4.2.3 WHEEL MOUNTING REQUIRING
SPECIAL TOOLING
Clad wheels: A Clad Wheel is a wheel casting that is
balanced but the wheel face is not fi nished. To fi nish
the wheel face a plastic chromed face is bonded to
the casting.
A clad wheel must be centered properly from the back
side of the wheel using precision collets instead of a
centering cone. A precision collet is normally a dual
sided centering device with low tapers on each side
and has a length of approximately 1.5 inches.
The benefi t of a precision collet is it fi ts very precisely
into the tapered machining on the back side of a cast
wheel and the collet does not protrude into the wheel
center. A cone also offers precision centering, but a
cone can have a length from the long to short end of
the taper of two inches or more. A taper cone unlike a
precision collet, will intrude into the wheel center.
On many clad wheels there are plastic tabs to hold the
cosmetic cover in place. It is also necessary to use a
pin plate in the front of the wheel.
The standard pressure cup may crack the plastic clad-
ding.
A centering cone can break off the tabs. See section
1.6 Optional Accessories for tooling recommendations.
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
the Mode button until the appropriate placement mode
is displayed.

4.3.1 WEIGHT PLACEMENT MODES
Before Spinning the wheel (although it may be done
afterwards) choose the appropriate balancing mode
for the wheel. To select the various placement modes
press the (9) Weight Placement button;
until placement LEDs indicate desired placement
position.
A. DYNAMIC (two planes), suggested for all steel rims.
In this case the wheel weights must be clipped onto the
rim edges. This function is selected as a default and
the LEDs corresponding to the wheel weight location
are lit on (Figure 19)
Figure 19
B. STATIC (single plane - Figure 20). Suggested for
narrow rims (3" or less). Use a single corrective weight
placed in the center of rim as illustrated in Figure 20.
Figure 20
To select the STATIC Mode:
1. Touch the SAPE arm to the rim fl ange.
2. Enter the rim width dimension.
3. Press four times Alu button (9).
WEIGHT COMBINATION MODES USING THE
WEIGHT SELECTION BUTTON
See (Figure 21). Pressing the weight selection button
(9) will toggle the LED's to the weight default selections
as shown. Balancing using a combination of hammer-on
and adhesive weights as shown in Figure 21.
