Important: Always read and follow instructions.

Mounting Wheel On Spindle Shaft

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, 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.

CAUTION

Failure to tighten the hub nut properly may
result in the wheel dismounting, causing
personal injury and property damage.

Standard Back Cone Mounting

Most original equipment and steel wheels can be

mounted properly using this method. The wheel is cen-

tered on a cone from the inner side of the hub.

Figure 8 - Back Cone Mounting

Select the cone that best fits the center hole in the

wheel. Slide the cone onto the shaft with the large end

towards the faceplate.

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

Attach the pressure cup to the hub nut and install

the assembly onto the shaft. Tighten securely.

Note: Use a nylon spacer (no mar ring) to protect cus-

tom wheel finishes.

Thread the hub nut onto the shaft, and tighten it

against the wheel. The wheel must be forced firmly

against the faceplate. The hub nut must engage the

threads for at least three full turns.

Note: If the hub nut will not tighten completely, use

the front cone mounting method.
