Mounting Wheel On Balancer
Shaft
CAUTION
Avoid back injury, seek assistance when
lifting heavy tire/rim assemblies onto the
balancer shaft.
CAUTION
Failure to tighten the hub nut properly may
result in the wheel dismounting, causing
personal injury and property damage.
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 usu-
ally has the most uniform surface for wheel balancing.
Always center the wheel by the most uniform shaped
side of the hub to achieve the most accurate balance.
Regardless of mounting type, on standard units,
always make sure that the wheel is forced firmly against
the shaft faceplate and that the hub nut engages the
threaded shaft for at least four complete turns. To assist
in centering the wheel properly, rotate the wheel and
the shaft while tightening the hub nut.
Standard 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.
Figure 13 - Standard Back Cone Mounting
1.
Place the cone spring onto the balancer shaft with
the large end towards the faceplate.
2.
Select the cone that best fits the center hole in the
wheel. Slide the cone onto the shaft with the large end
towards the cone spring.
3.
Lift wheel onto the shaft and center it on the cone.
4.
Attach pressure cup to hub nut. Install the hub nut
assembly onto the shaft and tighten it securely against
the wheel. The wheel must be forced firmly against the
faceplate. The hub nut must engage the threads for at
least four full turns
Note: Use a nylon spacer (protective ring) to protect
custom wheel finishes.
Note: If the hub nut will not tighten completely, use
the front cone mounting method.
