Determining Balancing
Mode
Dynamic Balancing
This is the default mode for the balancer.
This mode places weights on both the inner and outer plane of
the wheel.
Static Balancing
This mode determines the position for a single adhesive
weight along the centerline of the wheel. Wheels balanced in
this mode may wobble if the imbalance mass is large enough
and off the centerline of the wheel width. Wobble caused by an
off center imbalance can only be corrected by dynamic balanc-
ing of the wheel.
When this mode is selected, the computer automatically cal-
culates the middle of the wheel and the proper weight position.
When attaching the weight, it is important that it be positioned
as accurately as possible at the centerline (figure 14).
Attach the adhesive weight according to the top-dead-center
positioning LEDs as described in the Balancing a Wheel section
on page 8.
Important: After balancing the wheel, it is necessary to verify
that the weight will clear the brake caliper when the wheel is
mounted on the vehicle. The weight must not contact the brake
caliper, or any other brake components when the wheel is
mounted.
Note: It is advisable to cover the adhesive weight with a strip
of duct tape to help prevent deterioration of the weight adhe-
sive. Adhesive backed aluminum foil may also be used. Smooth
out the covering to eliminate air pockets and bubbles, and
smooth down all edges and corners.
Alloy Balancing
Balance specialty wheels with adhesive weights in this mode.
The computer automatically calculates the outer weight position
as the centerline of the wheel, and the inner weight position
under the rim flange (figure 15).
Position the weights at top-dead-center as described in the
Balancing A Wheel section. Make sure the outer weight is
placed as accurately as possible to the centerline on a horizon-
tal surface. Cover the weights with duct tape or adhesive
backed aluminum foil as describe in Static Balancing (figure 16).
