BALANCING WHEELS (ADHESIVE WEIGHT TYPE)

Preparation Before Adjustment

Remove inner and outer balance weights from the road wheel. Using releasing agent, remove double-faced adhesive tape from the road wheel.

CAUTION:

Wheel Balance Adjustment

  1. Set road wheel on balancer machine using the center hole as a guide. Start the balancer machine.
  2. For balancer machines that only have a clip-on (rim flange) weight mode setting, follow this step to calculate the correct size adhesive weight to use. When inner and outer imbalance values are shown on the balancer machine indicator, multiply outer imbalance value by 5/3 (1.67) to determine balance weight that should be used. Select the outer balance weight with a value closest to the calculated value above and install in to the designated outer position of, or at the designated angle in relation to the road wheel.
  1. Indicated imbalance value × 5/3 (1.67) = balance weight to be installed

Calculation example:

23 g (0.81 oz) × 5/3 (1.67) = 38.33 g (1.35 oz) ⇒ 40 g (1.41 oz) balance weight (closer to calculated balance weight value)

NOTE:

Note that balance weight value must be closer to the calculated balance weight value.

Example:

37.4 ⇒ 35 g (1.23 oz) 37.5 ⇒ 40 g (1.41 oz)


  1. Install balance weight in the position shown.

CAUTION:

CAUTION:

CAUTION:


CAUTION:

  1. If calculated balance weight value exceeds 50 g (1.76 oz), install two balance weight sheets in line with each other as shown.

CAUTION:

Do not install one balance weight sheet on top of another.

  1. Start balancer machine again.
  2. Install balance weight on inner side of road wheel in the balancer machine indication position (angle).

CAUTION:

Do not install more than two balance weights.

  1. Start balancer machine. Make sure that inner and outer residual imbalance values are 5 g (0.18 oz) each or below.
  2. If either residual imbalance value exceeds 5 g (0.18 oz), repeat installation procedures.

Allowable imbalance Refer to WT-54, "Road Wheel".
