4.2.1. Check of wheels
It will be required to you: manometer, pump, caliper.
Useful tips
Periodically check air pressure in tires (tab. 4.2). The increased or lowered pressure results in premature wear of tires, deterioration in controllability and stability of the car.
|
The table 4.2 Air Pressure in tires, kPa
We recommend to use the foot pump with the built-in manometer.
Fig. 4.1. Scheme of shift of wheels
|
In order that tires wore out evenly, through each 10 000 km of a run rearrange wheels according to the scheme in fig. 4.1.
Besides, through each 20 000 km of a run balance wheels and check the angles of installation of forward wheels. For this purpose address in a specialized workshop.
Preventions
You carry out all works on repair of wheels in specialized workshops.
Check that after repair the wheel was balanced.
Operation of tires with a worn-out protector can lead to accident.
|
1. Turn off a cap from the gate.
|
2. Check air pressure in the tire. For this purpose drop indications of the manometer on zero, having pressed the special button on the manometer case...
|
3.... connect the manometer to the gate and press a zolotnik a manometer tip.
|
4. If pressure is less than demanded, connect a hose tip to the gate...
|
5.... also pump up air, controlling pressure on the manometer.
|
6. If pressure is more than demanded, press a special ledge of the manometer on a tip of a zolotnik and let out the air from the tire. Measure the manometer pressure. Repeating these operations, bring pressure to norm.
|
7. If you noticed that air pressure in tires constantly falls, try to wrap more tightly a zolotnik by means of a cap with a key.
Prevention
In order to avoid pollution of zolotniks do not operate the car without protective caps. If caps were lost, surely establish new.
|
8. To check tightness of a zolotnik, wet a gate opening. If there were vials of the coming-out air, replace a zolotnik, having turned out faulty by means of a cap with a key.
|
9. Measure by a caliper the residual depth of a protector. If depth of a protector of 1,6 mm or is less, replace the tire.
|
10. If near at hand there is no caliper, then depth of a protector can be checked visually on indicators of wear of the tire in the form of continuous cross strips on a protector.
Note
The locations of indicators are marked on a tire sidewall with a triangle or the letters "TWI".

11. Check an inhaling of bolts of fastening of a wheel and if necessary tighten their moment 100–120 N · m.
