Adjusting Toe-In / Toe-Out

Tools needed:
1. 4mm Hex Wrench
2. 23mm Open End Wrench
3. Ruler or Tape Measure
4. Felt Tip Pen
Note: Adjusting toe-in / toe-out does not apply to wheelchairs with 0° camber; however, it is still necessary to make sure that the camber plug flats are
perpendicular to the ground.
1. Make sure the distance from the end of the camber tube to the camber tube bracket is identical
on both sides of the wheelchair.
2. Make sure the rear wheels are properly inflated.
3. Place the wheelchair on all four wheels with the casters trailing toward the rear of the frame.
4. Measure from the floor to the center of the axle ("Measurement A"). Ensure the tape
measure / ruler is perpendicular to the floor.
5. Fix the wheelchair so that it cannot roll forward or backward (do not use the wheel locks
as this may affect the toe-in/toe-out adjustment).
6. Measuring from the floor at the rear of each tire, mark the tire with washable marker at the
same height as Measurement A.
7. Measuring from the floor at the front of each tire, mark the tire with washable marker at the
same height as Measurement A.
8. From behind the wheelchair, measure the horizontal distance between the left and right tires
at the rear reference marks made in Step 6.
9. Measure the distance between the left and right tires at the front reference marks made in Step 7.
10. Compare the two measurements. If the measurements in Steps 8 and 9 are the same (within 1/8"), no toeing adjustment is needed, skip to Step 13.
If not, proceed to Step 11.
11. Loosen the bottom clamp screws in each camber tube bracket that secures the camber tube in place.
12. If the measurement in Step 9 is less than the measurement in Step 8, rotate the camber tube rearward to toe-out the rear wheels. The 23mm open end
wrench can be used to rotate the camber tube if it will not rotate by hand. If the measurement in Step 9 is greater than the measurement in Step 8, rotate the
camber tube forward to toe-in the rear wheels. Continue adjusting the camber tube until these two measurements are equal.
13. Securely tighten the bottom clamp screws in the camber tube bracket.
