WHEEL MOUNTING METHODS
(AUTOMOBILE WHEELS)
Back Cone Mounting
Back cone mounting is the most common way to mount
automobile wheels. Choose the cone that fits best
when placed through the wheel center hole from the
rear. Slide the cone spring and cone on the shaf t. Place
the wheel on the cone and be sure that the cone center
the wheel when you tighten the handle.
The pressure drum should contact the wheel on a flat
surface. Do not center the wheel with the pressure drum.
Tighten the wheel firmly against the mounting flange.
Hold the handle in place and rotate the wheel when
tightening. Be sure that the wheel is firmly against the
mounting flange and the handle threads engage at least
three turns on the shaft.
Front Cone Mounting
Front cone mounting is required when using light truck
wheels and is also an acceptable alternative for many
automobile wheels. The wheel center hole must be
true on the outside of the wheel to use the front cone
mounting method.
Choose the cone that fits best when placed through
the wheel center hole from the front. Slide the wheel on
the balancer shaft without a back cone or spring on the
shaft. Place a cone on the shaft, through the front of
the wheel. Be sure the cone center the wheel and that
the wheel is squarely against the mounting flange when
you tighten the handle.
