Thanks for the link. I followed the instructions and managed to get it all apart, bearings cleaned up and re-greased, and I re-chromed the crank. I lightly sanded and re-used the cotters in the exact same orientation as before, taking care to install them opposite from each other so the crank arms are 180 deg apart. I am now having trouble getting the sprocket far enough away from the frame to allow the chain to be installed without hitting the frame. Considering all parts are the same as before with the exception of the slightly sanded cotters, would it be possible they are causing my clearance issues? I am not sure how else to attack this as the bottom bracket has very little side to side adjustment as well.
Thanks again.
