COATS 1055 Balancer - Manual (Page 14)

Mounting Wheels
Select the most appropriate mounting method for the wheel
you are balancing. Using the proper method ensures secure
mounting and safe balancer operation, and prevents damage to
the wheel.
On most wheels, the inner side of the wheel hub usually has
the most uniform surface for wheel balancing. Always center
the wheel by the most uniformly shaped side of the hub to
achieve the most accurate balance.
Regardless of mounting type, always make sure that the
wheel is forced firmly against the arbor faceplate and that the
hub nut engages the threaded arbor for at least four complete
turns. To assist in centering the wheel properly, rotate the wheel
on the arbor while tightening the hub nut.
Back Cone Mounting
Most original equipment and steel wheels can be mounted
properly using this method. The wheel is centered on a cone
from the inner side of the hub.
1. Place the cone spring on the arbor with the large end
towards the balancer.
2. Select the cone that best fits the center hole in the wheel.
Slide the cone onto the arbor with the large end towards the
spring.
3. Lift the wheel onto the arbor and center it on the cone.
4. Attach the pressure cup to the hub nut and spin the assem-
bly onto the arbor. Tighten securely.
Front Cone Mounting
A wheel should be centered by the outer side of the hub only
when the inner surface will not provide an accurate surface to
center on.
1. Select the cone that best fits the center hole in the wheel.
2. Lift the wheel onto the arbor and slide it back against the
arbor faceplate.
3. Slide the cone onto the arbor and into the center of the
wheel. Then lift the tire to seat the cone in the center hole.
4. Spin the hub nut (without the pressure cup) onto the arbor.
Tighten it securely against the cone.
