Replace the bearings on a 68 * 122.5 sealed cartridge bottom bracket

Hi people,


I own a Decathlon BTWIN Rockrider 340 bike and it has done close to 2500kms. I recently heard creaking noises while pedaling and have decided to rebuild the bottom bracket.

These are the specifications, VP-BC73 sealed cartridge bottom bracket with a size of BC1.37" x 24T (68 x 122.5).

The bearings that have worn out are both a 9002RS and I see that these bearings are non standard, meaning I can't be able to find these at a bearings shop easily.

Also before I get there, I do not know how I can pull these bearings off the square taper spindle as the spacer thingy which is between stops me from placing a 3 prong bearings puller to pull it out.

Could anyone suggest any hack here? I will be doing this for the interim after which a replacement of the BB is certain, but I just want to be sure that I do the re-packing of the grease on both sides of the bearing before I put these back on the bike.


Thanks in advance.
