WHEEL BALANCE ADJUSTMENT (ALUMINUM ALLOY WHEEL)

2016 – MX-5 – Suspension

CAUTION:

Perform the wheel balance adjustment on the outer side first, then the inner side.
Be careful not to damage the wheel.
Use genuine balance weight.

1. Remove the balance weight from the wheel.

2. Remove the double-sided adhesive tape left on the wheel and remove any grease and dirt from the affixing surface.

3. Set the wheel to the wheel balancer and measure the unbalance amount and balance weight affixing position using the clip type balance weight mode.

4. Calculate the weight of the balance weight by multiplying 1.6 to the measured unbalance amount.

Example of balance weight calculation (unbalance amount displayed on wheel balancer: 23 g {0.81 oz})

5. Select the balance weight so that the weight is nearest to the calculated value (weight).

NOTE:

Select the balance weight so that the weight is nearest to the calculated value.

Ex.1) 32.4 g {1.14 oz} (calculated value) = 30 g {1.06 oz} (weight of balance weight to be selected)
Ex.2) 32.5 g {1.15 oz} (calculated value) = 35 g {1.23 oz} (weight of balance weight to be selected)

6. Affix the selected balance weight to the balance weight affixing position (outer side) displayed by the wheel balancer.

CAUTION:

Completely affix the balance weight by pressing it with 25 N {2.5 kgf, 5.6 lbf} or more of force per 5 g {0.2 oz} for 2 s or more.
Do not install three or more balance weights.
Do not affix the balance weights in parallel or stack them.
The total weight of all the balance weights must be 160 g {5.64 oz} or less.

When affixing two balance weights, affix one on the left and the other on the right centering the balance weight affixing position displayed on the wheel balancer.

1. Measure the unbalance weight and the balance weight clipping point using the wheel balancer.

2. Select the balance weight equivalent to the measured unbalance amount (weight).

NOTE:

Select the balance weight so that the weight is nearest to the calculated value.

Ex.1) 32.4 g {1.14 oz} (calculated value) = 30 g {1.06 oz} (weight of balance weight to be selected)
Ex.2) 32.5 g {1.15 oz} (calculated value) = 35 g {1.23 oz} (weight of balance weight to be selected)

3. Install the selected balance weight to the balance weight clipping position (inner side) displayed on the wheel balancer.

CAUTION:

Do not install three or more balance weights.
The weight of one balance weight must be 60 g {2.1 oz} or less, and the total weight of two balance weights must be 100 g {3.53 oz} or less.

1. After installing the balance weights on the outer and inner sides, measure the wheel balance again. Standard
