<Confirming Proper Balance>
1. After balancing the wheel, loosen the wing nut
and turn the wheel 180
°
against the balancer's
hub. Then re-tighten the wing nut and check the
balance again. Repeat wheel balance if
necessary.
2. Turn the wheel again 180
°
against the balancer's
hub. If the wheel becomes out-of-balance each
time it is turned against the balancer's hub, the
wheel balancer may require calibration.
<Wheel Balancer Calibration Checks>
1. Mount an undamaged original-equipment alloy
rim and tyre assembly (wheel) onto your
off-the-car wheel balancer. Balance the wheel.
2. <<Zero Calibration Check>>
Loosen the balancer wing nut, rotate the wheel a
half-turn (180
°
), and retighten the nut. Recheck
the balance.
•
If the imbalance is 5g or less, the zero calibration
is OK. Rebalance the wheel, then go to Step 4 to
check static balance.
•
If the imbalance is more than 5g, go to Step 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 5g or less, the wheel may not
be centred 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 5g, the balancer
requires calibration. Contact the balancer
manufacturer for calibration by their repair
representative.
4. <<Static Balance Check>>
Attach a 5g weight to the outer rim. Recheck the
balancer. The balancer should detect 5
±
2g of
imbalance 170 to 190
°
away from the 5g weight.
•
If the imbalance is within specification, the static
balance calibration is correct. Go to Step 5 to
check the dynamic balance.
•
If the imbalance is out of specification, the
balancer requires calibration. Contact the
balancer manufacturer for calibration by their
repair representative.
5. <<Dynamic Balance Check>>
Attach a 5g weight to the inner rim at 180
°
opposite the 5g 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 5g weights.
•
If the imbalance is within specification, the
dynamic balance calibration is correct. The
balancer calibration checks are complete.
•
If the imbalance is out of specification, the
balancer requires calibration. Contact the
balancer manufacturer for calibration by their
repair representative.
