manufactured by Launch Tech Co., Ltd.

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.

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

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.

z The driver has to firmly hold the steering wheel

to maintain a straight-ahead driving.

z Abnormal wear of tires occurs, such as single

side wear, concave-convexity wear and
featheriness wear.

z Too heavy or too light steering, or shaking at

high-speed driving.

z When the tire(s), steering knuckle or shock

absorber are replaced.

z When the vehicle is impacted.
z When 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.

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).

1-1

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

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.
z Rear wheel driven: the thrust angle equals half of

the toe-in difference between the two rear wheels.
As shown in Fig.1.5.

z Front wheel driven: the thrust angle equals half

of the toe-in difference between the two front
wheels.

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.

z Four-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.

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

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

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.

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

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

4-4

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

j

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.

The computer (main unit) is of the master control
equipment of the former wheel aligner, and the
calculation and display, etc. are all performed on the
main unit.
Working mode with computer: In this mode, you can
perform the wheel alignment operation with the

Some Explanations about No PC Mode of X-631+
Wheel Aligner

1. The probe rod via which the system enters No
PC Mode is of the main probe rod. The main
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.

4-24

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

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
X-631 wheel aligner. When the computer is
put into work, the probe rod will automatically
exit No PC Mode.
