I'm a terrible mechanic. I lose stuff, break stuff, or injure myself all the time. I watched the videos and read the pedal chapter (thats how bad I am) and was warned it might be tough. The left pedal wasn't too bad. The right pedal was sprayed with WD40 and heated to no avail. I put my weight into it while the left crank was blocked from moving by the kickstand and my other foot. It finally broke free after multiple slips and bangs. I noticed the top 2-3 threads have blue stuff on them. Do bikes come preassembled or do bike shops put them together?? I can assume the bike shop used LocTite?? Anyway, will clean the crank threads, grease the new spindles and reassemble.
