26 3. Mounting Wheels on the Balancer GSP9700 Series Road Force Measurement System Operation
Using Plastic Wheel Mounting Washer
The plastic wheel mounting washer, 46-320-2, is used to prevent scratches on
wheels where the standard plastic cup and scratch guard cannot be used. The plastic
wheel mounting washer can also be used when mounting a wheel with a large offset
that is between cone sizes. Use of the washer as shown below can improve
centering ability by increasing cone pressure against the wheel.
For example: One cone size is too small because the captivated spring is not
pressing the cone against the inner wheel opening, but the next larger cone size is
too big and will not fit the opening. Use the smaller cone size with the plastic wheel
mounting washer to “extend” the captivated spring to hold the mounting cone against
the wheel opening with greater pressure.

The scratch guard may be installed on the clamping cup to protect aluminum rims
from being marred, but should not be used on steel wheels.
NOTE: Use only the wing nut supplied with the GSP9700.
In some cases, the mounting pad of the wheel may be extremely wide, and the
standard clamp cup will not properly contact the wheel hub area. In these cases, the
optional nine-inch alloy wheel pressure cup may be used in place of the clamping cup.
