I have this X-Tools crank extractor:
X-Tools crank extractor tool for removing standard Square Taper and ISIS type cranks.
Here's the end that pushes against the crank:
Here's my crank: (it's threaded on the inside, but there's also threading on the narrower bit further in behind the square opening, which my crank extractor pushes against but does not engage with those inner threads...)
I screw in the crank extractor like so:
Then I put an allen key into the crank extractor and try to turn it clockwise, but it's just not budging:
The inner bit of the extractor seems to be pushing correctly against the crank. But do I have the right tools for the job? Am I going about this correctly? Do I perhaps just need more torque than I'm getting off the allen key?
Well, I left what I thought were "dust protectors" off after working on this. During a cycle, my pedal fell off the bike. Here's are a couple of photos for more info:
Now I have to get the pedal on the drive-side off, and will follow up.
