3.2. Wheel Balancing See figs. 2, 3, 4 & 5

3.2.1. Use the standon a stable, level surface. If necessary
adjust the feet until frame is level.

3.2.2. Slide the spindle through the motorcycle
wheel hollow axle and slide a cone onto either end of the
spindle so that the tapered ends enter the wheel bearings.
When the wheel is central on the spindle, secure the cones
by tightening the grub screw in each using a 3mm hex key.
Check that the wheel is central on the spindle and firmly
secured by the cones for best results, see fig.4.

3.2.3. With the wheel securely on the stand, gently rotate the wheel.
When the wheel settles, the spot at the bottom of the wheel is
the heavy spot.

3.2.4. Now with the heavy spot at the bottom mark the top of the
wheel directly opposite the heavy spot using chalk or
adhesive tape. This is the light spot, see fig.5A.

3.2.5. Gently spin the wheel again to ensure that the heavy spot will
again settle at the bottom, see fig.5.

3.2.6. Attach some wheel weights to the rim of the wheel at the
light spot (fig.5A) and spin the wheel gently.

3.2.7. If the light spot falls to the bottom, too much weight has
been added to the wheel. If the heavy spot falls to the bottom,
not enough weight has been added to the wheel. Add /
Remove weight as required, see fig.6.

3.2.8. Turn the light spot 90 degrees so it sits horizontally with the
heavy spot and observe its movements, if again it falls to the
bottom, too much weight has been added, if the heavy spot
falls, too little weight has been added, see fig.6.

3.2.9. Repeat until the light spot and heavy spot are on a horizontal
line through the centre of the wheel. Once this has been
achieved the wheel should rest still at any position through
the wheels circumference.

3.3. Wheel Truing See fig.3

3.3.1 Use the threaded centring bolts to securely hold the wheel whilst truing the rim.

3.3.2. Tools Required:
Spoke wrench (Sealey MS037)
Spoke torque wrench
Dial gauge (optional)

3.4. Lateral Run Out

3.4.1. Spin the wheel to see if there is Lateral Run Out.

3.4.2. Loosen the nut on the pointer and set it as close to the wheel as possible.
Note: Only tighten spokes in quarter turn increments.

3.4.3. If the spinning wheel moves close to the pointer at some point, tighten the spokes on the opposite side to move the wheel rim away
from the pointer.

3.4.4. If the wheel moves away from the pointer, tighten the spokes on the side nearest the pointer.
Note: the severity of the run out determines how many spokes (usually) three and how many turns are made.

3.4.5. Continue adjusting until the run out has gone from the wheel. Check manufacturer's data for run out tolerances.
