Determining Toe In/Toe Out - Invacare Crossfire T6 Owner's Operator And Maintenance Manual

Determining Toe In/Toe Out

NOTE: For this procedure, refer to FIGURE 8.13.
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 from the ground/floor (FIGURE 8.13).
NOTE: For optimum accuracy, perform STEP 2 with the wheelchair occupied.
3. Determine difference between two measurements. If difference between the two
measurements is greater than ½‐inch (0 + ¼‐inch for maximum rollability), 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 8.13).
• 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 8.13).
4. If the difference between the measurements is greater than ½‐inch, correct the
toe‐in/toe‐out condition.
