CHAPTER 11: CASTERS, FORKS AND CASTER PIN LOCKS
Casters and Bearing Forks
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 #2 Phillips Head Screw Drivers
1. Remove the two Phillips head screws, C Spring washers and axle that secure the caster to the fork. Use one screw
driver to hold one screw in place and a second screw driver to loosen the other screw. See Figure 11-1.
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 screw driver to hold one screw in place and
securely tighten the other screw with the second screw driver.
Note:
If your chair has 4” or 5” TiLite Litespeed 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.

WARNING
The threads on the screws that secure the casters to the fork are treated with Vibra-TITE
®
VC-3, a locking and sealing
coating, to reduce the possibility they will become loose. You should be able to remove and reinstall these screws
approximately four times without reapplying the coating. If you repeatedly remove and reinstall these screws, TiLite requires
that you reapply Vibra-TITE
®
VC-3 after every fourth adjustment.
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.
