- Check wheels for deformation, clacks and other damage. If deformed, remove wheel and check wheel runout.
- Remove tire from steel wheel and mount wheel on a tire balance machine.
- Set two dial indicators as shown in the illustration.
- Set each dial indicator to "0".
- Rotate wheel and check dial indicators at several points around the circumference of the wheel.
- Calculate runout at each point as shown below.
Axial runout (A) : ( +
)/2
Radial runout (B) : ( +
)/2
- Select maximum positive runout value and the maximum negative value. Add the two values to determine total runout.CAUTION:
In case a positive or negative value is not available, use the maximum value (negative or positive) for total runout.
Limit A: Refer to ROAD WHEEL . B: Refer to ROAD WHEEL . - If the total runout value exceeds limit, replace steel wheel.
