12  Removing & Installing Rear 

Wheels 

 
1)  Place the wheelchair on blocks or a safety stand so that the rear wheels are 

off of the ground. NOTE: If replacing with the same size wheels, make a note 
of the mounting position on the wheelchair for proper reinstallation of the new 
rear wheels. 

 
2)  Remove the dust cap from the axle (if applicable), bolt, locknut and washer 

that secure the rear wheel and axle spacer to the wheelchair.   

 

 

 
3)  Repeat STEP 2 for the opposite rear wheel. 
 
4)  To reinstall the rear wheel onto the wheelchair, reverse STEP 2. 

NOTE: Make sure the axle spacer is properly placed between the rear wheel 
and wheelchair frame. 

 
5)   Replacing the rear tire or tube will require professional assistance. 
 
 

     

WARNING 

After adjustments, service or repair, make sure attaching hardware is 
securely tightened. Otherwise, injury or damage may occur.
