Balance wheel.
Rotate wheel 1/2 turn.
Imbalance = 5 g (0.18 oz) or less Imbalance = more than 5 g (0.18 oz)
Rebalance wheel.
Rotate wheel 1/4 turn.
Imbalance = 5 g (0.18 oz) or less Imbalance = more than 5 g (0.18 oz)
Verify wheel is properly centered.
Verify cones, cup, and wing nut are clean,
undamaged, and appropriate for wheel.
Make necessary corrections, then recheck
wheel balance.
Attach a 5 g (0.18 oz) weight to the outer rim.
Is the imbalance 5 ± 2 g (0.18 ± 0.06 oz) at 170
–
190
degree angle away from the 5 g (0.18 oz) weight?
YES NO
Attach a 5 g (0.18 oz) weight to the inner rim at 180
degree angle opposite the weight on the outer rim.
Is the imbalance 5 ± 2 g (0.18 ± 0.06 oz) at 170
–
190
degree angle away from both 5 g (0.18 oz) weights?
YES NO
