2
Put the Jack on the installation place closer to the wheel, which are going to remove. Slightly lift the machine until the load on the Jack.
Cylinder key start to Unscrew the bolts, turning them into ½ - 1 turn.


3
Raise the car Jack until a level when between the wheel and the surface where there is car, there will be free space of 3-5cm. then Unscrew all the wheel bolts to the end. Take the wheel off.

4
Not always work runs smoothly, sometimes there are unforeseen difficulties – the wheel bolts do not get loose. Reasons for this may be several:

  • excessive tightening of the bolts when installing the wheels;

Reception two: heat the bolts. Better to do it with a gas burner. Prostatite to heat the bolt with a hammer. Heated the bolts try to twist.
Reception three: when everything is tested, and the bolt remains in place, and the head of his already badly injured, weld it to a piece of pipe or a nut of larger diameter.

7
If there is a need to change a tire during the trip (puncture of the camera, puncture tires, etc.), and the wheel bolts are not unscrewed, there are 2 ways to get out of this situation without serious losses:

Advice 3: How to Unscrew stripped nut

Repair of equipment, machines and mechanisms used in suburban areas is a regular job of loosening and tightening screws, bolts and nuts. In some cases fasteners are so much "stuck" in their position that disconnect them in the traditional way is very difficult. To remove the stripped nut, you will have to use some wisdom.
How to Unscrew stripped nut
You will need
  • - metal brush;
  • - liquid WD-40;
  • - compression key;
  • - the wrench;
  • - chisel;
  • - a hammer.
Instruction
1

2
First, clear the protruding end of the threaded connections with a wire brush. Then apply to place the thread in a few drops of kerosene or, even better, a special liquid WD-40. Wait 10-15 minutes or even a little more, and then try again to Unscrew the nut. Best use is not regular open-end wrench, and a cap.
3
If the nut and now can not be, try to make the inverse effect, i.e. make attempt to loosely install the nut, not loosen it. In most cases, these steps allow you to remove the fastener, not bringing work to deal with stripped threads or damaged faces of the nut.
4
If the flange nut was damaged, use for loosening again, a swivel key or a detachable head. Lightly knock the nut with a hammer, trying not to make too strong attacks.
5
If no results, use an adjustable wrench or small vise. Wrap the jaws of the instrument around the deformed nut and rotate first in the direction of nut tightening, and then in the opposite direction.
6
In a particularly complex case, use for unscrewing stripped nut chisel and hammer. Put the chisel to the nut at a slight angle and gently punches try to move the fastener in the direction of loosening (counter-clockwise).
7
If none of the methods can move the nut with the space, it is necessary to take extreme measures: cut nut strong hammer blows on the chisel to split it apart. In this case, it is likely you will be able to separate the connection, but then have to change the whole mounting (nut and bolt).
