Inspection

ALUMINUM WHEEL

1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel runout.

1. Remove tire from aluminum wheel and mount wheel on a balancer machine.
2. Set dial indicator as shown.
3. Check runout, if runout value exceeds the limit, replace aluminum wheel.

Limit

Lateral Deflection (A) Refer to WT-54, "Road Wheel".

Radial Deflection (B) Refer to WT-54, "Road Wheel".

STEEL WHEEL

1. Check tires for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If deformed, remove wheel and check wheel runout.

1. Remove tire from steel wheel and mount wheel on a balancer machine.
2. Set two dial indicators as shown.
3. Set each dial indicator to "0".
4. Rotate wheel and check dial indicators at several points around the circumference of the wheel.
5. Calculate runout at each point as shown below.

Lateral deflection (A) = (W+X)/2

Radial deflection (B) = (Y+Z)/2

6. 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.

Limit

Lateral Deflection (A) Refer to WT-54, "Road Wheel".
