Bugaboo Cameleon 3 Wheel Bearing Replacement Tools & Guide

Clear, step-by-step instructions for replacing front and rear wheel bearings on the Bugaboo Cameleon 3 stroller. Includes parts, tools, and assembly steps.

Bill of Materials (BOM):

1. Front Wheels:
   • 608-2RS ball bearings – 4 pcs (2/wheel) (also available in stainless)
   • M8 washers (DIN125) – 20 pcs (10 per wheel) (find in any hardware store)
2. Rear Wheels:
   • 6900-2RS ball bearings – 4 pcs (2/wheel) (also available in stainless)

I recommend Kugellager-Express for quality ball bearings, competitive prices, and professional service—perfect for reliable DIY parts.

Tools Needed:

• Two  4mm Allen keys
• M8 screw or Ø8mm Pin (at least 70 mm long)
• Thin-tipped pliers
• Flat screwdriver
• Hammer
• Printed parts
  • “Wheel Support" - Front Wheels
  • "Spacer" - Rear Wheels
  • "Impact Pad"  - Rear Wheels

Instructions:

Front Wheels Replacement

1. Remove Pin Screw
   • Use two 4mm Allen keys to unscrew the pin screw. Remove the pin screw.
2. Remove the Pin
   • Place the wheel on top of the "Wheel Support".
   • Use an M8 screw or Ø8mm Pin(at least 70 mm long) to push the pin out of the wheel. Use a hammer if needed.
   • 
   • Caution: Do not damage the pin threads.
3. Remove Bearings
   • Separate the wheel parts. Use the Pin or a flat screwdriver to carefully pry out the old bearings.
   • 
4. Clean all parts
   • Clean each part. Do not use acetone (it can damage the rubber seals on the new bearings amongst other things).
   • 
5. Prepare New Bearings
   • Insert two 608-2RS ball bearings and 10 M8 washers into each wheel (5 on each side of the wheel as spacers). Note: New washers replace the built-in spacer of the old bearings.
   • 
6. Reassemble the Wheel
   • Insert the pin partway into the wheel, and place 5 M8 washers onto the pin.
   • Insert the wheel and push the pin further until the pin tip is visible on the opposite side.
   • Use thin-tipped pliers to insert the remaining 5 M8 washers one at a time.
   • 
7. Tighten the Pin
   • Push the pin fully into place. Insert and tighten the pin screw with two Allen keys.
   • Repeat Steps 1-6 for the second wheel if necessary.

Rear Wheels Replacement

1. Remove the Push-On Lock Washer
   • Use a flat screwdriver to carefully pry off the lock washer.
   • If the teeth bend, carefully bend them back to their original shape.
2. Remove the Shaft and Bearings
   • Pull out the shaft. Use a screwdriver or the shaft to pry out the old bearings. 
   • 
   • Note: The old bearings have built-in spacers, but you can replace them with two 6900-2RS bearings per wheel.
3. Clean All Parts
   • Clean each part. Do not use acetone (it can damage the rubber seals on the new bearings).
4. Reassemble Rear Wheel Assembly
   • Place the "Spacer" into the "Wheel Support".
   • 
   • Position the wheel assembly over the spacer with the shaft facing down.
   • 
   • Use the "Impact Pad" to reinstall the push-on lock washer. Do not bend or damage the washer.
   • 
5. Ensure Correct Fit

Ensure the "Wheel Support" holds the parts securely. The fit should not be tight or loose—either can damage the bearings.
