6.11. A camshaft

The note

Fig. 3.4–62. The klapannyj mechanism: 1 – the valve; 2 – a head of the block of cylinders; 3 – the valve of restriction of pressure 2,7 bar, 25 Нм; 4 – маслоотражательный a cap; 5 – a valve spring; 6 – a plate of a spring of the valve; 7 – crackers; 8 – a lever support; 9 – a sealing ring;
10 – a forward cover of the bearing of a camshaft of inlet valves; 11 – колпачковая a nut, 15 Нм; 12 – a bearing cover; 13 – a bolt, 10 Нм; 14 – a nut, 10 Нм; 15 – колпачковая a nut, 15 Нм; 16 – a back cover of the bearing of a camshaft of final valves; 17 – a camshaft of inlet valves; 18 – a camshaft of final valves; 19 – the lever; 20 – a hydraulic pusher; 21 – persistent half rings


Before installation it is necessary to grease working surfaces of hydraulic pushers 20 (fig. 3.4–62) with engine oil.

Removal
Before a detachment of the storage battery find out, whether there is at you a code of inclusion of a radio receiver.
Switch off ignition and disconnect a wire of "weight" from the storage battery.
Uncover heads of the block of cylinders.
Remove a gear belt from camshaft pulleys.

Fig. 3.4–55. An arrangement of bolts of fastening of a directing roller and a back casing of a gear belt



Unscrew bolts and remove back casings of a gear belt (fig. 3.4–55, 3.4–58 see).

Fig. 3.4–58. An arrangement of bolts of fastening of a back casing of a gear belt



Unscrew forward and back covers of bearings of a camshaft of inlet valves (fig. 3.4–62 see).

Fig. 3.4–63. An arrangement of nuts and bolts of fastening of covers of bearings of camshafts



Unscrew covers of bearings 0, 3, 4, 7 and 8 camshafts (fig. 3.4–63).
Gradually cross-wise unscrew covers of bearings 2 and 6 and remove a camshaft of final valves.
Gradually cross-wise unscrew covers of bearings 1 and 5 and remove a camshaft of inlet valves.

Installation
Be convinced that the cranked shaft is fixed by the adjusting screw 3242.
Unscrew from a head of the block of cylinders a hairpin located in an end face of a camshaft.
Be convinced that persistent half rings are on a place.
Check up a condition and position коромысел and hydraulic pushers.

Fig. 3.4–64. Use of the adaptation 3458 for correct installation of camshafts



Establish a camshaft of inlet valves into place so that in a shaft end face it was possible to establish the adaptation 3458 (fig. 3.4–64).
Establish covers of bearings 1 and 5 and fix their bolts.
Establish covers of bearings 2 and 6 and fix their bolts.
Establish covers of bearings 0, 3, 4, 7, 8 and fix their bolts.
Repeatedly check up position коромысел and hydraulic pushers.
Clear привалочные surfaces on a head of the block of cylinders and extreme covers of a camshaft.

Fig. 3.4–65. A place of drawing of a layer of hermetic on the right internal back cover



Put on привалочную a surface of the right internal back cover a thin layer of hermetic (fig. 3.4–65).

Fig. 3.4–66. A place of drawing of a layer of hermetic on an external back or forward right cover.



Put on an interfaced surface of an external back or forward right cover a thin layer of hermetic (fig. 3.4–66 see).
Establish external covers.
The further installation is spent to sequences, return to removal.
Establish a cover of a head of the block of cylinders.
Establish a gear belt.
Wait 30 minutes before engine start-up: hydraulic pushers should come to a normal state, otherwise pistons can hit about valves.
