johnridleyJust into today's ride to work, I couldn't get my right foot positioned correctly on the pedal (I'm using platforms and hunting boots until it warms up a bit). My heel kept hitting the chainstay, and it felt like I had a chunk of ice stuck to my boot. About halfway to work it got ridiculous, and I stopped to check it out; the pedal had stripped and worn the crankarm hole out; I could wobble the crank around and pull it out by hand.
I turned around to go home (5 miles home beats 15 miles to work and back) and got about 1/4 mile before the pedal fell out, not to be replaced.
4 miles over hills with one pedal isn't much fun, but at least it's way faster than walking.
Then I made a mistake with the crank puller tool and stripped the threads on the puller socket. I called the shop and he said to just bring it in and he'd get it off somehow. J suggested using a dremel tool which is what I'd probably do if I had to do it, but I have to get to the shop to get the crank replaced anyway, so I think I'll just let them do this one.
I'm sure the threads got wrecked when I changed the Shimano clipless pedals out last week for the PowerGrips; I had to use a big wrench and stand on it to get the old pedals out. I probably should have used a torch and heated the crank first to expand the aluminum a bit, since I was turning the pedals out in about 5*F weather. For sure I'm putting anti-seize compound on the thing for the new crank.

Date: 2007-02-17 02:10 am (UTC)I took the bike to the shop, and he couldn't it out either. I'm not sure why he was so confident; he doesn't have any different tools than I do for this purpose. He was about to take a really long time (and a really large bench fee) to do a long drawn out heat-based removal; I said "No, just sell me the crank and I'll deal with it." He was skeptical but I left with a new crank in hand.
At home, I cut a slot with a grinding disc as deep as I could go, then drilled a few holes the rest of the way, wedged an oversized screwdriver in there (the kind that's really only used as force devices AFAIK) drove it in with a hammer, and the thing popped right off.
I put the SPD pedals back on the new crank (after cleaning the threads on the wire wheel) - hopefully it'll stay above 0*F for the rest of the winter so I can stay away from the platforms & boots. The new crankset is a definite step up, and I'd rather not wreck it RIGHT away.
