If the imbalance is 5 g or less, the zero
D
calibration is OK. Rebalance the wheel, then
go to Step 4 to check static balance.
If the imbalance is more than 5 g, go to Step
D
3.
3. Loosen the balancer wing nut, rotate the wheel
1/4 turn (90°), and retighten the nut. Recheck
the wheel balance.
If the imbalance is 5 g or less, the wheel may
D
not be centered on the balancer, or the
balancing cones, the cup, and/or wing nut are
damaged, dirty, or inappropriate for the wheel.
You may need to refer to the balancer
manufacturer's instructions to verify the correct
attachments. after making the necessary
corrections, recheck the wheel balance. If OK,
then go to Step 4.
If the imbalance is more than 5 g, the balancer
D
requires calibration. Contact the balancer
manufacturer for calibration by their repair
representative.
4. <<Static Balance Check>>
Attach a 5-g weight to the outer rim. Recheck
the balancer. The balancer should detect 5 ± 2
g of imbalance 170° to 190° away from both the
inner and outer 5-g weights.
WHEEL BALANCER CALIBRATION CHECKING FLOW CHART
Balance wheel.
Rotate wheel 1/2 turn.
Imbalance = 5 g or less
Rebalance wheel.
WHEEL AND TYRE -
Imbalance = more than 5 g
Rotate wheel 1/4 turn.
Imbalance = 5 g or less
Verify wheel is properly centered.
Verify cones, cup, & wing nut are clean,
undamaged, & appropriate for wheel.
Make necessary corrections, then
recheck wheel balance.
(Static balance Check)
Attach a 5 g weight to the outer rim.
Is the imbalance 5 ± 2 at 170°-190°
away from the 5-g weight?
(Dynamic Balance Check)
Attach a 5-g weight to the inner rim at
180° opposite the weight on the outer
rim. Is the imbalance 5 ± 2 g at 170°-190°
away from both 5-g weights?
Balancer dose not require calibration.
Troubleshooting
If the imbalance is within specification, the static
D
balance calibration is correct. Go to Step 5
to check the dynamic balance.
If the imbalance is out of specification, the
D
balancer requires calibration. Contact the
balancer manufacturer for calibration by their
repair representative.
5. <<Dynamic Balance Check>>
Attach a 5-g weight to the inner rim at 180°
opposite the 5-g weight that was added in step
4. Recheck the balance. The balancer should
detect 5 ± 2g of imbalance 170° to 190° away
from both the inner and outer 5-g weights.
If the imbalance is within specification, the
D
dynamic balance calibration is correct. The
balancer calibration checks are complete.
If the imbalance is out of specification, the
D
balancer requires calibration. Contact the
balancer manufacturer for calibration by their
repair representative.
