Take off a gear belt.
6. Turn out bolts and uncover a head of the block of cylinders.

Prevention

Before removal of a cover of a head of the block of cylinders combine tags on pulleys of camshafts with indexes on a cover of a head of the block of cylinders.


7. Turn out bolts and remove the sensor of an angle of rotation.
8. Turn out bolts and remove pulleys of camshafts.
9. Gradually, in a certain sequence, for 5–6 stages, weaken and turn out bolts of fastening of covers of bearings of camshafts.
10. Remove camshafts.
11. Note an arrangement of hydraulic compensators of gaps of valves for their repeated installation on the places.

Prevention

If hydraulic compensators of gaps of valves are not installed on the places, it will result in the increased wear them and camshafts.


12. Take hydraulic compensators of gaps of valves from a head of the block of cylinders.
13. You store hydraulic compensators of gaps of valves in the turned view in a container with engine oil.

Installation
PERFORMANCE ORDER
1. Apply a thin film of pure engine oil on the external surface of hydraulic compensators of gaps of valves.
2. Install hydraulic compensators of gaps of valves on the places in a head of the block of cylinders.
3. Check that hydraulic compensators of gaps of valves easily move in openings of a head of the block of cylinders.
4. Grease with a thin layer of pure engine oil of a neck of camshafts and the working surfaces of bearings of camshafts. Install camshafts so that adjusting pins were directed up.
5. Establish covers of bearings of camshafts according to numbering of covers. Shooters on covers have to be directed forward.
6. Fix covers of bearings of camshafts by bolts, having tightened them in a certain sequence for 5–6 stages.

Inhaling moment: 17,6–26,5 N • m

7. Grease the external surfaces and working edges of new sealing rings of camshafts with a thin layer of pure engine oil.
8. Using a tubular mandrel, the corresponding diameter, and the hammer establish sealing rings so that the end face of a sealing ring settled down flush with a head of the block of cylinders.

9. Establish pulleys of camshafts, at the same time a tag of I on a pulley camshaft of inlet valves and a tag E on a pulley of the camshaft of final valves have to be combined with adjusting pins. Fix pulleys of camshafts by bolts.

Inhaling moment: 49–60,8 N • m
10. Install the sensor of an angle of rotation and fix it by bolts.

11. Establish a cover of a head of the block of cylinders and fix it by bolts.

Inhaling moment: 7,8–11,8 N • m

12. Establish a gear belt.
13. Connect a hose of positive ventilation of a case and a hose of ventilation.
14. Establish high-voltage wires and coils of ignition.
15. Establish the top cover on a cover of a head of the block of cylinders and fix it by screws.

Inhaling moment: 4,9–8,8 N • m

16. Connect a wire to the negative plug of the rechargeable battery.
