I got my hands on a pair of obviously pretty well used Shimano 600 pedals. They looked to be be in decent shape, but didn't spin smoothly. I took them apart, cleaned everything and then bought new bearings (these are open bearings). I put the new bearings in and used grease for bearings that I bought at PEP BOYS. They now look great, but still don't spin well.
So, what have I forgotten to do, or done wrong, etc.?
