CHAPTER 11: CASTERS AND FORKS
5. Make sure your footrest is set to your desired seat-to-footrest measurement, and, using a ruler, make sure the left
and right sides of the footrest are the same distance to the level surface.
6. If the above adjustments correct the oater, securely tighten all Allen screws loosened in Steps 3 and 4. If not,
proceed to Steps 7 through 9.
7. While applying gentle downward pressure on the top of the oating caster barrel, securely tighten the Allen screw
in the footrest binder clamp on that side of the chair.
8. Securely tighten all Allen screws on the camber tube clamps, starting with the screws that secure the camber tube
to the camber tube clamp (do not start with the screws that secure the clamp to the frame).
9. Check to make sure all of the wheels are at on your level surface and that neither caster is “oating.” If all
wheels are at and you have no oaters, securely tighten the remaining screws. If you still have a oating caster,
proceed to Steps 10 through 13.
10. Loosen, but do not remove, the Allen screw on the footrest binder clamp only on the side of the chair with the
oating caster.
11. Place a wood block under the other caster wheel (which is not oating) as shown in Figure 11-8.
12. Apply gentle downward pressure on the caster wheel that is oating. It is advisable that you have an assistant to
place downward pressure on the opposite side of the chair at the backrest when making this adjustment.
13. Remove the wood block and check to see if the caster still oats. If the caster no longer oats, securely tighten
the Allen screw on the footrest binder clamp. If the caster still oats, or if the other caster starts to oat, repeat
Steps 10 through 13 until the caster no longer oats.

I WARNING
Always mount identical size casters and forks on both sides of your chair. If you ignore this Warning, you may fall, tip
over or lose control of the wheelchair and seriously injure yourself or others or damage the wheelchair.
Replacing Casters
Tools Needed:
• Two 5/32” Allen Wrenches
1. Remove the two Allen screws, C Spring washers and axle that secure the caster to the fork. Use one Allen
wrench to hold one screw in place and a second Allen wrench to loosen the other screw. See Figure 11-10.
2. Remove the caster and spacers from the fork.
3. Install the new caster, spacers and C Spring washers onto the fork and securely tighten the two screws so there
is no space between the caster, the spacers and the fork sides. Use one Allen wrench to hold one screw in place
and securely tighten the other screw with the second Allen wrench.
Note: If your chair has 4” or 5” TiLite performance casters, make sure that Spacer 2 (which is wider than Spacer 1) is
positioned on the recessed side of the caster, which should be oriented outwards when the casters are in the trailing
position.
