Verifying and adjusting works on the car
THE GENERAL DATA

The description of the verifying and adjusting works spent on a forward suspension bracket is more low resulted.

CHECK OF DISORDER, LONGITUDINAL ANGLE OF SLOPE OF THE AXIS OF TURN, CONVERGENCE AND ROAD CLEARANCE

Before carrying out of any measuring works following conditions should be satisfied:

Deterioration of a profile of all tyres should be approximately identical.

Pressure in tyres should correspond to a car total load.

All wheel disks should be in a faultless condition.

Spherical support of steering draughts and a suspension bracket should not have backlashes.

The car should have the established road clearance (look the subsequent description).

At measurement of geometry of forward wheels the car should be on the equal platform having identical height around forward and back wheels. The difference in height more than 6 mm is not supposed. The fuel tank should be completely filled and the car should not be loaded something.

In the course of measurement the wheel should stand directly.

Measurement should be spent with application of optical devices. In the below-mentioned description cases of carrying out of measurements in emergencies are considered only.

ADJUSTMENT OF HEIGHT OF THE FORWARD SUSPENSION BRACKET (ROAD CLEARANCE)

The height of a forward suspension bracket is regulated by means of an adjusting bolt торсиона. The bolt arrangement is shown on an illustration. Bolt rotation clockwise increases suspension bracket height.

Adjusting bolt торсиона heights of a road gleam


The height, as shown is measured. The size "Z" is defined as a difference of the sizes "And" and "In". The received value is necessary for comparing to a preset value: the Maximum difference between both parties of cars of release from the middle of 1995 makes 5 mm.

ADJUSTMENT OF THE CORNER OF DISORDER OF WHEELS

The corner of disorder of wheels can be measured by means of mechanical means, however for exact measurement the optical device is required. If disorder leaves for the established values, it can be adjusted.

Adjustment is reached by change of a thickness of washers between an axis of the top lever of a suspension bracket and a cross-beam arm.

Adjusting washers have cuts. After отворачивания both bolts they can be taken out and replaced.
Disorder of cars should have the values specified in Specifications.
As much as possible admissible difference between the parties is specified in Specifications.

For adjustment turn away bolts and nuts of fastening of the lever of a suspension bracket and take out washers, as is shown in an illustration. Washers become on both bolts of fastening of an axis of the top lever. It is not necessary to confuse them to washers of adjustment of a longitudinal angle of slope of an axis of turn.

For reduction of disorder the quantity of washers increases, for increase accordingly decreases. It is necessary to remember that the general thickness of washers for adjustment of disorder and a longitudinal angle of slope should not exceed more than 10.8 mm.

After adjustment tighten nuts of fastening by the moment of 155 Nanometers, keeping bolts from проворачивания.
The adjustment control is made by optical means.

ADJUSTMENT OF THE LONGITUDINAL ANGLE OF SLOPE OF THE AXIS OF TURN OF THE WHEEL

The longitudinal angle of slope of an axis of turn is regulated by change of a thickness of a set of adjusting washers between an axis of the top lever of a suspension bracket and a cross-beam arm.

Washers are in a place shown on an illustration, over both fixing bolts.
Washers have a cut.

As well as the disorder corner, a longitudinal angle of slope of an axis of turn can be measured by mechanical means. However optical methods it is more preferable.

For adjustment of a longitudinal angle of slope of an axis of turn it is necessary to weaken bolts and the nuts shown on an illustration, and to remove or add adjusting washers.

Reduction of a longitudinal angle of slope of an axis of turn. At a forward bolt the quantity of washers increases or the quantity of washers at a back bolt decreases.

Increase in a longitudinal angle of slope of an axis of turn. At a forward bolt the quantity of washers decreases or the quantity of washers at a back bolt increases.
The difference in a thickness of washers of a forward and back bolt should not exceed 3.2 mm.

As washers for adjustment of a corner of disorder of wheels also are in a place shown on an illustration, the set of the washers which general thickness should not exceed 10.8 mm is formed.

After adjustment tighten болтовое connection by the moment of 155 Nanometers.

ADJUSTMENT OF THE CONVERGENCE OF WHEELS

The convergence of forward wheels is regulated by change of length of steering draughts on identical size. It provides preservation of position of spokes of a steering wheel. The distance between forward wheels Frontera ahead is less, than behind (to the middle 1995 releases) or are equal each other (from the middle of 1995 of release).

The scheme of installation of wheels is shown on an illustration.

Adjustment of a convergence of wheels by means of a special template is made as follows:

PERFORMANCE ORDER
1. Check up, that pressure in tyres corresponded established and that the car stood on an equal platform. The car should not have loading. The fuel tank should be filled.
2. Some times strongly press car edges in front that suspension bracket elements have occupied the working position.
3. A steering wheel put directly.
4. Establish a template "on a zero" and put it to a forward part of wheels at height of naves.
5. Put measuring cores of a template to edges of disks of wheels and clamp them.
6. Designate on wheels a chalk position of measuring cores.
7. Once again check up, that the template has been established "on a zero".
8. Move the car forward so that wheels have turned on a half-turn
And cretaceous strokes have appeared again at height of naves, but on the other hand wheels.
9. Put again a template to disks of wheels, but now under the car. If the template does not manage to be put to disks of wheels, it specifies that the size behind is necessary for increasing. The admission on the measured distance makes ± 2 mm.
10. Change position of measuring cores of a template so that it could enter between disks of wheels, clamp cores and take out a template to read the instrument. If the template indication leaves for the established limits, corresponding adjustment is required.
11. Lift and establish a forward part of the car on supports.
12. Ослабьте fastening of collars of both steering draughts
13. Turn out steering draughts from both parties on identical size. It is necessary to turn out in steps on a turn quarter.
14. Check up convergence adjustment as it has been described above and at achievement of desirable result tighten collars the moment of 120 Nanometers. It is necessary to watch that lengths of both steering draughts were identical. The difference in lengths should not exceed 5 mm.
15. After adjustment check up, that the steering wheel was on the average position. It is checked at car movement on direct road.

CHECK OF THE ANGLE OF ROTATION OF FORWARD WHEELS

The angle of rotation of forward wheels is checked after convergence adjustment. Over a finger of the spherical hinge of the bottom lever of a suspension bracket there is an adjusting bolt with which help the angle of rotation of forward wheels is regulated. For the control of an angle of rotation the graduated washer is required. Therefore considered work is recommended to be spent in the conditions of a repair truck. Thus it is necessary to mean that the angle of rotation of internal wheels makes 21°50 ' if the angle of rotation of external wheels is equal 20 °.
