CHAPTER 8: AXLE PLATES & CAMBER PLUGS (CENTER OF GRAVITY;
REAR SEAT HEIGHT)
3. Reposition the camber clamp to the desired height, making sure that the locating pin on the inside of the clamp is
secured inside one of the notches on the axle plate. See Figure 8-4. Note that the notches in the axle plate are spaced
in approximately 5/16” increments.
4. Reinstall the two hex bolts that secure the camber clamp to the axle plate, making sure all washers are reinstalled in the
exact same order as they were originally installed. Initially each hex bolt should be finger-tight. See Figure 8-3.
5. The two hex bolts should be tightened to 30 ft-lbs. in order to insure that the back wheel is properly toed, it is important
to tighten these bolts as follows:
a. Alternating between the forward and rearward hex bolts. Use the torque wrench to turn each bolt approximately
one-half turn. Continue alternating until each bolt has been tightened to 30 ft-lbs.
b. Visually inspect the gap between the non-threaded camber clamp and the threaded camber clamp both forward
and rearward of the axle plate.
c. If necessary, use the torque wrench to tighten down the side where the gap described above is larger.
6. Repeat Steps 3 and 4 with the camber clamp on the opposite side of the chair. Make sure the second camber clamp is
mounted in exactly the same location on the opposite side of the frame.
7. Securely tighten all four hex bolts.
8. Using a level, make sure that the flats on each camber plug are perpendicular to the ground. If necessary, loosen the
two Allen screws that secure the camber plug with the camber clamp and rotate the camber plug within the clamp to
ensure that the flats are perpendicular to the ground. See Figure 8-5.
9. Reinstall the rear wheels.
10. Check the toe-in/toe-out and adjust as needed and square the casters as needed.
11. Adjust the wheel locks.
Note
: If the preceding procedure does not permit you to achieve your desired rear seat height, consider utilizing one of the
other configurations shown in Figure 8-1. For example, if your chair was delivered in the configuration shown in Figure 8-1A
but you want the rear seat height while maintaining the same center of gravity, then switch the left and right camber mount
clamps so as to achieve the configuration shown in Figure 8-1C.
