Tools Needed:
• 9/16” Socket Wrench
I
WARNING
On the ZR Series, the fork stem is permanently installed in the “Bullet” Caster Housing. Do not attempt to unscrew
the fork stem or the set screw. If it should become necessary to replace the fork stem on these chairs, this repair
can only be performed by TiLite at our factory.
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.

WARNING
On the Aero Z Series 1 and ZRA Series 1, the fork stem is permanently installed in the “Bullet” Caster Housing. If
it should become necessary to replace the fork stem, you will need to order the “Bullet” Caster Housing/fork stem
assembly.
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.
1. Remove the casters. See “Replacing Casters” on page 11-1.
2. Loosen and remove the nylock nut and washer that secure the fork to the fork stem. See Figures 11-1 through
11-5.
3. Remove the old fork and caster cap and install the replacement fork and old caster cap on the fork stem.
4. Replace the nylock nut and washer and securely tighten.
5. Reinstall the casters. See “Replacing Casters” on page 11-1.
SLIpSTREAM SINGLE-SIDED FORK
Replacing Casters
Tools Needed:
• 1/8” Allen Wrench
1. Remove the Allen screw and caster cap from the caster. See Figures 11-6 and 11-7.
2. Remove the caster from the Single-Sided Fork.
3. Install the new caster onto the Single-Sided Fork, replace the single-sided caster cap and securely tighten the
screw so there is no space between the caster and the Single-Sided Fork side. If you have Performance casters
be sure the “dish” of the caster faces outward as the fork is trailing rearward.
Note: If you are replacing your casters with a wider caster, you must replace the axle with a longer axle.
Likewise, if you are replacing your wide caster with a smaller width caster, make sure you also order the shorter axle.
I
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.
