Left Crank Bolt Issue
I commute to work on a Peugeot Road Bike setup as a single speed. Have had for a few months now. No issue, other than the occasional fluctuation in tire pressure.
Anyway, I tried googling the answer and found a lot of posts concerning loose left crank arms, broken arms, stripped threading, etc. It was somewhat helpful but like everything, this is a case-by-case situation. Here's what's going on:
So last Tuesday morning I woke to find my dad cleaning his bike. He told he had sprayed some WD-40 on my hub to stop the small reaking that had shown up every now & then. It worked. He alsowent ahead and told me he blasted some of it on metal pieces that the crank arms sit/hold on (mind you, I don't know tooooo much about bikes, so I apologize if I don't know the proper term to e used). Anyway, the bike was fine on my way to work,but on the way back........
Halfway back home later that day,while listening to my iPod, I felt a slight wobble on my leg. I thought nothing of it. As I continued for about 4 more blocks the wobbling increased. At this point I stopped, got off the bike and analyzed the situation. The bolt had come loose & not having an 8mm on me, I had to resort to taking the bus home. Left the bike @ home the next morning. I bought a Crank Bros. multi-19 the next day on my way home.
Today was the first day back on the bike. Although not as significant, the bolt keeps coming loose a bit. Can't figure it out. The mounts seem fine,the square metal it rests on hasn't been rounded and they fit snug. The thread on the bolt seems fine. I'm stumped. I have a hunch,do you think theWD-40 contributed & os still the reason I'm having this issue. Any insight on this would be greatly appreciated.
P.S. Sorry about the long-ass post. I just thought you should know the FULL story, so that I may get a proper explanation to my problem. Thanks :-D
