Introduction

Thank you for using X-631/X-631+ wheel aligner

manufactured by Launch Tech Co., Ltd.

Definition

X-631/X-631+ CCD wheel aligner adopts the charge

coupled device (CCD) with high resolution, the

clinometer with high precision and the accurate optics

imaging system.

X-631/X-631+ is a device designed to measure the

wheel alignment parameters and compare them with

the specifications provided by vehicle manufacturer. It

also gives instructions to the user for performing

corresponding adjustments so as to get the best

steering performance and reduce tire wear.

The wheel aligner compares the measured results

with the original data of vehicle manufacturer and

gives instruction to the user for adjustment, so its

databank should contain enough information.

X-631/X-631+ Wheel Aligner contains wheel

alignment databank of over 10,000 vehicle types all

over the world. User can also add new vehicle wheel

alignment data in the databank when necessary.

When Is Wheel Alignment

Required

zThe driver has to firmly hold the steering wheel

to maintain a straight-ahead driving.

zAbnormal wear of tires occurs, such as single

side wear, concave-convexity wear and

featheriness wear.

zToo heavy or too light steering, or shaking at

high-speed driving.

zWhen the tire(s), steering knuckle or shock

absorber are replaced.

zWhen the vehicle is impacted.

zWhen the vehicle has covered the first 3000km

or 10000km.

Main Vehicle Alignment

Parameter

The wheel alignment mainly consists of camber,

toe-in, kingpin inclination, caster, etc. They are

designed mainly to improve the steering performance

and driving stability of the vehicle, and reduce tire

wear.

Camber

Camber is the leaning of the wheel inwards or

outwards from the vertical.

If the road wheel leans outwards from the vertical, it

has positive camber and when leaning inwards from

the vertical - negative camber, looking from the front

or rear of the vehicle. See Fig.1.1.

Fig.1.1

Camber is measured in degrees.

Toe-in and Toe-out

The toe setting is the amount by which the front or

rear wheels point inwards or outwards at the front of

the wheel in relation to each other (see Fig.1.2).

When the wheels point inwards they are said to toe-in.

Toe-in figures are given a positive value. Conversely

when the wheels point outwards they are toe-out and

the figures are shown as a negative value.

Fig.1.2

The purpose of correct toe is to ensure that the

wheels run parallel when the vehicle is driving. An

incorrect toe setting may affect the stability and

controllability of the vehicle.

Kingpin Inclination (Steering Axle

Inclination SAI)

Kingpin Inclination (KPI or SAI) is the angle of

inclination of the king pin towards the centre-line of

the vehicle from the vertical (see Fig.1.3).

LAUNCH X-631/ X-631+ Wheel Aligner Introduction

1-2

Fig.1.3

Correct Kingpin Inclination can equalize the loads

applied on bearings so that the life of bearings can be

prolonged and the controllability of steering is

improved.

Without the inclination, the controllability of the

steering may be affected; further more, the vehicle

weight and the ground counterforce may cause

significant stress in the axle and finally damage the

axle.

Correct inclination of king pin is also helpful for the

vehicle to restore its straight-ahead position after

steering.

Kingpin Inclination is determined when the vehicle

suspension is designed. It is not service adjustable.

Caster

Caster is the tilting of the kingpin either forwards or

backwards from vertical, as viewed from side of the

vehicle. See Fig.1.4

Fig.1.4

When the king pin is tilted backwards from the vertical,

caster is positive. When the king pin is tilted forwards,

caster is negative.

Caster angle influences the directional stability of the

steering. To increase the tendency of the steering to

self-centre, the steering will normally be designed

with positive caster.

Thrust angle

The thrust angle is defined according to the driven

mode of vehicle.

zRear wheel driven: the thrust angle equals half of

the toe-in difference between the two rear wheels.

As shown in Fig.1.5.

zFront wheel driven: the thrust angle equals half

of the toe-in difference between the two front

wheels.

zFour-wheel driven: the thrust angle equals half of

the toe-in difference between the two front

wheels plus half of the toe-in difference between

the two rear wheels.

The thrust angle is defined as positive when the

thrust line is towards left and negative when the line

is towards right.

If the thrust angle is not zero, the vehicle will have the

side-moving trend. In this case, adjust the front toe-in

of the drive wheels first, and then adjust the toe-in of

driven wheels.

Fig.1.5

Wheelbase Difference

Wheelbase difference is defined as the angle

between the joint line of the centre of two rear wheels

and that of the front wheels. It is positive when

distance between the centre of the right wheels is

large than that of left wheels; and negative otherwise.

If the tread is available from the vehicle specifications,

then the wheelbase difference can be also expressed

by angle. See Fig. 1.6

LAUNCH X-631/ X-631+ Wheel Aligner Introduction

1-3



Fig. 1.6

Track Width Difference

Track width difference is defined as the angle

between the joint line of the ground-contact point of

left wheels and that of the right wheels. It is positive

when distance between the centre of the rear wheels

is large than that of front wheels; and negative

otherwise. If the wheelbases are available from the

vehicle specifications, then the tread difference can

be also expressed by angle. See Fig. 1.7.

procedure.

Operating procedures:

1. Keep the vehicle wheels on straight-ahead

positions, fix the steering wheel with the steering

wheel holder, remove the brake pedal depressor

to keep the wheels can be freely rotated.

2. Install four wheel clamps and probe rods, and

then adjust each probe rod level respectively.

3. According to the prompts on the screen, start the

run-out compensation operation for LF wheel.

Adjust LF probe rod level, and click [NEXT] after

finished.

wheel by 180°. Adjust LF probe rod level, and

click [NEXT] after finished.

5. According to the prompts on the screen, turn LF

wheel by 360°. Adjust LF probe rod level, and

click [NEXT] after finished.

