15.2. Check and adjustment of angles of installation of wheels

Preliminary check

PERFORMANCE ORDER
1. Check pressure in tires and, if necessary, finish to demanded.
2. Check a side play of bearings of forward wheels and, if necessary, replace them.
3. Check a beating of tires and wheels.
4. Check lack of a side play of spherical hinges of a forward suspension bracket and steering transfer.
5. The car has to be on a flat horizontal surface without passengers and freight in a luggage carrier.
6. Shake a car body to check operation of shock-absorbers.
7. Distinction in height, between the left and right side of the car from the center of a wheel to edge of a wing should not exceed 10 mm.
8. Check that the fuel tank full, levels of cooling liquid and engine oil is normal also the spare wheel and tools are on the places.

Check of the maximum angle of rotation of forward wheels

PERFORMANCE ORDER
1. Establish both forward wheels in a turn radius template.
2. Turn forward wheels to the left against the stop and measure an angle of rotation left (internal) and right (external) wheels.
3. Weaken the left and right lock-nuts of tips of steering drafts, then, rotating drafts, establish the required corners. Tighten lock-nuts.
4. Repeat these operations after turn of forward wheels to the right against the stop.
5. Tighten lock-nuts of tips of steering drafts.

Inhaling moment: 34–50 N • m
6. Check and, if necessary, adjust a convergence, after check and adjustment of the maximum angle of rotation of forward wheels.

Disorder and corner of a longitudinal inclination шкворня forward wheels

PERFORMANCE ORDER
1. At the special stand check disorder and a corner of a longitudinal inclination шкворня.
2. If value of corners differs from demanded, lift a forward part of the car and fix on support.
3. Turn out four nuts of the top fastening of a rack of a forward suspension bracket.

4. Press the top fastening of a rack of a forward suspension bracket for release of plugs down and turn plugs in situation which corresponds to a difference of corners between the measured and demanded values.
5. Tighten nuts of the top fastening of a rack of a forward suspension bracket the required moment.

Inhaling moment: 23–29 N • m
6. Lower the car and check corners of disorder and a longitudinal inclination шкворня. If necessary, modify corners.

Convergence of forward wheels

PERFORMANCE ORDER
1. At the special stand check a convergence of forward wheels.
2. If the convergence does not correspond to the required value, weaken the left and right lock-nuts of tips of steering drafts, then, rotating drafts, establish the required corners. Tighten lock-nuts.

Prevention

The left and right tips of steering drafts have the right carving. For reduction a convergence it is necessary to rotate the right and left steering drafts, turning out them from tips of steering drafts and vice versa.

One full turn of both connecting drafts changes a positive convergence approximately to 6 mm.

Maybe it is necessary to rotate one steering draft more than another to reach the required convergence corner, at preservation of installation of provision of a steering wheel.


3. Tighten lock-nuts of tips of steering drafts.

Inhaling moment: 34–50 N • m
 

Adjustment of a convergence of back wheels


Prevention

Disorder of back wheels is not regulated.


PERFORMANCE ORDER
1. Check that the fuel tank full, levels of cooling liquid and engine oil is normal also the spare wheel and tools are on the places. The car has to be on a flat horizontal surface.
2. At the special stand check a convergence of back wheels.
3. If the convergence does not correspond to the required value, weaken lock-nuts on back cross draft.
4. Turning the regulator on draft, adjust a convergence of the corresponding back wheel.

Prevention

One turn of the regulator changes a convergence to 3 mm.


5. Repeat adjustment for the second back wheel.
6. Tighten lock-nuts the required moment.

Inhaling moment: 116–157 N • m
