From all I can tell, the TL-FC10 is the right puller for square spindels, but I’m finding that the tip (rotating part) of the puller is about 2 mm too wide to fit into the square hole to push against the spindel. I’ve found various suggestions online, but none seems to have been from anyone who has actually used the puller. I would be extremely grateful for any suggestions. Thanks!
Hi, yes I'm still here.
I never had any problems using my TL-FC10 to pull 105 (FC-1050) and Ultegra square taper cranks from several BB-UN7X and BB-UN5X cartridge bottom brackets, and with the "mushroom tool" insert, it works fine for Octalink (BB-6500) bottom brackets. I have no experience with the BB-1050 Cup-and-Cone type you mention but I see no reason why it shouldn't work.
If your particular combination doesn't work, John's recommendation to use a bearing ball as a spacer is a good one. I expect a small square or hex nut could also be used.
