Swapping D-A Hollowtech Cranks
 

Any special tools required to swap Dura-Ace Hollowtech cranksets?

Must one remove the BB-cups, or is it simply a matter of loosening and removing the none-drive side crank and sliding the drive-side out?

Thanks in advance for any guidance (or smart@$$ remarks, as long as they're funny.)

You need the plastic "tool" to undo the pre-compression nut at the left end of the spindle. It comes integrated as the end of Park's BBT-9, but also comes alone some places. You undo the 2 hex nuts on the left-side arm, undo the pre-compression nut with the tool above, pull out the left arm, and then pull out the right arm with chainrings and spindle all in one.

Edit: The plastic thing is Shimano part # TL-FC16. Worth 2-3$ most places.

Here are some good directions
