4.0 OPERATION OF THE BALANCER
WARNING: Foroperator safety please read
and follow the precautions outlined on
pages 1 and 2 of this manual.
NOTE: Read all instructions before pro-
ceeding with operation of the balancer.
All balancer functions are input into the main computer
through the large easy to read touch panel. Although
each wheel tire assembly differ in some ways all bal-
ancingjobs require basicallythesame procedure. The
order of events to take place are:
1. Inspection of the wheel/tire assembly
2. Mountingwheel onto shaftoradapter
3. Selection of Balancing Mode and Preferences
4. Entry of wheel parameters
5. Spinning the wheel
6. Applying the recommended weight
7. Check spin if desired
8. Dismounting the wheel
The following operation instructions will follow the ba-
sic outline above.
4.1 CHECK LIST - INSPECTION
Observe Before Balancing Wheel
1.Checkforproperairpressure. Ifnotcorrect,inflateto
correct pressure.
2. Check for any foreign material inside tire. If present,
remove before balancing tire.
WATER IS FOREIGN MATERIAL!
3.Removeold weights—old weightsmaybe improper
value or in wrong location.
4.Besure tire andwheel are freeof excessive dirt, rust
andlargestones.Usewire brushonbacksideof wheel
if necessary.
4.2 WHEEL MOUNTING
Nearlyallstandardwheelsandmanyalloywheelshave
accurately machined center holes, and they should be
mounted with center cones. Accurate balancing de-
pends on accurate mounting of the wheel and correct
seatingoftheconeinthepilothole.Insurethatthewheel
is centered on the shaft exactly as it will be mounted to
the vehicle.
Beforestarting anybalancingprocedureitis veryimpor-
tant that the wheel is mounted on the machine with the
properadaptors.Anincorrectcentering ofthe wheelwill
result inconsiderable imbalance.
There are many types of wheels and John Bean sup-
pliesadaptors ofgoodqualityanddurability forthe large
majority.Howeverif youmeetspecial wheelswhichmay
require a specific adaptor, call your authorized John
Bean distributor.
Rims may be divided into these major groups:
1. Car rims with a true center hole.
2. Car rims without a center hole.
3. Car rims with an untrue center hole.
4. Light truck rims.
4.2.1 Standard Wheels (back cone mount)
Mount the wheel as detailed below in Figure 11:
1. Mountproper coneagainst spring plate.
2. Mount wheel on shaft in the same manner as you
would on the car.
3. Mount pressure cup on shaft and place against
outside of wheel, follow with the Quick-nut.
4. Tighten Quick-nut securely with both hands. To
operate the Quick-nut pull the lock-unlock lever
(Figure 12). Slide the Quick-nut on the threaded
shaft. When in contact with the rim, release the
unlock lever and tighten firmly. To assist in
centering the wheel properly, rotate the wheel on
the shaft while tightening the quick nut.

several revolutions while noting any excessive runout.
4.2.2 CENTERING LIGHT-TRUCK WHEELS
Anoptional offsetspacer mayberequiredforsome light
truck wheels and reverse-offset wheels that must be
moved away from the balancer mounting flange. The
extension adaptor is often used with the 5-1/4 inch di-
ameter light truck cone.
Install the spacer on the mounting flange, then mount
the wheel, using the front cone method (Figure 13)
Figure 13
4.3 MODE SELECTION
The majority of balancing takes place in the default 2-
plane dynamic mode which is displayed as "2 PL"
(location 1). Hammer-on clip weights will be placed on
both inside and outside of the rim edge. If required,
select an optional weight placement mode by pressing
theModebuttonuntiltheappropriateplacementmodeis
displayed.
4.3.1 WEIGHT PLACEMENT MODES
Before spinning the wheel (although it may be done af-
terwards)choosetheappropriate balancingmodeforthe
wheel.To selectthe variousplacementmodes pressthe
Mode button until placement LEDs indicate desired
placementposition.
Thebalancingmodesavailableare:
A. DYNAMIC (twoplanes),suggested forall steel rims.
Inthis case thewheel weights mustbe clipped ontothe
rim edges. This function is selected as a default and
the LEDs corresponding to the wheel weight location
are lit on (Figure 15).
B. STATIC (single plane - Figure 16). Suggested for
narrow rims (3" or less). Use a single corrective weight
placed in the center of rim as illustrated in Figure 16.

