Adjusting the installation angles and convergence of the front wheels GAZ-3110

It is recommended to adjust the wheel alignment angles at the stand at service stations. Adjustment should be made in the following sequence:

  • - camber adjustment;
  • - adjustment of the longitudinal inclination of the kingpin;
  • - wheel alignment adjustment.

Front wheel alignment:

  • – camber 0°±30'
  • – the difference in camber values ​​for the right and left wheels is not more than 30'
  • – tilt of the lower end of the kingpin forward from 4°30' to 6° (from 5° to 6°30')**
  • – the difference in the kingpin inclination values ​​for the right and left wheels is not more than 30'

**The value of the caster angle of the kingpin for the gross vehicle weight (for reference). Load - 5 people or a load of 150 kg in the front and 225 kg in the rear seats.

Toe-in:

  • - when measured on tires 1-2 mm (7'-14')
  • - when measured on rims 0.7-1.3 mm
  • - the largest angle of rotation of the inner front wheel (not adjustable) 40°-42°

Adjustment is carried out with securely fixed pendulum lever, steering mechanism, steering linkage, upper and lower front suspension arms, adjusted front wheel hub bearings, serviceable front suspension and steering linkage, normal tire pressure.

When checking the corners, the wheels of the car must be in a straight-line position.

Adjustment of the angles of installation and convergence of the front wheels of the GAZ-3110

Camber and caster adjustment is carried out by changing the number of shims 3. Changing the equal number of shims in the front and rear mounting of the upper arm axle changes the wheel camber.

One 1.0mm shim changes camber by approximately 0°12'

Adjustment of the longitudinal inclination of the kingpin is carried out by changing the number of spacers 3 only in the front or rear mounting of the upper arm axle.

One shim changes kingpin tilt by approximately 0°25'

To adjust the angles, loosen nut 2 and bolt 1, select the required number of spacers 3, tighten bolts 1 and then nuts 2 to 44-56 Nm (4.4-5.6 kg/cm).

Adjusting the toe-in of the front wheels is carried out by turning the adjusting tubes of the side steering rods.

Adjustment on the outer side surfaces of the tires is carried out on the stand.

Before adjusting, you need to find the points of equal lateral runout of the tires and turn the wheels so that they are located in a horizontal plane.

Adjusting the angles of installation and convergence of the front wheels of the GAZ-3110

If during straight-line movement the steering wheel occupied the correct position (the steering wheel spokes were located horizontally), and the toe-in value differed from the nominal value by no more than 3-4 mm, then the toe-in can be adjusted by changing the length of any side link.

To do this, loosen the bolts 3 of the clamps 4.

Then turn the adjusting tube 2 using the barb 1 until the convergence value corresponds to the nominal value.

Turn the clamps 4 so that the ears of the clamps are directed in one direction and lie in the same plane.

Tighten bolts 3 to 15-18 Nm (1.5-1.8 kg/cm).

If before adjusting the steering rods were disassembled with a change in their length, adjust the convergence in the following order:

  • - set the steering wheel to the straight ahead position (wheel spokes are horizontal);
  • - set the left wheel to the straight ahead position by turning the left adjusting tube;
  • - adjust the convergence by turning the right adjusting tube;
  • - turn the clamps of the adjusting tubes so that the ears of the clamps are directed in one direction and lie in the same plane, and tighten the bolts to a torque of 15-18 Nm (1.5-1.8 kg/cm).

An old-fashioned way to check and set angles

Gross violations in the corners of the installation can be determined using improvised means (caliper and plumb bob)

The adjustment sequence is as follows:

  • - adjust the camber of the front wheels;
  • - kingpin pitch angle;
  • - wheel alignment.

It is difficult to measure the angle of the kingpin with the required accuracy without special equipment, so we recommend not changing the factory settings (but keep the difference in the thickness of the gaskets of the front and rear fastenings of the upper arm axle).

Before adjusting, we check:

- play in the front suspension, wheel bearings and steering; tire pressure. We find points of equal lateral runout of the tires and rims of the front wheels, marking them with chalk.

We install the car on a horizontal platform - the wheels are straight.

Camber adjustment

GAZ wheel alignment -3110

Set the front wheels so that their equal lateral runout points are vertical.< /p>

On the front fender of the car, in the center of the wheel, we hang a plumb line.

We lower the weight of the plumb line into a container with oil, while it should not touch the bottom.

We measure the distance from the wheel rim to the plumb line at the lowest point

Measuring the distance from the wheel rim to the cord at the top

Repeat the measurements for the second wheel. camber (the difference between the distances to the upper and lower points) should be 0 ± 3.5 mm.

If necessary, loosen the nuts and bolts of the upper arm axle and select shims to obtain the required camber.

In order not to disturb the longitudinal inclination of the kingpin, we add or remove the same number of spacers from the front and rear axle mounts.

Adding 1mm thick shims increases camber by approximately 1.2mm.

Toe adjustment

Install the wheels so that 2 points of equal runout on the sidewall of the tire on one side are horizontal, and the steering wheel is in the middle position (according to the number of revolutions from the extreme positions).

We make a gasket 28 mm high from a wooden block.

We tie a magnet to the end of the cord (3 m) and attach it to the rim of the rear wheel.

Laying the gasket, we stretch the cord along the car.

The cord should touch both sides of the sidewall of the front tire.

If necessary, loosen the two clamp bolts and turn the steering rod adjusting tube to set the wheel to the desired position.
