I have a stock 2010 Surly LHT. I purchased a 24t granny and a crank puller, but when I went to remove the crank arm, it would not budge. The 8mm preload bolts were on super tight. I had to use a cheater bar to get them loose from the spindle, and the threads were greased when I finally got them off.
When I went to pull the arms off, I could not get them removed with the puller. The one I purchased is the Park CCP-22 (linked above) with the lever arm integrated to the extraction bolt. My questions are:
1. Should I go get a crank puller that I can use a longer wrench on, or will I risk stripping the threads on the Aluminum crank?
2. If I do get them off without damaging them, can I re-install them without risking future problems?
3. Will I have to torque them just as tight as they were to give them sufficient pre-load and prevent loosening, or can I put them back on using the specified torque ranges?
The bike is only 2 years old, with about 3000 miles on it. The bike is well-taken care of, but I do live in Portland so by extension, the bike has seen a fair share of rain and grit. I have full fenders and a mudflap that goes all the way to the ground so it's probably not as bad as you think.
