10. Slide the new axle tube through the other camber clamp until the end of the axle tube is flush with the outside of the
camber clamp.
NOTE: DO NOT close the quick‐release levers or tighten the socket screws that secure the axle tube to the camber clamps at this time.
NEVER position the camber inserts in the axle tube with more than 3-inches (12 indexing marks
showing) of the camber insert outside of the axle tube. Otherwise, the camber inserts will not be
securely tightened in the axle tube resulting in possible injury to the user or damage to the
wheelchair.
11. Install the rear wheels and camber inserts into the new axle tube and slide the camber inserts to the position noted in
STEP 1. Make sure there are no more than 3‐inches (12 indexing marks) of the camber inserts outside of the axle tube.
12. Slide the indexing ring on the camber insert until it is flush with the camber clamp.
NOTE: Before using the wheelchair, make sure both camber inserts are set to the same indexing notch. This will make sure the distance
between the rear wheel and the wheelchair is the same on both sides.
13. Adjust the axle tube. Refer to Adjusting The Axle Tube on page 31.
NOTE: The performance of the wheelchair will be affected if the axle tube has not been adjusted to correct the toe in/toe out of the
wheelchair.
14. Ensure the camber clamps are closed. Refer to Opening/Closing Camber Clamps on page 27.