Raise the wheel guard and turn the wheel until the dis-
plays of the outer plane imbalance position indicator
are illuminated green. A tone will sound indicating top
dead center. Apply the wheel weight at twelve o’clock
position. Use the foot operated shaft lock to prevent
shaft rotation while placing weights.
C. Correcttheinner plane inthe same manner.
4.7 VERIFICATION OF THE RESULTS
Lower the wheel guard to spin the wheel again and
check that the readout is “0.00” “0.00” If a residual
imbalance is displayed:
A. Check the rim parameters, if entered value is incor-
rect, correct as needed. Imbalance values will be re-
computedafter re-spinningwheel.
B. Check if the balancing mode selected is the most
appropriate. If not, choose the right mode and respin.
C.Thewheelweightcould havebeen placedat awrong
position.Tocheck this,position thewheelat thecorrec-
tionposition fortheouter plane.If thewheel weight pre-
viouslyattached isin sector ‘L’or ‘R’(Figure 25), move
thewheelweight up about 1” (2.54cm).
If the wheel weight is in sector ‘D’ cut a piece of the
wheel weight of an approximate value corresponding
to the value shown on the right display, or replace the
wheel weight with a lighter one.
Ifthewheel weight is insector‘U’ add aweightof value
indicated by the display or replace the wheel weight
with a heavier one. Repeat the same operation for the
inner plane.
NOTE: If this situation is repeated, your machine may
beout ofcalibrationand acalibration operationmightbe
requiredas instructed onpage 21.
D.Ifan ALUfunctionwas selectedensurethat thewheel
weightshavebeenplacedin accordancetothe program
chosen.
E. Checkthat the quicknutis tightandthat thewheelis
not slipping against the backing collar.
F. Check that the wheel and adaptors are clean.

4.8 VIBRATION PROBLEMS
If vibration is still present after balancing, check the fol-
lowingpossible sourcesof vibration:
1. Stones caught in the tire tread.
2. Tire slippage on the wheel.
3. Incorrectly mounted wheel.
4. Imbalanced wheel covers.
5. Excessive radial or lateral runout in the tire or
wheel.
6. Damaged wheel bolt holes.
7. Worn universal joints.
8. Imbalanced brake rotors or drums.
9.Worn or damagedbalancer accessories
4.9 Weight Call-Back
Pressing this key allows the operator to recall the origi-
nal weight imbalance value and position to check for
proper weight placement in the event the check spin
callsformore weight whenin the clip-clipmode. When
the previous balance weights and positions are Called
Back, the LED indicator will light and the letters “tdc”
displayed in center digit window that means “top dead
center check”.
1. Press the Weight Call-Back button to activate the
“weightcall back” function.
3. Rotate the wheel assembly by hand until the green
“TDC” LED is illuminated. This is the placement loca-
tion of the original weight amount called out with the
originalweightamountshownintheappropriatewindows.
Makeamount or positioncorrection if needed.
4. Press the [STOP] button to exit the Call Back Func-
tion and the LED indicator will turn off and the “tdc” will
disappear.

