2.10.8. Correction of phases of gas distributionIf a nave In
it was not recorded, weaken fixing bolts 2 gear wheels of an inlet cam-shaft (fig. 2.497). Take a wrench the central bolt of an inlet cam-shaft.
Turn a nave so that it was possible pass a lock pin.
Tighten bolts 2 gear wheels of an inlet cam-shaft with effort of 25 N · m.
Remove lock pins and a stopper of the crankshaft.

ATTENTION
It is allowed to scroll the engine only for the crankshaft in the direction of rotation (clockwise).
|
Make two turns of the crankshaft in the direction of rotation of a shaft of the engine until the crankshaft rises in the provision of a dead point again.
Carry out repeated control of phases of distribution.
If it is impossible to fix the crankshaft, weaken bolts of 1 and 2 gear wheels And yes In cam-shafts (fig. 2.497). Turn the crankshaft in the direction of rotation of the engine a little so that the crankshaft it was possible record a crankshaft stopper for engines with a round gear wheel of a gear belt of the crankshaft or by means of a crankshaft stopper for engines with an oval gear wheel of a gear belt of the crankshaft.

NOTE
If the crankshaft was turned for VMT, it is necessary to turn at first slightly it back that then anew to establish in VMT in the direction of rotation of the engine.
|
Tighten bolts of 1 and 2 gear wheels And yes In cam-shafts with the moment of 25 N · m (fig. 2.497). Remove lock pins and a stopper of the crankshaft.

ATTENTION
It is allowed to scroll the engine only for the crankshaft in the direction of rotation (clockwise).

Make two turns of the crankshaft in the direction of rotation of a shaft of the engine until the crankshaft rises in the provision of a dead point again.
Carry out repeated control of phases of distribution.
Assembly
Further assembly is carried out in the return sequence.
Establish the lower and middle part of the protection cover of a gear belt.
Establish a quencher of tortional fluctuations.
Establish poliklinovy a belt.
Establish a radiator frame with hinged elements.
Lower an emphasis of a forward support at the expense of a body weight on the rubber buffer and tighten nuts.
Establish an overlay of a front bumper.
Inhaling moments
Tension roller of a gear belt and head of the block of cylinders: 20 N · m +45 ° *.
Asterisk of a cam-shaft and nave: 25 N · m.
The lower cover of a gear belt to the block of cylinders: 10 N · m **.
Average cover of a gear belt to the block of cylinders: 10 N · m **.
Emphasis of a forward support to a radiator frame: 28 N · m.
Hose collars, width are 9 mm: 3 N · m.
Hose collars, width are 13 mm: 5,5 N · m.
* 45 ° correspond one eighth turns.
** To insert bolts, previously having greased them with a carving varnish.
