Do not suppose hit on a surface газораспределительного a belt of oils, greasing or a cooling liquid, - in case of need carefully remove the slightest traces of pollution. In order to avoid breaks, try not to bend excessively a belt tape, - the bend radius should not exceed 30 mm. |
|
|
|
1. Check up a gear surface of a belt on presence of ruptures, cracks and signs of deterioration of a tape. Turn a belt and attentively study a condition of its back party.
2. In case of revealing of defects the belt is subject to replacement. |

|
1. Check up assemblage натяжителя on presence of signs of development of leaks through sealing rings. Estimate a condition and degree of deterioration of a rod натяжителя. Replace defective components.
|
|
Presence on a rod surface натяжителя insignificant traces of greasing is admissible. |
2. Keeping assemblage натяжителя both hands, rest a rod against a floor or a wall of garage and press on it with effort 15 50 кГс, - if the rod begins заглубляться in the assemblage case, replace натяжитель. |
3. Measure size выступания a rod over a face surface of assemblage. If the result of measurement falls outside the limits an admissible range (15.4 16.4 mm), replace натяжитель.
Н = 15.4 16.4 mm |

Installation натяжителя a belt and intermediate rollers
Rod fixing натяжителя in the drowned position
Press wring out a rod натяжителя in the case before combination of lock apertures. Fix a rod in the drowned position, having passed in apertures a metal core in diameter about 1.5 mm.
|
|
Watch, that the effort was put strictly in parallel an axis of a rod and did not exceed value 1 т! Before to dump pressure in a press, make sure of reliability of fixing of a rod a core. |
|
|
|
1. Establish натяжитель on the regular place, shift it to the right against the stop and temporarily fix.

| 1. The help of the special tool, develop cogwheels cranked and both camshafts adjusting labels upwards. |
|
2. Having achieved combination of the labels put on the back party of a belt with adjusting labels, accurately put on a belt cogwheels, - track observance of an initial direction of rotation of a belt.
3. Establish an intermediate cogwheel № 2.
4. Establish an intermediate roller.
5. Release fastening bolts натяжителя, displace assemblage of the last against the stop to the left, then again tighten bolts.
6. Once again make sure of correctness of combination of labels of a belt then take the core keeping a rod натяжителя in drowned position.

Inlet and final camshafts on engines DOHC at removed газораспределительном a belt can are turned independently from each other.
If thus there will be a simultaneous moving of inlet and final valves they can appear are damaged as a result of contact with each other.
In view of told, at the removed belt it is necessary to fix all shaft in position of zero lifting at which all valves are closed.
When at installation газораспределительного a belt shaft are turned, inlet valves of 2nd cylinder and final 4th fall under the influence of corresponding cams of camshafts of the left head of cylinders.
Camshafts of the right head of cylinders thus do not render influence on valves. At installation of a belt camshafts of the left head of cylinders should be deduced from position of zero lifting in a starting position by поворачивания their cogwheels on the minimum possible corner for the purpose of prevention of dangerous contact of valves. |
