1.6.3. Wheel replacement

GENERAL INFORMATION

Prevention

If at you lowered a wheel, move down after the journey on safe distance. Muffle the engine, include headlights of the alarm system and establish other warning signs for the prevention of other drivers.

At a car raising by means of a jack passengers should leave the car.

Check, that passengers expected at safe distance from the car and traffic.

Before wheel replacement, check, that the earth was equal and firm. If it is necessary, put under a jack a board.

The car is not insured from movement when one wheel does not concern the earth if you simply include parking transfer on an automatic transmission or include any transfer on a mechanical transmission. To guarantee that the car will not come unexpectedly to movement and will not slide off a jack, always establish the car on the hand brake and block diagonalno the located wheels of the car at wheel replacement.


Step 1

Get a jack, tools and a spare wheel from a luggage carrier.

Step 2

Remove a decorative cap (if it is established) wheel naves by means of a screw-driver (establish a flat edge of a screw-driver for edge of a cap and wring out it) or remove a big decorative cap (if is established), having inserted fingers into openings of a cap and having removed it.

Step 3

Turn off all bolts of fastening of a wheel counter-clockwise on one turn by means of a face wrench. Yet do not remove bolts.

Step 4

On the bottom, on each party of the car is on two reference points which are located slightly below rectangular points on a car body.

These deepenings are located approximately in 10 cm from forward and back wings.


On the Audi-Kupe and Quattro models these deepenings are located approximately in 12 cm from a forward wing and approximately in 6 cm from the back.

Prevention

Poddomkrachivaniye of the car in any other points can damage the car and lead to traumas.

Provide a firm support for a jack on the earth. If it is necessary, put under a jack a board.


Reliably establish a jack under the reference point closest to that wheel which it is necessary to replace.

Establish an elevating shoulder of a jack and check, that the crest under the car bottom reliably entered into a groove on an elevating shoulder so that the jack did not slide off.


Adjust a jack so that its basis was under edge of the car and reliably stood on the earth.


Step 5

Prevention

Do not lift the car while you are not sure that the jack is reliably established.

At a car poddomkrachivaniye passengers should not is in salon.


For a car raising, rotate the handle clockwise.

Lift the car only on such height which is necessary for wheel replacement.

Step 6

Only for cars with disks of wheels of the Speed Line series:

Before a car poddomkrachivaniye, remove a cap of a nave of a wheel (it is specified by an arrow) by means of a screw-driver.

Step 7

Turn off a bolt of fastening of the wheel, the next to top, by means of the handle of a screw-driver and put it on a pure surface (for example, a paper towel).

Twirl on its place a plastic pin.

Then completely turn off other bolts of fastening of a wheel and remove a wheel, having left a plastic pin in an opening for a bolt.

Before installation of a new wheel, clean off dirt or the traces of corrosion which are available on adjoining surfaces of a wheel or a nave.

Establish a new wheel and press it to a nave. The plastic pin guarantees that openings in a wheel will coincide with carving openings in a wheel nave.

Establish bolts of fastening of a wheel by means of the screw-driver handle. Then unscrew a plastic pin and insert a remaining fixing bolt.

Tighten a few all bolts by means of a face wrench.

Bolts of fastening of a wheel should be pure and easy rotate - never grease them.


Prevention

The handle of a screw-driver should not be used for an inhaling of bolts of fastening of a wheel.


To lower the car, rotate the handle counter-clockwise while, the jack completely not to fall.

Step 8

Then, diagonalno, reliably tighten all bolts by means of a face wrench.

It is very important to twirl fixing bolts till the demanded moment of an inhaling.

Bolts are twirled correctly if their moment of an inhaling is equal 110 N of m. Any person of average force can twirl them till such moment of an inhaling. If you doubt that bolts till the demanded moment of an inhaling twirled, check it by means of a dinamometrichesky key.

If you notice that bolts of fastening rusted and badly twist, replace them.

While you do not replace bolts, go carefully.

Step 9

Completely lower the car on the earth and remove a jack.

Check pressure in the tire of just established wheel.

Reliably fix the damaged wheel, a jack and tools in a luggage carrier.


Prevention

Do not postpone repair or replacement of the lowered wheel by long term.

Do not forget that the small-sized spare wheel is intended only for temporary use!
