So, armed with a crank extension pole and no clue … I’ve over tightened the crank bolt of my fsa energy (stages) power meter to the point that the bolt has sheared itself free from it’s surrounding ring and borrowed itself deep into the spindle. Said bolt is also rounded at the threads and stuck to…

Could try differentially heating it; though with an all metal assembly it’d be pretty hard / elaborate (and may or may not work). I’d probably find the largest hex bolt that fits inside the spindle, keep it in a freezer for a few hours, gently heat the end of the the crank (I’d probably submerge th…

Thanks folks, I’ll try the wiper puller tool first. Great idea!

I had one (a FSA crank) about 10 years ago, so my memory could be hazy. IIRC it worked a bit like a inbuilt crank extractor. The OP looks to have managed to burst the top bit of it out. But if a non inbuilt extractor won’t fit, my idea won’t work. Perhaps a lbs might have something to help …

Faced with this type of problems, there are 3 types of human beings: the Hitters, the Drillers and the Pryers. The Hitters think every problem can be solved with a hammer. Stay away from them. The Drillers can be pretty good, if they are well-equipped and well-trained. But by definition they destroy…

Edit: Never mind, just discovered that FSA use an M27 extractor thread. I read on on forum that this is the same size as a Cannondale Si/BB30 puller, but others say that’s M30. But I did find this: a bung for the end of the spindle

Success!!! I reached out to the tech department in my school (I’m a teacher) to see if they had any pullers. They didnt have any that fit, but Mr Phipps is definitely a hitter! He rested it in a vice with the spindle pointing down, and used a chisel to hammer the buggered bolt. The spindle popped o…

Proving me wrong - sometimes a Hitter will provide a good solution. The chisel is an essential component of a Hitter toolbox. And of course my analysis was short on all the variants that can mix in, such as Heater-Freezers and the unstoppable WD40 Sprayers.

Not to mention, the dreaded angle-grinders.

Would an old fashioned crank removal tool fit? If so you could screw that into the crank arm threads then gradually adjust it to push the crank arm off the spindle.
