Front Casters and Forks
(ZR Series, Aero Z, TR and YR)
WARNING
Always mount identical size front 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.
Note: The following instructions apply with respect to
all 3”, 4”, 5” and 6” front casters. See Figure 105.
Replacing Front Casters
Tools Needed:
• Two #2 Phillips Head Screw Drivers
1. Remove the two Phillips head screws and axle that
secure the front caster to the fork. Note: It will be
necessary to use one Phillips head screw driver to
hold one screw in place and a second screw driver
to loosen the other screw. See Figures 107 and
108.
2. Remove the front caster and fork spacers from the
fork.
3. Install the new front caster and fork spacers onto
the fork and securely tighten the two screws so
there is no space between the front caster, the fork
spacers and the fork sides. Note: It will be
necessary to use one Phillips head screw driver to
hold one screw in place in order to be able to
securely tighten the other screw with the second
screw driver.
WARNING
The threads on the screws that secure the front
casters to the fork have been treated with a medium
strength threadlock to reduce the possibility they will
become loose. You should be able to remove and
reinstall these screws two or three times without
reapplying threadlock to these screws. If you
repeatedly remove and reinstall these screws, TiLite
requires that you reapply a medium-strength
threadlock after every second adjustment.
