BB92 (BB86) Removal & Installation (Tool & Technique)

Remove or Install a BB92 (or BB86) bottom bracket with a unique toolset https://www.firstcomponents.com/bike-...

The bearing cups are aluminum alloy. They’ll go into an alloy frame with an alloy bb shell so a little grease is necessary for smoother installation and removal. The retaining cup braces the non-install side during installation. This connects directly to the bb cup being installed
The twenty-four millimeter side fits into the bb92 cup with the twenty-two millimeter side facing out. You install one cup at a time starting with the drive side. Once it’s finger tight you can finish the job with the eight millimeter allen wrench. Four or five turns presses it in
Then loosen the bolt remove and prepare to press in the non-drive side cup. You install this in exactly the same way. Once you’re done pack the tool away ready for the next job. The complete procedure takes a few minutes at most. The smaller of the two steel split hitches mounted onto the driver is required to remove a bb92 bearing cup. You’ll also need the retaining cup and the bb shell ring. The split steel hitch goes on the driver inside the bearing cup as so but you need to install the driver first then install the split steel hitch onto it inside the bearing cup. The split steel hitch expands over then locks onto the end of the driver. The retaining cup holds the bearing cup when it’s pushed out of the bb shell. The bearing cup pops free of the bb shell and can be extracted in one movement. Repeat the procedure for the drive side
