CHAPTER 11: CASTERS AND FORKS

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.

Standard Forks

Replacing Casters

Tools Needed:

• Two #2 Phillips Head Screw Drivers

1. Remove the two Phillips Head screws, C Spring washers and axle. 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.

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 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.
