CHAPTER 8: AXLE PLATES AND CAMBER PLUGS
(CENTER OF GRAVITY; REAR SEAT HEIGHT)
4. Measure from the floor to the center of the axle (“Measurement A”). Be sure the tape measure/ruler is
perpendicular to the floor.
5. Block the wheels with a heavy object so the chair can not 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 a felt tip pen) at the same height as
Measurement A.
7. Measuring from the floor at the front of each tire, mark the tire (with a felt tip pen) at the same height as
Measurement A.
8. Measure the distance between the left and right tires at the rear reference marks made in Step 6. See Figure
8-10.
9. Measure the distance between the left and right tires at the front reference marks made in Step 7.
10. If the measurements in Steps 8 and 9 are the same (within 1/8”), no toeing adjustment is needed, and you may
skip to Step 13. If not, proceed to Step 11.
11. Loosen the Allen screw in each camber clamp 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 using the 7/8” Open
End wrench rearward to toe-out the rear wheels. If the measurement in Step 9 is greater than the measurement
in Step 8, rotate the camber tube using the 7/8” Open End wrench forward to toe-in the rear wheels. Continue
adjusting the camber tube until these two measurements are equal. See Figure 8-11.
13. Securely tighten the Allen screws in the camber tube clamp.
