Order of a poddomkrachivaniye of the car

Precautionary measures

  • Entering into a standard complete set of the car the jack is intended only for performance of replacement of wheels. At all do not perform any works under the car, fixed in the lifted situation by only one jack — apply special props.
  • For a podnimaniye of the car use a special jack entering into a regular complete set!
  • Get a jack only under special domkratny points!
  • Do not lift the car above, than it is really necessary for wheel replacement!
  • Do not enclose under a jack any subjects for the purpose of increase in its course!
  • Do not start the engine on the poddomkrachenny car — this requirement in a special measure belongs to the cars equipped with differential of limited sliding!
  • Passengers should not be in the poddomkrachenny car!


  1. At a poddomkrachivaniye of a front of the car plant on a jack head the special nozzle which was stored in a tool box — at a poddomkrachivaniye of a back of the car the nozzle is not required (see an illustration the Order of a poddomkrachivaniye of the car).
  2. Get a jack head under the corresponding domkratny point (see an illustration the Order of a poddomkrachivaniye of the car).

The heel of a jack should be established on an equal, firm site of a paving!

  1. Having hooked the suitable tool, remove a protective cover of a stupichny nut.

  1. Operating in strictly certain order, a ballonny key on 1-2 turns release nuts of fastening of a wheel.

The final otvorachivaniye of nuts should be made only after the wheel will be torn completely off from the earth!

  1. Firmly holding a jack a hand and rotating its collar, carefully lift the car so that the wheel completely came off the earth (take into consideration that fact that the spare wheel, unlike failed, will be pumped up and will demand a little bigger free space for installation).
  2. Finally unscrew wheel nuts and remove a wheel.
  3. Clear a surface of a nave interfaced to a rim of dirt.
  4. Establish a spare wheel and fix it wheel nuts, having by hand tightened the last.

Nuts should well up in dry, without application of any oils or greasings!

  1. Evenly delay nuts of fastening of a wheel a ballonny key.
  1. Accurately lower the car on the earth and, operating in strictly certain order, strongly tighten wheel nuts. At the first possibility make correction of effort of a tightening of nuts with application of a dinamometrichesky key — demanded value makes 118 — 147 Nanometers.
