Quick-Release Axles - Invacare 9000 Jymni Pediatric Series Maintenance Manual

SECTION 7—REAR WHEELS

Quick-Release Axles

NEVER use quick-release axles on the recliner.
NOTE: For this procedure, refer to FIGURE 7.2.
NOTE: If replacing the same size rear wheel, note the mounting position on the wheelchair frame
for proper reinstallation of the new rear wheel.
1. Push the dentent pin in the tip of the quick-release axle (with wheel) and pull the axle
out through the opening in the center of the rear wheel and axle spacer.
2. Push the detent pin in the tip of the quick-release axle again and pull the axle out of
the rear wheel.
3. Repeat STEPS 1-2 for the opposite rear wheel.
4. To reinstall the rear wheel onto the wheelchair, reverse STEPS 1-3.
Make sure the detent pin and detent balls of the quick-release axle are fully released
before operating the wheelchair.
The detent balls MUST be protruding past the inside of the rear wheel axle bushing
for a positive lock (Detail "A").
Keep detent balls clean.
Invacare recommends inserting quick-release axles with the detent pin to the inside
of the wheelchair to prevent accidental release during contact activities.
5. If the detent balls are not protruding past the inside of the axle bushing or there is too
much side-to-side movement of the rear wheel assembly, refer to Adjusting the
Quick-Release Axle on page 48.
