Ultegra Cranks - Please help!!!(4 posts)

Ultegra Cranks - Please help!!!MW
Jan 26, 2002 6:40 PM
I have a problem....I was taking my ultegra cranks off of my bike(which I have done hundreds of times) and the Alloy self extracting bolt out of the BB, and it cracked. Which means the cranks arm is still on the bike. Has this happened to anyone? How can you get an Ultegra crank arm off, if you don't have a self extracting bolt?

Please help

did the bolt crack???? seems unlikly... or the top cap? if it's the top cap then you just need to back it out and get a new set, then put it back in and your all set. If it's the bolt, then remove the bolt and wander down to your LBS and buy a crank arm removal tool. (you should have one anyway) then install the tool and crank away. It's pretty self explanitory (using the tool).

You could remove the arm with a hack and bash approach, but the tool is cheap and MUCH nicer to your crank and bike...

Good luck

... assuming that you've removed the crankarm bolt... Park makes a special extractor for splined BB spindles...

Shimano make a special plug to insert in the bolt-hole of the splined shaft (part TL-FC15) - you can then use a normal crank extractor to pull the crank. Your LBS shld have this plug - it comes supplied in the crankset package.
