To check
|
|
Do not allow to be bent and to be twisted, a belt of GRM drive, and also hit him of oil, OZh and fuel. Do not use a natyazhitel of a belt to fix defendant with crank or the axle of a provorachivaniye holding tight pins of the fixation of cog-wheels. A provorachivaniye of the end does not allow in the tuck - of the belt of GRM drive any more than for several degrees of the combination of teeths. |
|
|
|
|
-
Check a condition of the belt GRM that is taken away of the motor. The full or partial loss of teeths can lead to the axles interference.
|
- In the moment of identification of slits or signs of perceptible use of the exterior side of a check of belt surfaces of work of intermediary rolls and a roll of the water bomb of existence of zadir and agnails.
- I use it unilateral of a belt it will happen, check a condition of the plate of direction and follow the trace of the fairness of the combination of cog-wheels and intermediary rolls.
- The substitution of a belt has to be done according to the Time-table of the regular maintenance of the car (to see the Chief Nastroyki and the regular maintenance of the car). The belt that is in a doubtful state is subject to the substitution without fail. Before the installation of a new belt they try to reveal and to liquidate all the reasons that led to the premature failure of an old man.
|
|
It is recommended drive does the substitution of a belt of GRM every time after his removal. |
- The intermediary's fighter videos and manually they check the tranquillity and the smoothness of the rotation of his loads. One secures of the lack of a play of excessive side. If necessary it substitutes rolls.
- Visually check the consolidation of rolls and a natyazhitel of the existence of the hole of oil. If necessary rolls or a natyazhitel substitutes.
|
|
Consolidations of an intermediary roll
|
|
|
Consolidations of a natyazhitel
|
|
|
The existence of a fine aspect of oil in an internal edge of the consolidation is allowed. |
- When a natyazhitel is maintaining both hands in horizontal position, rest an empurrador against a firm surface and a natyazhitel continues – the empurrador must not move. If the empurrador utaplivatsya, substitutes a natyazhitel.
|
|
A press empurrador does not maintain a natyazhitel down. |
- Edge size of empurrador of measure of the case of a natyazhitel of a belt of GRM drive. If the received value is not in the 10,0 10,8 mm variety ÷, substitute a natyazhitel.
|
|
Installation
|
|
- Drive compensates for the superficial plans of GRM what are in the area of dirt and oil. Rub with acetone cog-wheels and do not dirty them in the installation time.
- Having developed correctly a cog-wheel about a spline, put link in a pin of an end of inclination rotor of CKP to the motor. Try not to damage a garland of gear of a rotor of CKP. make sure of the fairness of the combination of etiquettes of VMT in a wheel and the case of the bomb of oil, soon establish the plate of property of a cog-wheel and hold tight a pin of his fixation with the effort of 8 nanômetros.
- Establish intermediary rolls and hold tight pins of his fixation with the necessary efforts.
|
|
During the installation of an intermediary roll they polish a part of woodcarving of a pin of his fixation with the selante of fixation Loctite 242, and also they do not forget of establishing a lavador of the form of plate. After the installation of intermediary rolls they check the smoothness of his rotation. |
- Having developed correctly cog-wheels about splines, they put us in axles pins according to the etiquettes put in the removal. Hold tight pins of the fixation of cog-wheels of axles with the necessary efforts, maintaining pulleys of a provorachivaniye through the special adaptation.
- One secures that the doubled cog-wheels and axles are in the provisions that correspond to VMT of the piston of the first cylinder in the end of a step of compression.
- There establishes a belt of GRM drive so that the etiquettes in him coincided with reciprocal etiquettes.
- Drown an empurrador in case of a natyazhitel with a force of 981 ÷ of 9807 N (100 ÷ 1000 kgfs) and register it in this situation, having passed, for example, a key of six sides prutkovy of 1,27 mm through openings in case of a natyazhitel and in an empurrador. Establish a boot of a natyazhitel.
- Establish a natyazhitel and hold tight pins of his fixation in the beginning to the hand, and soon it is consecutive, with the effort of 27 nanômetros. Take away a key prutkovy, having launched an empurrador.
- Become an end of inclination in two whole revolutions and one secures that the piston of the first cylinder is in the end of a step of the compression.
- Establish the right basic arm of the motor and hold tight a pin of his fixation with the effort of 28 nanômetros.

There examines the placing of a covering n ° 2 of a belt of GRM drive. If the entirety of the placing is broken, substitute it, previously having withdrawn all the aspects of the old placing and having compensated for a surface of covering. Withdraw a protective movie or paper of the new placing, establish the placing exactly in the appropriate covering outline and strongly hold tight the placing to a covering. One secures that the placing supported a covering.
|
- There establishes a covering n ° 2 of a belt of GRM drive and hold tight 5 pins of his fixation with the effort of 8,5 nanômetros.
- There establishes a protector of braid of electrical system of motor in a covering of belt of GRM drive n ° 3.
- There establishes a guide of belt of GRM drive of the party in the form of cup on the outside.
|
|
-
There examines the placing of a covering n ° 1 of a belt of GRM drive. If the entirety of the placing is broken, 2 substitutes it similar to the placing of a covering n °.
