Press the protective rubber ring to the universal drum
to prevent damage to painted or non-steel rims.
Refer to Figure 5.1-2. From top to bottom the following
cone clamping systems are shown:
A. Back Cone Mounting with Universal Drum.
The cone centers on the wheel from inside. The
drum must make good contact with the wheel on a
flat surface. Never center the wheel with the drum
alone.
B. Back Cone Mounting without Universal Drum.
Only if the drum cannot make sufficient contact with
the rim (e.g.: with very small wheels). Ensure that
the quick release hub nut does not touch the cone.
Use the spacer ring attached to the quick nut en
leu of the drum.
C. Front Cone Mounting.
The cone centers the wheel from outside.
D. Front Cone Mounting with an optional
extension adapter #4026401 in order to elminate
the wheel or tire from touching the balancer
cabinet.
The extension adapter may be required for some
light truck wheels with excessive offset. Such
wheels require they must be moved away from the
balancer mounting flange, in order to eliminate the
wheel or tire from touching the balancer cabinet.
Install the extension adapter on the mounting flange
with the nuts provided. Then mount the wheel, using
the normal front cone method.
E. Double Cone Mounting
The cones must not touch each other. If the cones
touch, the wheel will not be centered and mounted
securely.
Note:
Double cone mounting can be used for
some speciality wheels. The back cone
centered on the formed part of the wheel,
and the front cone centers on the hole.
