If the wheel always stops in one position, provisionally
attach a balance weight [A] on the rim at the marking using
Rotate the wheel 1/4 turn [B], and see whether or not the
wheel stops in this position. If it does, the correct balance
weight is being used.
If the wheel rotates and the weight goes up, replace the
weight with the next heavier size. If the wheel rotates and
the weight goes down, replace the weight with the next
lighter size. Repeat these steps until the wheel remains
at rest after being rotated 1/4 turn.
Rotate the wheel another 1/4 turn and then another 1/4
turn to see if the wheel is correctly balanced.
Repeat the entire procedure as many times as necessary
to achieve correct wheel balance.
Permanently install the balance weight.
