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.