6. According to the prompts on the screen, perform

the run-out compensation operation for RF, RR

and LR wheel respectively.

7. Put down the vehicle body, keep the four wheels

on the ground. Shake the vehicle body, keep four

wheels cling to the ground, the run-out

compensation operation is finished (The

interface displays the values of run-out

compensation).

Caution:

1. Before performing run-out compensation

operation, be sure to fix the steering wheel

according to the requirements, in order to avoid

the wheels' swing to left or right when performing

run-out compensation operation, causing the

inaccurate run-out compensation.

2. You are required to swing the vehicle tires when

performing the run-out compensation operation.

Keep each probe rod to be at rest comparatively

and level (if some probe rod is not level during

operating, the system cannot perform the next

operation until the probe rod is adjusted level).

3. If the left wheels and right wheels of some

vehicles are linked (i.e. when left wheel rotates,

the right wheel rotates, too), and you want to

perform run-out compensation operation, you

must hold the right (left) wheel when you rotate

the left (right) wheel, and you should notice that

force from you hands must be balanced (in order

to avoid wheel's swing to left and right and

causing inaccurate run-out compensation).

Meanwhile you should check if the probe rods

are level or not. If not, it is necessary to adjust

the probe rods level by the way of rotating the

wheels. You should note that the probe rods

mustn't be adjusted level by the way of loosing

them.

4. If the second-time lift can put up the front and

rear axles at the same time, the front and rear

axles should be put up at the same time when

performing the run-out compensation operations;

if the second-time lift can only put up one axle at

a time, please put up the front axle individually

when performing the front wheel run-out

compensation operations, and put up the rear

axle individually when performing the rear wheel

run-out compensation operations.

5. Three types of run-out compensation operation

modes (90°, 180° and rolling run-out

compensation) can be set on the interface of

[System Management]-[System Setting].

180°run-out compensation mode is a standard

one. It is with high accuracy, and cross reference

between front and rear probe rod is necessary

The icon for the level status

robe rod Previous

LAUNCH X-631/X-631+ Wheel Aligner Operation Instructions

for the measurement under this mode; the

accuracy of 90°run-out compensation mode is

comparatively lower, but each probe rod can

finish run-out compensation operation

independently under this mode, needless to take

other probe rod as reference. This run-out

compensation operation mode can be selected in

the case of CCD sensor cannot work normally

caused by second-time lift or other factors; it is

not required to lift up the vehicle during rolling

run-out compensation operation. Only

vehicle-pushing is required to accomplish the

run-out compensation operation. Among the

three kinds of run-out compensation modes

mentioned above, the accuracy of rolling run-out

compensation is lowest.

Vehicle-pushing Run-out Compensation

Vehicle-pushing run-out compensation is mainly used

for getting the inherent parameters of the four wheels

before the normal measurement, so as to ensure the

measurement more accurate. You do not always

perform this operation. If the measurement is

accurate, the user can directly skip this step, and start

from Caster Swing measurement. The interface is as

shown in Fig.4.11:

Fig.4.11

Operating procedures:

1. Turn the steering wheel to make the front wheels

on straight-ahead position. Hold the steering

wheel with the steering wheel holder, and then

remove the brake pedal depressor;

2. Respectively install four wheel clamps and probe

rods, and then adjust each probe rod level;

3. Release all four probe rods respectively, and

push the vehicle back by 45°, and then adjust all

probe rods level. Please click [NEXT] after

finished;

4. Push the vehicle back to the original position,

and then adjust all probe rods level. Please click

[NEXT] after finished.

Caster Swing

Kingpin measurement is aimed at the front wheels,

which includes kingpin inclination and caster. Correct

Kingpin Inclination can equalize the loads applied on

bearings so that the life of bearings can be prolonged

and the controllability of steering is improved. The

existence of kingpin inclination can make the

intersection point of steering axes and road surface

be in front of the adherent point between tire and the

ground, which can make use of the resistance from

the road surface to the tire to keep the vehicle driven

straight-ahead. The interface is as shown in Fig.4.12.

Fig.4.12

Operating procedures:

1. Adjust the steering wheel to straight-ahead status,

i.e. when the toe-in of FL wheel is equal to the

toe-in of RF wheel, the small round ball on the

operating interface will move to middle position

and turn green from red. At this moment you can

adjust all probe rods level.

2. Turn the steering wheel left or right, after arriving

at the desired position, the small ball turns green

again from red. It indicates that the acquisition for

this side is finished.

3. Center the steering wheel, and turn it in reverse

direction, after arriving at the desired position, the

newly created small ball turns green again from

red, and the acquisition is finished.

probe rod can perform the control functions

(just like main unit) under No PC Mode.

2. One set of probe rods has one main probe rod

only.

3. The label of the main probe rod is included

with square brackets ([ ]). For example, [FL]:

It indicates that FL is of the current main

probe rod.

4. If this set of probe rods has had the main

probe rod, the other probe rod cannot be set

as the main probe rod once more. If you force

to do it, the error prompts will be displayed.

Fig.4.99

Error prompts: Setting failed! [XX] is Main bar.

5. After entering main working interface, the

camber data will usually be displayed. Only

after entering No PC Mode can the toe-in data

be displayed. The toe-in data will become

invalid after the system exits No PC Mode.

Battery electricity Qty.

6. When the data of camber and toe-in is valid,

the corresponding data will be displayed;

when invalid, “-----” will be displayed.

7. When the system uses two-probe rod working

mode, toe-in is of total toe-in, indicated by

“TT”; when the system uses four-probe rod

working mode, toe-in is of individual toe-in,

indicated by “T”.

8. When X-631+ wheel aligner uses No PC

Mode, the displayed data units of camber and

toe-in are all in Degree/Minute mode.

9. X-631+ wheel aligner supports all functions of
