Repair or Replace your Bearings

If after being cleaned and repacked the bearings still do not move easily, you will have to replace

either the balls or the whole bearing.

Sealed bearings in rear wheel hub and caster barrel: If the bearing still does not move easily after

being thoroughly cleaned, replace the entire bearing.

Front wheel bearings (bicycle bearings):

Replace balls if broken or cracked. If the

wheel still does not move easily, inspect

cup and cone for damage. If the surfaces

that the balls roll on are obviously rough,

these parts should be replaced. If you need

help, a bicycle mechanic should be able to

do this.

Upholstery

Upholstery that is worn unevenly or otherwise damaged can be dangerous as it:

• Can cause uneven pressure on your buttocks or legs.

• Can cause you to sit in an uncomfortable position.

• Can rip suddenly and cause you to fall out of the chair.

By inspecting your upholstery regularly you will know when you need to replace your

upholstery. Your upholstery will not last as long as the wheelchair and will have to be replaced

over time. Make sure all bolts or screws that hold the upholstery in place are there. Replace any

missing bolts to make your upholstery last longer and prevent injury from upholstery failure.

It is important to keep the upholstery clean and dry because dirt and moisture (sweat, food,

drink, dust, mud, or other substances) can cause the upholstery to wear more quickly or rot. Soil

(dust/mud/etc.) can contain abrasive materials which may wear the upholstery away and cause it

to wear out much more quickly than if it is kept clean. Moisture can cause the upholstery to rot

and the fasteners, which hold the upholstery to the frame, to rust. If the upholstery stays wet it

can also stretch.
