Check
Gas-distributing belt
|
|
Do not allow hit on a surface of a gas-distributing belt of oils, lubricant or cooling liquid, - in case of need carefully remove the slightest traces of pollution. In order to avoid breaks, try not to bend excessively a tape of a belt, - the radius of a bend should not exceed 30 mm. |
|
|
|
1. Check a gear surface of a belt for existence of gaps, cracks and signs of wear of a tape. Turn a belt and attentively study a condition of its back.
2. In case of detection of defects the belt is subject to replacement. |
|
Natyazhitel of a belt
|
|
|
|
1. Check assembly of a natyazhitel for existence of signs of development of leaks through sealing rings. Estimate a condition and degree of wear of a rod of a natyazhitel. Replace defective components.
|
|
Existence on a surface of a rod of a natyazhitel of insignificant traces of lubricant is admissible. |
2. Holding assembly of a natyazhitel both hands, rest a rod against a floor or a wall of a garage and pressure him with effort 15 ÷ 50 kgfs, - if the rod begins to be buried in the assembly case, replace a natyazhitel. |
3. Measure rod vystupaniye size over the face surface of assembly. If the result of measurement exceeds the limit of the admissible range (15.4 ÷ 16.4 mm), replace a natyazhitel.
N = 15.4 ÷ 16.4 mm |

Installation of a natyazhitel of a belt and intermediate rollers
Fixing of a rod of a natyazhitel in the drowned situation
Press wring out a rod of a natyazhitel in the case before combination of lock openings. Record a rod in the drowned situation, having passed a metal core with a diameter about 1.5 mm throughout openings.
|
|
Watch that the effort was put strictly parallel to an axis of a rod and did not exceed value of 1 t! Before dumping pressure in the press, make sure of reliability of fixing of a rod a core. |
|
|
|

Inlet and final camshafts on DOHC engines at the taken-off gas-distributing belt can are turned independently from each other.
If at the same time there is a simultaneous movement of inlet and final valves, then they can be damaged as a result of contact with each other.
In view of told, at the taken-off belt it is necessary to fix all shaft in the provision of zero rise at which all valves are closed.
When at installation of a gas-distributing belt shaft are turned, inlet valves of the 2nd cylinder and final the 4th fall under the influence of the corresponding cams of camshafts of the left head of cylinders.
Camshafts of the right head of cylinders at the same time do not make impact on valves. At installation of a belt camshafts of the left head of cylinders have to be brought out of the provision of zero rise in a starting position by turning of their cogwheels on the minimum possible corner for the purpose of prevention of dangerous contact of valves. |
