Removal

PERFORMANCE ORDER
1. Disconnect a ventilation hose картера.
2. Remove a pulley of the water pump and a cranked shaft.
3. Remove a casing of a gear belt.
4. Take away a roller of a tension of a gear belt to the water pump and temporarily fix it in this position.
5. Remove a gear belt from a camshaft pulley.
6. Turn out screws and remove the central cover.
7. Remove the block of coils of ignition.
8. Turn out bolts and uncover heads of cylinders.
9. Remove a camshaft pulley.
10. Remove covers of bearings of a camshaft and a chain.
11. Remove camshafts.
12. Remove hydraulic jacks of backlashes of valves.

Check

PERFORMANCE ORDER
1. Check up a camshaft on absence of non-uniform deterioration, cracks or damages.
2. In two points measure height of each cam of a camshaft.

Nominal height of cams of a camshaft of inlet valves: 43,4483 mm
Nominal height of a camshaft of final valves: 43,8489 mm
Is minimum admissible height of cams of a camshaft of inlet valves: 42,9484 mm
Is minimum admissible height of a camshaft of final valves: 43,3489 mm

3. Check up surfaces of cams on absence of non-uniform deterioration and damages.
4. Check up each bearing on absence of damages. If the working surface of the bearing is excessively damaged, replace a head of cylinders or a cover of the bearing of a camshaft.

Axial люфт a camshaft: 0,1–0,2 mm

Forward sealing ring of a camshaft

PERFORMANCE ORDER
1. Check up working edges of a sealing ring on absence of deterioration. If the working edge is worn out or damaged, replace a sealing ring.
2. Check up the surface of a camshaft contacting to a sealing ring. If this surface is worn in regular intervals out, replace a camshaft.

Hydraulic jacks of backlashes of valves


Fill the hydraulic jack of backlashes of valves with engine oil, hold vertically and hand fingers compress it from two parties.


The basic malfunctions of hydraulic jacks of backlashes of valves, the reasons and elimination methods are resulted in the table.

Malfunction
The possible reasons
Elimination method
Temporary noise at start of the cold engine. The normal phenomenon Noise disappears after warming up of engine oil and achievement of normal pressure
Continuous noise after the engine was not started within 48 hours. Oil from chambers of hydraulic jacks of backlashes of valves has flowed out and air has got to them Noise will disappear through 15 mines of work of the engine when the cranked shaft of the engine will reach frequencies of rotation of 2000-3000 mines-1
The prevention

Do not increase frequency of rotation of a cranked shaft of the engine above 3000 mines-1 as it is possible to damage hydraulic jacks of backlashes of valves.


Continuous noise after start-up of the engine and replacement of a head of cylinders There is not enough oil in oil channels of the engine
Continuous noise after long start-up of the engine by a starter or a towage method Oil from chambers of hydraulic jacks of backlashes of valves has flowed out and air has got to them
Continuous noise, after replacement of hydraulic jacks of backlashes of valves
Continuous noise, on frequency of idling after movement on high speed Engine oil level too low or too high Check up engine oil level
Air considerable quantity is dissolved in oil after high frequency of rotation Check up system of giving of oil
Deterioration of properties of engine oil Check up quality of oil and, if necessary, replace it
Noise proceeds more than 15 mines Low pressure in greasing system Check up pressure in greasing system
Hydraulic jacks of backlashes of valves are faulty Remove a head of cylinders and, pressing hydraulic jacks of backlashes of valves, check up size of their compression

Chain

Check up a chain on absence of non-uniform deterioration, cracks or damages and, if necessary, replace it.


Installation

PERFORMANCE ORDER
1. Establish hydraulic jacks of backlashes of valves.
2. Establish a chain on asterisks of camshafts how it is shown in drawing.
3. Before installation apply a thin film pure engine oil on all surfaces of sliding of camshafts. Establish camshafts.
4. Establish covers of bearings of camshafts. Check up the identification labels defining camshafts of inlet or final valves.
Camshaft of inlet valves: I
Camshaft of final valves: Е
5. Tighten bolts of fastening of covers of bearings the demanded moment.

The inhaling moment: 12–14 Н•м

6. Grease with engine oil working edges and an external surface of a sealing ring and the special tool 09221–21000 establish a sealing ring on a forward part of a camshaft.

Hammer blows on the special adaptation establish a sealing ring against the stop in a nest.
7. Establish a pulley of a camshaft and fix its bolt.

The inhaling moment: 80–100 Н•м

8. Combine an adjusting label of a camshaft and an adjusting label of a pulley of a cranked shaft with indexes, thus the piston of 1st cylinder will be in ВМТ in a compression step.
9. Establish a cover of a head of cylinders and tighten bolts of fastening of a cover the demanded moment.

The inhaling moment: 8–10 Н•м

10. Establish high-voltage wires, coils of ignition and the central cover.
11. Establish a gear belt and tighten the mechanism of a tension of a gear belt.
12. Establish casings of a gear belt.
13. Establish a pulley of the water pump.
