Removal and installation of covers of drive ГРМ

The general information

Elements of drive ГРМ are concluded in space between two, forming the closed casing, covers: forward and back. Both covers are made of an aluminium alloy by a moulding method. The two-section design of a casing allows to lower level of the noise background made at functioning of a chain drive.

In quality прокладочных materials between the block of the engine and a back cover of drive ГРМ sealing rings, a metal lining and hermetic are used. Hermetic between forward and back covers is used for prevention of leaks of oil.

On a joint of a cranked shaft from forward cover ГРМ it is established фторполимерный [фторуглеродный?] an epiploon.

Details of installation of covers of drive ГРМ are presented on an illustration.

The sizes of bolts of fastening of a forward cover of drive ГРМ

The sizes of bolts:

A: 6 x 45
B: 6 x 16

C: 6 x 30
D: 6 x 50

* The bolt marked with an asterisk is established with a sealing washer

 PERFORMANCE ORDER

1. Remove a pulley of a cranked shaft (see Has undressed Removal and installation of a pulley of a cranked shaft).
2. Remove a forward cover of drive ГРМ.

 For fastening of a cover of drive ГРМ bolts of four types are used, - in order to avoid mess at уке spread out разноразмерные bolts separately.

INSTALLATION

 PERFORMANCE ORDER

1. Examine a cover on presence of cracks and other mechanical damages.
2. Check up an interfaced surface of a cover and a point of fastening of a pulley of a cranked shaft on presence of signs of development of leaks of oil.
3. A defective cover replace.
4. Carefully smooth out an interfaced surface of a cover, completely having removed from it traces of a material of old hermetic, then wipe a surface the rags moistened in acetone.

5. Impose on an interfaced surface a pillow of hermetic of type Three Bond 1280В in diameter 2.50.5 mm in section, - track, that hermetic was imposed from the inside from болтовых apertures.


6. Establish a forward cover of drive ГРМ and temporarily tighten bolts of its fastening.

 Roll bolts strictly on the former places.


7. Operating strictly in a certain order, tighten fixing bolts with demanded effort (6.6 Nanometers).


8. Establish a pulley of a cranked shaft (see Has undressed Removal and installation of a pulley of a cranked shaft).

Back cover

REMOVAL

 PERFORMANCE ORDER

1. Remove a pulley of a cranked shaft (see Has undressed Removal and installation of a pulley of a cranked shaft).
2. Remove a forward cover of drive ГРМ (the previous subsection see).
3. Remove газораспределительную a chain (see Has undressed Removal and installation газораспределительных chains).
4. Remove asterisks of a drive of camshafts (see Has undressed Removal and installation of asterisks of a drive of camshafts).

5. Remove an asterisk of a cranked shaft () and the oil pump ().

6. Remove the case редукционного the valve of the oil pump.

The sizes of bolts:
1 and 5 6 x 26
2-4 and 9 6 x 35
6-8 and 10 6 x 16

7. Remove the water pump.

 At occurrence of difficulties screw two bolts М8 in диагонально the located carving apertures (), - the uniform serial tightening of bolts should help branch of pump assemblage from a back cover of drive ГРМ.

8. Turn out fixing bolts and remove a back cover of drive ГРМ. The remark: For fastening of a cover of drive ГРМ bolts of seven types are used, - in order to avoid mess at installation spread out разноразмерные bolts separately.

The sizes of bolts:
A: 6 x 14
B: 6 x 18 (silvery)
C: 6 x 30
D: 6 x 18
E: 9 x 40
F: 6 x 30
G: 6 x 22
