Here is a step by step guide on how to correctly use the Noble Threaded Bearing Extractor Sets.

This tool is designed to remove bearings by expanding a collet behind the bearing and pulling it out with a threaded rod. This will work on bearings in hub shells, frame linkages and bearings in hubs/freehubs that are separated by a tube spacer/sleeve.

  • Tools Required

    2 x 4mm allen keys, a 13mm spanner & good quality external circlip pliers.

  • Step 1

    Identify the bearing size which requires removal. In this case we have a 6902 (15x28x7).

  • Step 2

    Choose the correct extractor for the bore diameter (15mm) & the correct bearing receiver cup (28mm).

  • Step 3

    Adjust the position of the circlip so the distance between the expanding collets and the circlip is the same as the bearing width you wish to remove. in this case the tool is set to 6mm but we need 7mm wide.

  • Step 3.1

    Remove the black M5 screw (the split collet will stay attached to this) and flip the brass collar over so that it reads 5 7 9 at the top. Then refit the split collet assembly.

  • Step 3.2

    Now grab your external circlip pliers and move the circlip to the correct position. The largest number laser marked on the top of the collar is the bottom position.

  • Step 4

    Insert the correctly set up tool into the bearing, so the circlip touches the bearing.

  • Step 5

    Now using both of your 4mm allen keys, tighten the M5 screw until you meet resistance then a further 1/8th of a turn. DO NOT tighten it more as this could damage the spacer tube separating the bearings.

  • Step 6

    Fit the correct receiver cup, washer and nut. Tighten the nut down using the 13mm spanner, against the 4mm allen key as pictured until the bearing is removed from the hub/freehub/frame.

  • Job Done!

    To remove the bearing from the tool simply back off the split collet using the two 4mm allen keys.

  • No Spacer Tube?

    If you're removing a bearing that doesn't have a spacer tube butted up against it then for Step 5 you can tighten the two allen keys down to fully expand the collets. This still doesn't need to be "tight". Just go until it stops.
