9.3.2. Disorder / a convergence of wheels

THE GENERAL DATA

Adjustment of installation of wheels

It is recommended to inspect adjustment of wheels after at least 1000–1200 km of run when suspension bracket springs had time to enter into a normal operating mode.

For check it is necessary:

      – Exact adjustment of the measuring equipment;
      – That the weight of the car at check carrying out equaled only to its own weight with the filled tank and the established equipment;
      – That pressure in tyres equaled to the standard;
      – That the car has been located on an equal surface, also before carrying out of check the car is necessary for rocking some times to establish a suspension bracket;
      – That there was no excessive free wheeling in the steering mechanism;
      – Check up a suspension bracket on presence of an excessive free wheeling and damages.

Definition / adjustment of a corner of a convergence of back wheels (for cars with a forward drive)

1. If a corner of a convergence of both wheels positive (+ / +) or negative (-/-), subtract smaller value from большего and divide on 2.

2. If a corner of a convergence of one wheel positive, and the second negative (+/-), combine both values and divide on 2.

Disorder of forward wheels, adjustment (for cars with the spherical hinges of a forward suspension bracket fastening in 2 points)

PERFORMANCE ORDER

1) ослабьте both nuts of fastening of the spherical hinge to the suspension bracket lever (are specified by arrows) 2) move the spherical hinge by means of the lever and adjust a corner of disorder of forward wheels 3) tighten nuts of fastening to 65 Н.м. 4) repeatedly check up a corner of disorder of wheels and adjust it if it is necessary 5) check up a corner of a convergence of wheels, adjust it if it is necessary
