Installing/Replacing Six or Eight-Inch Front Casters and
Forks
If converting from a six-inch caster to an eight-inch caster or vice versa, there are
seat-to-floor height adjustments that must be made. Therefore, this procedure
MUST be performed by a qualified technician.
NOTE: For this procedure, refer to FIGURE 8.1.
NOTE: This procedure can be performed if replacing the exact same size front caster.
1. Remove the dust cover.
2. Remove the locknut that secures the fork to the caster headtube.
3. Drop the front caster and fork out of the caster headtube.

4. Slide in the new six/eight-inch front caster and fork.
5. Reassemble by reversing STEPS 1-3.

following check:
A. Tip back of wheelchair to floor.

immediately rest in a straight downward position).
