1.6. Poddomkrachivaniye / posting and emergency transportation of the car

Poddomkrachivaniye by means of regular and podkatny jacks, wheel replacement

The regular jack is intended only for short-term lifting of the car at wheel replacement; before performance of any works under the car it is necessary to establish it on special props.


 PERFORMANCE ORDER

  1. Park the car on an equal horizontal platform, whenever possible with a firm covering.
  2. Cock the parking brake and establish the AT selector lever in the situation "P" (on models from AT) or include the first or reverse gear (on models from RKPP).
  3. In case of need turn on the alarm system and expose a sign of an emergency stop.
  4. Prop up protivootkatny boots a wheel located on a diagonals from a subject to replacement.

At procedure performance on a bias it is necessary to enclose boots under both wheels of a serviceable axis from descent.

  1. Prepare a jack, a key and a spare wheel. At the corresponding complete set remove a protective cap of a disk, then give on one turn bolts of fastening of the failed wheel. If necessary unblock bolts with locks in a head for what remove from a head a protective cap, insert a key parallel to oval dredging and turn it on a turn quarter. Get a jack head under the corresponding point under a threshold beam – track, that the jack settled down strictly vertically, and his heel rested all the surface against soil, – at friable soil enclose under a heel a suitable lining (in the winter it is useful to have a piece of a wide board in the car).

  1. Watch as well that the head of a jack entered into rectangular deepening on the car bottom.

Regardless of bias existence the jack always should occupy strictly vertical situation!

  1. Working with the jack handle, raise the car, – the damaged wheel should come off the earth completely.
  2. Completely give wheel bolts and make wheel replacement.
  3. Check pressure of a rating of the established wheel, in case of need make the corresponding adjustment (see. Specifications to Head Governing bodies and operation receptions).
  4. Clean the removed wheel and the tool on the regular places.
  5. In summary evenly tighten wheel nuts in some approaches in a diagonal order with effort about 100 Nanometers.

Car posting

It is not authorized by no means опирать the car on the power unit, forward and back suspension brackets since thus specified designs can be seriously damaged.

For posting of the car use a platform or the lift with four paws resting against domkratny points.

Transportation of the emergency car

Transportation on a wrecker platform

It is most reasonable to transport the emergency car on the wrecker. Such transportation can be made:

  • Method of complete loading of the faulty car on a wrecker platform;
  • Method of partial loading (one axis on the pendant shelf of the wrecker, and another or on the special cart, or on the earth).

Preparation for towage

Demountable eyes for fastening of a towing cable are rolled in the openings located under caps on the right side of each bumper. For a vvorachivaniye of eyes it is convenient to use a key for wheel nuts.

Before the towage beginning on the emergency car it is necessary to include ignition, to establish transmission in neutral situation and to release the parking brake.

It is most reasonable to make towage on a rigid hitch. At towage on a flexible hitch use only elastic cable specially intended for this purpose.

Before a start of motion drivers of both vehicles (towing and towed) should coordinate among themselves a route.

Towage for the purpose of engine start

 PERFORMANCE ORDER

Previously try to start the engine from the auxiliary battery (see below). Start of the engine of models with AT a method of towage or pushing is not possible, and on models from RKPP thus it is possible to damage the catalytic converter – the towage distance for the purpose of start of the engine should not exceed 50 m.

  1. Include the 2nd or 3rd transfer, squeeze out a pedal of coupling and, holding it, include ignition.
  2. When both cars will move, slowly include coupling (release a pedal).
  3. As soon as the engine will be started, squeeze out a pedal of coupling and switch off transfer not to face the towing car.

Towage of the emergency car

Car towage without oil in transmission, and also at malfunction of AT is not admissible without a separation of driving wheels from the earth.

The driver of the towing car should try to move as much as possible evenly, smoothly releasing coupling at gear shifting and, especially, at a troganiye from a place.

At management of a towed vehicle watch, that during movement the cable constantly remained tense, try not to allow sharp breakthroughs and arrivals on a proslablenny cable.

Remember that at the switched-off engine efficiency of braking of the car considerably decreases because the vacuum amplifier of brakes ceases to function. Thus it is necessary to squeeze out a pedal of a working brake with much big, than usually, effort; at maneuvering performance the bigger effort should be put also to a steering wheel since the amplifier of a steering also will not function.

Movement should be carried out on the shortest route. The faulty car with AT is authorized to tow with a speed no more than 70 km/h and on distance no more than 150 km. Observe traffic regulations, avoid sharp braking, accelerations and superfluous maneuvering. Remember that at car towage on edge of a dirt road always there is a danger of demolition on a roadside.

Before the beginning of towage of the faulty car with AT check level of transmission liquid (see. Head of Control and routine maintenance of the car), – at insufficient level of ATF, it is necessary to modify it, or to tow the car only with the driving wheels torn off from the earth.
