Wheelchair Repair and Maintenance: Keeping Your Mobility on Track

Wheelchairs — whether standard folding chairs, lightweight models, or complex tilt-in-space systems — are precision mobility devices. Regular maintenance prevents small problems from becoming mobility-limiting breakdowns, and timely repair keeps users safe and independent.

Common Wheelchair Problems

Flat or Worn Tires

Pneumatic (air-filled) tires are the most common failure point. Check tire pressure monthly — most require 75–100 PSI. Flat tires make propulsion significantly harder and increase fall risk. OB1 carries replacement tubes and tires for most standard wheelchair tire sizes. Foam-filled tire upgrades eliminate flats entirely.

Wobbly or Misaligned Wheels

Side-to-side wheel wobble indicates a bent axle or damaged wheel hub. Front casters that constantly shimmy are often caster forks that need adjustment — a common and inexpensive fix.

Footrest and Armrest Issues

Footrests that sag or don’t swing away cleanly have worn adjustment mechanisms. Armrests that are loose have worn plastic bushings or lock pins. Both are straightforward repairs with available replacement parts.

Seat and Back Upholstery

Worn or torn upholstery affects both comfort and positioning. Replacement upholstery for most standard folding chairs is a quick swap that can extend a chair’s useful life significantly.

Monthly Maintenance Checklist

• Check and inflate tires to recommended pressure
• Inspect all bolts and axle nuts for tightness
• Test wheel locks (apply and verify chair doesn’t roll)
• Check footrests and armrests for secure operation
