Replacing/Installing Front Caster Assemblies

The seat height, seat depth, back angle, pivot point of seat frame, seating system, caster
position, size and position of the rear wheels, as well as the user condition directly relate
to the stability of the wheelchair. Any change to one or any combination of the nine
may cause the wheelchair to decrease in stability. These adjustments MUST be
performed by a qualified technician.
NOTE: For this procedure, refer to FIGURE 8.1.
1. Remove the mounting screw, spacers and locknut that secure the front caster to the
fork.
2. Remove the front caster from the fork.
NOTE: If replacing a front caster on a six or eight inch front fork, note the mounting position of
the existing front caster for installation of the new front caster.
NOTE: If repositioning front casters on a six or eight inch front fork, Invacare recommends that
this procedure be performed by an authorized Invacare dealer or qualified technician.
