III. Check loosening degree of wheel bearing

1、Check bearing axial clearance

Maximum: 0.05mm

2、Check deflection of axle rim

Maximum: 0.05mm

IV.

Check loosening degree of front suspension

V.

Check loosening degree of steering horizontal linkage

VI.

Check loosening degree of knuckle joint end

VII.

Check if shock absorber can operate properly.

1、Check if there’s oil leakage.

2、Check if there’s abrasion of assembly liner.

3、Check damping force of shock absorber. If it’s disqualification, it’s needed to be replaced.

Section 2 Rear Wheel Alignment

It’s commended for the chassis of this vehicle type to use four-wheel position indicator by propulsive line positioning

methods. Single wheel toe-in of front wheel shall be influenced, if propulsive line positioning adjust rear wheel toe-in .So

if carrying out four-wheel alignment test, adjust rear wheel first, then adjust front wheel. And adjust camber of rear wheel

first, then toe-in angle. After that, adjust caster, camber and toe-in angle of front wheel.

I.

Install position indicator or retainer in wheels.

1、Install it according specific instruction of equipment manufacturer.

2、Test and adjust vehicles according to equipment requirement, see the

following alignment requirements:

Note: Camber of rear wheels isn’t adjustable. If finding abnormal tyre abrasion of rear wheels , check if there’s

abrasion and

deformation in rear suspension.

II.

Adjust rear wheel toe-in

If rear wheel toe-in can’t conform to requirements, adjust it. It’s

allowable to adjust offset bolt 16 of rear suspension swinging arm

assembly and change toe-in size (The detailed adjustment procedures

are as follows).

1、 Loosen Nut 18, pay attention not to making nuts drop from

the groove.

2、Rotate offset bolt 16 to change rear wheel toe-in value till

conforming to requirements.

3、Screw Nut18 on to assigned moment of a force

4、After screwing nuts on, bounce vehicle body to check toe-in size.

1、

Negative Caster

Negative caster is assured in design structure. There’s no need to adjust it.

Influence of Caster

Main function of caster is to make vehicles run in the direction of straight front.

If caster is in the right position, the inner of vehicles shall go down when turning front wheels. Its result is to hoist

the chassis and add load to steering knuckle. If two front wheels have the same caster, vehicles will turn back to the

direction of straight front after turning. To add positive caster angle can increase stability of steering wheel, but it’ll

increase turning force when turning. To reduce positive caster angle can decrease stability of steering wheel, but it’ll

decrease turning force when turning. The angle of caster won’t influence abrasion of tyres. It’s used to stabilize vehicle

running direction and make steering wheel turn back by itself when turning. If vehicle equipments are tradition

mechanical turning, the angle of caster is small, without so much as tending to minus caster angle, and it’s easy to turn.

If vehicles are equipped with power-steering, caster is regulated to bigger positive caster and it can make drivers have

more feelings of driving .To add positive caster angle can increase turning force, but it’ll increase stability when running

in the straight direction.

2、

Camber

After installing independent suspension and steering

knuckle, there’s no need to adjust camber normally. If

finding camber deviate tolerance for other reasons, use

binding bolts of independent suspension and steering

knuckle to calibrate.

(1) Before revising, sight check if there’s damage in

running

system

components.

Replace

components

damaged. Camber of front wheels designed by the

manufacturer isn’t adjustable.

(2)

If finding

camber of front wheels exceeds deviation, loosen binding bolts of front shock absorber and steering

knuckle and calibrate it by moving wheels.

3、Front Wheel Toe-in

Use special four-wheel position indicator to test and adjust toe-in.

(1) According to requirements of position indicator, locate wheels to prepare for alignment. Fasten steering wheel in

the direction of straight front with limiting device of

steering wheel, which can be bought in the

market.( Steering wheel must be in the center position of ±5° and lower flange clamping bolt of steering shaft must be

level.)

(2) Loosen the lock nut (1) of steering horizontal linkage.

(3) Dismantle flexible sheath retaining ring (2) with pinchers.

Caution: If retaining ring is lack of elasticity,

It is needed to replace it.

(4) According to requirements, screw toe-in adjusting rod to

adjust the length to assigned value.

(5) Screw lock nut (1) on and install flexible sheath retaining ring (2) again. Check if screwing nuts on and the

sheath is in the right position.

(6) After adjusting front wheel toe-in, check if steering wheel is level. .If not, loosen lock nut of steering wheel and

adjust steering wheel to level position .And screw lock nut of steering wheel on and adjust steering wheel to

requirements of the moment of a force（27~33Nm）.

4、

Check Front Wheel Steering Angle

After replacing horizontal linkage tie-in or adjusting toe-in, check steering angle. If front wheel steering angle can’t

conform to the standard, check and adjust the length of left and right horizontal linkages.
