Steel Wheel
- Check tires for wear and improper inflation.
- Check wheels for deformation, cracks 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 figure.
- 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.
Radial runout = (A + B)/2
Lateral runout = (C + D)/2
- Select maximum positive runout value and the maximum negative value.
Add the two values to determine total runout.
In case a positive or negative value is not available, use the maximum value (negative or positive) for total runout.
If the total runout value exceeds the limit, replace steel wheel.
