Chrysler laser 1990, talon 1990 Technical Information Manual
SAFETY
NOTICE
CAUTION
ALL SERVICE AND REBUILDING INSTRUCTIONS CONTAINED HEREIN ARE
APPLICABLE TO, AND FOR THE CONVENIENCE OF, THE AUTOMOTIVE
TRADE ONLY. All test and repair procedures on components or assemblies in
non-automotive applications should be repaired in accordance with instructions
supplied by the manufacturer of the total product.
Proper service and repair is
important to the safe, reliable, operation of
all
motor
vehicles.
The service procedures recommended and described in
this publication
were developed
for professional
servlTe
personnel
and are
effective
methods
for performing vehicle
repair.
Following these procedures will help assure efficient
economical vehicle
performance
and service
reliability. Some of these
service procedures
require the
use
of
special tools designed
for specific
procedures.
These
special tools should
be
used when
recommended throughout this
publication.
Special attention should be exercised when working with spring or tension loaded
fasteners and devices such as E-Clips, Circlips, Snap rings, etc., as careless removal
may cause personal injury. Always wear safety goggles whenever working on
vehicles or vehicle components.
7
It is
important to
note
that
this
publication contains
various
Cautions
and
Warnings.
These
should be
carefully
read in order to
minimize the
risk of personal
injury, or
the
possibility
that, improper service
methods may
damage
the vehicle or
render
it
unsafe.
It is important to note that these Cautions
and
Warnings cover only the situations
and
procedures
Chrysler Motors
has
encountered
and recommended.
Chrysler Motors
could
not possibly know,
evaluate, and advise
the service
trade of all
conceivable
ways that
service
may *be performed, or of
the possible
hazards of each.
Consequently, Chrysler
Motors
has
not
undertaken any such broad
service
review.
Accordingly, anyone
who
uses a service procedure, or
tool, that is not
recommended in
this publication,
must assure
oneself
thoroughly that neither
personal
safety,
nor
vehicle safety, be jeopardized by
the service
methods
they select.

FEATURES
High performance and low fuel consumption
l The rocker arm reduces the valve-actuation torque as well as fuel consumption.
l Air-intake efficiency improved through the adoption of the optimum air-intake system layout.
l Improved response and fuel consumption has been achieved by electronic control multipoint
fuel injection.
l Water-cooled turbocharger. <Turbo>
Quiet operation
l Noise and vibration have been decreased by the adoption of roller rocker arms.
l Noise generated by the valve mechanism has been decreased by the hydraulic auto lash adjusters.
l Vibrations have been decreased by the adoption of bearing caps with beams which increase the
rigidity of the crankshaft support points.
-
Serviceability
l Complete self-diagnosis functions.
l Enhanced reliability through the adoption of gold-plated connector terminals.
l Use of an auto tensioner achieves maintenance-free, automatic adjustment of timing belt
tension.
l Use of the auto lash adjusters achieves maintenance-free, automatic adjustment of valve clearance

THEFT-ALARM SYSTEM (OPTION for
4WD
VEHICLES)
To make the vehicle theftproof, this system is so
designed that the headlights go on and off and the
horn is sounded intermittently for ‘about three
minutes when the locked door, hood or liftgate has
been forced open without using a key.
Furthermore, the starter circuit is interrupted so that
the engine may not be operated, making the vehicle
theftproof.
About 20 seconds after all doors are closed
and locked, the rear hatch is closed, and the
hood is closed---t SYSTEM ARMED

Anti-dive Geometry / Negative-offset Geometry
2-5
ANTI-DIVE GEOMETRY
RO2cAAA
Ordinarily, when the brakes are applied, the load is moved
toward the front of the vehicle as the result of inertial force, and
this causes the phenomenon known as “nose dive”, in which
the front of the vehicle is caused to tilt forward and downward.
For this front suspension, however, the suspension link design
-which has a high
“anti-dive”
effect- is such that the lower
arm is tilted forward in order to counteract the “nose dive”
phenomenon.
In other words, braking force F is divided into force components F, and
F2;
of these, F1 acts in the direction that expands
the front spring, with an effect that reduces the “nose dive”
phenomenon.
NEGATIVE-OFFSET GEOMETRY
AOZDAAA
For negative-offset geometry. the king pin offset
angle is outside the center point of tire-to-ground
contact. Thus, for example, if a tire on the right side
is punctured during driving, or if the brakes are
applied while the left tires are on a slippery surface
(ice, etc.), the vehicle would be inclined to swerve to
the side (in this case the right side) of greater road
surface resistance to the tires, but, because of the
negative-offset geometry construction, a certain
force would be generated to cause rotation in
direction C, employing point A as the fulcrum point.
At the same time, there would be generated at the
tires on the opposite side a corresponding force to
cause rotation in direction D, also employing point A
as the fulcrum point, but, because that force is
Centre ooint
of
strut
Pati
greater in direction C (where road surface resistance
is greater), the tires themselves will tend to turn in
the left direction. As a result,. because
t.he
tires
automatically countersteer in the left direction, even
though the force applied to the vehicle by the road
surface resistance is to the right, the system thus
functions to maintain the vehicle on a relatively
straight-ahead course.
NOTE
The king pin offset is the distance from the center
point of tire-to-ground contact when a line (extended to the road surface) is drawn to connect the
ball joint center point and the center point of the
strut upper installation part.

Offset Spring
OFFSET SPRING
Because struts are installed at an angle, the road
surface reaction force
(RI)
applied to the tyres tends
to act vertically upon the tyre centre, and that force
tries to bend the strut toward the inside of the
vehicle. When this happens, the force trying to bend
the strut toward the inside of the vetiicle acts upon
the strut bearing component as bending moment
reaction force FL (because the upper part of the strut
is fixed in place), thus increasing the friction of the
bearing, and, as a result of the bending of the strut,
amplifying the moving resistance of the shock
absorber.
Ro2EMA
Then, because the coil spring is installed so that
its
centre is greatly offset (toward the outside of the
vehicle) from the centre of the strut, the counteractive force for the spring tends to become great
toward the outside of the vehicle, thus resulting in
the generation of bending force FL opposite to the
bending of the strut, and thereby decreasing the
friction applied to the strut bearing. As a result, the
shock absorber’s internal movement friction is
reduced, thereby improving riding comfort as well
as the durability of components.

LOWER ARM
ROZGAAA
The lower arm is an A-type arm, and is connected,
via a rubber bushing, to the crossmember.
The rod bushing is optimum tuned, including the
spring constant of the arm bushing, to provide
and “hard” characteristics relative to the left and
right, so that road surface impacts during travel are
alleviated, and also so that changes of alignment
caused by lateral forces are reduced, thus assuring
“soft” characteristics relative to the front and rear
excellent I driving stability.

The stabilizer mounting uses

adoption of a stabilizer link with a pillow ball on each
end increases the link stiffness and ensures the
effective operation of the stabilizer bar even when a
small rolling motion occurs,
