3.2.2.5. Коромысла and platens коромысел
THE GENERAL DATA

4-CYLINDER ОДНОВАЛЬНЫЕ PETROL ENGINES

Details газораспределительного the mechanism on all 4-cylinder petrol engines

1 – a nut of fastening of a cover of the platen коромысел

2 – springs коромысел

3 – the platen коромысел

4 – коромысло the valve

5 – a platen cover

The gazoraspredelitelnyj mechanism

1 – газораспределительный the mechanism of 4-cylinder petrol engines

2 – a spring

3 – ориентационные labels on коромысле

4 – the platen with большей in the length

5 – a platen cover

6 – ориентационные platen labels коромысел

7 – a camshaft

8 – platen installation коромысел on 4-cylinder petrol engines

9 – sequence of an inhaling of bolts and nuts of covers of platens

Removal

PERFORMANCE ORDER
1. Disconnect the battery from weight. Uncover the mechanism timing.
2. Ослабьте an inhaling of nuts of fastening of covers of platens коромысел. Nuts turn on gradually, since extreme covers.
3. Turn away a nut of covers of platens коромысел. Remove platens in gathering with коромыслами.
4. Remove from spring platens, коромысла and covers. Spread out details so that at assemblage to establish them on former places.
5. Before assemblage grease platens, коромысла and cores of valves with pure oil for the engine.

Installation

PERFORMANCE ORDER
1. Сориентируйте platens. The long platen should be from outside final valves, and the short platen – from outside inlet. Adjusting labels on platens should be turned towards a forward part of the engine.
2. Collect platens with коромыслами and covers. Covers сориентируйте so that number of the cylinder which has been beaten out in the top part of covers has been turned towards a forward part of the engine.
3. Combine a label on a cover коромысла 1st cylinder with a label on the platen коромысел, put from outside inlet or final valves.
4. Combine apertures under hairpins in the platen коромысел with corresponding apertures in covers of platens. Be convinced that the size of a ledge of the platen of final valves concerning a cover is more than the platen of inlet valves.
5. Establish springs коромысел between the platen and коромыслом.
6. Be convinced that ориентационные labels on the platen (кернения) are turned upwards, establish the platen in gathering with коромыслами on hairpins of a head of cylinders. Combine a label on a camshaft with a label on a cover of the platen of 1st cylinder.
7. Tighten nuts of fastening of covers of platens with the moment 21 Н.м., and bolts – with the moment 8 Н.м.
The prevention

At a tightening of nuts keep springs коромысел, breakage of springs otherwise is possible. An inhaling begin with the central nut, being displaced to periphery.


8. Adjust backlashes in valves (subsection 3.1.5 see). Establish a cover, having replaced a lining and a sealant. Check up installation of the moment of ignition.

DIESEL ENGINES

Sequence of easing of fastening of covers коромысел on diesel engines

Removal

PERFORMANCE ORDER
1. Disconnect the battery from weight. Uncover the mechanism timing.
2. Ослабьте an inhaling of nuts of fastening of covers of platens коромысел. Nuts turn on gradually, since extreme covers.
3. Turn away a nut of covers of platens коромысел. Remove platens in gathering with коромыслами.
4. Remove from spring platens, коромысла and covers. Spread out details so that at assemblage to establish them on former places.
5. Check up palpation of the platen by means of prisms and стрелочного the indicator. Platen palpation in the central part should not exceed 0,4 mm, otherwise the platen replace. At the new platen palpation should not exceed 0,2 mm.
6. Check up a platen condition, at detection of obvious signs of deterioration the platen replace.

Installation

PERFORMANCE ORDER
1. Before assemblage grease platens, коромысла and cores of valves with pure oil for the engine. Establish the platen with большей in the length from outside final valves. Orientatsionnye labels on platens should be turned towards a forward part of the engine.
2. Tighten nuts of fastening of covers of platens with the moment 20–27 Н.м. At a tightening of nuts keep springs коромысел a key, breakage of springs otherwise is possible. An inhaling begin with the central nuts, being displaced to periphery. Nuts tighten gradually increasing efforts.
3. Adjust backlashes in valves. Establish a cover, start the engine and check up presence of leaks.

ENGINES V6

Details газораспределительного the mechanism in 6-cylinder engines

1 – nuts

2 – коромысла

3 – spherical prorates

4 – bars of pushers

5 – pushers

Removal and installation

PERFORMANCE ORDER
1. Disconnect the battery from weight.
2. Uncover the mechanism timing.
3. Turn away a nut, remove spherical prorates, коромысла and get bars of pushers. Spread out details so that at assemblage to establish them on former places.
The prevention

Bars of pushers of final and inlet valves have different length.


4. Establish bars of pushers on former places. Be convinced that the bottom end face of a bar has come into a pusher.
5. Grease rubbing surfaces коромысел and spherical prorates молибденовой with greasing of type Molykote or equivalent.
6. Wrap nuts коромысел and tighten them with the moment 20–27 Н.м.
7. Adjust backlashes in valves (see подразедл 3.1.5).
