CHAPTER 8: AXLE PLATES AND CAMBER PLUGS
(CENTER OF GRAVITY; REAR SEAT HEIGHT)
All TiLite TR and YR wheelchairs are equipped with a camber tube (unless you have selected the optional Adjustable
Camber System). By adjusting the position of the camber tube, you can adjust the center of gravity of your chair.
This Chapter explains the various adjustments that are possible. The same adjustment will apply whether you have
an aluminum, titanium or carbon fiber camber tube. If your camber is 12°, 15° or 18° and you need to remove the
camber tube, you will need to remove the axle sleeve to allow the camber tube to slide out of the clamp or mount, see
“Adjusting Rear Wheel Spacing” on page 12-3.

WARNING
Any changes to the position of the camber tube will affect the stability of the chair. Use extreme caution when using a
new camber tube position as the new position may make the chair more prone to tip over.
If you ignore this Warning,
your chair may not perform properly, which in turn, may cause you to fall, tip over or lose control of the chair and
seriously injure yourself or others or damage the chair.

WARNING
Whenever you adjust the position of the camber tube (either to adjust the rear seat height or the center of gravity), it
may be necessary to adjust the toe-in/toe out of the rear wheels. See “Adjusting Toe-In/Toe-Out” on pages 8-3 and
8-4. In addition, whenever you adjust the position of the camber tube or when you adjust the toe-in
If you ignore this
Warning, your chair may not perform properly, which, in turn, may cause you to fall, tip over or lose control of the chair
and seriously injure yourself or others or damage the chair.
Note:
It is recommended that you remove the rear wheels and turn the chair upside down before attempting to make
any adjustments described in this Chapter. A padded surface will help protect the frame’s finish.

Adjusting the Center of Gravity
(TR and YR Series 2)
Tools Needed:
• 3/16” Allen Wrench
• Ruler
1. Remove the rear wheels.
2. Loosen, but do not remove, the six Allen screws (three on each side of the chair) that secure the camber clamps
and camber tube mounts to the frame. See Figure 8-1.
3. Simultaneously slide both camber tube clamping assemblies forward and rearward along the frame until they are
positioned in the desired location. Use a ruler to ensure both camber tube clamping assemblies are the same
distance from the rear of the frame (measured from the rear of the frame to the top of the clamping assembly).
See Figure 8-2.
4. Securely tighten the six Allen screws that secure the axle clamps and camber tube mounts to the frame.
5. Reinstall the rear wheels.
