Steelman ChassisEar Manual De Instrucciones página 6

USE FOR :
 Road Test Diagnosis
 Under Chassis
 Under Hood
 Fuel Injectors
The ChassisEAR is a versatile electronic listening tool which is designed to allow the
user to listen to amplified sounds through a professional set of headphones during a
road test. (See #5 under "How to use").
There are 6 extremely sensitive microphone / clamps that can be attached adjacent
to many difficult to diagnose vehicle parts.
Some of these vehicle parts/areas include:
1. wheel bearings
2. brake calipers
3. c.v. joints
4. leaf and coil springs
5. differential
6. transmission
7. body squeaks and rattles
8. under dash
During a road test, these parts do not make the same sound when the car is on a
hoist. In order to accurately diagnose an undercar problem the car must be driven
during diagnosis so that all parts and bearings are under full load and actual driving
conditions.
Before using ChassisEAR for the first time, it is a good idea to identify the
components of ChassisEAR.
REPLACEMENT PARTS
STE06610 – control box with color coded selection switch
STE06635 – set of 6 microphone clamps with 16 foot lead
STE65010 – 1 headphone
STE00413 – Metal probe
STE00411- Noise amplifier
A 9-volt battery is included.
Keep ChassisEAR in the ABS case when not in use and keep the microphone /
clamps and ties in the vinyl pouch that is provided. This will minimize damage and
loss of components when not in use.
HOW TO USE
1. With vehicle elevated attach the clamps to the suspect areas. If, for example, you
suspect there is a bad wheel bearing, attach the clamps, one each, per wheel
bearing. Put the clamp on the tie rod or knuckle close to the inside of the wheel.
In order to generate an exact cross-comparison, place the clamp on identical
locations. Attach the other two clamps to the transmission and differential since
many times what you think is a wheel bearing, turns out to be something else. Or
if you suspect a brake problem, attach the first 4 clamps adjacent to the brakes.
The closer the clamp is positioned to the suspect problem, the better sound
reproduction you will get.
