CHAPTER 11: CASTERS AND FORKS
Glide 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 - Standard Forks
Tools Needed:
•
Two Phillips Screwdrivers
1. Remove the two Allen screws, C Spring washers and axle that secure the caster to the fork. Use one Phillips
screwdriver to hold one screw in place and a second Phillips screwdriver to loosen the other screw. See
Figure 11-7.
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 Phillips screwdriver to hold one
screw in place and securely tighten the other screw with the second Phillips screwdriver.
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.
Replacing Casters - Slipstream Single-Sided Forks
To replace the casters, use the tools and follow the instructions under “Slipstream Single-Sided Forks – Replacing
Casters” on page 11-2.
