A matching procedure may involve the loos-
ening of tire beads and the inflation of a tire.
Training is necessary in tire changer opera-
tion and understanding the dangers
involved during bead seating and tire infla-
tion before attempting this stage of a
matching procedure. Read the operators
manual supplied with the tire changer and
consult a supervisor.
The operator can choose from two procedures to cor-
rect for a runout condition. Typically, if the static limit
unbalance is exceeded, the operator will choose
Optimization (Match Balance) to correct the situation.
Or, if the radial runout limit is exceeded, the operator
will choose to use the Runout (Runout Match) proce-
dure to correct the situation.
Whenever a large unbalance or runout condition is
detected, a runout procedure can be accessed manu-
ally by selecting the
button and then either the
OPTIMIZATION (MATCH BALANCE) option
or the
the RUNOUT (RUNOUT MATCH) option
.
To view the Static-on-Screen™ value, press the
key, select the SPECIAL FUNCTIONS option
, and
set the STATIC UNBALANCE DISPLAYED option
to ON. The Static-on-Screen™ reading, see page 11,
will appear in the upper left-hand side of the screen.
Automatic Runout Detection
The wheel balancer software can be set to automati-
cally detect a wheel assembly that exceeds the static
limit unbalance or radial runout limit. A Runout
Diagnostic screen will appear, see figure 36, that pro-
vides on-screen information for the operator.
Figure 36 - Runout Diagnostic Screen
To set the wheel balancer to automatically detect
runout, press the
button, select the BALANC-
ING SET-UP option
, and set the RUNOUT DIAG-
NOSTIC option
to ON.
When the Runout Diagnostic option is ON, the radial
runout sensor should also be set. Press the
but-
ton, select the GENERAL SET-UP option
, and set
the RUNOUT UNLOADED
option to
SONAR.
The Runout Diagnostic screen will always appear
when the measured runout exceeds the MAX. TRUE
RUNOUT LIMIT setting. To change this setting, press
the
button, select the BALANCING SET-UP
option
, and select the RUNOUT LIMITS option
. Then select the MAX. TRUE RUNOUT LIMIT
option
; press and hold the button down to scroll
to the desired amount.
Note:
If the Runout Diagnostic screen appears and
the runout is below the set limit, it is because the static
unbalance exceeds 3.00 ounces. In this case, consider
the OPTIMIZATION (MATCH BALANCE) procedure to
correct the condition.
Also at the runout limits screen (RUNOUT LIMITS
option
), select the RIM RUNOUT LIMIT option
to scroll to the desired rim tolerance amount and
select the CORRECTION RUNOUT LIMIT option
to scroll to the desired tire/wheel tolerance amount.
