BALANCING PROCEDURES 21
3.2 Mounting the Wheel on the
Balancer Spindle Shaft
Use only cones, collets and accessories that
are specifically designed for the SmartWeight
Touch®/GSP9200 Touch GSP9700.
Since today’s vehicle designs are lighter and more
sensitive to road feel, it is critical to achieve the best
balance. Proper balance requires that the tire/wheel
assembly be centered on the balancer. Tire/wheel
assemblies can be balanced to zero, even with the tire/
wheel assembly mounted off-center. The main objective
of the balancer operator is to center the wheel on the
hub and shaft, using the best available method. Mounting
the wheel off-center creates incorrect measurements of
imbalance and runout conditions.
Remove any existing wheel weights, rocks, and debris
from the tire tread, and clean the center hole of the
wheel. Inspect inside of wheel for excessive accumulation
of dirt and debris. Remove if necessary before balancing.
Accurate balancing depends on accurately centering the
wheel. Choose the proper Bullseye™ Centering System
collet by placing it in the center hole of the wheel to be
balanced.
If basic collets and adaptors do not fit the
wheel, additional centering adaptors will be
necessary. A wheel that cannot be properly
centered, cannot be properly balanced. All
balancers require additional centering adaptors
to properly center certain types of wheels. For
additional information, refer to “Wheel Balancer
Accessories”, Form 3203-T for optional
accessories.
