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

Place the cone spring onto the balancer shaft with

the large end towards the faceplate.

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.

Lift wheel onto the shaft and center it on the cone.

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.
