Bottom Bracket Play(7 posts)

Bottom Bracket Playdaniell

My Ultegra bottom bracket developed play. It only has 1500 miles. It is still under warranty, so I must remove it, and return it to the seller. I am not familiar with the removal of an Ultegra crank. It is a self extracting crank. What tools are necessary to remove the crank? I already have the hex wrench.

Thanks

Use an 8 mm allen and loosen the crank arm allen turning ccw. It will loosen then seem to snug up again, that is the puller at work. With both arms off, make sure the bb cups are tite in the frame. loosen the non drive side, ccw several turns with the park BB tool check with the lbs for the proper # then make sure the drive side is actually tite in the frame. Most Italian bikes turn cw, most of the rest turn CCw to tighten.Then tighten the non drive side back tight clockwise, if there is still play in the bb remove and take to the dealer with your receipt to prove it is under 2 years old. He should warranty, no prob.

Thank you for your kind reply. Should I remove the dust covers before inserting the Allan wrench?

The "dust caps" are retaining rings. Leave them in place, unless they have fallen out already. See Spline Type Crank Removal. For bottom bracket removal see Cartridge Bottom Brackets.

I was able to remove the arms once I realized that the dust cover was necessary. I was not familiar with the self extracting cranks . My previous road bike had Campi Record cranks. Once the arms were off, I then realized that the problem was not a faulty bottom bracket, just a loose one. I was only able to tighten the left side. My tool would not fit into the right side. I found out that I needed a different tool, that will fit both sides. I wonder if just tightening the left side will sufice.
