Cassette Removal

• 1). Set the wheel upright on the ground between your feet. Position the wheel so that the cassette is facing away from you.
  
  
• 2). Insert a bicycle free wheel removal tool through the center of the cassette.
  
  
• 3). Attach the chain-end of a chain whip to any one of the cogs contained within the cassette cluster. Hold the chain whip handle between the two- and three-o'clock positions.
  
  
• 4). Adjust a crescent wrench to fit onto the flat portion of the free wheel removal tool. Hold the handle of the crescent wrench at the nine-o'clock position.
  
  
• 5). Rotate the crescent wrench handle downward, loosening the cassette lock ring. Remove all tools, and unthread the cassette lock ring with your fingers.
  
  
• 6). Separate the cassette from the side of the wheel.
  
  

Sealed Bearing Removal

• 1). Use a flat head screwdriver to pry off any rubber seals protecting the cone and lock nut on the sides of the axle. These seals may be located on both sides.
  
  
• 2). Lay the wheel on its right, drive-side.
  
  
• 3). Slide the appropriate size cone wrench onto the flat portion of the left side cone. A cone will have two flat sides and will be located directly beside a lock nut.
  
  
• 4). Attach the crescent wrench to the lock nut. Turn the cone wrench and lock nut counterclockwise against the cone.
  
  
• 5). Unthread the lock nut and cone fully from the side of the axle. Lift the wheel carefully and slide the axle from the right, drive-side of the wheel.
  
  
• 6). Remove both bearing cartridges. There will be one cartridge on each side of the wheel. The cartridges resemble a small, metallic doughnut with a rubber seal.
