11.11Determining/Setting Toe In/Toe Out

For this procedure, refer to FIGURE 12 on page 74 and FIGURE 14.

1.Inflate all pneumatic tires to recommended tire pressures (listed on the sidewall of the tire).

2.Measure the distance between the centerlines at the rear and front of the rear wheels at approximately 12 inches (for 24-inch diameter wheels) from the ground/floor (FIGURE 14).

3.Determine difference between two measurements. If difference between the two measurements is greater than 1/8 inch, one of two conditions exists:

If the back centerline measurement of the rear wheels is SMALLER than the front centerline measurement of the rear wheels, a TOE-OUT condition exists (FIGURE 14).

If the back centerline measurement of the rear wheels is LARGER than the front centerline measurement of the rear wheels, a TOE-IN condition exists (FIGURE 14).

4.If the difference between the measurements is greater than 1/8-inch, correct the toe-in/toe-out condition by performing the following:

A.Loosen both mounting socket head clamp screws (FIGURE 12).

B.Rotate the camber tube until front and rear measurement are within 1/8-inch (FIGURE 12).

C.Securely tighten both socket head clamp screws (FIGURE 12).
