Installation and Operation
Installing the Jaw Drive Bar and Spindle
1. If equipped, remove the threaded stub shaft from
the balancer using a 3/4” wrench.
2. Make sure the faceplate and motor shaft are clean,
then place the jaw drive bar onto the motor shaft
and secure it to the faceplate with the 3/8-16
socket cap screws provided. Tighten the screws.

3. Clean the threads and mating surfaces on the end
of the motor shaft where the threaded stub shaft
or motorcycle spindle will be installed.
4. Thread the 14mm spindle into the motor shaft and
tighten with the provided hex wrench.

Mounting a Motorcycle Wheel
Always try to use the stepped bearing adapters when
mounting wheels. Use the tapered cones only if none
of the stepped adapters provides an exact fit into the
wheel bearings.
1. If the wheel and drive assembly is too wide to fit
on the spindle, remove any sprocket or drive shaft
cushion hubs. Remove any axle spacers if they
came off the axle with the wheel.
2. Find the stepped adapter or tapered cone that best
fits the wheel.

Cone
3. Slide the adapter or cone onto the spindle, large
end first.
4. Slide the wheel onto the spindle and guide it over
the previously installed adapter or cone.
5. Slide the other matching adapter or cone onto the
spindle and into the wheel bearing.
6. Slide the spacers onto the spindle as necessary so
the spindle nut can be tightened. Install the spindle nut and tighten by hand only.

7. Rotate the adapter so that one of the lock jaws is
facing the front of the balancer. Lift the stopper
from its holding position and allow the lock jaw to
come into contact with the wheel.
8. Repeat step 7 for the other lock jaw.
