Car poddomkrachivaniye order

Precautionary measures

  • The jack which is included in a basic equipment of the car is intended only for performance of replacement of wheels. Do not perform any works under the car, the lifted situation recorded in as only one jack at all — apply special props.
  • For lifting of the car use the special, being included in the regular package jack!
  • Get a jack only under special domkratny points!
  • Do not lift the car above, than it is really necessary for replacement of a wheel!
  • Do not enclose under a jack any objects 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 put the special nozzle which is stored in a toolbox on a jack head — at a car back poddomkrachivaniye the nozzle is not required (see the illustration Car Poddomkrachivaniye Order).
  2. Get a jack head under the corresponding domkratny point (see the illustration Car Poddomkrachivaniye Order).

The heel of a jack has to be established on the flat, firm site of a paving!

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

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

The final otvorachivaniye of nuts should be made only after the wheel is 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 the fact that the spare wheel, unlike failed, will be pumped up into account and will demand a little bigger free space for installation).
  2. Finally turn off wheel nuts and remove a wheel.
  3. Clear the nave surface interfaced to a rim of dirt.
  4. Establish a spare wheel and record it wheel nuts, having by hand tightened the last.

Nuts have to well up in dry, without use of any oils or lubricants!

  1. Evenly delay nuts of fastening of a wheel a balloon key.
  1. Accurately lower the car on the earth and, working in strictly certain order, strongly tighten wheel nuts. At the first opportunity make correction of effort of tightening of nuts with application of a dynamometer key — the required value makes 118 — 147 Nanometers.

Use of nuts of the wrong standard size, as well as violation of an order and effort of their tightening is accompanied by risk of weakening of fastening of a wheel and is fraught with the most serious consequences! After 1000 kilometers of a run it is necessary to make retightening of wheel nuts.

  1. Strongly fix the removed wheel on the regular place and remove into place a jack and a toolbox. Track reliability of fixing of all components — the effort of tightening of a nut of fastening of a wheel to the bottom of the car makes about 66 — 89 Nanometers.

Before beginning the movement make sure of correctness of pressure of a rating of the established spare wheel — remember that the wheel will be cold! Demanded value of pressure of a rating of cold wheels it is given in Schild, fixed on a cover of the main ware box.

Wheels are considered cold not less than three hours later after end of a trip, or after passing of distance no more than 1.6 km.
