Operating the Balancer

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 

usually has the most uniform surface for wheel bal-

ancing. 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.

Standard Back Cone/Collet 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.

1.

 Select the cone/collet that best fits the center 

hole in the wheel. Slide the cone/collet onto the shaft 

with the large end towards the cone spring.

2.

 Lift wheel onto the shaft and center it on the 

cone/collet.

3.

 Attach the pressure cup to the 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.