5.0 TIRE MATCHING PROGRAM - F90
Tire matching assists the user in determining the best
possible mating of the tire and rim. The mating of tire
andwheelnormally allowstheleast amountofadditional
weightrequired forbalancing andtotal runout.
Thematching programis helpfulwhen:
•Excessive radial runout is noticed.
•The balancer calls for weights in excess of 2 oz. on
eitherplane in theDynamicmode.
TheVPI System III computer wheelbalancerfeaturesa
matchingprogram capableof twolevelsof resolution:
Dynamic,to rotateand reversethe tireon therim for
optimum rim and tire matching.
Static,when thetire has anornate sidewallor direc-
tionaltread and cannotbe reversed onthe rim.
INSTRUCTIONS:
1. Press the "F" button followed by rotating the shaft
until the display. reads "F" “90”, release the "F" button.
When activated the machine displays "--- ACH---" for
onesecond followed by"PUT VAL tOP".Thisinstructs
the operator to rotate the wheel so the inflation valve is
at 12 o'clock. See Figure 26. Press "F" to store the
valveposition, the displaywill then read"ACH SPN 1 ".
NOTE: THE F BUTTON CAN BE PRESSED MORE
THAN ONCE, EVERY TIME THE F BUTTON IS
PRESSED,THEVALVEPOSITION ISREMEMBERED
BYMACHINEASAREFERENCE POINT.
2. Lower the wheel guard to spin the wheel, when the
shaftreaches thebalancing speed,thedisplay reads "-
-- ACH --- "accompaniedwith a short beep.
3. After spinning the shaft brake engages and the dis-
playreads "tur tir---" and"CrS tOP---"alternatively.

TEN AS NECESSARY, WITH EVERY PRESS THE
MACHINE UPDATES THE MEMORY OF THE VALVE
POSITION.
5. The machine displays "ACH SPN 2 ". Lower the
wheel guard to spin the wheel, when the shaft reaches
thebalancingspeed,machinedisplays"---ACH---"along
witha beep.
6. Once the spin cycle is complete, the display reads
"CAL CUL ACH" for one second. Machine calculates
the results based on the previous two spins.
After calculation the machine displays the unbalance
contributions of rim and tire in percentages of total un-
balance to allow operator to evaluate the quality of the
tire or rim. For example, if the total unbalance is 4.5 oz
in which the rim unbalance measured is 3 oz and tire
unbalance is 1.5 oz. In this case, the rim unbalance is
67% of total unbalance and tire is 33%. Machine dis-
plays “ r “ “ 67”and “ t “ “ 33” alternativelyuntil the
operator presses the “F” button. This function allows
operator to check the unbalance contribution of the rim
and tire. If someone has too large unbalance, operator
can stop the procedure and change the bad rim or tire.
From this point, there are three possible procedures to
concludethematchbalanceroutine.These 3procedures
are quite different depending on the results of calcula-
tion.
Procedure 1
Theimbalance measuredin spin2 hasbeen reducedto
anacceptable amount, lessthan2 oz, anditwill notbe
necessarytocontinue matchbalance.Thedisplayreads
"ACH FIN ISH" for one second, and then proceeds to
thenormaltwo-plane balancing mode anddisplaysthe

Procedure 2
Due to a large amount of remaining imbalance the op-
erator can continue match mount. Machine displays
"CRS CRS R" and "TUR TIR ---" alternatively. This in-

Procedure 3
1. Machine displays "CRS CRS L" and "FLP tir ---"
alternatively. Whenthe leftcenter position LEDturns to
green this instructs the operator to turn the wheel and
mark a XX on the left side of the tire at 12 o'clock posi-
tion.
2. If the tire cannot be flipped, press the Cancel/Stop
Buttontoforce machine to procedure2.
Calculationsmay notallow continuationofthematching
process. Ifthis is thecase, machinedisplays"NO NO

respond the machine returns to above state after one
andhalf second.
Ifthe Cancel/Stop Buttonis pressed withinone andhalf
second, machine will display "Qit Qit Qit" for one and
half seconds indicating cancelation of optimization re-
turningthe machine tonormal balancing modes.
If optimization is to be continued with flipping tire, pro-
ceedas described below.

6.0 OPTIMIZATION ROUTINE- F91
The Optimization Routine is very similar to that of the
Match Mount Program (F90). The main difference is
thatoperationbeginswitha bareriminsteadofa rim-tire
assembly. Follow instructions as detailed for in chapter
5.0for F90.
