14.13. Check and adjustment of a tension of poliklinovy belts
|
|
|
|
1. Check a condition of a poliklinovy belt and its arrangement on pulleys.
|
|
Check correctness of an arrangement of edges of a poliklinovy belt in flutes of pulleys.
If at work poliklinovy the belt publishes extraneous noise, check a belt on lack of wear and damages, and also working surfaces of pulleys. Also check the deflection of a belt defining its tension.
|
|
2. By the special device measure a tension of a driving belt. In the absence of the special device check a belt tension, having pressed on it effort of 100 N in a place located on identical removal from pulleys and measure a belt deflection.

The tension of a belt is regulated automatically by the tension mechanism.
|
|
The tension of a belt should be measured precisely on the center between pulleys. |
When the new belt is established, regulate a tension to the average value given in the column "New".
The belt which was in the use considered the belt which has worked on the engine more than 5 mines and its tension it is necessary to regulate to the average value given in a column
At adjustment of a tension of the belt which was in the use or the belt which has worked on the engine more than 5 mines it is necessary to regulate its tension to the average value given in a column "Being in the use".
At periodic surveys it is necessary to be guided by the column "Check".
Adjustment
DOHC engine of 2,0/2,4 l
|
|
| 1. Weaken a bolt of "A" of fixing of a bolt of adjustment of a tension.
2. Rotating an adjusting bolt of "B", adjust a belt tension.
3. Tighten a bolt "And" fixings of a bolt of adjustment of a tension.
|
|
4. Check a tension of a belt and, if necessary, repeat adjustment.
|
|
Before repeated check of a tension of a belt, turn on some turns a cranked shaft of the engine.

|
|
1. If the indicator of the mechanism of a tension of a belt leaves for a label of the maximum tension, replace a driving belt.
|
|
2. At replacement of a driving belt, the indicator of the mechanism of a tension should be between MAX and MIN labels. Tension measurement by the special device of type A
- At measurement of a tension of a poliklinovy belt the device should not concern other elements of the engine.
|
|
|
Tension measurement by the special device of type B
- At measurement be convinced that turned the button of repeated installation in the arrow direction to establish an arrow of the device in an initial condition.
- After removal of the device from a belt of the shooter of the device will still specify a belt tension.
