crank has kicked the bucket
5 years ago when I bought the bike I put on these new pedals, I only threaded them in half way by hand(seeing as how I was so exsited), when I started to pedal half the threads connecting the pedal to the crank(on the left side) were yanked out, and all I had left were 4 or 5 threads left to hold in the pedal. Well after years of riding the threads on the other side are starting to give way. Can new threads be machined in? What can I do to save my crank? BTW, It's made if alloy!
