Well today I tried some creative mechanics trying to remove my new 105 cranks. I didn't have the Park puller for splined, all I had was a Lifu one. So got this crazy idea, that if I could just stick something in there to push on the axle edge while I turned the puller it would pull the crank off.

Insert copper penny!

So after several good turns it dawns on me that the crank is not coming off. Well. I removed the puller only to find that the penny and part of the puller is sandwiched into the hollow part of the axle! AAAAHHHHHH!!!!! :eek:

Fortunately for me, the sandwiching was not that bad and I was able to remove the pieces, and inflict no damage to the crank or axle.

I laugh now, but damn that could have been ugly.

Anyone else have stories of similar workshop blunders?

Pick up a "105 tool", it will fit in the axle and is just a couple of bucks.

Having a crank puller is better, Park Tools sells them for $15 or so. Or you could get the self extracting retainer bolt. Some industrial designer at Shimano had an epiphany and realized that a minor design change in the cap would convert it to one that extracts the crank from the BB. They are less than $10 and aftermarket versions were recently mentioned in Bicycling or Mtn
